PACK ALIGNMENT APPARATUS AND METHODS USING LINEAR MOTOR

摘要

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

1. A method of aligning a stack of a plurality of vertically stacked sheet-like products as the stack travels along a travel path as the stack travels through a stack aligner along the travel path, the stack having a downstream leading end, an upstream trailing end, a pair of sides extending between the leading end and the trailing end, a top and a bottom, the method comprising:
feeding the stack to the stack aligner, pressing the stack between a first paddle of the stack aligner that is downstream from the stack and a second paddle of the stack aligner that is upstream from the stack so as to substantially align all of the sheet-like product such that the leading end and trailing end of the stack are substantially parallel to one another and orthogonal to the travel path.
