  • Patent number: 5611949
    Abstract: Apparatus and method for separating book covers or other items joined by a continuously moving web. A double-walled tubular attachment strip is adhesively attached to the spine portion of successive spaced covers in a continuous process. Covers are fed onto a conveyor at a constant speed with a spacing between covers and adhesive is applied to the spine areas. Simultaneously a continuous double-walled attachment strip is formed and pressed onto the cover spines to form a continuous string of covers. The attachment strip is cut by laser cutting beam between each cover while the covers are moving by moving a focussed cutting beam in a plane normal to the plane of the strip transversely to the direction of movement of the strip.

  • Patent number: 4466606
    Abstract: An improved sheet jogging apparatus allows for easier access and quicker maintenance by placing the primary components of the apparatus above the top panel of the bin unit of a collator/sorter. Quicker adjustment of the sheet jogging apparatus to accommodate different sizes and widths of paper is easily accomplished with a sliding shaft-slot-and-set screw means. Placing the components of the jogger on top of the panel alleviates problems of assembly where the limited space between the shelves of the bin unit and the top panel make work difficult and alleviates the problem of maintenance where the shelves must be removed for access to the components of the standard sheet jogging apparatus. A source of reciprocal motion mounted on top of the panel is connected to jogging bars which extend downwardly from the panel beside the shelves and which are capable of movement responsive to the source of reciprocal motion to jog the side edges of stacks of sheets on the shelves into alignment.

  • Patent number: 4449706
    Abstract: An improved drive system for a tandem collator obviates the need for multiple motors to drive the various components of the several modules. In a simple manner, the drive train of this invention achieves greater electrical efficiency with reduced maintenance by using a direct current motor to drive a shaft which extends into the primary bin of the primary module and which has coupling means to extend through the primary module into secondary modules attached in tandem. Power takeoff means associated with the line drive shaft power the various elements of each bin, particularly the deflector assembly. A preferred power takeoff includes a plurality of idler and drive sprockets associated with the drive shaft, a driven shaft which is transverse to the drive shaft, and a three-dimensional endless belt which runs between and around the various sprockets.

  • Patent number: 4315621
    Abstract: A collator mechanism for transporting and feeding sheets of material such as paper, microfiche film or the like to individual bins. The sheets are carried by an apertured conveyor tape which slides along an apertured vacuum manifold so that the sheet is maintained in contact with the tape by the vacuum. The conveyor tape delivers the sheet to a deflector assembly which is progressively stepped through a plurality of indexed positions adjacent the bins. The deflector assembly includes upper and lower deflector rollers which bend the tape and sheet sufficiently to feed it toward the adjacent bin, release the sheet from the tape and then bend the tape away from the sheet being conveyed and the adjacent bin. The momentum and rigidity of the sheet carries the sheet, after its release from the tape, into the adjacent bin.

  • Patent number: 4173113
    Abstract: The cable includes continuous glass filaments which are helically plied in rovings at a constant helical angle from cable center to outer surface and bonded together in elastomeric material. When heated, thermal elongation of the filaments is opposed by simultaneous radially directed thermal volumetric expansion of the elastomeric material. Thus, with respect to overall cable length, thermal elongation of the cable is opposed by a simultaneous increase in cable cross sectional area such that thermal elongation effects are controllable, dependent upon the thermal expansion properties of the filament and elastomeric materials used, by controlling the helical angle at which the filaments are plied to obtain either expanding, contracting or constant length cables, as desired. Thermal contraction effects produced by cooling the cable also are controllable by controlling the helical angle.
