Title: Mfr. of mouldings of partially-crystalline polymer e.g. polypropylene@ - by in=line thermo-forming, by cooling extruded web under tension and then temp.-equalising under negligible stress
Inventor: HARTNAGEL HATTO DIPL ING
IPC: B29C51/04
Filed: 1991-05-18
Abstract: Process and appts. for mfr. of mouldings of partially-crystalline thermoplastics by in-line thermoforming. The extruded web is cooled under tension, then temp.-equalised under negligible stress to the temp. required for thermoforming. Process comprises:- (a) web melt extruding from screw extruder and wide slit die; (b) web cooling and polishing by roll stack. c) Web tensioning by haul-off rolls running 3 to 10 per cent faster than roll stack, while air cooling (Stage "A"); (d) web then falls under self-weight, otherwise stress-free, to dancer roll (Stage "B"). Steps a) to d) are continuous; (e) web edges then are perforated by needle-chain and carried upwards under no stress and to thermoformer (Stage "C"); (f) chain then carries web through thermoformer (Stage "D"). Steps e) and f) are intermittent, to suit thermoformer. In Stage A, the web is cooled to 160 deg.C. (for PP) at the centre and 140 deg.C. at the thin surface layers, which are strengthened for handling by cooling, orientation and crystallisation. In Stage B, the web equalises in temp., raising the surfaces to say 155 deg.C., nearly that of the centre and above the range of rapid crystallisation. In Stage C at approximately uniform and constant temp., the amorphous web is held laterally by the needle-chains, but tends to shrink (SIC), giving biaxial orientation in the surfaces, advantageous for stability in thermoforming. The dancer roll may be driven by two vertical endless chains, a) continuously driven by nip roll b) intermittently driven by conveyor shaft to move down and up for the web travel and the thermoformer feed, respectively. With the above, nip roll may be 2 to 10 per cent larger than dancer roll to ensure no stress in web. USE/ADVANTAGE - Thin-walled mouldings, e.g. beaker-shaped containers for milk products, from esp. polyolefins, e.g. polypropylene. Reliable process, redn. of waste and essentially amorphous mouldings.
