A sewing machine includes a material sandwiching unit to sandwich two materials having annular edges from above and below while they are stacked so that the material on an inner wheel side is located on the lower side and the material on an outer wheel side is located on the upper side, wherein a part of the material sandwiching unit located above the two materials is vertically movable, the material sandwiching unit includes a curl-removing mechanism to straighten curls occurring on the edges of the two materials, the material sandwiching unit includes inclined parts that serve as the curl-removing mechanism and have edges extending backward from a farther side of the edges toward the edge side at a position where the two materials pass therethrough, and the inclined parts have air ejectors to eject air so as to form airflows that straighten portions of the materials where curls have occurred.

In an overedge stitch type consisting of two needle threads, one looper thread and a workpiece carrying these threads, loops of the needle threads are arranged at different spacings parallel to the edge of the workpiece within the latter. In addition, these loops of the needle threads may also exhibit different spacing from the workpiece edge.

The needle plate assembly comprises a walled needle plate having a compound needle hole for passage therethrough of a thread, and having a minor attachment arm portion to provide a lateral right angle aperture in the needle plate for a thread staying block which is subject to the force of a spring with the thread staying block projecting from the needle plate through the right angle aperture to be proximally engaged by respective needles.

In the production of knitted garments especially pullovers, cardigans and sweaters it is frequently desired to add a knitted strip of material to the garment to define a neck opening. With this invention a first piece of fabric such as the strip is impaled on the points of a linking machine, the second piece of fabric such as the garment is then impaled on the points and the other marginal edge of the strip folded over the second piece of fabric and with said marginal edge abutting the points the two pieces of fabric are sewn together. When the strip has one marginal edge formed as a welt edge it is that edge which is impaled on the points.

A looper for connecting a plurality of knitted parts suspended on a needle ring by means of two chain-stitched seams. One of two sewing needles required for producing the chain-stitched seams is displaced laterally above the stitches supported by knitting needles of the needle ring. Both of the sewing needles required for producing the chain-stitched seams enter at least one row of stitches above the stitches supported by the knitting needles of the needle ring.

Mounting means for a sewing machine, or a similar machine for joining together pieces of fabric, having a horizontal work surface by which the machine is supported with capacity for rotation about a vertical axis. The machine is mounted within an aperture formed in the horizontal surface, and supported by bearings. A vertical shaft, located below the work surface, is connected to the machine and provided with a disc, whereby the machine is rotatable from beneath the work surface. Shelves and compartments are located beneath the work surface for storage of materials and for housing the control circuitry for the machine. The invention eliminates the customary stand on which such machines are mounted, and the many disadvantages attendant thereto.

The invention relates to an apparatus for closing the opening formed at or near the toe end of a circularly knit stocking which is knit from a yarn forming a stocking web, where a bead is provided along the edge of said opening. The apparatus has a guiding channel with a longitudinal slot, through which channel the superposed bead halves are advanced from one end to the other, the stocking web extending through the slot of the channel. Before the closing operation the stocking is taken over by a clamping device consisting of a stationary table and a rotating presser foot between which the stocking web is clamped so as to be advanced past a seaming station by the rotation of the presser foot. The guiding channel is continued along part of the contour of the clamping device, but ends at some distance from the seaming station.

In an apparatus for the closing of the toe of a circularly knit stocking along a looper-line, a pair of jaws are provided which between them form a guiding slot into which the juxtaposed halves of the bead along the non-closed opening of the stocking may be pushed, the apparatus further comprising gripping means to grip the stocking as held between the jaws whereupon the latter are spread apart and withdrawn and the gripping means move the stocking past a working position in which trimming and stitching means are provided.

A looping machine wherein a sewing needle engages in a groove on the underside of the row needles on the side corresponding to the downwardly hanging section of material into the looping material for the purpose of stitch formation. The entire drive for the sewing needle is disposed below the crown of the row needles.
