ABSTRACT:
A one-piece clip of flexible metallic plastic material has a first section which can be separably affixed to a belt conveyor, and an elongated slotted second section. A web of photosensitive material is caused to extend through the slot of the second section so that its leader is located at one side and the next-following portion of the web is located at the other side of the slot. The leader is then folded against the respective major surface of the second section, and the web is form-lockingly connected to the second section. The form-locking connection can be established by one or more pairs of complementary tooth-shaped protuberances which extend into the slot and penetrate into and through the folded portion of the web behind the leader, by securing the leader to the next-following portion of the web by a clamp in an enlarged window-like portion of the slot, or by bonding a small part of the leader to the next-following portion of the web in such window-like portion of the slot.
