Abstract: An apparatus including a log accumulator is provided. The log accumulator can have logs load therein while they travel along a path that is generally parallel to a path along which the logs are separated from a building stream of sheets, such as when exiting a folder. The logs may be loaded into buckets of the accumulator without requiring lateral accelerations out of a mechanism transferring the separated logs to the accumulator. Similarly, logs may be initially removed from buckets of the accumulator without requiring lateral accelerations. Further, an accumulator unloading apparatus may initially index the logs perpendicular to a length to clear the path of the buckets of the accumulator and then accelerate the logs parallel to a length of the logs once removed from the path of the buckets.

Abstract: 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.
