Abstract: A positionable-repositionable pressure-sensitive adhesive may be repeatedly applied to a surface and removed during an initial installation time period. The adhesive contains an adhesive base resin and coacting detackifying resin and particulate components which temporarily reduce the tack and peel strength of the adhesive. Upon passage of time and/or application of thermal energy, adhesion build-up occurs to a maximum value. The pressure-sensitive adhesive may be used as an adhesive layer in a laminate for tapes, signs and decorative and protective applications including vehicle marking and architectural installations.

Abstract: A process of making backed, pressure-adherent carpeting. A construction is assembled comprising a backing-film and an adhesive on one side of the backing film, and then, in a separate step, the other side of the backing film is heat-laminated to a web of carpeting to thereby reinforce the carpeting and provide it with an adhesive. The carpeting is both reinforced and rendered adherent in a single pass of the carpeting and at a single station in the carpet-manufacturing line.

One end of the mailer detaches from the remaining portion of the mailer and comprises a reply envelope which the addressee may send back to the sender of the mailer in response to a message printed on the second sheet opposite the transmittal envelope portion.

Abstract: A high security label is disclosed which includes a multiple layer security label with a base layer with a permanent adhesive coated on its lower surface. Indicia or markings are applied to the bottom surface of the top layer. The top layer is laminated to the upper surface of the base layer by a permanent patterned adhesive. The patterned adhesive is formed so as to leave a portion of the upper surface of the base layer and the bottom surface of the top layer free from adhesive. The markings are applied to the bottom surface of the top layer in at least the adhesive free areas.

Abstract: A label printer and dispenser web transport system includes a motor driven platen and a print head resiliently directed against the platen between which an ink foil and label web are passed. The web travels over a triangular peeler bar disposed closely adjacent the platen and is then returned to the platen for passage between the platen and a spring biased idler roll deformably engaging the platen to maintain web tension over the peeler bar. The print head is pivotally mounted and is moved out of engagement with the platen when the print head is not printing. The ink foil is not advanced when the print head is moved away from the platen.

Abstract: A variable size envelope with a single closure flap that may be selectively folded along either of two different fold lines to provide two different sizes of envelopes. A pocket for holding papers or other documents may be formed by a single rear panel or two rear panels joined together. The height of the closure flap is preferably equal to the height of the panels so that the envelope when folded into a smaller size presents a flat envelope of uniform thickness which may be processed through automatic mechanical printing equipment, laser printing equipment and copying machines, then unfolded and later used as a larger size envelope. Adhesive strips are provided on the closure flap for the purpose of sealing the envelope. The adhesive used for the strips is preferably a stable, water-activated, or moisture-activated adhesive, which is not significantly affected by either heat or exposure to high humidity facilitating use of the envelope during laser printing or xerographic copying.

Abstract: Film-forming means are coextruded to form all plastic multilayer liners and facestocks for pressure-sensitive labels, tapes, decals, signs, bumper stickers, and other products formed from sheet and roll stock. Fill means in a change for the liner coextrusion affects stiffness and dimensional stability of the liner and/or affects the roughness of a liner face or faces. The film materials of the layers of the constructions are selected according to the cost/benefit characteristics of candidate materials considering the functional or operational requirements of the layer in question.

Abstract: A brushless white-out correcting fluid applicator for use in applying white-out fluid to paper without using a brush. The white-out fluid is a suspension including a substantial proportion of white or substantially white particles, such as titanium dioxide, or other color particles. The applicator includes a wear-resistant, porous tip and a regulator between the tip and a reservoir. The regulator may be formed of foam material, and the tip may be of sturdy porous plastic. The size of the pores in the tip and regulator are large enough so that they do not become clogged with particles in the white-out fluid. The regulator prevents the tip from dripping by regulating the rate at which fluid can leave the reservoir. The size of the pores adjacent the reservoir may be different than the size of the pores and passageways adjacent the tip. The applicator may be provided with an air-tight cap to avoid drying out between uses.

Abstract: An envelope having a single peel-off backing sheet covering strips of pressure sensitive adhesive located along the sides of a panel of the envelope, which facilitates processing through automatic mechanical sheet feed printing equipment, laser printing equipment and feed through copy machines prior to folding the panel in order to form an envelope. Before the panel is folded, the panel, peel-off backing sheet, and peel-off strip attached to an adhesive strip on the envelope's closure flap provide a flat sheet of uniform thickness which can be easily processed through printing and copying equipment. After indicia is printed on the panel or copying is completed, an envelope may be formed by peeling the single backing sheet off the pressure sensitive strips, folding the envelope about a fold line located near the middle of the panel, and pressing the strips of pressure sensitive adhesive at the sides of the panel together so that a pocket is formed for holding a letter or other document.

Abstract: Dual layer, pressure sensitive label sheets for ion deposition printing, use an adhesive on the back of the labels in the form of geometric patterns with narrow, adhesive-free bands between the geometric patterns. The patterns may be hexagonal or diamonds, for example, so that the edges of the die-cut labels will be held down; and the adhesive-free areas may be less than 1/16 inch, preferably in the other of 1/32 inch in width so that with the high pressures encountered in ion deposition printing, curl-free labels with high resolution printing is achieved.
