摘要:
Formable twistless woven precursor fabrics, especially in satin or basket weave, made from flat tape of fiber reinforced thermoplastics on a power driven loom (10). The weft tape (18) is supplied from a rotatable package (19) that is driven in synchronism with the feeding mechanism and a finite tension on the tape is maintained.
摘要:
A fiber reinforced material is made by passing a preheated tensioned filament array (10) over an arcuate extruder head (20) where thermoplastic polymer is flowed through the filament array to expel air from the array while coating the filaments with polymer. The filaments comprise 50 to 75 percent by volume of the material and the polymer has a relative viscosity of at least 50.

摘要:
A yarn finish applicator in which finish is metered to a slot running from top to bottom of the applicator. The configuration of the body of the applicator and its slot provides an edge (17) at the exit end of the applicator and a slot (20) that is slightly wider at the location (30) at which finish is metered to the slot than at exit of the slot. Two rods (32, 34) are located just below the exit edge (17) of the applicator to collect and drain to a receiver any drops of excess finish which form at the exit edge of the applicator when the threadline is not running.
