ABSTRACT:
A device for producing work-pieces, in particular foil blanks perforated by means of electron beams, for example for shoe upper parts, with an electron beam work chamber which can be evacuated, input and output appliances placed outside the work chamber for the input of unperforated work-pieces or the output of perforated work-pieces, and a transport appliance with a transport track extending between the input and output appliance and the work chamber across air locks for the controlled transport of work-piece carriers, to which the work-pieces can be applied in predetermined positions, wherein in a given work area within the work chamber a work-piece carrier which forms an element of a series of work-piece carriers lying in the transport track can be moved in at least one work track lying outside the positions of the adjacent work-pieces in the series, relative to a beam source that the work-piece can be perforated at several points by means of the beam source.
