Title: Operating rotating traveller rings of ring - spinner
Inventor: FUERST STEFAN
IPC: D01H7/58

Title: Continuous blow moulding sequence - with accelerated transfer of mould to extruder position
Inventor: FROHN WALTER DR ING
IPC: B29C49/36
Filed: 1972-04-12
Abstract: In the parent patent a method of making blown plastics hollow objects consists of passing a number of blowing moulds in succession past an extruder head, where each receives a section of extruded tube, and a blowing head where this rough is blown; a continuously running driver moves all the blow moulds. As each mould approaches the extruder position it is disconnected from the driver and is accelerated away from the succeeding blowing mould, then is arrested at the extruder to receive the extruded length of tube. In this patent as the blow mould approaches the extruder head it is simultaneously uncoupled from the driver and coupled to an accelerated driver which conveys it rapidly to the extruder position; here it is picked up again by the first driver when the driver arrives there.

Title: Pre-heating particulate plastics in hopper - with air warmed by extruder waste heat
Inventor: RIEDEL ERICH
IPC: B29C48/793
Filed: 1974-01-24
Abstract: A device for pre-heating pulverulent or granular plastics is fitted with a hopper connected to an extruder and provided with a line for feeding a heating medium. The line is connected with a suction hood which covers that part of the extruder subject to heat loss during operation. The heat-losing part of the extruder has coiled piping connected to the coils of a heat-exchanger through which an air stream generated by a ventilator passes. This air stream is thereby heated and enters the hopper via the line. Waste heat from the extruder is used to pre-heat the plastics. The air which sheds its heat in the hoppers and issues therefrom at a reduced temp. may be used to cool the workshop, thereby helping to improve working conditions.
