Abstract

758,804. Moulding collapsible tubes &c. SLAUGHTER, C. E. Oct. 22, 1954 [Oct. 22, 1953], No. 30516/54. Class 87(2) A hot slug 1 of polyethylene, polyvinylidene chloride or nylon is clamped between a plate 2 and spring- pressed plate 4. A mandrel 9 is then moved downwardly to stretch the material into the form of a tube, a disc 14 on the mandrel shaping the end of the tube and preventing the walls of the tube from touching the mandrel, and thus preventing the walls of the tube from being cooled. When a small part of the tube has been formed, the tube is engaged by a metal die 24 which shapes the end of the tube and due to its contact with the metal causes it to set in its moulded shape. The plastic material is forced into the desired shape, which may include a screw-thread, by means of a piston 27 in the die 24. The mandrel 9 is then lowered further to form a tube of the desired length. A tube 34 is then raised, the open end of the tube blocked and air blown into the tube through a hole 37 to blow the tube into contact with the tube 34 and to set the tube in its finished shape. The tube 37 is then dropped, the die 24 removed, by unscrewing, if it is.made in one piece, and the finished tube severed at its open end from the remains of the slug. A pin 38 on the piston 27 may punch a hole in the neck 32 of the tube (Fig. 5, not shown).
