  • Patent number: 6470815
    Abstract: An improved structure high speed zigzag stitch industrial-use sewing machine in which a vertically extending columnar elevated material feed needle plate platform (Post Bed) structure is disposed below the needle holder of the sewing machine. The drive mechanism of the revolving shuttle and the material feed dog plate are situated in the interior section of the elevated material feed needle plate platform, with changes in the type of stitches sewn by the sewing machine governed by a pattern cam. As such, the elevated material feed needle plate platform (Post Bed) structure provides for wider applications than conventional level platform-type material feed needle plates which are incapable of easily sewing across concave, convex, and other irregular contours of objects being processed.

  • Patent number: 6332418
    Abstract: A sewing machine related to the present invention comprises a needle plate and feed dogs. A second feed dog slot provided at the cloth send-in side of a portal shaped needle hole of the needle plate is shifted to the right side from the center of the portal shaped needle hole. The left side first feed dog slot is extending toward the second feed dog slot side in the cloth send-in side of the portal shaped needle hole, so as to be formed a wide breadth portion from side to side. A first cross-piece of the needle plate is disposed between the wide breadth portion and a needle drop portion of the portal shaped needle hole, and a second cross-piece of the needle plate is disposed between the second feed dog slot and said needle drop portion. The first cross-piece is formed wider in the cloth feed direction than the second cross-piece. A differential feed dog disposed in the cloth send-in side of the needle drop portion is composed in a shape combining each feed dog slots.

  • Patent number: 6332415
    Abstract: A sewing machine for sewing large work pieces such as sails or tarps, has a sewing bed with a large trough, the axis of which is perpendicular to the axis of the sewing head support arm. Fabric is held within the trough, either by being folded, bunched or rolled, with fabric being either fed into the trough as stitching progresses, or is drawn out of the trough during stitching. The fabric may be rolled, bunched or folded within the trough. The trough may be selectively covered with a removable cover plate, to provide a flat sewing bed for sewing of smaller pieces of fabric.

  • Patent number: 6244202
    Abstract: The needle plate for the sewing machine supporting the material to be sewn (the fabric) which is pressed by the pressing piece forming the sewing machine, wherein the fabric is sent into the interfacing space between the needle plate and the pressing piece and the support of the receiving plate is elastically turned down, keeping the fabric at intervals allowing for the sending and thus preventing the puckering on the fabric. The fabric guide set on the needle plate for the center sewing is provided on the needle plate where the needle falls and carries out the sewing by regulating the fabric by a determined width of the sewing. The three-fold guide installed on the needle plate for the three-fold sewing is provided on the location where the needle falls, and carries out the sewing by winding the fabric around to make it three-fold.

  • Patent number: 5964171
    Abstract: A method for sewing leather articles includes positioning one edge of a first article (8) and one edge of a second article (9) to be sewn together against respective flat side surfaces (7a,7b) of a longitudinal guiding plate (7) formed at the top of a ring-like block (11). The ring-like block (11) rotates on a pin (12) that is supported, with horizontal axis and perpendicular to said guiding plate (7), by a free end of an arm (13) that swings with respect to a stationary support frame (2). The edges of the articles (8,9) are sewn together by means of an arc-shaped needle (6), which is reciprocated on a plane transversal to the guiding plate (7), between a retracted position, in which the needle is located beside one of said flat side surfaces (7b) and a piercing position, in which the needle pierces said articles (8,9); the needle (6) is moved forward and backward according to a predetermined step.
