  • Another edge clamp which has become known comprises a C-shaped one Clamp body, on the upper and lower side legs one spindle each adjustable in a nut thread is arranged to clamp the jaws against the workpiece press and thus fix the clamp body to the workpiece.
  • a third spindle is provided which is arranged adjustable in the middle part of the clamp body is and serves the edge pressure element in the direction to adjust the edge and thus act on the edge part.
  • An edge clamp is also known from DE-U-88 00 461, in which the clamping jaws fixing the workpiece are spiral are pivotable and have a non-slip surface. These jaws strive to distance due to reduce their spiral shape once with the edge pressure element a pressure on the edge part and thus the workpiece is exercised. A torsion spring guides these jaws into theirs Exit system back.
  • This tool has the disadvantage that it is necessary when starting the Edge clamp to move the jaws so far that they begin To fix the workpiece. Only then is it possible to use the edge pressure element to apply the edge part.
