The invention pertains to a blind-stitch sewing machine with a plate-shaped fabric bender to make a sewing material bulge in to the arcuate path of an arc needle. The fabric bender extends in a plane perpendicular to the path of the arc needle and is pivotable to-and-fro in this plane by means of a drive shaft extending perpendicular to this plane. The fabric bender is rotatably supported in a slot of a support assembly projecting from the drive shaft to pivot about an axis parallel to this drive shaft, and furthermore is spring biased away from the drive shaft. To achieve a narrow construction of the fabric bender and of its support assembly, the drive shaft is hollow and a torsion spring is provided to load the fabric bender. The torsion spring is mounted in the borehole of the hollow shaft where adequate space is available to install the spring.

Stitch shortening and tacking assembly

STITCH SHORTENING AND TACKING ASSEMBLY ABSTRACT OF THE DISCLOSURE A stitch shortening and tacking assembly for use in a sewing machine is provided. The shortening and tacking assembly is particularly suited for use with a sewing machine wherein a fabric is advanced between a presser foot and a platten disposed in a first feeding position by a reciprocating feeder that is synchronized with respect to a rib and sewing needle. The sewing needle is synchronized with respect to the feeder and rib to stitch the fabric after the web has been advanced by the feeder. The platten is adapted to be displaced from the feed position to a stitch shortening position whereby the web is advanced through a shorter interval between sewing operations to thereby shorten the length of each stitch effected thereby. The platten is further adapted to be displaced from the stitch short-ening position to a stitch tacking position whereby a portion of the platten is biased against the presser foot to thereby prevent the fabric from being advanced between sewing operations.

Control mechanism for sewing machine

This disclosure relates to a control mechanism for a blindstitch tacker wherein a single control device is provided for progressively moving a node former and work clamp of a sewing machine into clamping engagement with a workpiece, and further movement of the control mechanism results in the initiation of the stitching operation. The control mechanism includes a multiple lever arm bell crank with different ones of the lever arms thereof actuating different mechanisms of the sewing machine. The control mechanism also includes a cam and cam follower for actuating the node former and work clamp with there being an overcenter position wherein further movement of the bell crank does not result in further movement of the node former and work clamp. When the bell crank has moved to this position, a spring retains the bell crank in its operative position without assistance by the operator. The control mechanism is automatically returned to its inoperative position upon the termination of a predetermined sewing cycle.

Lacing apparatus with feed rollers to smooth creased crimped material after lacing

Apparatus for lacing a flexible line through sheet material, such as shade cloth, of an indefinite length in a continuous operation. The apparatus has a set of pleating rollers, each with a series of teeth spaced apart about the periphery. The pleating rollers are mounted for rotation so that the teeth intermesh in a mesh zone, sheet material feeding through the mesh zone during apparatus use being caused to fold by the teeth into successive pleats. A lacing needle projects toward the pleating rollers and has a leading end positioned in the mesh zone. Sheet material pleats successively formed in the mesh zone are pierced by the leading end and received onto the lacing needle. The lacing needle is collectable to a flexible line for lacing through the material. A set of feed rollers are positioned downstream of the pleating rollers, each with a circumferential groove and being mounted for rotation so that the circumferential grooves are in register one with another. The lacing needle is positioned in the circumferential grooves and supported by the feed rollers. Rotation of the feed rollers strips the sheet material from the lacing needle and onto the flexible line so that the line is laced through the sheet material.
