  • Patent number: 10538018
    Abstract: A method includes processing multiple macromolecular staples to successively produce a macromolecular sheet body, multiple silks and multiple sheet particles. The macromolecular sheet body contains multiple district camouflages and is processed by edge cutting to form multiple color strips. The color strips, the silks and the sheet particles are processed and attached to the surface of the macromolecular sheet body, so that the surface of the macromolecular sheet body forms the district camouflages, the thread camouflages and the spot camouflages. Finally, the macromolecular sheet body is vulcanized or solidified in a foam molding zone, to form an elastic mat with a mixed color type.

    Abstract: An electrode production system includes a kneading device to which replaceable cartridges that respectively contain electrode materials and a solvent can be fitted. A supply passage for supplying a kneaded material is provided between the kneading device and the coating device. This eliminates the possibility that impurities, such as dust, dirt, or moisture, may be mixed into the kneaded material. Therefore, electrodes with high quality can be produced. Furthermore, it is possible to continuously perform processes from kneading to coating, and there is no need of performing the kneading in a batch process. Thus, the operation can be easily performed.

  • Patent number: 8273286
    Abstract: Systems and methods are described where at least one roller (e.g., a kicker roller) is used to impregnate fibers (i.e., a charge or reinforcement) with a liquid resin (i.e., matrix) by eliminating air from the resin and fibers as they enter a pressurized zone. Air is forced out as the resin is first drawn into an entry zone of the roller, then into an entry gap adjacent to the roller, and then into the pressurized zone on the opposite side of the roller. The pressurized zone is an enclosed area at the output side of the roller where the resin is allowed to accumulate and the resin and composite combination are then forced out through a small exit gap. Shear forces between the surface of the quickly rotating driven roller and the resin provide the driving force. The fibers may be continuous (e.g., from a roller) or discontinuous or loose cut.

  • Patent number: 5895542
    Abstract: A coater and method allow for an essentially dry coating process. In this process, a coating is continually applied to a casting drum. This casting drum will rotate to move the coating passed infrared drying units. The exterior face of the casting drum is cooled. The temperature of the coating will rise except at an area adjacent the casting drum. This will reduce the water concentration of the coating except at the area adjacent the casting drum. This arrangement prevents the coating from bonding to the casting drum. Therefore, the coating can easily be removed from the casting drum and applied to a final substrate.

  • Patent number: 5873969
    Abstract: A method and apparatus for manufacturing recloseable plastic bags with engageable mating profiles where the bags are provided open for the consumer. The profiles are initially provided in the fully engaged condition within an elongate, longitudinally cut tube. The profiles are then periodically fused, tacked, or attached together at the approximate locations where the tube is to be cut into bags. Upon tacking, the profiles are pulled apart by frictionally engaging an area on the outside of the film, near the profiles, and between the tacks. The film is then forced away from the profiles, which at least partially pulls one profile from the other. Thereafter, the tube may be cut and sealed into bags as would otherwise normally occur.

  • Patent number: 5750444
    Abstract: A breathable laminate comprises at least two porous webs laminated together with a porous adhesive matrix, preferably a random fibrous adhesive pattern having a coat weight of between 1.5 and 12 grams per square meter. The two or more porous webs comprise woven or non-woven materials and the resulting breathable fabric or laminate has good hand and flexibility. Breathable fabric is adhered to foam by such random fibrous adhesive patterns of similar coat weights. Coating widths of up to 80 inches or more are produced in a slot die fed by a selected plurality of recessed lands within the die, with motors and pumps controlled to maintain consistent, uniform coat weights regardless of coat widths and substrate speeds selected. Single ply coated webs, apparatus and methods are disclosed.

  • Patent number: 5298097
    Abstract: An apparatus and method provides for thermally bonding a textile web while supporting the web continuously from the lay down point until the web is thermally bonded. The apparatus includes a heated transfer roll adjacent an endless moving belt. The transfer roll is located outside the belt loop on the opposite side of the belt from a guide roll. The belt passes around a first portion of the transfer roll with the web sandwiched between the belt and transfer roll. The heated transfer roll heats the web and the web is transferred to the transfer roll.

  • Patent number: 5174845
    Abstract: The insulating coating for an object such as a rocket motor casing is formed by wrapping a strip of insulating material upon the surface of a rotating mandrel. By means of this invention, it is possible to wrap a strip of malleable material such as rubber from an extruder onto a complex shape while exercising precise thickness control, thereby eliminating the need for machining the outer surface. The strip is run through a forming mill of unique construction which shapes the strip during the wrapping process to conform most precisely with the topography of the mandrel. The mill automatically varies both the taper and the width of the strip. The final wrapped product has a smooth outer surface that requires minimal finishing.
