Abstract: A separator and stacker apparatus and method for separating a completed stack of web product from a stack of product being built thereafter. Preferred embodiments of the present invention utilize a stack building carriage having a forked or slotted floor cooperating with a load finger assembly to discharge the completed product stack from the stack building carriage. The load finger assembly preferably has a set of load fingers which mesh with the carriage floor so that when the load finger assembly is actuated, the load fingers pass substantially unobstructed through the stack building carriage. The load finger assembly and the stack building carriage can therefore pass through their motions independently of one another, permitting the stack building carriage to return to a stack building position without waiting for the load finger assembly to retract.

Abstract: A separator finger apparatus and method for insertion of a separation finger into and removal from a stream of web product. The unique motion provided by the elements making up the separation finger apparatus permits the separation finger to be mounted close to folding rolls (from which the web product issues) with reduced separation finger-to-folding roll interference. Specifically, the separation finger is manipulated to rotate and translate simultaneously as it is inserted into or removed from the stream of web product. The elements creating the separation finger motion are preferably a pivot arm mounted for rotation about a first axis and a translation member mounted for rotation about a second axis. The pivot arm is preferably rotatably coupled to the separation finger at a third axis. The separation finger is preferably coupled to the translation member for translational or sliding motion therealong.
