    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.

  • Patent number: 5628861
    Abstract: A method for manufacturing a laminate comprising at least two sheets of magnetic material is disclosed. The laminate may be used to form a stacked transformer core. The method increases the productivity of the core-stacking process, decreases the core loss destruction factor, decreases total core loss, decreases acoustic noise generated by the electrical device employing the laminate, and does all of this in a manner which is commercially practical. The method comprises applying an adhesive, preferably a hot melt adhesive, in a pattern of thin beads onto one side of a first lamina or sheet of magnetic material, the pattern comprising a plurality of lines, the lines being substantially parallel to each other and substantially perpendicular to a direction of grain orientation or rolling direction of the lamina. A second lamina is then stacked onto the one side of the first lamina, and then a compressive force is applied to specified areas of the laminate.

    Abstract: For forming a fine pattern of ferroelectric film without using a resist, a solution containing polyalkoxide having ferroelectric components, as a base part, and functional groups to be activated when exposed to electromagnetic waves or corpuscular beams is used as a pattern forming agent. The pattern form agent is coated onto a substrate, and then electromagnetic or corpuscular beams are radiated thereover to form crosslinks between molecules in the agent. After the crosslinks are cured, the portions devoid of any crosslink and hence uncured are removed using a solvent. Then the molecules associated with the crosslinks remaining on the substrate are then heated to form a ferroelectric crystal.

  • Patent number: 5620544
    Abstract: A method and apparatus of forming coreless rolls of pressure sensitive adhesive tape involves the use of a mandrel assembly having a specific circumferential tape supporting segment thereon for winding tape. The circumferential tape supporting segment has a tape engaging surface portion that, in a radial orientation, is compressible yet sufficiently stiff to support the tape as it is successively wound about the mandrel to form a tape roll, and that is sufficiently pliant to permit ready axial removal of a wound tape roll from the shaft. The innermost wrap of pressure sensitive adhesive tape about the mandrel is masked by an adhesive liner. That liner is formed from one portion of a liner/tab segment which had been applied to the tape previously, and prior to winding, the tape is severed, and the remainder of that liner/tab forms an end tab on the outermost end of the previously formed coreless tape roll.

By assembling the material on a forming roll of large diameter, such that the thickness of the wound wraps of a given length of the sheet material is relatively thin, the deformation of each wrap is minimized during heat and compression curing and the cured material is free of surface wrinkles and creases. The cure-stabilized material then can be unwound and cut to desired length and wound on a small diameter shipping tube to provide a shipping package of material free of wrinkles and creases. The curing apparatus includes a cylinder with an internally lined inflatable bladder, such cylinder being adaptable to being moved into surrounding relation with the sheet material.

    Abstract: A reinforced elastomer cover for use on conditioning rolls in harvesting machines for conditioning crop material. The roll cover comprises one or more layers or plies of reinforcing material interspersed between and bonded to layers of the elastomer. The reinforcing material preferably comprises fibers of synthetic polymers or glass. The reinforced elastomer sheets are placed on roll cores and bonded or otherwise secured to the outer periphery of the roll core. The reinforced elastomer sheets are also molded or machined to possess the desired tread pattern. The sheets may be assembled and bonded directly on a roll core and thereafter vulcanized; or the vulcanized sheets may be bonded or otherwise secured to the cores.

    Abstract: Disclosed are a process for producing a tubular nonwoven fabric and tubular nonwoven fabrics produced by the same. In the process, a web is formed on a first rotating cylinder by catching fibers carried to the surface of the first rotating cylinder by a fluid, the web is transferred to a second rotating cylinder, a tube of the transferred web is formed on and around the second rotating cylinder, and the tube is drawn in the axial direction of the second rotating cylinder to form a tubular nonwoven fabric. The tubular nonwoven fabric with a high unit weight can be produced without elongating or breaking the nonwoven fabric, and the diameter of the tubular nonwoven fabric can be freely changed.

    Abstract: Apparatus for winding web material (14) comprises a reciprocating carriage assembly (22) which delivers the leading end of the web to a winding spindle (30) and then moves away from the spindle as winding proceeds. A builder roll (138) mounted on the carriage assembly applies pressure during winding. A tape tab (178) is automatically applied to the trailing end of the web and pressed onto the completed roll (140) by the builder roll, while a stepping motor (176) for the builder roll resists the winding motor to maintain tension in the final convolution of the web. A corresponding method is taught.
