  • Patent number: 7739972
    Abstract: The present invention relates to a simple and inexpensive method for producing a mattress panel or quilt having corners which deviate from an orthogonal pattern. The method renders a material having two stitched seams between two sewn products that are arranged adjacently. The two stitched seams are created by a sewing device, which moves transversely to the conveying direction of the material. The material is cut between said seams by a sewing unit, located within the sewing device. Prior to or during the stitching of the seams, another device removes a sub-area comprising both sewn products, resulting in a mattress panel or quilt with corners deviating from an orthogonal pattern.

  • Patent number: 6592066
    Abstract: A thread guide (33) for traversing and guiding a thread (5) in a rotating winding bobbin (1) for producing a cross-wound bobbin in a bobbin winder of a textile machine by controlling vibrations of the thread guide. The thread guide (33) is permanently and directly connected to at least one energy accumulator (20,21) throughout the entire traversing motion. The potential energy of the energy accumulator (20,21) increases continuously after the dead center of the traversing area. A substantially harmonious oscillating mechanical system is thus formed with the thread guide.

  • Patent number: 6540172
    Abstract: A method for producing cheeses of the random winding type, wherein the workstations of an automatic cheese winder comprise a winding device with a yarn guide drum and a creel, both supported in an axially shiftable relation to each other, the creel holding the cheese in a rotatable manner and the yarn guide drum driving the cheese through frictional engagement, a ribbon disturbance device and an edge displacement device. The ribbon disturbance device causes a slippage by a defined adjustment of the bearing pressure of the cheese on the yarn guide drum. Relative movements between the yarn guide drum and the creel are initiated in the area of ribbon winding zones which counteract a stroke change caused by the ribbon disturbance during the winding of the yarn onto the cheese.

  • Patent number: 6530538
    Abstract: A winding device (24) for a textile machine (1) producing cheeses has a creel (18) for holding a cheese (11) between tube receiving plates (38, 38′), a yarn traversing device (28) comprising a separate drive (31), and a speed-regulatable drive device (27) integrated in the creel (18) to move in a bearing housing (23) of the creel (18) and connected to one of the tube receiving plates (38, 38′). The drive device (27) can be loaded with a braking current which produces a moment opposite the direction of rotation (SR) of the cheese (11), for braking the cheese (11). The drive device (27) is arranged in a sliding sleeve (35) that can be loaded pneumatically against the displacement force of spring elements (43) to move one of the tube receiving plates (38) outwardly as needed in a creel opening direction.

  • Patent number: 6511012
    Abstract: An apparatus for controlling the tension of a traveling yarn includes a rake tensioner having stationary and displaceable yarn tensioning elements in engagement with the traveling yarn, and an electrical coil to which electrical current is supplied by a regulating device. The displaceable yam tensioning elements and the electrical coil are disposed on a common pivot lever. The electrical coil is pivotable in an air gap through which magnetic field lines pass. The tension of the traveling yarn is controlled as a function of the current supplied to the electrical coil. The present invention, thusly, improves the control of the tension of the traveling yarn in spinning or bobbin winding machines.

  • Patent number: 6405967
    Abstract: A device for pivoting a creel of a textile machine, which holds a bobbin in contact with a roller during the winding process. The creel (2) is fastened on a shaft (5) defining a pivot axis. A lifting device (9) connected with the creel (2) has a lever (10) fixed with the shaft (5) against relative rotation. An arresting element (12) seated on the shaft (5) can be alternatingly coupled to the shaft (5) or a fixed holding element (21). When the arresting element (12) is coupled with the shaft (5), potential energy is stored in an energy storage device, which is released when the connection changes from the shaft (5) to the holding element (21), whereby the lever (10) and the shaft (5) are abruptly moved toward the arresting element (12). The device makes it possible to break the contact between the cheese (1) and the drive roller (3) quickly and dependably in case of a power failure. Interference with grasping an upper yarn end, as well as damage to the yarn and yarn positioning errors, can be avoided.
