take up reel doesn't
The film isn't being taken up by the back reel -- any film. It comes out but doesn't wind around the middle, just goes in and lies there straight. My projector is frigid! No seriously, what could be causing this?[/img]

If your take up reel is not rotating, it will not be able to take up the film. Depending on the projector make and model, this is probably due to a broken belt inside the projector. This can often be remedied by installing a new o-ring of the proper size to act as the take up belt. If the take-up reel rotates but the film doesn't automatically attach itself to the reel, you just need to help it. When enough film has exited the projector, stop the projector and place the end of the film on the take up reel and rotate the reel with your hand to satisfactorily load the reel. When you switch the projector back on, voila! I hope this helps you, projecting film can be a lot of fun. Good luck!

Successful auto threading depends on three factors:
1. The film. All film acquires a 'set' - it tends to curl one way or another depending on how it was stored. If the 'set' of your leader is such as to unwind from the feed reel, it will tend to bend away from the take-up reel and auto-threading will be difficult.
2. The reel. Most autothreading reels have narrow springs moulded into them to grip the film and cause it to run towards the centre. Once a bit more than a full turn is wrapped around the centre, the film will grip.
If the take-up reel is old, or has been badly stored, these springs may be distorted.
3. The projector. The angle at which the film emerges from the rear of the projector determines how it will hit the take-up reel and thus how weel this reel will auto thread.
The best projectors for auto-threading were the earlier Eumigs with the fingers that placed the film leader right onto the core of the reel. It is a pity they stopped this system. I think the Model S was the last one to have it.
