Abstract: A method of controlling stack back pressure in folding apparatus incorporating sensing the bulk of a stack issuing from folding rolls, forming a signal corresponding to the sensed bulk, comparing the signal with a predetermined signal range and changing the size of an embossing nip gap or pressure whenever the signal is outside of the range.

Abstract: A surface winder and method in which a stationary upper winding roll, a lower movable winding roll and a rider roll form a three roll cradle, the lower winding roll being reciprocated to control the position of a partially wound core until the rider roll returns to cradle position after permitting passage of a previously wound log and in which a compensator roll is provided to control web slack after cutoff and transfer.
