Abstract (en)
[origin: US4757731A] A guillotine type cutting machine wherein the length of cuts to be made in stacks of sheets determines the force with which a hold-down device bears upon a stack in the course of the cutting operation to prevent stray movements of the sheets. The force varies as a function of the length of the contemplated cuts and is regulated in such a way that the pressure of the hold-down device per unit area of a larger or smaller stack containing identical numbers and types of sheets is the same.
