Abstract: A parts transfer apparatus for progressively advancing workpieces through successive work stations. A frame is movably mounted within a surrounding, rigid, support structure. Workpiece engaging devices are mounted on the frame for engaging a workpiece in each work station. Pairs of cams are fixedly mounted on the support structure and disposed on opposite sides of the frame to define a reciprocal path of movement for the frame. Cam followers mounted on the frame engage and move along the pairs of cams. A drive mechanism, preferably in the form of opposed acting fluid cylinders, is coupled between the support structure and the frame for reciprocatingly driving the frame between the first and second ends of the support structure.

Abstract: A stop assembly allowing a body to pass over it in a forward direction but obstructing passage in the opposite backward direction. The rollout stop assembly (10) includes a frame (18) and a pair of stops (20) mounted therein. Each stop includes a camming surface (30) which causes the stop to rotate downwardly into the frame upon engagement by the forward moving body (16), thereby allowing passage. Each stop also includes an abutment surface (32) engagable with the passed body that prevents backward movement of the body.

Abstract: A stacking apparatus includes a stacking unit and a bundling unit arranged under the stacking unit. Located at the end of a prestacking space, as seen in the direction (F), is a limiting element which serves as a stop for the folds of the printing products. While the printing products fed, with their fold forward, in the feed direction (F) are being deposited on one another to form a prestack, they are supported approximately centrally by a supporting element in their edge region located opposite the fold. For depositing the prestack so formed into a rest table, supporting arms are pivoted into a position of rest and slide plates are moved out of the region of the stacking space. A residual bend of the printing products is thus preserved in their edge region, thereby improving the stability of the stack.
