Abstract:
The invention relates to a process for the production of a tape comprising a plurality of impregnated continuous multifilament strands and a polymer sheath which intimately surrounds the plurality of impregnated continuous multifilament strands, wherein each of the plurality of impregnated multifilament strands extends in the longitudinal direction, wherein each of the plurality of impregnated continuous multifilament strands comprises at least one continuous glass multifilament strand, wherein the at least one continuous glass multifilament strand is impregnated with an impregnating agent, wherein the process comprising the steps of a) unwinding from a package the continuous glass multifilament strands, b) applying the impregnating agent to the continuous glass multifilament strands to form the plurality of impregnated continuous multifilament strands, c) placing the plurality of impregnated continuous multifilament strands in parallel alignment in the longitudinal direction and d) applying a sheath of a thermoplastic polymer composition around the plurality of impregnated continuous multifilament strands of step c) to form the tape, wherein steps c) and d) are performed in a die having a guiding means arranged for placing the plurality of impregnated continuous multifilament strands in parallel alignment in the longitudinal direction, wherein the plurality of impregnated continuous multifilament strands pass through a melt of the thermoplastic polymer composition inside of the die downstream of the guiding means.
