Abstract

918,140. Moulding packing tubes. HAUF, L. May 26, 1960 [May 28, 1959], No. 18661/60. Class 87(2). Packing tubes of thermoplastic material are made by mounting a prefabricated tubular body 4 over a mandrel 3, introducing a measured quantity of the material which has been rendered plastic by heating into the cavity 5 of the die 1 through the central nozzle 2 while or before the mandrel 3 is advanced into the cavity 5 so as to mould a head on to the adjacent rim 4a of the tubular body 4. Descent of mandrel 3 and the feeding of the material are effected so as to limit cooling of the material before it contacts the die and mandrel. A peripheral recess 6 is formed between the rim 4a and the adjacent mandrel 3 in order that the welding of the tube head to the body 4 is effected along a substantial length of the body. When the thermoplastic material is polyvinyl chloride, die 1 and mandrel 3 may advantageously be used as electrodes of a highfrequency heating device. This heating assists in the welding of the head to the rim 4a and may, if required, be used during the moulding of the head to compensate for the heat loss of the material when it contacts the die and mandrel. The process may also be used for the moulding of bottoms, for example flat bottoms, on packing tubes.
