Abstract

Disclosed is an apparatus for producing a sleeve-type printing form from a plate-shaped blank. The apparatus has a fixing device for fixing the uppermost plate-shaped blank of a stack of blanks as a flat raw form, a curving device for curving the flat raw form, and a welding machine by which the plate edges that constitute the beginning and end of the printing form can be welded by a laser beam. The apparatus includes a housing which is a radiation protective casing. The curving device and the welding machine are arranged in the housing, Outside of the housing, there is a layout table, and an opening is left in the housing above the layout table. A fixing frame to hold the plate-shaped blank can be moved between the layout table and the curving device by means of a linear drive, so that the entire production process for the sleeve-type printing form can be performed inside the housing, which can be sealed in a radiation-proof manner during the production process.
