Abstract: A sheet separating device for removing an uppermost sheet of an adhesive pad containing a plurality of such sheets includes a housing; a support plate for holding the pad, resiliently biased in an upward direction. A sheet separator mechanism is movable in forward and reward directions, includes a frame, a pick wheel mounted for rotation within the frame, and a knife blade having a closed periphery opening therein defined in part by at least one entry projection, wherein the pick wheel is located ahead of the at least one entry projection of the knife blade in the forward direction such that, in use, the pick wheel lifts an edge of the uppermost sheet extending transverse to the forward direction, and the at least one entry projection of the knife blade then moves between the uppermost sheet and a next underlying sheet as the uppermost sheet passes through the closed periphery opening.

Abstract: Business forms having labels integral with the sheets there of (rather than riding piggyback thereon) are produced by applying a strip of transfer tape to only a portion of the second face of a sheet, with the adhesive of the transfer tape contacting the sheet, so that sheet material surrounds the transfer tape strip completely. Then a label is die cut from the first face of the sheet, preferably after the transfer tape is applied, within the area of the sheet overlying the transfer tape strip, without cutting the transfer tape backing. Indicia is at some point printed on the first face of the sheet. The label may be readily removed, with the adhesive from the transfer tape sticking to the label while the backing of the transfer tape remains in place. The strip of transfer tape is cut from a web, and then is transported with the adhesive face outward by a vacuum cylinder, until it moves into contact with a moving web.

Abstract: Easily removable labels, which are still permanently placed except when it is desired to remove them, are associated with bottles, cans, or like containers. Two different configurations of the labels are provided. In the first configuration a roll of labels is provided with permanent adhesive strips along the edge of each label being in shingled overlapped engagement with the permanent adhesive release coat of an adjacent label. In a second construction a pad of labels is provided with two different types of labels, each type having spaced strips of permanent adhesive along one edge of each of the top and bottom faces, which are staggered with respect to like strips along the edges of the second type of labels in the pad, the types of labels alternating in the pad, and permanent adhesive release coat material being provided in the spaces between the strips of material.

Abstract: A system for collecting paper trim and dust automates and simplifies the removal and disposal of trim. The system includes a funnel receiving the paper trim from an automatic trimmer, a drum and rewinder for winding the paper trim into a bale, and a dust trap for sucking dust from the drum and funnel into a dust bin. As the trim is baled, the rewinder drags the paper bale against the side of the drum. This drag compacts the bale and increases the load on the rewinder. As the drag load on the rewinder increases, the rewinder is moved radially towards the center of the drum to increase the distance between the rewinder and the drum wall. A current sensing circuit triggers the radial movement of the rewinder when the current load on the rewinder motor exceeds a threshold limit. This radial movement reduces the drag on the rewinder. When the rewinder reaches the center of the drum and the trim bale fills the drum, the rewinder is stopped and the trim bale removed.

Abstract: Cleaning apparatus for an imaging cylinder in an ion deposition printer includes a housing having an upper portion and a lower portion, separated by an internal plate.

The ink composition is resistant to leaching upon contact with, for example, water.

Abstract: Pressure sealing of business forms is effected utilizing first and second sets of (preferably narrow-width) rollers forming first and second nips which provide a sealing force to business forms passing between them. The first set of rollers are rotatable about first and second axes, typically horizontal, while the second set of rollers are rotatable about third and fourth axes. The third and fourth axes are substantially perpendicular to the first and second axes, and may be horizontal or vertical. The first set is typically provided above the second set, and a conveyor may be provided for conveying forms which drop from the first set into operative association with the second set.

Abstract: Discrete overlying sheets form a pad or chart with the sheets secured one to another along an upper margin. Strips of repositional adhesive are coated along the back side of each sheet adjacent the upper margin between weak and strong lines of perforations. The top sheet may be removed from the pad or chart by tearing along the weak line of perforations and adhered to a support surface using the repositional adhesive. The sheet may subsequently be removed from the support surface by tearing along the strong line of perforations. The ends of the lines of adhesive may be formed in various patterns to provide additional coated areas or additional uncoated areas.

Abstract: A two part shipping form has top and bottom plies with a shipping label operatively mounted on the second ply. Image transfer mechanisms, such as CF and CB coatings, are provided on the bottom of the first ply and the top face of the label and the second ply. Beneath the pressure sensitive adhesive of the label is a silicone coating or a transparent release material ply to allow the label to be removed from the second ply. Beneath the silicone coating is a self-contained spot, so that indicia written on the top ply transfers to the top face of the label and to the top face of the second ply beneath the label. The forms are made on presses and by blowing the label, with or without the transparent midply, onto the second ply.

Abstract: A business form is constructed from a top paper ply, a transparent (e.g. Mylar) second ply, a third ply having a carbon spot on its back face, and a fourth paper ply. Indicia imprinted on the first ply is transferred to the fourth ply. The first and third plies are readily removed, and a "pocket" is formed by the second and fourth plies. Strips of transfer tape are on the rear face of the fourth ply, which is slit and has fold lines formed so that it may be folded into a packing list configuration, having a basically sealed construction. The packing list may be readily opened by tearing along perforation lines.

Abstract: A security document that provides an indication it is a copy when copied by a photocopy machine has printed background pattern and warning printer matter interspersed with blank areas of a substrate to provide a distinct intermeshed pattern so that the warning printed matter is indistinguishable from the printed background by the human eye. The printed background comprises a number of parallel lines of a size such that they will be resolved by a photocopy machine, while the warning printed matter comprises geometric elements (typically circular dots) of a size less than that which can be resolved by a photocopy machine. The dots are disposed in a geometric continuation of at least some of the lines from the printed background, and are configured to form invalidating indicia of the document is copied by a photocopy machine. The printed background pattern and warning printed matter typically have a density of less than 20%, such as about 7-11%.

Abstract: A business form intermediate comprises a sheet that is C-folded first about a first fold line and then a second fold line to define a mailer. The business form has first, second and third panels with an outgoing address area on the first face of the second panel, and an O.P.A.S. patch on the first face of the first panel. The patch obscures a PIN number or other confidential information underneath it. Pressure seal adhesive formed along the margins of the paper sheet of the intermediate holds the panels together once C-folded. Masking is applied on panel faces as necessary in order to obscure all interior information of the mailer.

Abstract: Encapsulated electrostatographic toner particles and a process for making toner particles. The toner particles comprise a pressure fixable core encapsulated in a pressure rupturable shell with the outer surface of the shell being hydrophobic. Preferably, the outer surface of the shell is rendered hydrophobic by having a thermosetting resin precipitated thereon. The process for producing electrostatographic toner particles comprises preparing a core material, encapsulating a discrete portion of the core material in a shell by interfacial polycondensation, and then treating the outer surfaces of the shells with a thermosetting resin to render them hydrophobic. This enables the particles to be formed as a free-flowing, dry powder without requiring costly spray drying.
