Document shredder for itemized shredding sets sheet stack on surface centrally slotted to drop sheet to spreader unit below aided by progressive stack pressure from above

摘要

Pressure elements (15) between setdown (4) and closer (11) press the stack (7) onto the surface (4). Each element (15) forms a couple composed of a rocker joined via lifter (20) and control rod (23) to the bearing base (10) to link it to the respective closer (11) so as to swivel this into open or closed settings when entrained by the rocker couple. Each pressure element has an end collar part (29) sloping down towards setdown or stack depending on stack thickness, the collar angle (32) depending on stack thickness or setdown distance. The sheet stack (7) setdown surface (4) has a center slot (5) for itemized sheet withdrawal and its feed to the cutting unit. Both sides of its slot the receiver space (9) is flanked by a closer (11) swivel bearing (10) with the closer (11) closing off space (9) from above during shredding and in the form of half lids round axes (12) between receiver open and closed settings.
