TS Converting recently supplied a 1,600 mm wide slitter with an 800 mm rewind diameter to London based film converter PSG, for use in its cleanroom. It is the third TS machine for PSG, which carries a wide range of coated and plain films, specialising in rapid delivery.
“Our class 8 cleanroom has opened the doors to many food and medical packaging customers, as we are accredited to BRC B and ISO14644,” comments Lawrence Gardezi, managing director of PSG. “We are very happy with our existing Elite Cameron machines but the benefits of the short web run and quick change-over on the C800 are very significant. We can complete a full knife and reel set-up in less than five minutes with minimal wastage.”
The new machine has the latest dual direction, pneumatic differential shafts for both 76 and 152 mm cores.
“These shafts work extremely well at low tensions,” claims Tim Self, director of TS. “We have successfully run very narrow slit sizes, as low as 20 mm, which would not be possible on conventional centre winders”
The machine is equipped with razor and shear slitting, auto edge guide, laser core and knife positioning, automatic tension control, lay-on rolls and the latest SSD digital AC drives. The male and female knife shaft bearing supports are removed, leaving the shafts cantilevered for knife replacement.
The very short web path from the slitting section to the rewind is said to reduce any potential for web movement dramatically. The slit strips are also secured in position during finished reel removal using a web clamp to maintain registration through the machine for the next set of cores.
