Abstract
In the production of a glass vessel (such as a goblet) comprising a receptacle part (e.g. a goblet bowl) and a stand part (e.g. a stem with a base plate), the receptacle part is formed by pressing in successive moulds carried by a rotary table and the stand part is formed by injection moulding, being simultaneously united to the receptacle part. In carrying the invention into effect the mould for the receptacle part is charged from a feeder in free drop fall; the table is then rotated to bring the pressed receptacle part into register with an injection mould for the stand part, and an injection device, of which the injection mould forms part, is charged from the same feeder by way of a drop guide channel.
Claims9
A method of producing a glass vessel consisting of a receptacle part and a stand part, in which the receptacle part is produced on a rotary table in a pressing operation and subsequently the stand part is formed by an injection device and in so doing is united with the receptacle part, characterised in that a mould for the receptacle part is charged in free drop fall by a glass feeder, and in that the receptacle part, after pressing and cooling, is transposed onto an injection mould for the stand part, which injection mould is integrated into the rotary table for the receptacle part, and in that the injection device for the stand part is charged from the glass feeder by way of a drop guide channel.
Apparatus for producing a glass vessel consisting of a receptacle part and a stand part, comprising a rotary table having press moulds, adapted to be charged in free drop fall from a glass feeder, for the production of the receptacle parts, characterised in that injection moulds for the stand parts are arranged on the rotary table beside the press moulds for the receptacle parts, and in that at least two collecting vessels are provided in the region of a feed station, each said collecting vessels having an injection plunger, which plungers are coupled to one another and can be swung under the successive injection moulds after charging with injection-mould glass gobs.
