  • Patent number: 11111615
    Abstract: Apparatuses, methods, and computer program products for quilting webs without compressing the webs. A quilting machine includes a needle bar to which needles are attached, needle thread passing through each needle, a looper shaft to which loopers are attached, a looper corresponding to each needle and from which looper thread is provided to form stitches, and a retainer bar to which spreaders are attached to facilitate stitching. A drive pulley powered by a first servo motor rotates cranks to move the needles through a cycle and rotates a belt which rotates an indexer pulley. Rotation of the indexer pulley oscillates the looper shaft and reciprocates the retainer bar. Another drive pulley powered by a second servo motor operates to move an input web through the machine between chain stitches.

  • Patent number: 8997671
    Abstract: A set of sewing disks for controlling the movement of a piece of fabric over the free arm and under the needle of a sewing or quilting machine. Each disk is flat and has an oval or circular configuration and comprises three registered, stacked adhesively attached layers—a first contact layer made of open cell foam, a semi-rigid intermediate stiffener member, and a second contact layer made of closed cell foam. When each disk is placed over a piece of fabric with the lower contact layer is placed adjacent thereto, the individual's fingers are exposed at all times and placed over the opposite contact layer. The intermediate stiffener layer spreads and evenly dissipates the forces exerted by the fingers to the top contact layer to the lower contact layer. Because the finger tips are not in contact with the fabric, soiling of the fabric by the finger tips is prevented.

A leading edge clamp is preattached along the leading edge of a panel and the clamp is fed from an operator station to the upstream end of a shuttle movably mounted on the frame of a programmed single needle quilting machine. Opposed belt conveyors on opposite sides of the shuttle advance the clamp and pull the panel onto the shuttle, with the belts gripping the side edges of the panel as it is pulled. A trailing edge clamp bar frictionally engages the panel to provide trailing edge securement to the panel, with the belts and leading edge clamp providing securement around the other edges to stretch the panel on the shuttle. The shuttle reciprocates longitudinally under a sewing head that moves transversely on the frame at a quilting station, while the sewing head operates to stitch a pattern in the panel.

    Abstract: A quilting machine includes a multiple needle quilter with a panel cutter located in-line therewith and downstream thereof and having an accumulator therebetween. A programmable controller operates the quilter to stitch a programmed series of one or more patterns on a web. A feed roller angular encoder measures the quilted web length fed under tension to the accumulator. A detector signals when the accumulator is full, whereupon the controller causes web to be fed from the accumulator to the panel cutter, where it passes without tension thereon toward a photo sensor. The photo sensor signals the controller which activates the cutter to sever a predetermined panel length from the web. The controller then reads information from the encoder and the accumulator detector to determine the amount of stressed quilt required to replenish the cutoff panel length.

    Abstract: In a quilting machine for quilting or stitching textile formations of cover-material webs and filler-material webs, the material webs to be stitched together are loosely withdrawn from stock rollers and sewn together along lengthwise edges or marginal portions of the material webs prior to entering a tenter device. Sewing the lengthwise edges or marginal portions includes simultaneously sewing on respective bands or ribbons which laterally extend beyond a workpiece to be quilted and serve for holding or accommodating the latter in the tenter device. It is thus possible to substantially provide the entire width of the cover-material webs and filler-material webs with a quilt pattern. In this manner, the length of waste cuttings of expensive cover material is substantially reduced.

The lower carriage rides on track rails on the floor running in one direction, and the upper carriage rides on track rails on the lower carriage running in transverse direction. A drive unit is mounted on the upper carriage and has a drive wheel engaging the floor. The drive is produced by running the drive wheel, and rotating the drive unit about a vertical axis, to trace out a pre-designed pattern. The drive wheel can be driven forward, stopped, and reversed. The drive wheel is driven a constant speed, and different kinds of elements of the pattern are produced by turning the drive unit a lesser or greater amount about its vertical axis. A computer unit is utilized, and instructions entered thereinto to turn the drive unit about its vertical axis at predetermined points.

  • Patent number: 4501208
    Abstract: In a quilting machine two or more series of stitches are applied to the product, the product to which stitches have already been applied being moved forward and/or backward, even over a considerable distance, while the exact superposition of the fabrics is maintained.One embodiment of the machine comprises cylindrical containers (10, 11), in which are disposed the rolls (8, 9) of fabric (2, 3) which are to be quilted. During the backward rotation the cloth is wound over the constant diameter of these containers and in this way the tension applied is also constant.In another embodiment, return or loose rollers (160, 170) are provided, which take up a portion of fabric (102, 103) already unwound.The process also permits continuous embroidery, even very complicated embroidery.

  • Patent number: 4254718
    Abstract: A tufting method and apparatus for tufting yarn to a backing layer, including individual tufting elements, comprising, means to control forward and lateral displacement of successive needle strokes. A preferred embodiment includes means to select particular yarns for tufting from a plurality of yarns and means to select the length of yarn to be tufted. In a further preferred embodiment a reduced number of tufting elements is contemplated with the elements spaced so as to enable the production of a full sized tufted product by lateral shifting of the backing layer to provide for intermediate tufting positions.

  • Patent number: 4125079
    Abstract: A bag for forming into a quilted article is produced by pleating two sections of material and by feeding pairs of the folded edges thus formed through respective work stations, each pair comprising one edge from each section and the two edges from each pair being fed side by side and simultaneously through the respective station. At each station, the longitudinal edges of a respective strip of flexible material are simultaneously secured to the respective pair of folded edges so as to produce elongate quilting pockets. Apparatus for producing the bag has a plurality of the work stations, means for folding the sections of material, guides which receive the material from the folding means and feed means which co-operate with the guides to feed the folded edges of each pair side by side and simultaneously to the respective work station. The feed means also serve to draw the strips of flexible material from supports for these strips and through the respective work stations.

  • Patent number: 4061096
    Abstract: Elongated quilted webs which have line out flaws are moved from a first container at high speed in a downward direction in front of an operator, then laterally through a sewing station toward the operator, then downwardly away from the operator to a second container. When a flaw in the web is detected by the operator as the web moves at inspection speed in a downward direction toward the sewing station, the operator allows the flaw to move through the sewing station and then stops the movement of the web. The operator then reverses the direction of movement of the web so that the flaw moves back through the sewing station at sewing speed where one of several sewing machines which is closest to the flaw is energized at the sewing station and operates concurrently with the movement of the web to sew through the web.
