CHR AW3(r)'s with that rewind roller arm (which is spring loaded) makes a good accumuator roller for interlock systems when your tying two AW3's together for one print usage.

You just turn off that deck when using that arm for such.

Be nice if the Strong's "W", "yo-yo", etc. DID have some resistance to that assembly so when mistarts happen, that this device racing up doesn't bust up the leader before one has a chance to stop the "rewind" platter, especially with the platter situated at the "gear side" of the projector.

quote: Brad Miller
unlike running reel to reel with a conventional clutch
Simplex XL magazines(and even Cinemeccanica) had the neatest takeup clutch design: the constant tension clutch. Using that "cone and drum" concept in keeping the tension constant whether the reel was empty, or getting full. And with the Cinemeccanica V-18's 13k reels, it worked pretty slick, as long as one kept an eye on the adjustment end of the operation.

Actually the Tecco reel arms had a spring loaded roller on them
