Abstract

PURPOSE:To obtain a film, which has uniform molecular orientation and high dimensional stability by a method wherein the longitudinal shrinkage is preceded by the shrinkage in biaxial directions. CONSTITUTION:In a heat treatment zone F, the elimination of internal strain due to stretching and the control of degree of crystallization are done. In the heat treatment zone F, a shrinking zone J and a cooling zone K are provided. In the shrinking zone J, the width Y of a sheet-like material is gradually narrowed to the width Z and at the same time the pitch Pmax of clips 2 is guided by being controlled with guides 4, 5 and 6 so as to bend roller chains 19, resulting in turning the pitch of the clip 2 into Pi and also longitudinally shrinking the sheet-like material or shrinking simultaneously longitudinally and laterally. As a result, a highly functional film, in which the molecular orientations in longitudinal direction and in lateral direction of a sheet-like material are well balanced, can be manufactured.
