Abstract: An apparatus forms stacks of interfolded sheets. First and second folding rolls receive the plurality of sheets, move the plurality of sheets through the nip, and fold the plurality of sheets into a stack of interfolded sheets downstream of the nip. A packing finger is associated with each folding roll, and the respective packing fingers move between a retracted position and an extended position relative to the corresponding folding roll with alternate movement relative to each other between the retracted position and the extended position to engage the plurality of sheets and form the stack of interfolded sheets. A fluid delivery system delivers fluid to a sheet in the plurality of sheets at or after the folding rolls.

Abstract: A pull station has top and bottom continuous loops with the top continuous loop disposed on a frame and movable relative to the bottom continuous loop with a frame actuator connected with the frame. The frame actuator has a sensor for sensing position. A stop, adjustable with a stop actuator and having a load sensor, is operatively engageable with the frame and prevents movement of the top continuous loop toward the bottom continuous loop. A control determines a distance between the top and bottom continuous loops based upon the actuator position sensor; determines a force imparted to webs based on the stop load sensor, the weight of the frame and the top continuous loop, and a force imparted to the top continuous loop by the frame actuator as the webs are conveyed in the pull station; and controls the pull station based upon the distance and/or force measurements.

Abstract: A converting line has a unwind machine with a load station assembly and a vertical movement assembly. The load station assembly rotatably supports a roll as the web is unwound during a first portion of an unwind cycle. The vertical movement assembly rotatably supports the roll during movement between lowered and raised positions during a second portion of the unwind cycle. A lower brake assembly controls rotation of the roll in the load station assembly, and an upper brake assembly controls rotation of the roll with the roll in the vertical movement assembly. With the roll rotatably supported in the load station assembly, the converting line control generates signals for the lower brake assembly to control an unwind rotation rate of the roll. With the roll rotatably supported by the vertical movement assembly, the control generates signals for the upper brake assembly to control the unwind rotation rate.
