Hello,

Here is a professional Film Splicer for Polyester films :

No glue or thinner necessary as this is a welding machine ( Ultra Sonic Welding Method).

Unfortunately...........Very Expensive!!! (Around 2000Euros).

But at this time , this is the best method (Welding : the strenghness is identical to polyester base).

From what I remember, Derann was using an equivalent machine, just to be confirm...

is this the machine that make small squiggles in the film to mend them together?
Tape is much cheaper thanks. [Eek!]

2000 euros? [Eek!]

really?

ive used tape for 35 years, cut in half to cover only two frames and its worked perfectly. 2000 euros????
one could buy a new projector and many films for that, very nice but i to will stick to tape. Decent tape splices are equally as good.

2000 Euros = $2263 = £1566 approx.

Sounds great, no hinging effect at the joint, but at what price. As tom says tape has been used for such a long time we have put up with our own inability to make an excellent tape joint, over time you will get proficient at this, and not at the huge cost. I would love to see how it does this so much better, an interesting science, just a pity its so much money.

Hello,

Of course 2000 Euros is expensive for common users only, but this device is a professional machine, means, is supposed to make hundred and hundred splicing for a year offering always the best result.
In that case , there is a kind of pay back at the end.....

Also, I understood this device is very usefull for Labs when splicing Negatives in a dark Room as Laboratories need a perfect result.

Paul, yes, as I wrote before, in case "Super 8 market" is back to health, the splicer could be much less expensive .

Sounds like the sort of think Kodak might have for splicing the new Super 8 films for processing if they make them on Polyester.

Mind you I did once hear that Superglue was developed by Kodak to join Polyester film, I'm not sure that it is true.

2k euros or not, you are still forced to lose a couple of frames when any bonding or welding method is deployed!

Useless for the pulse sync fanatics. [Confused]

I will be sticking with Jackro tape/ Metal bodied C.I.R. combo myself. [Wink]

I have a Derann print that I'm pretty sure has a lab splice in it.

-now I have to check it out!

Then again If these splices are that good, how did I notice it?

I think all lab splices were done that way. They certaintly never used tape. Not a bad idea myself, but would never pay 2000 for it.

For lab splices, it works, no missing frames.

For post production home use, if you wish to keep the accuracy of matching the original negative frame to frame as well as the original soundtrack, it's useless as said.
