Abstract
A presetting table for preparing a system of converting tools in a stripping station of a converting press positions the following face to face, in a position simulating centring along the machine axis and positioning at the first rule: the stripper-holder plate of an upper stripping die, a central stripping board and a replica of a pull-out frame carrying telescopic pins. The upper stripping die is prepared by using the central stripping board as a template.
Claims5
A method of preparing a system of converting tools for use in a stripping station in a converting press, wherein the system of converting tools comprises at least one central stripping board having a plurality of apertures passing through the board, and an upper stripping die having a stripper holder plate, the method comprising:
- disposing the central stripping board and the stripper holder plate face to face outside the converting press in a fixed adjustment position;
- fixing strippers to the stripper holder plate for forming the upper stripping die, by fixing respective strippers in line with the apertures in the central stripping board;
- and
- then placing and centering the upper stripping die and the central stripping board in the stripping station, wherein the stripper holder plate and the central stripping board are in the same relative positions, as seen in projection onto a plane parallel to the central stripping board, when they are in the adjustment position as the positions occupied when they are in the stripping station during lateral centering thereof relative to the machine axis and during longitudinal adjustment to a first rule.
