  • Patent number: 4074640
    Abstract: An automatic sewing machine includes a sewing machine mechanism having a seam forming mechanism and a fabric feed mechanism. A detector member senses the position of each free side edge of two layers of fabric to be fed to the seam forming mechanism and generates signals. A pair of manipulators capable of engaging each layer of fabric individually move such each layer of fabric to a predetermined position in response to signals from the detector members. The free side edges of layers of fabric are automatically stitched together by a predetermined distance along the free side edges with the edges maintained in alignment with each other.

  • Patent number: 4044698
    Abstract: Apparatus for joining together two plies of material such as textile fabric comprising a sewing machine, contour guide means for shifting the plies as they are fed forward through the sewing machine to effect contour seaming of the plies, and a feed control clamp for clamping the trailing ends of the plies as they are fed forward. This clamp, clamped on the trailing ends of the plies, moves forward with the plies as they are fed forward. It is also automatically shifted from side to side as it moves forward to maintain the edge of the plies being sewn aligned with the contour guide means. The apparatus further comprises loading means which is adapted, while a pair of plies is being sewn, to receive the next pair to be sewn and, upon completion of sewing the first pair, to enter the next pair in the sewing machine and in the feed control clamp.

  • Patent number: 4036155
    Abstract: An apparatus for guiding work past a sewing machine needle along a predetermined path to form a line of stitching corresponding to the path with deviations of the work from a normal feed path to the needle being sensed and causing a pivotal movement of the work about the needle to overcome the deviation. The ability of the apparatus to correct the deviation is related to the speed of sewing and to maintain this sewing speed within the deviation correcting ability there are fast and slow sewing speeds and sensing means that senses the occurrence of a large deviation and decreases the sewing speed to the slow speed to enable the apparatus to correct the deviation. For sewing a line of stitching a preselected distance from the edge of a workpiece, the vertical axis on which the work is pivoted is slightly tilted so that the workpiece is positioned to have the portion of its edge at the needle normally extend transversely beyond the needle a distance greater than the preselected distance from the needle.

  • Patent number: 4024825
    Abstract: Apparatus as for use on a sewing machine, employing a stock pivoting and advancing platform for directionally guiding while advancing stock relative to a reference point during performance of an operation on said stock, the operation being therefore in a controlled pattern. Normally, a working tool such as a stitching needle, is at the reference point. The stock is incrementally advanced while repeatedly and incrementally being pivoted by the special platform in response to sensing of the pattern such as an edge of the stock. In use on a sewing machine, both the advancement and the pivoting are conducted while the stitching needle penetrates the material.

    Abstract: Apparatus for automatically controlling movement of an area of material with respect to a work point in a machine in which revolvable control means continuously engages the region of the material in front of the work point and in close proximity to that point. An exemplification of the invention is in a sewing machine in which pressure exerting means urges revolvable control means into guiding engagement with that front region in the fabric as the material advances over the support toward the work point, for guiding and smoothing the fabric material and enabling a wide variety of stretchable as well as stiff fabrics to be guided quickly, accurately and effectively.

  • Patent number: 4013026
    Abstract: A sewing machine feeder system includes a fluid powered clamp assembly which applies tension to the plies of material being pulled into the needle of a sewing machine by the feed dogs, with more tension being applied to the lower ply of material. The effective point of application of the tension to the plies of material is offset to the left from the line of pull of the feed dogs which causes the plies of material to tend to turn in a counterclockwise direction into a vertical guide, and the plies of material are maintained in a flat and unwrinkled configuration against the vertical guide so that the plies of material hold themselves properly aligned from the guide to the needle of the sewing machine.

  • Patent number: 3986467
    Abstract: A guiding, stitching and delivering system continuously constrains a piece of material while it guides that piece of material beneath the needle of a sewing machine during the stitching of that piece of material, while that piece of material is stationary during the period of time between the completion of the stitching of that piece of material and the start of the stitching of the next-succeeding piece of material, while the stitches between the trailing edge of that piece of material and the leading edge of that next-succeeding piece of material are being cut, and while that piece of material is being moved to a delivery area. That guiding, stitching and delivering system obviates the formation of needless stitches, places all stitches in the desired locations, and provides certain and easy cutting of the stitches between the trailing edge of that piece of material and the leading edge of that next-succeeding piece of material.

  • Patent number: 3970017
    Abstract: This invention relates to automatic mechanism for processing the edges of pile type fabrics and the like from which thinner or non-pile margins are to be removed. Fabric edge finishing machines are provided with a means for sensing relative thickness of work piece portions, such as terry material as distinguished from thinner or marginal non-terry portions. Accordingly washcloths and the like, as directed by an edge guide and corner turning mechanism, are under the control of a sensor and are automatically guided through the operating localities of instrumentalities, such as the needle and trimming mechanism of an overedge stitcher, or other edge treating machines, to provide for removal of the non-terry material and processing directly along the edge of the remaining terry material.
