To position and bond together a preceding strip-like film and a succeeding strip-like film easily and with improved operational performance, pairs of front and rear clamp members (27,32; 28,33) are arranged on a running path of a strip-like film (F1,F2). A preceding film (F1) clamped by these clamp members is cut by a cutter (49). The rear clamp (33) only is then released, and a portion of the preceding film (F1) backward from a cut position (C) is removed. A succeeding film (F2) is moved forwardly until the succeeding film (F2) comes in contact with the front clamp member (32) whereby the succeeding film (F2) can be positioned in respect of the preceding film (F1). The succeeding film (F2) is clamped again by the rear clamp (33), electricity is conducted to a heater (45) under this state whereby overlapped portions of the two films (F1,F2) are bonded. Thereafter the two clamps (32,33) are released and the running of the bonded film is restarted. <IMAGE> |
