Author Topic: Christie wrap detector? Ken Lackner Phenomenal Film Handler Posts: 1907 From: Atlanta, GA, USA Registered: Sep 2001 posted 04-20-2005 08:31 PM                     In the closeup of the AW3 from the Vasity Theatre pictures there appears to be some sort of brain-wrap detector installed at the top of the platter tree. I have never seen this on a Christie platter before. Is that what that is, or am I seeing wrong?  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 04-20-2005 09:24 PM                     Yeppers, it's a Strong wrap detector adapted to fit on the AW3 unit. It uses a bracket arm that is attached to the tower then the swivel bracket is attached to this arm and then the the wrap detector is attached to that arm. This wrap detector being on a swivel, allows for lateral motion for film travel, and there is a tension thumb screw that adjusts the failsafe roller tension from a hair trigger action to a delayed action. I usually take off that thumb screw to keep the system safe due to immediate shutdown. The detector is wired in series with the failsafe so that either one opens will dump the system. The actual Christie wrap detector is the 196270-001 wrap detector that replaces the lower roller assembly on the AW3(r) units, and is wired the same-in series with the failsafe. -Monte  |  IP: Logged Ken Lackner Phenomenal Film Handler Posts: 1907 From: Atlanta, GA, USA Registered: Sep 2001 posted 04-20-2005 09:58 PM                     Yeah, that does look like the Strong detector. That's what I thought it was. Regarding the Christie detector you mentioned, I didn't know they even had one. I've never seen one, and I've seen a lot of Christie platters. I wonder why they're not more popular.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 04-20-2005 10:08 PM                     the Strong unit is the 2468153 and lists from the catalog at $351.00. I don't know what the price for the Christie is, but your supplier can find that out for you. Prob why the Christie isn't as popular due to the quality of Christie (even though I've had many a wraps due to "poly" film and AW3r's and wish that I had a wrap detector back then), or no one knows about it. -thx Monte  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-20-2005 10:45 PM                     Actually if you have a Strong or Potts(and pans)platter system you don't need to buy a wrap detector. Add another roller on a piece of flat alumnium stock bent to the correct angles to the slide tree on the back of the column. Skip threading the outgoing film over the lower column outgoing roller and thread it over that added roller you just mounted on the slider. If you end up with a wrap it will cause the slider assy to climb higher and shut down the platter. Take up effectively stops and down goes the failsafe arms and a shut down occurs. This is a poormans version but I have done many of these and they work really well. Cost is less than 20 bucks for another guidance roller assy. Static problems are alot less today than they were a few years ago thanks to John P.!

I have never actually seen one, so it didn't stick out in my mind.
