Abstract

PURPOSE: A device for making nodes on resin-covered pipes in which a flexible or shrinkable path is connected between the extruder and the crosshead die and simultaneously the crosshead die is moved and stopped, thus forming one pair of ring ribs at the prescribed positions on the pipe surface.
CONSTITUTION: Pipe A to be coated is set into the guide path of crosshead die 4 and continuously sent in the direction shown by arrow a at a prescribed speed, covered with resin B sent from the extruder through the intermediate path made of shrinkable pipe joint. Cam 65 rotates in the direction shown by arrow b and when cam follower 62 comes into contact with cam surface 651, bar 61 along with die 4 advance by a certain distance in the same direction at the same speed as those of pipe A, whereby the relative covering speed becomes zero and ring rib B1 is formed. After die 4, which has come into contact with cam surface 652, stops at a time, it advances again whereby the second ring rib B2 is formed. Then die 4 goes back by contacting with surface 654 of cam whose diameter gradually becomes smaller until it stops by contacting with cam surface 655. Meanwhile parallel part B0 is formed.
