Title: Apparatus for producing containers from mouldable material
Inventor: STROOP JOHN HENRY

Abstract: 1,170,080. Blow-moulding. J. H. STROOP. 7 Dec., 1966 [17 Dec., 1965], No. 54867/66. Heading B5A. [Also in Division B8] In apparatus in which sheets of material are blow moulded to form containers, pairs of mould halves are mounted for horizontal slidable movement towards and away from each other on a vertically reciprocable platen. In the embodiment shown, four pairs of mould halves such as 54, 55 are mounted side by side on the platen 30 which reciprocates in channels 21 under the action of crank mechanism 34. During upward movement of the platen, cam followers 58, 59 on the mould halves, follow the outside profile of cams 22, 23 respectively to separate the mould halves which slide along pins 65, and during downward movement of the platen the followers engage the inner profiles of the cams to close up the moulds. Sheeting of plastics or metal foil or a combination of the two drawn from reels 70, 71 is fed over heated drums 74, 75 into the moulds on each side of a tube 78 having concentric passages (79), (80), Fig. 5 (not shown). Air, blown through the outer passage (80), forces the sheets against the moulds and causes them to seal together to form the container. Upon reaching the bottom of the cams, the moulds separate and the tube is drawn out of the container. When the mould halves have risen and clamped over the sheeting to form the next container cutters (87) associated with heaters (85), Fig. 4, 6 respectively (not shown), carried in the bottom of the moulds, sever the formed container which falls and is diverted by a member 86 to be grouped as shown. Containers so formed are shown in Fig. 13 having a tear tab 93 for forming an opening. A cap (96), Fig. 11 (not shown), placed over the opening may affect a re-closure.

The transmitters 15, 16, Fig. 3, may be lightemissive diodes 17 in transmission pipes provided with apertures 18, and the receivers 19, 20, Fig. 4, may be provided with phototransistors 21. In Fig. 5, the position indicated by arrows B and C1 and the distance between transmitters 15, 16 and 28, 29 and the corresponding receivers 19, 20 and 36, 37 is equal to the distance between facing ends of links where no wear of the links is to be allowed without indication being given. The transmitters and receivers may however be re-positioned so that light is received at the same time by the receivers 19, 20 and 36, 37 when wear equal to the distance C1-C2 takes place. Other arrangements of transmitters and receivers are described and shown but the electronic equipment carried by the clamp 9 and shown in Fig. 9 comprises, connected to the receivers and transmitters, amplifiers and pulse formers (40 a -40 j ), and logic circuitry 41 for receiving and processing the pulses to produce an output if there is a worn out link and an output per passing link. The first output is treated by a monostable flip-flop, a driver and a shift-register, and the second output by an amplifier plus driver in such a way that after a given number of links have passed since the defective link an indication is produced which operates via an amplifier. The circuit also comprises a pulse former (variable length of pulse) and a driver, and a paint spray or other suitable arrangement 43 which after delay marks the defective link. A lamp or other signal indicates that such a marking has taken place.
