Abstract (en)
[origin: US4715847A] Blanks (10) for producing folding boxes, etc., are severed from an advancing sheet (11), conveyed continuously, at a constant speed by first drawing rollers specifically by partial severing cuts (cutting lines 33, 34) supplementing one another and made in successive work cycles. The blanks (10) are severed from the sheet (11), with the exception of residual connections (35), and are separated completely from the sheet (11) by tearing as a result of a higher speed of additional drawing roller located downstream of the first rollers.
