Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
171 words
An apparatus for separating and evacuating sheet products to produce formed packs by stacking from below, the sheet products being squared by reciprocating pallets and evacuated on to a conveyor belt, comprising a set of horizontal separating strips, an assembly of articulated levers supporting said strips and moving said strips beneath the lower portion of a pack in course of formation for free vertical movement of said strips and of the formed pack; means for moving said levers and for moving said separating strips; an evacuating pusher, vertical bars for said pusher each disposed above one of said separating strips; means for moving said pusher; and a sheet-counting device first actuating said means for moving said levers and said separating strips, inserting said strips beneath a predetermined number of sheet products in the formed pack and then actuating said means for moving said pusher when said strips engage said bars, said strips remaining between the formed pack and the top sheet of the next pack during evacuation of the formed pack.
