IPC: B29C55/06
Filed: 2002-04-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a film stretching method which minimizes the incidence of a necking problem, the solution of which is insufficient by a conventional roll stretching technique, in view of the fact that the necking phenomenon ensuing from a longitudinal stretching process reduces the width of a film and causes an increased thickness on both end parts of the film affected by the necking phenomenon and therefore, both end parts are trimmed to save the film as a finished product but unavoidably with a significant yield deterioration, and a stretching device used for this method.  <P>SOLUTION: This longitudinal stretching device is equipped with a film heating mechanism, a film feed mechanism and a film take-up mechanism which takes up the film at a higher speed than the film feed mechanism. The described problem is solved by arranging the film cooling mechanism between the film feed mechanism and the film take-up mechanism.  <P>COPYRIGHT: (C)2004,JPO
