DEVICE FOR TAKING OVER AND TRANSFERRING FOLDED SHEETS FROM A CONVEYOR

摘要

Intermediate or end products comprising a plurality of interstuffed and overlapping folded printed signatures or sheets are straddlingly fed or conveyed by a plurality of collating conveyors of a circulatingly driven collating cylinder or drum to a product transfer location or pick-up region. At the product pick-up region the intermediate or end products are picked-up or taken-over by a product withdrawal conveyor or device. The product withdrawal conveyor comprises holding or gripping mechanisms which are mounted in spaced relationship on a traction member. These holding mechanisms comprise pivotable clamping mechanisms which are laterally pivotable into a location between the halves or portions of the folded products. These halves or portions are raised or separated from each other. These clamping mechanisms press and thus clamp the intermediate or end products against a counter-element. A complete closure of the intermediate or end products is thus prevented by the clamping mechanisms inserted between the product halves or portions. The product halves or portions are spread apart by pivoting the clamping mechanisms together with the counter-elements about a pivot axis. This product spreading action allows transfer of the intermediate or end products while in an open condition to a further collating cylinder or similar apparatus.
