Abstract
A heated polymeric sheet material feeding process. The process may include heating a polymeric sheet in a heating zone to a forming temperature to form a heated polymeric sheet material. The process may further include transferring, while under a feeding vacuum range, the heated polymeric sheet from the heating zone to feed the heated polymeric sheet material into a forming zone under the feeding vacuum range.
Claims11
A polymeric sheet material forming process comprising:
- heating, while under a heating vacuum range, a first polymeric sheet in a first heating zone to a first forming temperature to form a first heated polymeric sheet material;
- and
- transferring, while under a feeding vacuum range, the first heated polymeric sheet material from the first heating zone to feed the first heated polymeric sheet material into a forming zone under the feeding vacuum range;
- forming, in the forming zone, the first heated polymeric sheet material into a first formed article;
- heating, while under the heating vacuum range, a second polymeric sheet in a second heating zone to a second forming temperature to form a second heated polymeric sheet material, the first and second heating zones are different;
- after the first shaped article exits the forming zone, transferring, while under the feeding vacuum range, the second heated polymeric sheet material from the second heating zone to feed the second heated polymeric sheet material into the forming zone under the feeding vacuum range;
- and
- forming, in the forming zone, the second heated polymeric sheet material into a second formed article.
