Abstract

PURPOSE: To let winding of film be done extremely accurately by providing a member for guiding the leading end small-width part of the film downward and making use of the difference in friction force after the leading end of the film contacts the winding member.
CONSTITUTION: A film is unrolled by every fixed length by a sprocket and its leading end small-width part A is wound to the winding member 9 composed of high friction material by way of the rubber roller 29 of an acception pressure means 11 and the roller 24 of a superposing pressure means 10. Here, a guide part 25 is provided to the means 10 and a large-diameter part 13a is provided to the lower part of the member 9. As a result of this, the small-width part A is so force advanced downward as to direct to the straight line track. Since the friction force of the member 9 is larger than that of the roller 29, the advancing speed of the inner film becomes higher than the speed of the succeeding film 4 and the small-width part A turning around the member 9 makes gradually closer contact with the outside peripheral surface. Thereby, the winding of the film may be performed extremely accurately.
