Definitions

  • the invention relates to a device for thread-appropriate separation of a section of a fabric, with a stationary holding device from a table with associated clamps for the edge of the fabric to be separated and with a driven carriage with at least one abutment for tearing the fabric and for guiding the separated Edges on the one hand of the section and on the other hand of the rest of the fabric.
  • a generic device is also described in GB-PS 93 58 (A.D. 1915).
  • a small incision is made in the fabric with a knife. After pulling back the knife, the fabric is torn open with an abutment, which is slid along the torn edges of the fabric.
  • threads that extend in the direction of the tear edge can also be separated.
  • the object of the invention is to improve a device of the type described in the opening paragraph in such a way that the separation takes place according to the thread.
  • rollers arranged next to one another as abutments, the rollers being designed as double-tapered rollers (diabolo rollers), the smallest cross sections of which are aligned with the table surface.
  • the carriage is preferably guided on a path that extends essentially perpendicular to the connecting line of the two clamps.
  • the clamps can have clamping jaws, one clamping jaw each being formed by a tab extending over the table surface and the other clamping jaw being formed by a movable plunger mounted in the table below the tab.
  • the fabric can thus be spread out and smoothed out on the table.
  • the movable plunger is outside the area covered by the fabric to be divided.
  • the movable plunger is expediently arranged at the end of a piston rod of a pneumatically or hydraulically actuated lifting cylinder which is actuated when the fabric web is inserted between the two clamping jaws. When the lifting cylinder or cylinders are actuated, the edge of the fabric web is fixed.
  • the device shown consists in its basic structure of a box-shaped table 1, the upper wall 2 of which has a slot 3 extending over the entire length of the table. At one end of the table and on both sides of the slot 3, tabs 4, 5 are attached to the top of the table, the ends of which protrude in the direction of the slot 3 define an insertion gap with the top of the table 1. Under the projecting ends of the tabs 4, 5 there are openings in the upper wall 2 of the table 1, in which movable plungers 7, 8 are arranged. The plungers sit at the ends of piston rods 9, 10 of pneumatically actuated lifting cylinders 11, 12, which are fastened to the bottom 13 of the box-shaped table. Accordingly, the plungers 7, 8 can be moved against the projecting ends of the tabs 4, 5 when the lifting cylinders 11, 12 are actuated. The protruding ends of the tabs 4, 5 and the plungers 7, 8 thus form jaws of clamps.
  • a further lifting cylinder 14 is attached to the bottom 13 of the table 1, which extends over the entire length of the table 1 and which serves as a guide and drive for a carriage 15 which can be moved along the slot 3.
  • the carriage 15 carries on its top two rollers 16, 17 which are designed as double tapered rollers (diabolo rollers).
  • the rollers 16, 17 are arranged so that the connecting line of their axes extends perpendicular to the direction of the slot 3 and that their smallest cross sections are arranged approximately at the level of the table surface. Otherwise, the rollers 16, 17 are freely rotatable on the carriage 15.
  • the lifting cylinders 11, 12 and 14 can be controlled in a suitable manner.
  • a control device is not shown.
