  • Patent number: 5885670
    Abstract: The Conventional Direct Glazing invention concerns a process for securing fixed panes of inorganic or organic glass to vehicles or parts thereof, in which flexible structural components and or sealing strips are prefitted by a weld strip between them and the pane by thermally activating the weld strip and thus producing a seaming effect on the pane, and pane modules thus produced. A pane module thus produced can subsequently be conventionally fitted to the coachwork on the assembly line using fitting strings without any further auxiliaries and working process. Owing to the material used for the flexible structural component and or sealing strip, the sealing quality corresponds to that of direct glazing. If the residual heat from the manufacture of the pane is used as the activation heat for the sealing strip, considerable economies are achieved in the manufacturing process for the pane module.

The joint produced between the window fixing adhesive and the polymeric gasket has a bond strength and performance greater than that achieved in conventional metal-to-glass bonds using the same fixing adhesive. The panel assembly of this invention may be sent to the automobile manufacturer so that all the installer needs to do is apply the window fixing adhesive between the gasket and the vehicle in a conventional manner. The strong bond can be achieved even after the panel assembly has been in storage for days, weeks, or even several months prior to installation. The panel assembly includes a gasket bonded to a sheet-like panel and having a surface adapted to receive a window fixing adhesive for bonding the sheet-like panel in the vehicle opening.

  • Patent number: 5643385
    Abstract: A method of integrally bonding a foam seat pad or other article to a cover material, includes steps of coating a main surface of the pad with a heat activated adhesive. Then, the pad is affixed to an upper mounting member. A lower mounting member is positioned opposite the upper mounting member and the cover material is disposed on the lower mounting member. Heating is applied to the adhesive coating the main surface of the pad, and when sufficient heat is applied the upper and lower mounting members are pressed together for a predetermined time period. Clamps are provided on the mounting members for surely positioning the pad relative the cover material. Thus, accurate positioning and strong bonding are reliably assured.

  • Patent number: 5635003
    Abstract: To form a prebonded composite structure, a laminate composite is prepared by positioning a first layer of heat-activated adhesive between a first fabric layer and a second side of a pad and a second fabric layer is positioned adjacent a second side of the pad. The laminate composite is heated to produce a heated laminate composite and the heated laminate composite is positioned between an upper mold and a lower mold. The laminate composite is compressed between the upper and lower molds, thereby compressing the first layer of heat-activated adhesive between the pad and the first fabric layer. In one application, dielectric heat is applied to the laminate composite during the step of compressing the laminate composite.

  • Patent number: 5635015
    Abstract: An Apparatus for applying cushion gum to a periphery of a tire casing without cement includes a conveyor having a forward roller near the tire casing. The conveyor is mounted on a carriage that is movable relative to its base so that the conveyor can be moved to contact the tire casing. The conveyor moves the cushion gum below an infrared heater to heat an interface side of the cushion gum to increase its tack and then moves the heated cushion gum between the forward roller and the tire casing. The forward roller of the conveyor applies the cushion gum to the periphery of the tire as the cushion gum exits the conveyor and first contacts the tire casing. A supply roller is provided to move the cushion gum from a supply roll to the rear end of the conveyor. A cutting mechanism is provided between the supply roller and the conveyor to selectively cut the cushion gum.

  • Patent number: 5605593
    Abstract: By providing a multi-layered, self-sealing, adhesive system constructed for being laminated directly to a thermoplastic or elastomeric elongated tube, a highly effective, easily employed, closure system for securely sealing the elongated slit of elongated, thermoplastic or elastomeric tubes is obtained. In the preferred embodiment, the multi-layered, self-adhering, sealing system of this invention is manufactured in a substantially continuous elongated strip and incorporates a laminating film layer and a film support layer. In this way, secure, integral bonded affixation of the sealing system to the elongated tube is attained in a unique cost-effective, highly efficient manufacturing process. In addition, by integrally affixing the laminating film layer and the film support layer along both sides of the elongated slit of the tube, an adhesive engaging surface is provided for assuring secure, leak-free sealed closure of the elongated tube.

  • Patent number: 5552014
    Abstract: A torch assembly for use in fabricating and repairing roof joints includes an elongated handle presenting a forward upper end and a lower rearward end, and a torch supported adjacent the lower end for directing a flame away from the handle. A roll of bituminous material is supported on the apparatus so that the material may be dispensed from the roll in a rearward direction as the apparatus is pulled forward by the handle. An elongated shoe is supported on the handle and includes upper and lower wall sections which are connected together at the rear end of the shoe, and at least one side wall section which extends between the upper and lower wall sections and defines a flame-receiving cavity for substantially surrounding the flame directed by the torch. The shoe diverts the flame in the flame-receiving cavity upward and rearward toward the bituminous material being dispensed from the support means so that the bituminous material is heated as it is applied along the roof joint.

  • Patent number: 5543010
    Abstract: A document laminate includes laminating sheets with adhesive on facing sides to laminate a document between the sheets, and shielding sheets covering the document and received within the laminating sheets. When the adhesive is heat activated, the shielding sheets are selected to be not degraded by the activating heat. A document can therefore be removed from the laminate by cutting along a line at one edge of the shielding sheets, and removing the document, which is not adhered to the shielding sheets or the laminating sheets.

  • Patent number: 5531846
    Abstract: Resealing apparatus for closing the toner-dispensing slot of a toner cartridge, preparatory to refilling that cartridge with toner. The apparatus includes a pair of work stations, each including a fixture for receiving an empty toner cartridge and a guide for supporting a seal insertion tool into predetermined juxtaposition with that cartridge. A motorized actuator extends each seal insertion tool into juxtaposition with the toner cartridge, and retracts that tool from the cartridge after sealing is completed. Powered clamps engage the toner cartridge to assure positive contact between the cartridge and the seal. A single heater power supply is selectively connected to the seal insertion tools of each work station. A programmed logic controller performs the sequence of resealing operations for each work station, once initiated by an operator, so that the operator may then prepare the other work station for a resealing operation.
