Title: Shaping tubes of thermoplastic resin - by pressing against mould interior with pressurised medium supplied by internal pipe
Inventor: PERNSTEINER MAXIMILIAN DIPL KF
IPC: B29C48/09
Filed: 1975-10-03
Abstract: Tubes of thermally deformable matl., esp. a thermoplastic resin, are continuously shaped by introducing a pressurised medium, esp. compressed air, into the deformable tube, so that the tube is pressed against the inside of a hollow mould. The pressurised medium is introduced by a pipe that can be inserted into the hollow mould as the latter moves together with the moving tube. The shaping operation is started by inserting the pipe through the hollow mould, and then displacing the deformable tube over the end of the pipe situated in the initial region of the hollow mould. The mould is then set into movement corresp. to the movement of the mould, and pressurised medium is introduced into the tube. Method provides continuous, accurate shaping of the tube, e.g. as the tube leaves an extruder, using a relatively small amt. of pressurised medium. Method gives shaped tubes with a smooth surface with no damage to the mould during shaping.
