METHOD TO PRODUCE THERMOPLAST BARRELS WITH GROOVED LIDS, CASTING THERMOPLAST WIDE-NECK BARRELS AND APPARATUSES FOR THEIR PRODUCTION Russian patent published in 1995 - IPC

FIELD: tare production SUBSTANCE: after separation, produced bodies and cast lids are cooled on pattern mould on sites of cooling and calibrating. The sites are located after machine for formation by inflation of bodies of double barrels and machine for barrel lids casting under pressure. Then welding of grooved lids with bodies is exercised. In process of wide-neck barrels production after barrels and lids are cooled on pattern mould hardening mass of polymeric material is injected into lids are lids put on barrels bodies and press them together with the help of shell. Apparatus to produce barrels with grooved lids has site of barrels and lids calibration and cooling, casting machine, lids edges cutting off machine, welding machine. Apparatus to produce wide-neck barrels instead of machine has hardening mass injection machine. EFFECT: method and apparatuses are used to produce tare. 9 cl, 4 dwg
