Abstract: A portable easel with adjustable board support which has a plurality of legs pivotally joined together by a head, the legs of which may be selectively spread apart when set up as an easel and folded together when collapsed, each leg composed of multiple interlocked sections biased together when in extended position but which may be manipulated for separation and folding into a bundle one section against another section for storage and transport, and a board support mounted on at least one leg which may be selectively adjustably moved to a desired position on any of the sections and moved against the leg on which it is mounted for storage and transport and extended away from the leg for holding a display on the easel when set up.

Abstract: The present invention provides new paper shredding devices mountable on various horizontal and vertical surfaces. The paper shredder has a housing defining a paper inlet and a shredding knife in the housing positioned downstream of the paper inlet. A shredding knife controller is connected to the shredding knife. A shredded paper receptacle is positioned downstream of the shredding knife. A bottom of the housing serves as a tabletop mount for standing the shredder on a tabletop. One or more holes may be provided in the back side of the housing to permit the shredder to be mounted on a wall.

Abstract: The present invention provides document shredding devices mountable on various waste receptacles for shredding paper. The document shredding devices have a housing defining a paper shredding passageway. A paper shredding mechanism is contained within the housing and extends into the paper shredding passageway. A mounting support adjustably extends from a waste receptacle mounting side of the housing while remaining housing sides are free of waste receptacle mounting supports. The mounting support has a position retracted into the housing which defines a substantially linear mounting channel and another position extended outward from the housing which defines a nonlinear mounting channel.

Abstract: The present invention provides new offsetting paper stacking devices and methods which automatically stack sheets of paper into groups which are offset from each other. The offsetting paper stacker stacks sheets of paper that are feed into an input end of the device one at a time at a high rate of speed. The paper is stacked in one pile, however, within that pile there are groups of sheets that are stacked at a sideways offset to the group immediately above and below. Accordingly, every other group of sheets of paper will be in line with each other and each adjacent group will be offset from each other. The offsetting paper stacker includes stacker wheels which are rotatable about two axes of rotation to stack the paper in an offset manner.

Abstract: A personal binding machine for assembling a preformed coil into a stack of prepunched sheets which includes a loading tube assembly that properly orients the coil to be driven into the stack of sheets, a drive assembly which drives the coil into the stack of sheets, and crimping assemblies for crimping the ends of the coil once inserted into the sheets. The drive assembly includes a three surface contact system having a coil guide substantially adjacent the edge of the stack of sheets, a drive roller and an idler roller. While the coil guide is stationary within the housing, the location of the drive and idler rollers may be adjusted via a camming system to accommodate various coil sizes. The crimping assemblies include a cradle and blade mechanism wherein the blade presses an end of the coil into a cradle to bend or crimp the end. The drive roller may alternately be directly accessed to manually drive the coil through a stack of sheets.

Abstract: A housing including a support arm arrangement for a basket mounted paper shredder wherein the support arms have curved or rounded outside perimeters and at least one of the support arms has a curved or rounded inside support rib arrangement to more closely conform to a rounded waste paper basket. The support arm arrangement allows the paper shredder to be mounted to both round and rectangular waste paper baskets. The housing also provides a streamlined shape including a tapered generally triangular motor wiring compartment.

Abstract: A machine is disclosed for withdrawing a spiral coil from a prepacked cartridge set of coils and spirally feeding that coil to a coil guide. A stack of sheets having prepunched holes along a side edge thereof is located so that its prepunched holes are aligned with the coil guide. A rotatable drive roller, proximate the coil guide, engages the withdrawn coil and spirally feeds the coil through the coil guide, such that the spirals of the coil sequentially pass through the prepunched holes. After the lead end of the coil has passed through the prepunched holes of the stack of sheets, it is crimped. The drive roller then reverses direction to spirally feed the coil backwards through the coil guide, whereupon the tail end of the coil is crimped. The movements in the machine are designed to vary dependent upon size of the coil.

Abstract: A cartridge box serves as supply container for a plurality of spiral coil elements and is thus suitable for use in a system for automated repetitive spiral binding of sheet stacks. The cartridge box contains the individual coil elements in a series of parallel rows. One elongated opening is formed in the cartridge box top or bottom surface to expose intermediate portions of the coil elements to a driven feed roller. Another elongated opening is formed along a sidewall of the cartridge box for extraction of coil elements therethrough in endwise fashion under the influence of the feed roller.

Abstract: A method of one sided laminating and a one sided laminated product using nylon laminating film reduces the tendency of one-sided laminations to curl toward the laminating side due to moisture swelling of the paper side of the lamination.

Abstract: An apparatus and method for successively delivering ring carrier elements to a paper loading station for producing bound booklets. The apparatus provides a carrier having ring elements adhesively attached thereto in spaced apart fashion, the carrier drawn to a ring loading station where individual elements are deposited onto a comb retainer whereat a ring spreader can open the rings for loading of paper thereon. The carrier can be fashioned as a fan-folded supply or can be a wound supply, having the elements adhesively attached thereto, or threaded thereon.
