Hollow glassware made from gobs in multistation moulding machine - where parisons can be reheated before final blowing, esp. when mfg. bottles

摘要

The machine has several sections, each consisting of three statios (A,B,C) for (A) moulding a blank from a gob, (B) reheating the blank; and (C) final moulding of the blank. Transfer devices move the blank between stations (A-C) and then onto an exit plate; and the transfer devices used between stations (AB) and stations (BC) operate independently. The time between the releasing of the blank in station (B) and its clamping for transfer to station (C) is adjustable without influencing the basic cycle time which depends on the moulding cycles (B,C). The transfer of a blank from station (B) to station (C) is pref. synchronised with the transfer of the moulded prod. or bottle from station (C) onto the exit plate. The heating time used in station (B) is easily adjusted.
