Machine for textile and garment production.
Flatbed machines may be hand-operated or power-driven, and, by selection of colour, type of stitch, cam design, and Jacquard device (see Jacquard loom ), almost unlimited variety is possible. Modern circular machines may have 100 feeders, allowing each needle to pick up 100 threads per revolution. Both spring (invented 0441; 1589) and latch (invented 1847) needles are used, with the latter more common. Small bladelike units (sinkers) are inserted between every two needles to engage and hold the completed fabric. Machines may have pattern wheels controlling needle action to produce special stitches, and also a Jacquard mechanism. See also William Lee .
