Abstract: A device for sequentially introducing sheets placed in a stack into the nips of a pair of introduction rollers comprising at least one linear member having ends secured to a control pulley or roller and passing around a return pulley or roller which is adjacent the nips of the introduction rollers. A plurality of cams mounted on rotating shafts for engaging a run of the linear member to shift it from a retracted position to a position for engaging a bottom sheet in a stack disposed above the linear member, a vacuum chamber disposed along each linear member for holding the sheet on the members as they engage the sheet and carry it toward the nips.

Abstract: A rotary stacker and method wherein a stream of web units such as napkins is advanced along a longitudinally extending path in longitudinally spaced relation toward and over a magazine, each napkin being pressed into the magazine by cams applying pressure at a plurality of longitudinally spaced areas over the magazine and orienting the cams so as to remove the pressure on the upstream cam just prior to the entry of the leading edge of a unit subsequent to the one being pressed and while maintaining the pressure on the previously pressed unit by the downstream cams.

Abstract: The present invention is directed to a container for dispensing tablets in a non-reversing manner. The container includes a main container body, an actuator disk and a stop. The main container body is adapted to receive at least one stack of tablets and has an operating orifice and at least one annularly located ejection post. It is adapted to receive and rotatably hold the actuator disk so as to render it rotatable about a central axis. The actuator disk has a first recess which form a complete annulus about the central axis and is coincidental to and mates with the ejection post. The actuator disk also has a recess of width and depth sufficient to receive a predetermined number of one or more tablets, which has an inward end which is at least coincidental with the dispensing orifice when located thereunder and an outward end which is open for tablet dispensing. The container also includes a stop to assure that said actuator disk can only be rotated in one direction.
