    摘要： A vertical format corrugator or the like tube producing apparatus has two sets of independent mold sections (16) that circulate on respective paths. The mold sections (16) co-operatte to define a travelling mold cavity (18) into which a thermoplastic tube may be extruded to be molded. Fixed tracks extend along the forward and return runs of the mold section paths and are engaged by track followers on the mold sections (16). The track followers support and guide the mold section, thus enabling the elimination of chains linking the mold sections (16). In preferred embodiments, transfer mechanisms are provided at the ends of the runs to transfer the mold sections individually from one run to the next. The mold sections (16) may include removable mold blocks, means for automatically changing the configuration of the mold cavity (18) and a system for internal cooling of the mold sections (16).

    摘要： In an apparatus for producing multi-walled thermoplastic tubing in which the inner and outer tubing walls (33 and 26 respectively) are continuously formed by extrusion one within the other, the inner tube (33) being urged outwardly into pressing engagement with the outer tube (26), the mechanism for urging the inner tube outwardly into securement with the outer tube comprises a mandrel (70) mounted coaxially with the die (25) for extruding the inner tube and on the downstream side of it. The mandrel has an outer surface providing a tapered end portion (72) positioned to receive the inner tube as it is extruded, and a generally cylindrical portion (71) positoned to urge the inner tube into securement with the outer tube. To prevent sticking of the thermoplastic material to the mandrel, the outer surface of the mandrel is maintained at a temperature lower than the molding temperature and is transversely ribbed (73).

    摘要： The invention provides a die assembly comprising a nozzle (11) and at least one mandrel (24) which defines with the nozzle an annular die orifice. The nozzle has a longitudinally extending stem (18) terminating in the sleeve (25), the mandrel (24) being located coaxially within the sleeve (25) and coupled to the stem (18) of the nozzle (11) by an axially extending screw threaded coupling. The mandrel includes an internal flow passage (36) having an inlet positioned to receive thermoplastic material from a supply passage (36) extending along the nozzle (11) and an outlet (37) positioned to deliver the material to an annular distribution chamber (27) defined by the opposing surfaces of the mandrel (24) and the sleeve (25). The distribution chamber (27) provides an uninterrupted annular flow path extending from the outlet (37) to the die orifice, thereby avoiding the disadvantage of imperfect material distribution. For the production of multiple-walled tubing, a plurality of die stages coupled together in coaxial relationships are provided, the die components being so coupled by axially extending screw threaded couplings so positioned as not to interfere with the flow of plastic materials.

    摘要： Corrugated pipe sections (10 and 11) are coupled end to end by shrinking a heat shrinkable sleeve (12) into close gripping frictional engagement with the end portions of the pipe sections (10 and 11). The sleeve (12) conforms to the corrugated surfaces of the pipe sections (10 and 11) thereof providing a sound mechanical interlock, and an auxiliary sleeve (13) of relatively hard thermoplastic material is used to resist shearing forces. A sealing ring 17 is provided at the join.

    摘要： In an appartus for producing multi-walled thermoplastic tubing (26,27) in which the inner (27) and outer (26) tubing walls are continously formed by extrusion one within the other, the inner tube (27) being urged outwardly into pressing engagement with the outer tube (26), the mechanIsm for urging the inner tube (27) outwardly into securement with the outer tube comprises a shuttle (36) mounted on a longitudinal guide (34) and having an expansible wall (37). The shutter (36) is reciprocated between first and second limit positions (42,58), the expansible wall (37) thereof being alternately expanded and collapsed in response to the arrival of the shuttle at its limit positions (42,48). By this means, a more effective joint between the inner (27) and outer (26) walls of the tubing (26,27) is achieved.
