Avantra 44 Buckle film inside drum when loading
Avantra 44 Buckle film inside drum when loading
Hi Guys,
I have a random problem, the film is loaded till the end and just in the last second the machine is like jumping the supply roller and the take up roller to the inside direction the drum like tensioning back the film over the drum to seat but too much producing the film bucke inside the drum, its a small pulse.
I used the same Cassette and new Roll of films and in both A and B supply postions and it happens more often only in Cassette B.
I couldnt find the problem, the A is not doing that.
The B sometimes like 8 from 10.
I checked the tension in the supply cassttes, the film, the presion in both A - B supply rollers and modified it in different condition with more and less pressure on B also the checked the feed motor, exchanged the SDM, reloaded all the DEC - DSP and OCP software.
And still the same.
There is any specifica parameter to adjust the tensioning procedure t oseat the film on B and A separatelly ?
If nota Why on B is more often ? I got it only once in A from 100 times. (probaly miss handling in that case) so I assume A is perfect.
I checked take'up rollers and aslo loaded film with and without Bridge OLP option ( Online and with Take'up cassette)
Any help _ suggestion will be highly appreciated.
Thanks
Adrian
