    摘要： Apparatus for making profiled plastics tube and comprising two circulating endless chains, each making a plurality of mould halves (18) move along with the tube (2) coming from an extruder (1), these mould halves pairwise constituting a mould cavity in which the tube is being given its profile. According to the invention the moulds (18) are movable relative to the chain links (1, 2) in a direction perpendicular to the direction of movement (P) of the links. The machine frame is provided with guides (33, 35, 37) for the moulds, some located interiorly, others exteriorly, with respect to the chain loop, such that once closed, the cavity formed by the pairs of mould halves will remain closed and undisturbed up to the end. Preferably the transitions (41, 42) between curved portions (36,43) and the operative portion (32) of the path (31) of the moulds at the entrance and the exit ends are bending points of mathematically calculated paths and the operative straight path tangentially joins said transitional portions. In order to further eliminate vibrations and other disturbances in the regular course of the moulds it is preferable that the chains (46) are each provided with driving means (40) which are operative near the entrance end of the operative straight portion (32) of the path, and with braking means (44, 59-63) which are operative near the exit end thereof.

    摘要： A compression moulding machine comprises a series of moulds 1 fed with moulding material from a hopper 11. Preheating chambers 8, 9 and 10 corresponding to the moulds are disposed between the hopper and the moulds into which moulding material from the hopper may be fed. Material so fed is heated in the chambers 8, 9 and 10 by heaters 23 before being discharged into the moulds 1. This shortens the curing time of material in the mould, thus increasing the efficiency of the moulding process, without increasing the risk of damage to moulds or hopper due to preheating of the material in the hopper.
