Hi:
I've searched a bit about tight/even rewind but couldn't really find explicitly detailed instructions on how to do this. We have a Kelmar 7900 rewind bench. We rewind generally at about 35/100 speed onto cores when we receive them, but they're still telescoping. One thing i thought is that we need to tighten the drag on the left spindle to increase the tension.
I do find that take-up onto a good shipping reel produces the best wind, but have always been told never to use split reels on the projectors. and only in a certain orientation on the rewind bench. My understanding is that the concern was about the split reel unscrewing. Seeing that Brad says it's okay to use a split reel as take-up gives me confidence that this would be okay to do.
But, on a rewind bench, if the split reel is on the left spindle it actually spins counter clock-wise (which I would think would cause it to unscrew if that in fact is a problem). That said, the split reel on the right spindle (i.e the same as the take-up) would be a clockwise turn.
So, I have a couple questions:
Would tightening the tension on the left spindle on the rewind bench help? How do you know when is too much tension? Or should I use the automatic arm?
Is it really safe to take-up cores using split reels? We have a Simplex XL but that really doesn't say anything about the feed/take-up arms.
Is it ever a bad idea to take-up onto shipping reels, if they're in good shape?
Do split reels indeed unscrew accidentally on a spindle? (other than when a human unscrews them)
If they do unscrew, why? We have 2 split reels, both have a longer post, but one has the female end and the other a male end on the longer post.
Do they unscrew b/c of the direction of spin (i.e. as I said above, if on the left spindle, rewinding under to over, the left spindle is turning counter clock wise. or do they unscrew b/c of whether the longer post in engaged on the rewind table.
Sorry for the long post but I'm trying to be as clear as possible.
Thanks for any help!
