    摘要: 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.

    摘要: A portable carpet binding machine comprising a housing defining an interior region, a drive mechanism supported by the housing and at least partially disposed in the interior region, a prime mover operatively coupled to the drive mechanism for providing motive power to the drive mechanism, a sewing assembly driven via the drive mechanism for sewing a strip of material to a piece of carpet. The portable carpet binding machine includes a carpet feeding assembly including a feed driver mechanism and a coacting puller mechanism operating in substantially synchronous movement to linearly feed the piece of carpet relative to the sewing assembly. The feed driver mechanism includes a feed-dog driven via the drive mechanism that intermittently engages the bottom of the piece of carpet to thereby advance the piece of carpet forward. The coacting puller mechanism includes first and second feed rollers driven via the drive mechanism. The first feed roller engages the top of the piece of carpet and the second feed roller engages the bottom of the piece of carpet. The first and second feed rollers pull the piece of carpet forward substantially simultaneously with respect to the advancement by the feed-dog of the feed driver mechanism.

    摘要: A drive means for feeding a material to be sewn on a sewing machine (1) includes a feed dog (7) to be coupled to a continuous rotary drive (9) via at least one intermediate drive. To achieve optimum drive conditions in a comparatively simple way, the intermediate drive consists of a belt drive (10) with a belt (13) circulating around a drive wheel (11) and a driven wheel (12), where the belt (13) having an excess length is guided over a control roller (14) at the working portion thereof (131) and over a tension roller (15) at the return portion (132) thereof, and the control roller (14) and the tension roller (15) are mounted so as to be periodically reciprocated in the sense of a release or deflection of the belt (13) for decelerating, stopping and accelerating the rotation of the driven wheel, and the driven wheel (12) is in rotary connection with a feed dog (7) designed as circular conveyor, in particular as conveyor belt (20).

    摘要: An improved method and apparatus for the assembly of pillow-top mattress covers. In the method of this invention, the gussets for a pillow-top mattress cover are prepared in a single step in which the gusset material is folded longitudinally, and the flange material is attached thereto and the gusset material is sewn together in one stitch. Thereafter, a gusset is attached to each of the top and bottom panels of the cover along its outer edge. Each gusset is secured to the underside of its associated top or bottom panel at the folded edge using a blind stitch which is not visible externally of the panel. No gluing is required. During the step of attaching the gusset to its associated mattress cover panel, precisely positioned mitered corners are formed on the gusset where the gusset is to be attached to the corner of its associated panel. In the apparatus of this invention, a conventional blind stitch machine is modified to accept thicker work by providing a wider cam for urging work into the needle area, top and bottom feed rollers disposed even with the needle, and pneumatic control of the lower support arm.

    摘要: A workpiece puller mechanism for a sewing machine including a carrier including a feed shaft mounted thereon that supports a feed roller. The periphery of the feed roller is biased downwardly into engagement with the upper surface of the workpiece while the lower surface is engaged by the feed dogs. A puller housing is mounted on the sewing machine having a puller shaft rotatably mounted for rotation therein. Rotation of the puller shaft is imparted by a timing belt that overlies sprockets on the sewing machine main drive shaft and the puller shaft. The puller shaft carries a crank head that is connected by a connecting bar assembly to the input member of a one way clutch assembly. The one way clutch assembly provides drive in one direction only to the drive shaft for the feed roller.

    摘要: The start and end timing of fabric feed in a sewing machine greatly affects the tightening of needle thread, that is, the sewing quality. Among the electronically controlled zigzag sewing machines, those equipped with feed means directly driven by a pulse motor supplied with command pulses, it has become possible to control freely the start and end timing of fabric feed. Disclosed is a feed control device for an electronically controlled zigzag sewing machine comprising pulse train generating means for generating feed command pulse train in a predetermined pulse train pattern depending on the number of pulses corresponding to the feed stroke of the work fabric and the speed of the main motor, and pulse train generation control means for controlling the start of operation of the pulse train generating means according to the speed of the main motor so that the vertical motion phase of the needle at the end of generation of the command pulse train by the pulse train generating means may be delayed the more as the speed of the main motor is the faster.

    摘要: A sewing machine has a feed for the workpiece which is to be sewn. A workpiece conveyor performs a skipping feed movement below the workpiece. Above the workpiece a turning device enables the workpiece to be turned about an axis which is coincident with the needle. In order to sew in an edge-parallel manner with an automatic guidance, workpieces made from soft materials with curved or angular seam courses, may be turned responsive to air nozzles directed in acutely-angled manner on to the supporting plate. The air nozzles are arranged tangentially, and in spaced manner, with respect to the needle.
