Abstract

An apparatus for producing a sleeve-shaped printing form from a plate-shaped blank includes a circular shaping device for the blank, a welding system, by means of which the plate edges forming the start and end of the printing form can be cut to size, maintaining their dimensions, and welded, and a displaceable device for picking up and for transporting the blank to the circular shaping device. The displaceable device has a fixing frame which has two lifting elements which can be adjusted in accordance with the distance between the plate edges to be joined and can be set along the respective plate edge. The leading plate edge is equipped with a register hole system, a lifting element comprising a pin register interacting with the register hole system while suction elements fix the leading edge, the other lifting element is configured with at least one suction element, the feed table being arranged so as to rise in the direction of the welding system, so that the blank, fixed by means of the pin register, aligns itself in an in-register and level manner, in the direction of its trailing edge, along the obliquely extending feed table on account of its inherent weight.
