Abstract
PURPOSE: In an apparatus where after a predetermined length of film is rolled round a bobbin, the bobbin is rotated and moved to be replaced with an unloaded bobbin, to automatically adjust a gap between the outer peripheral surface of the rolled film and an adjacent roll to be at a fixed value.
CONSTITUTION: A bobbin 1 for taking up a film 1 sent forth from an extruding machine is adapted to turn in a circular arc round a fulcrum O and moved, when a predetermined length of film is rolled round it and reaches the full amount, to be replaced with an unloaded bobbin 3. At this time, a diameter of rolled film, which gradually becomes larger, is computed by each output of a speed detector 7 for detecting a running speed of a film 2 and a detector 8 for detecting the number of rotations of the bobbin 1, and a rotating position on an circular arc where the bobbin 1 moves from a position of starting taking-up a film is detected. A motor 13 for rotating a bobbin is controlled according to two signals of the roll diameter and the rotating position, so that a gap G between an adjacent roll 4 and the bobbin 1 is kept at a fixed distance.
