Abstract:
1. A method for bonding a dry fiber strip to a single dry fiber strand, in an axial direction and in continuous, uninterrupted operation, by way of a bonding agent that is activatable by supplying heat being provided on the fiber strip, with the fiber strand having a three dimensional cross section and at least one flat mantle surface, comprising: unwinding the fiber strip and the fiber strand from respective supply rolls, fixing the fiber strip on a conveyor belt using suction, positioning the flat mantle surface of the fiber strand on the fiber strip during the unwinding procedure, unwinding an air-impermeable film from a supply roll, covering the fiber strip and the fiber strand positioned thereon using said air-impermeable film in a suction area so as to improve an effect of the suction used to fix the fiber strip on the conveyor belt, supplying heat to the air-impermeable film, the fiber strip, and the fiber strand in a heating area using hot air blowers to cause activation of the binding agent and gluing of the fiber strip and the fiber strand, and receiving the air-impermeable film on a rollup roll disposed in a location after said heating area.
