  • the machining tool is guided along the line of the double arrow i-j for cutting, for example in the direction i, and then returned again in the direction j.
  • the pivot pins 3 and 4 or the axes of rotation I, II are arranged at right angles with respect to the support plane of the worktable 1. This ensures excellent guidance of the stop rail 5 on the workbench 1.
  • certain fixing means are provided on the axes of rotation I, II or on the guide carriage 31, 41 in order to fix the stop rail 5 in the desired position.
  • Fig. 4 is a further embodiment of the invention shown schematically in three different positions B 1 , B 2 and B 3 .
  • the arrangement shown here corresponds to the in Fig. 3a , so do not repeat all elements here.
  • the guideway 7 in two subregions 7, 7 'divided. Make it up guideway pockets.
  • the arrangement shown here results in that no separate measuring device for the relative position of the guide carriage 31 to the stop rail 5 is necessary.
  • the right part which is oriented closer to the cutting line S, located on the end of the cutting line S end stop 51. This causes the guide carriage 31 in a movement of the stop rail. 5 to the right only up to this length stop stop 51 can get.
  • the position of the length stop stop 51 can be stored, for example, as a machine constant.
  • precisely this position of the longitudinal stop stop 51 with the contact switch 52 is variable in the longitudinal direction of the stop rail 5 and thus realizes a very simple measuring system.
  • the individual locking points are then interrogated again with micro-switches, this information is then processed again by the controller.
  • the stop rail 5 is set in the position set in B 1 . This means that the stop rail 5 is both with respect to the pivot pin 4 as well as with respect to Pivot bolt 3 locked. If you now open the lock of the located closer to the section line S pivot pin 3 and pivots the stop bar 5 by the angle ⁇ , one arrives at the position B 2nd It should be noted that the relative position of the rear pivot pin 4 and the guide carriage 41 on the stop bar 5 is unchanged. Due to the pivoting movement by the angle ⁇ , the front end 72 of the stop bar 5 moves away from the cutting line S, the problem known from the prior art arises.
  • the machine control is informed that the stop rail 5 is in the correct position to transmit appropriate dimensions (correction measure) or to allow processing in principle.
