Embroidery Machine

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.
