Abstract: A severing and spool assembly employs various weakening devices and techniques to provide a shear force along a narrow elongate portion of the web. One method involves scoring a paper web being spooled in a manner to provide for a controlled tearing along the scored web across its width. A portion of the web adjacent the origin of the score is attached to a take up spool using an adhesive flag member. The change in direction of the spool from roughly horizontal to nearly vertical places forces on the web sufficient to cause web tearing in a manner substantially following the score. High pressure air may be used to assist the vertical turn up action of the paper onto an empty spool.

Abstract: Improved system for controlling the forming and dewatering of a web of paper by submerged drainage in which air does not penetrate the fiber/aqueous dispersion and the formed web. The dewatering is via altering the natural tension of the meniscus of the water to induce enhanced drainage of water from the aqueous dispersion of paper making fibers in the wetter end of the system and from the drier end of the fabric. Also, the improved horizontal system provides substantially equivalent side surfaces to the paper formed in such system.

Abstract: An elongate transfer tape assembly includes a water-resistant removable top and bottom liner with two adhesive strips, one which may be water soluble, the other water-resistant, between the liners and mounted on opposite sides of a carrier. The carrier preferably is wider than the adhesives to provide mechanized gripping area remote from the edge of the assembly being fed into the nip between a collecting spool and web drive roller. A water carrying pad preferably is mounted on the bottom of the carrier that when forced against paper by insertion into the nip will weaken the paper by contact with the pad or expulsion of water from the pad. Water may also be carried by the water soluble adhesive that is applied to the bottom of the carrier in lieu of the pad. The paper will attach to the tape assembly and be drawn to a collecting spool to which the tape assembly is attached. The paper will break along its weakened portion.

Abstract: Method and apparatus for tying bundles with straps made of paper pulp fibers. The machine is positioned transverse to a conveyor upon which bundles are moved into position for tying. The machine includes a track for guiding the strap around the bundle, applying an adhesive to the forward end of the strap, clamping the forward end of the strap, tightening the strap around the bundle, pressing the forward end against an overlapped portion of the strap until the adhesive cures, cutting the rear end of the strap, and releasing the bundle to be conveyed to a position for unloading from the conveyor.

Abstract: A device in a cassette container for applying a strip of double-sided adhesive to a surface which comprises a rotatable supply roll of a composite tape consisting of a strip of double-sided pressure-sensitive tape adhered to a backing layer strip, a transfer roller adapted to receive the composite tape, temporarily adhere to the tape and, after rotating through a portion of a turn, apply the adhesive strip to a receiving surface. A return bend surface is provided near the transfer roller for separating the backing layer from the adhesive strip adhering to the transfer roll; a channel leads the stripped backing layer away from the transfer roll, and a braking means selectively prevents rotation of the transfer roller and releases the roller for free rotation.

Abstract: An elongate transfer tape includes a water-resistant removable top and bottom liner with two adhesive strips, one water soluble, the other water resistant, side-by-side in a plane between the liners. Above the water resistant adhesive is a water absorbent pad that when forced against paper will weaken the paper by the forced expulsion of water from the pad. The paper will attach to the tape and be drawn to a collecting spool to which the tape is attached. The paper will break along its weakened portion. The pad is constructed to hold water against the centrifugal forces that derive from the rotating collecting spool to which it is attached via the water resistant adhesive.

Abstract: A system for feeding a cutting tape for a paper wind up machine along a track guide to apply a strip of adhesive to the forward end, measure it and cut the tape to a desired length, store it temporarily in the form of a hanging loop, feed the adhesive coated forward end to the exit end of the track adjacent a new roll for wind up of a paper web, and a brake to provide resistance to the tape so as to become tension to cut the web of paper and transfer it to the new roll.

Abstract: Improved apparatus for controlling the dewatering of a web (44, 44') in a Fourdrinier fabric (20, 21) by submerged drainage apparatus in which air does not penetrate through the fiber/aqueous dispersion nor the formed web (44, 44'). The dewatering is accomplished by altering the natural tension of the meniscus of the water to induce enhanced drainage of water from the aqueous dispersion of paper making fibers in the fabric (20, 21) and replacement air for the water draining from the formed web (44, 44') is provided from beneath the lower fabric (20) and, if an upper fabric (21) is employed, from above the upper fabric (21).

Abstract: A laminated carrier containing, between a base sheet and a cover sheet, a plurality of encapsulated liquid adhesive bubbles in spaced apart locations. The laminated carrier includes an adhesive backed paper strip including tear perforations between adjacent liquid adhesive bubbles, and a crush resistant element in the form of a wire may be laminated with the paper. The wire may have a sharp edge or apex facing upwardly from the base sheet. The strip may include other spaced liquid filled bubbles alongside the adhesive filled bubbles.

Abstract: Method of feeding separate streams of (1) an aqueous dispersion of pulp and (2) white water from a paper making process into a wedge-shaped space between horizontal travelling upper and lower converging wire meshes, applying a siphon means to the upper wire mesh in said zone to form a web of solid fibrous material between the meshes separating the upper wire mesh from the web to leave it supported on the lower wire mesh as the meshes leave the wedge-spaced zone; washing all solids from the wire meshes into a receiving vessel, recycling the contents of the receiving vessel to the paper making process, and recycling the liquid from the white water to the paper making process; and apparatus to perform the above method.
