Definitions

  • the invention relates to a method for tailored cutting of strips according to the preamble of claim 1.
  • glass retaining strips hold a glass pane inserted in the frame of a window in their position and consist for example of PVC, wood or aluminum. Depending on the construction of the window, these glass retaining strips are cut to length either at right angles or in miter at their ends and attached to the inner circumference of the window frame.
  • the corresponding dimensions are taken off the window and the glazing beads are cut from the measured dimensions.
  • the removal of the dimensions at the window is done, for example, using non-contact, such as laser-based method.
  • non-contact methods are theoretically very precise, however, these methods easily result in measurement errors that result in the inaccurate positioning or alignment of the required Length measuring devices are justified.
  • length measuring devices have a relatively high purchase price.
  • the known contact methods for example, the removal of the measures by means of telescoping telescoping telescopic tubes provide relatively inaccurate measurement results.
  • the actual measurement result of the length scan is corrected with the value of the deviation and then cut the bar to the correct length.
  • the error compensation method is to be performed only once. In the measurements made in the manufacture of the bars with the scanning device according to the error compensation method, the stored information about the deviation after the length scanning simply needs to be retrieved from the information memory, after which the bar is corrected for the value by the deviation by a separator Length measure can be cut. It should also be noted that the method is by no means limited to the cutting of the strips to clear dimensions between facing inner edges. Rather, the applicability of the method is also to extend to the case in which the strips are cut to defined by two mutually pioneering outer edges outside dimensions of particular doors or windows. The deviation corresponds to the difference between the length dimension of the strip and the actual length dimension between the edges. To store the information about the deviation are basically all conceivable memory in question. Of course, the method is also suitable for cutting other workpieces such as boards, rungs or the like.
