On the Rolling of Thermoplastic Sheet

Abstract

The rolling of thermoplastic sheet at the plastic flow temperature seems to be different from the rolling of metal because the elastic after-effect of thermoplastic is very remarkable. However, according to the experimental result of compression of the sheet, indentation by roll into the sheet and rolling of the sheet of rigid polyvinyl chloride, the rolling theory which is utilized in metal working can be also applied to the rolling of thermoplastic sheet if the elastic after-effect is evaluated. This paper shows that the necessary data on the elastic after-effect can be obtained from the tension test.
