Stretch stitch geometry is specifically for stretchability. While the needle is moving, as for straight or zigzag stitches, the feed dogs automatically move the fabric forward and backward. As with zigzag stitches, stretch stitching is controlled by mechanical cams, but because of the dual action, stretch stitch machines have double cams. As ...
Schiffli machines evolved from, and eventually replaced manually operated "hand embroidery" machines. The hand embroidery machine used double ended needles and passed the needles completely through the fabric. Each needle had a single, continuous thread. Whereas the schiffli machine used a lock stitch, the same technique used by the sewing ...
Singer made an attachment similar to its buttonholer, and using a similar needle-clamp-powered locomotion, in order to confer some zigzagging ability on its straight-stitch machines. Of the variety of "Singer Automatic Zigzagger" attachments produced over the years, two are compatible with 27-series machines: Singer part numbers 160985 and 161102 .
Multi-needle refers to fact that the machine has up to two rows of needles. Each needle creates a copy of the design. The satin stitch is created by passing the threaded needle completely through the fabric. The hand machine is the predecessor of the schiffli embroidery machine. The schiffli machine creates a lock stitch similar to a sewing ...
In 1983, Tajima created the TMLE Series Multi-Head Electronic Lock Stitch Chenille Embroidery machine, followed by the TMEF Series 9-needle Type Electronic Embroidery Machine in 1984. In 1986, Tajima introduced the world's first sequin embroidery machine, enabling designers to combine sequin embroidery with plain embroidery.
Vibrating shuttle machines reciprocate their shuttle through a short arc. The earliest vibrating shuttles used boat-shaped shuttles, but bullet-shaped shuttles soon replaced them. The design was popularized in the White Sewing Machine Company 's ' White Sewing Machine ' and Singer 's 27-series machines . [ 5 ]
It is a back-and-forth stitch used where a straight stitch will not suffice, such as in reinforcing buttonholes, in stitching stretchable fabrics, and in temporarily joining two work pieces edge-to-edge. When creating a zigzag stitch, the side to side motion of the sewing machine's needle is controlled by a cam. As the cam rotates, a fingerlike ...
The Serpentine machines formed a lock stitch using a reciprocating (i.e., linear fore/aft motion) boat shuttle, while later models used a vibrating shuttle. The B model received the 1884 Northampton Leather Exhibition prize for the best machine for closing boot uppers and general leather work. [16] The CS Family model was produced for many years.
