Title: Preparation of synthetic resin sheet
Inventor: YAMANE YASUAKI
IPC: B29K27/06
Filed: 1985-07-12
Abstract: PURPOSE:To prevent a synthetic resin sheet from the generation of slackening and wrinkles even if said sheet is exposed to high temp., by stretching the synthetic resin sheet to the lateral direction thereof within an elastic limit and contracting the width of the sheet after stretching to the width almost same to that before stretching. CONSTITUTION:A sheet 1 is passed through an embossing apparatus 8 and guided by a guide roll 12 to be sent to a stretching apparatus and stretched to the lateral direction within the elastic limit thereof. The stretching ratio at this time is set so that the width of the sheet is made wider by about 27-38% than that thereof before stretching. The temp. of the sheet immediately before stretching is 40-100 deg.C and lowered by 3-5 deg.C during stretching and the sheet after the passage through the stretching apparatus 3 is shrunk by the natural shrinkage of the sheet 1 itself so as to have a width 0-3% wider than that before stretching. As mentioned above, by again shrinking the sheet after stretching, the sheet is shrunk in both directions and, therefore, slackening and wrinkle do not appear even if said sheet is exposed to high temp.
