Abstract

PURPOSE: To enable continuous production of laterally stretched web, by a method wherein cutter tips of a cutter stand, having a large number of cutters positioned at a given interval in a longitudinal direction of a running film, are pierced through the running film momentarily.
CONSTITUTION: The film is run between a cutter stand 3' in which a large number of cutters in the lateral straight line or intermittent shape are arranged in series or in parallel in the longitudinal direction of the running film at given intervals, and a cutter receiving stand 7 having slits 9 whereinto cutter tips of the cutter stand 3' are inserted when the cutter stand 3' comes in proximity to the receiving stand 7. Either one of the cutter stand 3' and the receiving stand 7 is intermittently rapidly moved in proximity to their respective opposite stand to pierce the cutter tips to cut the film laterally. Both side edges of the film are held and with this the film is stretched laterally under such a state as heats the film to continuously produce film laterally stretched webs.
