  • Patent number: 10906189
    Abstract: Due to rapid advancement in computing technology of both hardware and software, the labor intensive sewing process has been transformed into a technology-intensive automated process. During an automated process, processing of a work piece can be visually monitored using a sensor system. Data gathered from the sensor system can be used to infer the condition and/or position of the work piece in the work area using, e.g., models of a sensor profile. Evaluation can be carried out before processing begins, during processing and/or after processing of the work piece. Examples of systems and methods are described that provide for initially and successively matching the model of the expected shape for a product work piece to a set of sensor readings of the work piece in order to determine the position of the work piece and support a variety of useful features.

  • Patent number: 5383418
    Abstract: A synchronized, indexed positive material top feeding system for use with sewing and other applications. For example, material being fed to and through the sewing area of a sewing machine, is constantly "gripped" at the top thereof in front of, behind and in the sewing area as well as through an adjustable presser bar. This process takes place without affecting machine speeds, and in feeding movement that is synchronized with the machine feed dog for similar or variable stitch travel. This process is facilitated by a belt with "teeth" that contact and provide frictional engagement of the top of the material.

  • Patent number: 5367968
    Abstract: Apparatus and a concomitant method for sewing seams in upholstered furniture such as mattresses. The apparatus contains a sewing machine located adjacent a conveyor belt which moves the mattress in a linear direction beneath the sewing machine, a presser arm for turning the mattress, and a fastening cylinder for temporarily attaching the mattress to the presser arm during the turning process. A single motor drives the sewing machine, the conveyor belt and the presser arm. As the mattress is moved by the conveyor belt at a first speed, the sewing machine sews a linear portion of a seam in the mattress. A sensor indicates when a corner of the mattress approaches the sewing machine. When the sensor indicates the approach of the corner, the conveyor belt is halted and the motor changes to a slower speed such that the sewing speed is slowed. Simultaneously, the fastening cylinder temporarily attaches a presser arm to the mattress.

  • Patent number: 5361961
    Abstract: A feeding device of a wide sewing material comprises a first belt conveyer unit provided on a supporting member vertically driven by a first elevating unit, a first base plate vertically driven by a second elevating unit provided on the supporting member, a horizontally driving unit for horizontally driving a second base plate and a second belt conveyer unit which is supported by the second base plate and is arranged on the side of the edge portion to be sewn of the wide sewing material in parallel therewith and which is driven to rotate by a rotary device. Since the feeding device can secure a large space from the edge portion by retracting the second belt conveyer units, next operation can be performed with ease. As a result, it is possible to perform the feeding and sewing of a wide sewing material, which is difficult to work at the edge portion thereof automatically, with accuracy and efficiency.

  • Patent number: 5257591
    Abstract: An automatic sewing apparatus for hemming and closing a sleeve is used for hemming a sleeve blank and sewing it into tubular form for making, for example, a short-sleeved T-shirt. The steps subsequent to putting the sleeve blank on a conveyor are done fully automatically and continuously to make the tubular sleeve. The apparatus according to one embodiment of the invention comprises first and second sewing machines disposed at inner corner sides of an L-shaped sewing table, a feed device having a conveying surface disposed on a table part of the first sewing machine side of the sewing table, a folding member for folding the blank edge along the feed direction, a deflecting device having a member for stopping the running of the front end of the hemmed piece above the conveying surface, and a transfer device for feeding the deflected piece of a hemmed sleeve blank to the second sewing machine.

  • Patent number: 5249540
    Abstract: A sewing-material feeding device for a sewing machine has an upper material feeder and a lower material feeder which coact for feeding the sewing material, the lower material feeder being adjacent to the throat plate. The needle passes downward through an extension associated with the upper material feeder, the extension defining a downward-facing resting surface, the resting surface obstructing upward movement of said sewing material and thereby reducing fluttering of the sewing material as the needle is pulled upward and out of the sewing material. A tongue adjacent the throat plate is urged upward and against a portion of the upper material feeder so as to further reduce fluttering of the sewing material as the needle is pulled upward and out of the sewing material. The tongue has a throat hole for receiving the needle when it pierces the sewing material and passes into the throat plate.

  • Patent number: 5226378
    Abstract: An automatic sewing apparatus for hemming and closing a sleeve is used for making a tubular sleeve a short-sleeved T-shirt. After placing the sleeve blanks on a conveyor only, subsequent operations are done fully automatically and continuously to make tubular sleeves, resulting in labor savings, productivity enhancement, and a reduction in savings production cost. In particular two types of shapes cut for sleeves can be sewn by using the apparatus by turning them in the appropriate direction. The apparatus comprises a first sewing machine for hemming and a second sewing machine for edge sewing disposed at both inner corner sides of an L-shaped sewing table, a blank feed device installed at a table part of the first sewing machine side, a folding member for the blank edge, a hemmed piece deflecting device, and direction turning members for turning the deflected piece.

  • Patent number: 5152235
    Abstract: A sewing apparatus for forming cuffs for sweat jackets or anklets for sweat pants or the like. The apparatus includes a movable table carrying an end of an elastic tape continuous to a supply source. The tape advances on a carrying table to a cutting device where the tape is cut. The front end of the tape is transferred to gripping blades which can be inverted, simultaneously with the return movement of the movable table. The tape is further let out toward the gripping blades by a predetermined length feeding device and the gripping blades turn so that the tape front end is folded back on the tape rear part. The tape rear part is cut off and the folded cut-piece is supplied to a sewing machine by a conveying device automatically and sewn to join both ends along the cut line.

  • Patent number: 5136956
    Abstract: A seam forming device is provided for a blindstitching machine for starting a seam at the fabric end. This device has a fabric feeding apparatus positioned direct in front of a feed dog, so as to enable it to form seams which begin at the fabric end at which sewing is initiated. This eliminates the unseamed portion at the fabric end at which sewing is initiated, which has previously been inevitable when sewing with a conventional blindstitching machine. Thus, with the present invention, it is no longer necessary to manually finish the seam after blindstitching.
