MOVABLE UPPER TOOL FOR THE SEPARATION OF THE BLANKS FROM A SHEET WHICH IS PROCESSED BY A PRESS THAT MANUFACTURES PACKAGES

摘要

The movable upper tool for the separation of the blanks in a package manufacturing press comprises a base plate with apertures, and on the lower side of which base plate punches are fitted. The tool cooperates with a lower tool for the separation of the blanks. The apertures are arranged along two orthogonal axes. One of these orthogonal axes consists of a line slanted with regard to one of the edges of the base plate of the movable upper tool. At least one of the lateral sides of the base section of the punches is tangential to one of the apertures so that the space between the punches determines a total pressure identical of the latter on the blank to be separated, in the neighbourhood of a separating bar of the lower tool for the separation of the blanks irrespective of the position occupied by the separating bar of the lower tool.
