Circular Knitting Machine Product

Overview

A circular knitting machine produces tubular weft-knitted fabric on a rotating cylinder of latch needles. Yarn is drawn from cones on a side creel, tensioned and metered at each feed position, and worked into stitches as the cylinder turns past a ring of stationary cams. The fabric forms as a continuous tube that is drawn downward, spread, and wound into a roll. This model is a 30-inch, 24-gauge machine with 96 feeders, capable of single-jersey, rib and interlock structures depending on dial setup.

Yarn leaves the Side Creel and runs through the Yarn Feed System system, where a positive feed wheel and disc tensioner deliver each end at constant rate to the needles. Color-change striping fingers at selected feeds allow patterned courses.

How it works

The heart of the machine is the Needle Cylinder, a grooved steel cylinder whose tricks each hold a latch needle. As the cylinder rotates, needle butts ride the tracks of the Cam System: knitting cams raise each needle to clear the old loop, then lower it to draw new yarn through, while sinkers hold the fabric down between needles. The Dial Assembly carries radial needles that interlock with the cylinder needles to knit rib and interlock fabrics.

Rotation comes from the Main Drive, an inverter-fed motor turning the cylinder through a reduction gearbox and a large ring gear that sets stitch speed. Below the needles, the Take-Down & Batching draws the fabric tube down under controlled tension and batches it onto a cloth roll.

Continuous running depends on supporting systems. The Lubrication System sprays an oil mist onto the needle and sinker tracks to cut friction and wear at speed. The Lint Removal System blows fly and lint clear of the knitting zone with a rotary blower and air ring. The Stop Motion & Sensors watches every feed for a yarn break and halts the machine on a fault before a hole or press-off can form, protecting both fabric and needles. ', },

Overview

A computerized embroidery machine stitches digitized designs into fabric by moving a hooped panel under a bank of fixed needles while a synchronized lockstitch is formed at each penetration. This is a six-head machine: each head carries twelve needles for automatic color changes, and all six embroider the same design in parallel, so production scales with head count. The design file drives an X-Y pantograph that positions the fabric to a tenth of a millimeter between stitches.

The fabric is held in hoops mounted on the Pantograph & Hoop Holders, which the X-Y Hoop Drive moves on two servo axes. Thread runs from the Thread Cone Stand down to each sewing head.

How it works

Every Sewing Head forms a lockstitch. As the needle descends through the cloth, the rotating Rotary Hook & Bobbin Case beneath the bed catches the loop of upper thread and carries it around the bobbin, locking the two threads in the fabric. The needle bar case shifts laterally to bring the selected color needle into the sewing position. A thread take-up lever pulls each stitch tight, and disc tensioners set thread tension.

All heads run from one Main Shaft Drive: a main motor turns a shaft spanning the machine through a gear and belt, with an encoder reporting shaft angle so the controller fires hoop moves and trims at the right instant. The X and Y servos in the X-Y Hoop Drive run on ball screws and linear guides, jogging the fabric one stitch step while the needles are clear.

The Control Panel panel reads the design, sequences color changes, and drives the motion. A thread-break sensor on each head stops the machine and flags the position when an end runs out or breaks, and the Lubrication System keeps the high-speed hooks and shafts lubricated. ', },

Overview

An automated fabric cutter cuts stacked plies of spread fabric to pattern shapes under CNC control. A reciprocating knife on a moving gantry follows the marker geometry while a vacuum holds the plies flat and motionless against a penetrable bristle bed. Cutting many plies at once, the machine replaces hours of hand cutting and holds shape accuracy across the whole spread. This model cuts up to 1,800 mm wide on a conveyorized bed, advancing the spread so cut length is effectively continuous.

The spread plies rest on the Conveyor Bed, a bristle-block conveyor the blade penetrates into. The Overlay Spreader lays an overlay film over the stack so the vacuum can seal it.

How it works

The X-Y Gantry is a bridge spanning the bed, carrying the cutting head on two servo axes: the gantry beam moves along the table while a carriage runs across it, positioning the head anywhere over the spread on ball screws and linear rails.

Cutting is done by the Cutting Head. A hardened reciprocating blade is driven by a crank that converts motor rotation into rapid up-and-down strokes; a theta axis rotates the blade to keep its edge tangent to the cut path, and a Z axis sets penetration depth. A built-in Vacuum System holds the plies down: zoned blowers pull air through chambers that follow the head, so suction concentrates where the blade is working.

Edge quality is maintained automatically. A grinder in the head re-sharpens the blade on a set schedule, a drill unit punches reference holes, and a presser foot keeps the top plies from lifting. The Control Cabinet holds the motion controller, servo drives and operator touchscreen that run the marker, and a Laser Projector projector shows operators where to place parts on the spread. ', },

Overview

An industrial steam press finishes garments by clamping them between a padded lower buck and a heated upper head, injecting steam through both faces to relax the fabric, and then pulling vacuum through the buck to set and dry the press. The combination of heat, moisture and pressure produces a sharp, durable finish far faster than hand ironing, which is why presses anchor the finishing line in laundries and apparel factories. This unit carries its own steam generator, so it needs only electricity and shop air to run.

The garment is laid on the Steam Buck, a contoured form with internal steam chambers, an auxiliary heater and a replaceable woven cover over heat-resistant padding. The Steam Head is the heated upper platen that closes onto it.

How it works

Steam comes from the Steam Generator, a pressure vessel heated by immersion elements and kept topped up by a feed pump under control of a pressure switch, with a safety relief valve and a dry-fire thermal cutoff. From there the Steam Circuit routes steam through solenoid valves and braided hoses to the head and buck on operator demand.

The press is closed by the Press Closure: a double-acting pneumatic cylinder drives an over-center toggle linkage that multiplies air pressure into clamping force, and return springs lift the head when air is released. The operator works the Foot Control pedals, keeping both hands free to position the garment.

After steaming, the Vacuum System system draws air through the perforated buck to extract residual steam and dry the fabric so the crease holds. The Control System system ties it together, switching heaters, valves, pump and blower through relays, holding platen and buck temperature via thermostats and thermocouples, and timing the press and steam cycle.

'overlock-serger': { specs: [ ['Type', '4-thread industrial overlock (serger)'], ['Threads', '4 (2 needles + 2 loopers)'], ['Needles', '2'], ['Max speed', '7,000 stitches/min'], ['Stitch length', '0.8–4.0 mm'], ['Stitch width', '4–6 mm overedge'], ['Differential feed', '0.7:1 to 2.0:1'], ['Needle type', 'DCx27 / DCx1'], ['Drive', 'Direct-drive servo motor'], ['Knife', 'Top-and-bottom edge trimmer'], ['Lubrication', 'Automatic sump oil pump'], ['Needle stop', 'Position-controlled (up/down)'], ['Power supply', '220 V single-phase, 50/60 Hz'], ], body: '

Overview

An overlock serger trims a fabric edge and wraps it with thread in a single pass, producing the finished overedge seam used on knits and the inside of most garments. Twin needles, an upper looper and a lower looper interloop their threads around the cut edge while a knife trims the fabric just ahead of the stitch, so cutting and sewing happen together at high speed. This is a four-thread industrial machine running up to 7,000 stitches per minute on a direct-drive servo.

Power comes from the Servo Drive Motor, an energy-saving servo that turns the handwheel pulley and the Main Drive Shaft, whose timing gears drive the needle, looper and feed mechanisms in phase.

How it works

The Needle Mechanism reciprocates two needles through the fabric while the Looper Mechanism swings an upper and lower looper, driven by eccentric cams and links off the main shaft, to carry thread around the edge and interloop with the needle threads. Just ahead of the needles, the Trimming Knife Mechanism trims the fabric to a clean edge: a moving upper knife shears against a fixed lower knife so the overedge stitch always wraps a freshly cut line.

Fabric is advanced by the Differential Feed Mechanism, a differential feed with independent main and differential feed dogs. Setting one dog to move faster than the other gathers or stretches the fabric as it sews, which is how knit seams are kept flat without waving or puckering. Thread runs from the Thread Path, a four-cone stand feeding through tension discs and the threading tree.

Running clean at speed depends on the Lubrication System sump pump, which oils the high-speed shaft and looper drive, and the Control System system, where a board reads the foot pedal and a needle-position sensor to govern speed and stop the needle up or down. ', },

Overview

A power loom weaves cloth by interlacing warp and weft yarns at high speed under program control. This is an air-jet loom: instead of a shuttle, a jet of compressed air shoots the weft thread across the warp shed, allowing very high pick rates with no heavy reciprocating carrier. A heavy frame carries the warp let-off, the shedding motion that opens the warp, the air-jet insertion, and the reed that beats each pick into the cloth, all sequenced by a controller from the warp beam through to the cloth roll.

Warp yarn is delivered by the Warp Let-Off, which meters thousands of ends off the warp beam under closed-loop tension control, sensed by a load cell on the back rest roller.

How it works

Each weaving cycle begins with shedding. The Shedding Motion motion is an electronic dobby that lifts selected heald frames in programmed order, splitting the warp into an upper and lower sheet to open a shed. The Air-Jet Weft Insertion system then fires a pick across: a main nozzle launches the weft and a row of relay nozzles along the reed relay the air stream to carry it the full width. The Weft Feed accumulators meter exactly one pick length, and an optical sensor confirms the weft arrived before the next cycle.

With the pick laid in, the Reed & Sley sley swings the reed forward to beat the new weft up against the cloth fell, and the next shed opens with the frames reversed to lock the yarn in. The Cloth Take-Up advances the finished cloth at the set pick density over an emery roller onto the cloth roll, while leno and tuck-in devices form a firm selvedge at each edge.

Two protective systems guard quality. The Warp Stop Motion motion drops a wire onto an electric bar the instant a warp end breaks, halting the loom. All of it is timed by the Loom Control System system, which reads a main-shaft encoder and sequences insertion, shedding and beat-up to a fraction of a degree. ', },

Overview

A ring spinning frame turns roving into finished yarn by drafting it to the required fineness, inserting twist, and winding it onto a bobbin, all continuously and on hundreds of spindles at once. It is the dominant short-staple spinning machine: the ring-and-traveler that twists and winds the yarn is simple and robust, and a long frame like this runs 480 spindles from one drive. Roving bobbins hang in an overhead creel, the fiber is attenuated in a roller drafting zone, and each end is spun down to a cop on its own spindle.

Roving feeds from the Creel into the Drafting Section, a three-over-three roller system with double aprons that grips the fiber strand between roller nips and pulls it thinner as it passes, setting the final yarn count.

How it works

The drawn strand leaves the front rollers and runs to a spindle in the Spindle Position. Every position is a spindle carrying a bobbin, driven by a tangential tape off the tin roller and spun at up to 18,000 rpm. Twist is inserted by the Ring Rail Assembly: a C-shaped traveler rides freely around a hardened ring, dragged by the yarn. Each lap of the traveler around the ring puts one turn of twist into the yarn, and because the traveler lags the spindle it also winds the yarn onto the bobbin.

Building a well-shaped cop needs coordinated motion. The builder motion reciprocates the ring rail up and down, laying yarn in layers, while the Yarn Guide Rail lappets center each end over its spindle and balloon rings restrain the spinning yarn balloon at speed. Power for all of it comes from the Main Drive, whose motor and gearbox turn the tin roller and the roller line through change gears that set draft and twist.

When the bobbins fill, the Auto-Doffer strips every cop and re-tubes the spindles automatically. The Pneumatic Suction System sucks away broken ends and fly through per-spindle pneumafil nozzles, and the Control System monitors every position for a broken end. ', },

Overview

A carpet tufting machine builds pile carpet by punching yarn-threaded needles through a moving backing cloth and catching each loop underneath, repeating across a full broadloom width hundreds of times a minute. It is the fastest way to make carpet: where weaving interlaces yarns, tufting simply inserts pile into a ready-made backing, so a five-meter machine can produce broadloom at a rate no loom matches. Loopers below the bed decide whether each insertion stays a loop or is cut into tuft, giving loop-pile or cut-pile carpet.

Yarn runs from the Yarn Creel & Feed-In, floor-standing racks of hundreds of packages feeding through guide tubes and tension gates so every end enters at even tension, into the working head of the machine.

How it works

The Needle Bar Assembly holds a full-width bar of needles, reciprocated up and down by eccentrics and push rods off the main shaft. On each stroke the needles punch the threaded yarn through the backing cloth. Beneath the bed the Looper / Hook Bar Assembly swings hooks up to catch each loop in time with the needles; for cut pile the hooks pair with reciprocating knives that slice the loops open into tuft.

Pattern and pile height come from the Pattern Yarn Feed. Banks of servo-driven scroll and roll feeds meter each group of ends independently, so the controller can starve or feed yarn to vary pile height and place color across the width. The backing is moved through by the Backing Feed & Take-Up, driven feed rollers pulling the primary backing across the bed under the needles while take-up rollers wind off the finished carpet.

All shafts run from the Main Drive, an inverter-fed motor turning the main and looper shafts through a gearbox and belt, with a clutch and brake to start and stop on the stitch and an encoder feeding shaft angle to the controller. The Pattern Control System system runs the design, syncing the main drive with every yarn-feed servo, while the Lubrication System pump keeps the needle, looper and shaft bearings oiled.
