I did hear once a horror story on the Westrex Tower on rewinding the film, the operator had gone out for a minute as the film was rewinding and there was a almighty crash & bang, the spool on the spindle shaft had snapped off, sending the spool "Cart wheeling" round the Projection box smashing up the projector.

A very lucky projectionist to miss that happening!

My only real tower horror story like that was when I was breaking a print from the large reels (solid hub Golbergs) and as the first reel [of the feature] was coming off at high speed (Wolk rewinds with the speed control that has 2 speeds: off and 1725 RPM) as the reel came off of the make up table spindle and then CLANGGGG! ZING!!!!!!!!! One of the holes in the reel flange caught the 1/2" spindle, bending it 90 degrees straight up. The inertia of the spinning reel also sheared the rivets from one of the reels' flanges causing it to detach and become a buzz-saw as it headed first toward me, then toward the booth wall crashing to a halt within a second or two. Film, as you may have imagined, was everywhere, I was in shock for a few seconds and then had to face the reality of how in the hell I was going to bend that spindle back to use this table again. Yeeha! Fun!

Personally I think that the film when wound on a 48" reel is simply too heavy upon itself. Most locations that have towers that I have watched films in seem to have more than the average number of cinch marks. All in all, the films just seem to get beat up faster irregardles of the amount of care that the booth is getting.

As I said before, I do not have much experience with towers. Irregardless (ha Ha HA!) directly driving both reels with variable speed controlls seems like a logical solution--kindasorta like what is done with platters? And what about counterweights attached to the reels?

I have seen and used some of the Cinemeccancia "Floating Hub" spools, they have a larger spool hub with steel wire sides and do not seam to bend as with the old Premire 14,000ft spools.

The Westrex (5035 Film Carrier)Tower is controled by three variacs, one controls the pay off, the other for the take up. the third is for rewinding.

The Variacs control the current to the motors, and with the (Double Sided) can be four (two each side).

Mark, mentions 48” spools, which must be a horrendous size to handle. These would not fit the Westrex Tower as I know it, although I suppose it might be possible to raise the pay-off & take-off assemblies higher in the frame. The spools shown in the page 1 pictures are 36” diameter.

All,

My Tower 'horror' story is not really a horror story but its close. We were running a movie of a Cinemecanica tower system, and as the projector started (trailers on the other projector) for the changeover the film snapped at the bottom roller of the projector. Since there was two of us in the booth we decided in an instant not to stop. My mate went to the tower and started to reattach the film to the takeup reel while I took up position at the bottom of the projector making sure that the film fed out ok and didnt get looped or knot up (and tried to minimise the amount of film on the floor). Suffice to say after about 5 mins we caught up and kept the show on the sheet!. Ran it through the film cleaner afterwards and did a nice splice and all was ok. Try doing that with a platter!!!!

regards
Steve Brown

Hi there:

You asked if anyone was using Cinemeccanica machines with platters. I use 4 Victoria IVs and 3 Victoria 8s all with Strong platters (4 are the A3 model and 2 are the AP3). I like the Strong system. I have had very little problems with them. And don't even think about trying to take my Cinemmecannica Vic IVs away from me. I like 'em.
You can have the Vic 8s if you want.

Platters combined with a quality automations system (properly


installed) and well maintaned projectors make for a nearly trouble free booth.

Bernard, what a good photo! I felt right at home in that booth! Oddly enough the first cinema I worked in had the walls painted that exact shade. Those pics brought it all flooding back. My booth then was almost identical, swap the Westars for GK21's and there you have it.

Fully loaded, they probably were pretty damned heavy. Were the 48" reels the ones commonly used on the Eprad Wall-MUT? The reels I have always seen on those seemed pretty damn large.

Stephen,

Done it. The beauty of a platter is of course that you have a nice smooth, constant takeup tension, so I've never actually had a film break like that. I have however been in a theater where the leader to trailer splice was so poorly made that it caught in the failsafe and started dumping film onto the floor. I caught it during the second trailer (timer starts, 1 projectionist running two complexes) and was able to prop the failsafes up with a Q-tip while I got the film back onto the takeup platter without ever stopping the show. I fail to see your beneficial argument over towers vs. platters though. The takeup on a platter and tower is the same thing, just one is turned horizontally.

I’ve worked with both systems and most of the big issues have already been covered in this thread - but what are the differences in price? How much is a AW3 compared to a Westrex tower?

Also, with a 4 or 5 deck platter, you can have up to 4 separate programmes in one hall without having to lift a print. And each one up to 270 mins long, too!

We quite often have alternate programmes in our cinema (Film A at noon, Film B about 3pm, Film A again about 6pm and film B at 9pm). Which means, using platters, we can join both shows together, trailers and ads too, into one giant roll of film requiring only 2 lace-ups per day. Quite handy when it's down 2 flights of stairs, through a screen, down more stairs, through the foyer then up three flights of stairs!!!

Just out of interest, what's the longest running time you’ve dared to put on a platter OR tower?

By the way, Bernard, you said "These would not fit the Westrex Tower as I know it, although I suppose it might be possible to raise the pay-off & take-off assemblies higher in the frame. The spools shown in the page 1 pictures are 36” diameter."

I did see an abnormally large film being shown on a tower - it had been slightly raised off the floor and the take-up spindle had been extended or offset somehow so the reels wouldn't clash. They were using 12k spools but running far too much onto it (not recommended!!!)

>>what's the longest running time you’ve dared to put on a platter OR tower?<<

PLATTERS:
(Single Features)

Branaugh's 'Hamlet'(Estar) and 'Das Boot: The Director's Cut'(acetate) on a 48" CFS Super Platter took it to within 1/2" of the edge.

'Amistad' on a Christie MW3 Miniwind (42" discs) came to within 3/8" of the edge.

I have also placed double features on AW2, AW3 and Norelco platters that came pretty close to the edge as well.

TOWERS:

'Amadeus' overfilled the reel by about 4" on the Cinemeccanica DGB tower (and amazingly stayed put) Usually i would split looong films like that in half.
