Method and apparatus for making wound tubes. |
摘要 |
Wound plastic tubes (4) can be made in an economical manner by applying a reactive polyurethane composition (17) to a moving substrate (7) and allowing it to cure to form a strap (16) which directly thereafter is wound onto a cylinder (2) at a winding angle, the joint (22) produced between the windings (20) also being filled by casting with a reactive polyurethane composition (23), and the tube (4) produced as an endless strand being taken off continuously from the cylinder (2). <IMAGE> |
