Abstract (en)
[origin: ES8502941A1] An apparatus which produces a precisely shaped and positioned perforated line in a blank for a parallelepipedic package has a blade and a roller for pressing the blank against the blade. The blade is stationary relative to the packaging blank and provides a perforated line which does not penetrate the inner layer of the packaging material. The roller is mounted on a connecting bar which is linked to a reciprocating drive. The roller moves in a guide which positions the roller relative to the blade during each stroke of the reciprocating drive.
