  • Patent number: 5028043
    Abstract: A device for gripping and decollating a bottom blank comprises a rotary shaft with a flat outer peripheral portion. Suction orifices in the shaft extend through the flat surface portion and communicate with suction cups carried by the shaft. Free outer edges of the suction cups contact the bottom blank, whereupon the application of suction causes the suction cups to contract. The suction orifices include enlarged outer portions for receiving the contracted suction cups such that the bottom blank is pulled flush against the flat surface portion of the shaft for a more effective application of suction forces.

  • Patent number: 4872593
    Abstract: An apparatus is provided for the storage and dispensing of packaged adhesive bandages and similarly shaped flat packaged units. The dispenser includes a drive unit base, which may be powered either manually or electrically. A cartridge is removably mountable to the top of the base. The cartridge holds a stack of packaged adhesive bandages on a floor in which is defined an elongated slot. A weight is provided to exert downward pressure against the bandages toward the cartridge floor. A roller with an elastic following finger attached to the roller is mounted within the housing and aligned with the slot in the floor. When the roller is rotated the following finger frictionally engages the lowermost bandage in the stack, urging it through an exit portal at one end of the cartridge. As the bandage is propelled through the portal, it displaces a resilient flap which covers the portal.

  • Patent number: 4640504
    Abstract: An apparatus for feeding individual substrates from the top of a stack of substrates upon demand includes a paddle wheel having paddles that are semi-cylindrical. The paddles buckle upon contact with the substrates rather than bending and thereby providing reduced normal force sensitivity to paddle deflection and reduced pressure since the force of buckling is a function of the paddle cross-section rather than paddle length for all areas of the paddles except near the paddle wheel hub. The semi-circular blades reduce misfeeding and multifeeding while having an extended wear life.

  • Patent number: 4538800
    Abstract: To provide for deflection of copy between two respective paths (8, 16; 9, 17) without using switchable deflection tongues, two cylinders (3, 4) have segmental elements (24, 27) located thereon which are respectively, selectively, positionable on or within the circumference of the cylinders, or projecting therefrom, for example by securing the segmental elements in projected position, or by controllable eccenters (28-35). Copy is fed by a belt transport system between the cylinders and, if the copy meets a projecting segment, the projecting segment will deflect the copy into one of the paths, in accordance with the position of guide tongue structure (36). Alternate feed in the respective path can be obtained by offsetting the projecting segments (25, 27) from each other, for example by 90.degree. (FIG. 3) and feeding copy with equal copy length and copy spaces therebetween to the cylinders, so that the copy will be directed, alternately, to one, or the other of the exit paths.
