Improvements in automatic machines for the formation of boxes from flattened simielaborados cardboard or similar material

摘要

A forming assembly for automatic machines for forming boxes from semi-finished flat blanks, comprises a plate support with associated suction means for the semi-finished blanks and a forming mould for the erection of the parts of the semi-finished blank intended to constitute the side walls of the box. The forming mould has simplified longitudinal and transverse forming elements which are adjustable in length, width and height, and the plate support has spring feet supported by modular blocks releasably fixed to the sides of the plate. The plate support also has suction members connectible by a system of external tubing to a vacuum source.
