Abstract:
PCT No. PCT/EP91/00581 Sec. 371 Date Nov. 25, 1991 Sec. 102(e) Date Nov. 25, 1991 PCT Filed Mar. 26, 1991 PCT Pub. No. WO91/15349 PCT Pub. Date Oct. 17, 1991.The invention relates to an apparatus for the production of tubes from prefinished pipe elements, by pressing cf a tube head from a heated blank (24) of a plastic, with simultaneous bonding of the latter to the tube pipe (13), with an indexed transport means which stops at several work stations (II-VII) arranged at equal distances from one another, with mandrels (7) that travel along to hold the pipe elements (13) and dies (5) arranged coaxial to the mandrels (7), which also travel along, and have central hole punches (21''), if necesary, where the mandrels (7) can be axially moved and are arranged to work together with a press (8) in such a way that they can be inserted into the dies (5) to press the tube head, as well as with a loading and unloading station (I, VIII) and with an extruder (12) and a metering device (11). According to the invention, the mandrels (7) are arranged so that in addition to the coaxial position relative to the dies ( 5), they can be moved into parallel positions relative to that position, where preferably the mandrels (7) can be moved to at least one inner and/or one outer additional orbit (A, C) parallel to the orbit (B) of the dies (5), located outside the transport means.
