Abstract
A work manipulating mechanism for a sewing machine attachable to the presser bar thereof which utilizes a pair of spaced apart endless belts on a first drive plate to feed an endless quantity of work material through a sewing machine in the formation of an ornamental pattern or monogramming, the first drive plate being shiftable in an orthogonal direction by a second drive plate attachable to the presser bar of a sewing machine. The first drive plate may be shifted by a rack and pinion connection to a stepper motor supported on the second drive plate, and the work material may be shifted by a stepper motor connected to one of a pair of shafts carrying sprockets encircled by the endless belts in contact with the work material.
Claims5
A work manipulating mechanism for use with a sewing machine having a frame supporting a presser bar, a needle bar, a sewing needle supported on the end of said needle bar, means for supporting said needle bar for endwise reciprocation, actuating means for implementing endwise reciprocation of said needle bar, said frame including a work supporting bed;
- and an electronic control means for storing signals related to positional coordinates for patterns and monograms, said mechanism comprising:
- first means responsive to said signals from said electronic control means for selectively feeding work material in unlimited amount along one axis intermittent generation of stitches;
- and,
- second means responsive to said signals from said electronic control means for selectively moving said first means along an axis substantially orthogonal to said one axis intermittent generation of said stiches.
A work manipulating mechanism for use with an electronically controlled sewing machine having a frame supporting a presser bar, a needle bar, a sewing needle supported on the end of said needle bar, means for supporting said needle bar for endwise reciprocation, and means for storing electronic signals related to positional coordinates for patterns and monograms, said frame including a work supporting bed, said mechanism comprising:
- first means responsive to said electronic signals for selectively feeding work material in unlimited amount along one axis intermittent generation of stitches;
- and,
- second means responsive to said electronic signals for selectively moving said first means along an axis substantially orthogonal to said one axis intermittent generation of said stitches.
