Abstract

See full text

Production line and method for manufacturing strips of foil stabilized plastics moldings featuring a rotary reform machine that has a pair of reform wheels that are rotatably driven to profile the extrudate while matching the output speed of extrudate exiting from the extrusion die of a plastics extruder. The wheels have equal diameters and are motor driven at the same angular velocity so that forming dies in the wheels synchronize and cooperate to pressure mold spaced sections of the extrudate feeding therethrough to form high quality end corners with an offal section therebetween. A haul-off pulls the strip from the extruder die, the rotary reform machine, a water trough and flash trimmer and into a cutter where the offal is removed. The strip is maintained under a predetermined tension load by use of an adjustable friction brake on the stabilizer foil so that the heated plastics exiting the extruder will be uniform in initial profile, providing high quality extrudate feeding into the reforming wheels.
