摘要:
A resilient band (10') for use with articles of apparel, the band is formed with a first fabric (14) operably secured to a strip of more resilient material that is preferably a second fabric (16) such as powermesh or the like. The band is formed by stretching the first fabric and resilient material (16) into a stretched position and operably securing the two materials together with a fastening structure (36). Preferably, the fastening structure is a plurality of space-apart stitching lines (40) that are parrellely aligned with each other and substantially perpendicularly aligned with the longitudinal length (30) of the band.

A sewing machine feed mechanism is mounted on a work table of a sewing machine for transporting fabrics to be sewn, and includes a feed belt defining an encircled space; two belt wheels, on which two opposite ends of the feed belt are mounted; a driving source for driving the two belt wheels and the feed belt to rotate synchronously; a plurality of pressing elements located in the encircled space with respective bottom in contact with the feed belt; and an airbag located atop the pressing elements and connected to an external control device to have adjustable internal pressure. With these arrangements, the sewing machine feed mechanism has simplified structure to allow easy mounting/dismounting and reduced manufacturing cost thereof. Further, fabrics placed between the work table and the feed belt can be evenly pressed while being transported into a stitch forming area of the sewing machine for sewing.

A sewing machine includes: a needle rod (11) being reciprocated vertically; tension discs (4, 5) sandwiching an upper thread; a feed mechanism (26) transporting a sewing object in a vertical direction; a reciprocating mechanism reciprocating the needle rod laterally; an upper thread tension adjusting mechanism adjusting the tension discs; a feed amount adjusting mechanism adjusting a feed amount of the feed mechanism; a stitch width adjusting mechanism adjusting a stitch width of the reciprocating mechanism; and a control apparatus controlling the upper thread tension adjusting mechanism, the feed amount adjusting mechanism, and/or the stitch width adjusting mechanism. A common adjusting mechanism (10), being one of the feed amount adjusting mechanism and the stitch width adjusting mechanism, includes: a motor; an adjusting mechanism body (18) being a tooth-missing gear and/or a cam; and a variation amount adjusting unit. The upper thread tension adjusting mechanism includes: a thread loosening portion (21); and an upper thread tension adjusting unit (10).

The present invention refers to a pre-folding device for tapes used to feed tape edge machines, especially for mattresses, which accepts any size of tapes and includes a support block that guides a sliding frame formed of a central stem and a fork designed to create a semicircle arch-shaped slot, whose linear development can be varied by sliding the frame with a threaded actuation bar.

A sewing machine that suppresses sewing defects is provided. The sewing machine includes: a sewing needing, held by a needle bar and moving back and forth while holding an upper thread; a shuttle, configured to hold a bobbin which is housed in a bobbin case and around which a lower thread is wound, and cooperating with the sewing needle to form a seam; a presser foot member, configured to press a to-be-sewn article at a sewing position directly below the sewing needle; a pressure adjustment portion, adjusting pressure applied to the to-be-sewn article by the presser foot member; a feeding mechanism, where endless feeding belts for feeding the to-be-sewn article from the sewing position to a first direction are disposed on two sides of a second direction orthogonal to a first direction with respect to the sewing position, the feeding mechanism is provided with a belt drive portion, and the belt drive portion independently drives the feeding belts on one side of the second direction with respect to the sewing position and the feeding belts on another side of the second direction with respect to the sewing position; and a control portion, configured to control the pressure adjustment portion to make a pressure of the presser foot member be corresponding to a difference between a feeding amount of the feeding belts on one side of the second direction with respect to the sewing position and a feeding amount of the feeding belts on another side of the second direction with respect to the sewing position.
