Abstract

Pipes are produced by helically winding a warm, extruded plastics strip onto a number of tapes movable axially of the spindle, and rotating with the spindle. Pipes of require, required elasticity and flexibility can be produced at a high production rate. Appts. includes a rotary spindle provide with a peripheral array of endless tapes passed over one end of the spindle and a guide roller, whereby the extruded strip is laid in an abutting relationship by means of a guide roller.
