Apparatus for handling melted glass

摘要

Apparatus for extruding glass (30) from an orifice (31) at the base of a feeder by means of a vertically reciprocating plunger (4) in order to enable glass gobs to be formed (for subsequent moulding into glass objects such as containers) is described. According to the invention, the vertically reciprocating motion of the plunger (4) is generated by means of a linear motor (8) having an actuation member which moves in order to move the plunger (4) correspondingly. The actuation member may bear on the underside of a bridge piece (3) mounted for vertical movement up and down on an appropriate guide structure, the end of the bridge (3) remote from the motor and guide structure having the top end of the plunger (4) fixed to it.
