  • Patent number: 11464267
    Abstract: A device (40) and a method is described for handling fragments (10) of a broken needle (11), for example in the context of a needle exchange of a broken needle (11) for a new needle (17). The fragments (10) of the broken needle (11) are arranged in a container (16) in a predetermined position. An image (32) of the fragments (10) of the broken needle (11) is then recorded with the aid of a camera (23). The recorded image (32) is stored for documentation (32) at at least one storage location and/or analysed as to whether all the fragments (10) of the broken needle (11) are present. After recording the image (32), the container (16) is closed in order to avoid the fragments (10) of the needle (11) being lost away from the sewing workstation.

    Abstract: A fastener attached product is structured such that a slide fastener is sewn to right and left attached bodies which are bent in a U-shape, and the right and left attached bodies are arranged in a tape surface side to which the element rows of the fastener tape are sewn. Further, the right and left attached bodies come into contact with the outer surfaces of right and left flanges which are arranged in a slider, and the element rows are arranged and exposed between the right and left attached bodies. As a result of this configuration, since the fastener tape is invisible from the outside by the attached body, exposing the element rows can provide the fastener attached product with different design from conventional products and eliminate problems due to degradation in the appearance and design which is caused by the exposure of the fastener tapes.

  • Patent number: 6745711
    Abstract: A pressure foot for minimizing puckering or bunching of biasing fabric and a cloth item, garment or quilt when being sewn or finished. The pressure foot includes a laterally displaced inner foot displaced from the inner feed dog of the sewing machine and a bias guide between the inner and outer feet. The pressure foot is adapted to be used alone or in combination with a bias binder sewing aid that automatically folds the biasing fabric. The pressure foot and bias binder sewing aid form a kit for sewing biasing fabric to an unfinished edge of a cloth item, garment, quilt or the like.

  • Patent number: 6736077
    Abstract: A presser foot assembly is disclosed which is operable to adjust the pressure applied to a fabric by a presser foot in a stitching machine. The presser foot assembly includes an adjustment element, a linkage and a presser foot. A connecting end of the presser foot is connected to the linkage. The adjustment element is operable to be adjusted while the stitching machine is operating, and adjusts the linkage such that the travel distance of a foot end of the presser foot changes. The adjustment element can include an adjustment eccentric, which adjusts the location of a cam. The linkage can include a cam follower, the height of a second end of which is changed when the cam is adjusted. The connecting end of the presser foot engages with the second end of the cam follower, and thus the height of the foot end is adjusted, allowing for more or less pressure to be applied to the fabric.

  • Patent number: 6725795
    Abstract: An improved sewing machine is disclosed for making consistent edge seams. The improvement automatically adjusts a width of a sewn seam based upon feedback from a sensor which detects a position of a sewn edge. Feedback from the sensor causes a transverse adjustment in the position of an edge guide. An outside foot of the sewing machine may be suspended on a biased linkage to permit its transverse displacement when making an adjustment to a seam width.

  • Patent number: 6443080
    Abstract: Provided is a presser foot system for sewing machine comprising a small tubular cylinder bed which is used, for example, in joining crotch sewing of underpants or drawers and joining shoulder sewing of shirts. Distance from the center of a needle location to the cutting starting position of a knife trimming mechanism, wherein the upper edges of the ends of fabrics in a vertical face-to-face contact to be fed to a guide path are cut to an even length, is set to the range of 16.5 mm to 18.0 mm in actual dimension. This range is sufficient so that the ends thus cut by one operation of the knife trimming mechanism are stacked one on another by the operation of guide of upper and lower guides until these reach the needle location. Thus, irrespective of the thickness and flexibility of the fabric material and the presence or absence of a step, the ends of the fabrics cut to the even length can be fed in a predetermined stacked state to the needle location, thereby ensuring high quality finish of sewing.

  • Patent number: 6431098
    Abstract: A thick fabric of poor surface smoothness, such as a fabric for wet suit, can be fed reliably, smoothly and uniformly to perform sewing of excellent finish, without requiring any oil application to the fabric surface before sewing, by arranging a presser foot body, a small presser foot and a roller as follows. The presser foot body is fixedly supported to a lower end portion of a presser bar supported to a sewing arm part so that it is free to move vertically and reciprocally. The small presser foot resiliently pressing the fabric to the upper surface side of a throat plate is disposed on the downstream side than a needle location hole of the presser foot body in the sewing direction. The roller is disposed on the upstream side than the needle location hole in the sewing direction and is rotatable such that its contact portion with the fabric is successively changed with the fabric feed.
