A method of aligning a stack, method of aligning stacks of a stream of stacks, method of transporting stacks of a stream of stacks, and a stack aligner for aligning stacks of a stream of stacks

摘要

A system (100) for forming and wrapping a plurality of stacks (108) of sheet-like product is provided. The system includes a stack aligner (114) for squaring up leading and trailing ends (126, 128) of the stack as well as sides (130, 132) of the stacks is provided. The stack aligner is also configured for controlling the position of the stacks along the stack travel path (112) such that the stacks exit the stack aligner with tight positional tolerances for being fed to the stack wrapping arrangement (116).
