    摘要: The invention relates to rotary punch, particularly a rotary punch comprising a foil cutter for use on the lateral surface of a carrier roll, wherein the foil cutter comprises a base plate having an underside and a top side, wherein at least one blade is disposed on the top side of the base plate, and wherein the top side of the base plate comprises at least one region that adjoins blades and is partially or completely surrounded by blades, in which region parts of the flat stock to be punched can become jammed during punching. According to the invention, the foil cutter, in the at least one region that adjoins blades and is partially or completely surrounded by blades, comprises at least one elevation disposed on the top side of the base plate, which elevation is disposed, designed and connected to the foil cutter such that it prevents jamming of the punched flat stock or partial regions of the punched flat stock.
