Document Type and Number:
Japanese Patent JP3990753
Kind Code:
B2
Abstract:
Profiled thermoplastic pipes are made in mould half sections (4,5) attached to an extruder (7). The mould half sections (4,5) move in pairs along a track (2) to form a closed moving mould. At the downstream end (70) of the track (2) the sections are moved across the prodn. direction (6) by a transport device (29) and returned to the upstream end (67) for reuse. The transport device (29) is in the shape of a gantry crane with a gantry (34) spanning the track (2) and able to move in the prodn. direction (6). The gantry (34) supports two carriages which can travel at right angles to the prodn. direction (6) opposite to each other and have a support arm pointing towards the base (1), each carrying one mould half section (4,5).
