Definitions

  • the present invention relates to a device according to the preamble of claim 1.
  • the contact ruler moves along an arc against the band-shaped workpiece to be pressed, so that there is not always a perfect surface contact between the contact ruler 45 and the workpiece 43.
  • the invention seeks to remedy this.
  • the invention as characterized in the claim, solves the problem of creating a device for the gradual advancement of a band-shaped workpiece, in which the contact ruler is arranged between swivel arms which are articulated on the rocker and on a frame part and further via an intermediate support the pivot arms is articulated, which intermediate carrier is in turn pivotally connected to the housing.
  • the advantage achieved by the invention is essentially to be seen in the fact that the pressure ruler can be moved in a straight line and at right angles to the workpiece to be locked, so that when it is locked a surface contact or surface pressure takes place.
  • the aim of the invention is to remedy the disadvantage mentioned.
  • the device according to the invention is characterized by the features of claim 1.
  • the only drawing figure shows an embodiment of the device according to the invention.
  • the pressure ruler 46 has a rectangular or square cross section.
  • the pressure ruler is fixedly connected to an intermediate support 80 or is formed in one piece with it, which intermediate support can be formed from, for example, two parallel support rods.
  • the intermediate carrier 80 is articulated at a pivot point 85 on the pivot arms 13, 14.
  • the intermediate carrier 80 is further articulated on links 81, which in turn are articulated on the housing at a pivot point 82.
  • the respective pivot points are arranged in such a way that the pivot point 82 of the link 81 on the housing is located on a straight line 83 which runs through the axis of rotation of the upper feed roller 3 located in the pressing position and perpendicular to the feed plane of the band-shaped workpiece 43.
