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.

Abstract: The insertion of thread into a yarn tester is accomplished by a mechanism that includes a clamp (3) for the thread end and an insertion arm (14) mounted for pivoting movement about a fixed axis to contact a portion of the thread above the clamp and swing a loop portion of the thread down into the space between feed rollers and to present the loop to a take-over nozzle (13). The thread is transferred from the insertion arm to the nozzle (13) and is fixed until transfer in the clamp (3), so that the thread transfer takes place in the form of a loop. Consequently, the insertion arm (14) need have no special thread clamp and can be of correspondingly simple design. The pivoting movement of the insertion arm (14) requires only a simple drive, and the take-over of the loop-shaped thread (F) by the take-over member is carried out without difficulty.

If the threader is to be used with a relatively wide web, two spaced apart belts are preferably provided and connected threader bar to which the web is attached. An electronic control system monitors operation of the threader assembly and terminates operation of the threader assembly upon breakage or jamming of the web or the belt.

Abstract: The tape threading mechanism threads a magnetic tape from a magnetic tape cartridge along a tape transport path to a take-up reel by using a two-member, spring loaded tape threading arm which uses two cam surfaces to control the articulation of the spring-loaded tape threading arm. A cam follower formed on the upper end of a leader block locating pin of the tape threading arm engages a short cam surface at the beginning of the tape transport path to guide the leader block of the magnetic tape along a short distance at which time the tape threading arm is smoothly accelerating. Once the cam follower disengages from the cam surface, the spring-loaded tape threading arm is locked into a fixed radius which allows the magnetic tape to maintain a constant velocity through approximately three hundred degrees of rotation, at which time the cam follower engages a second cam surface. The second cam surface guides the cam follower and leader block into position to engage the take-up reel.
