Abstract: A method of dispensing a strip product using a strip fabrication assembly, by entering arm positions for guide arms of the assembly into a guide arm controller device, moving the corresponding guide arms of the strip fabrication assembly to the respective arm positions using the guide arm controller device, and feeding different strip materials through the assembly using the guide arms, after moving them to the entered arm positions. The guide arms are coupled to threaded rods, and are moved by actuating servo motors which are coupled to the threaded rods. The guide arm controller device may include a programmable logic controller, which has been programmed to control the servo motors in response to entry of guide arm positions.

The composition is effective for use in the transportation industry, the building industry, the aerospace industry and the appliance industry.
Abstract: The present invention relates to a hot melt moisture cure adhesive composition well suited for bonding porous substrates such as fabric, methods of adhesively bonding substrates and corresponding articles. The adhesive composition exhibits a combination of flexibility, high green strength, low molten viscosity and high heat resistance. In view of these properties, the adhesive is particularly amendable to hot melt adhesive application techniques wherein small individual discrete deposits of adhesive are applied to a substrate. The adhesive composition prepolymer is preferably the reaction product of at least one polyol, at least one polyisocyanate and at least one high molecular weight thermoplastic polyurethane lacking hard segments.
