Hello all,
I have taken delivery of a new Summa S160 T series . I am cutting heat transfer vinyl (PU) to press on cotton materials.

No problems for the first day but then I think I might have touched something and now the vinyl bows and creates a wave in the forward feed. I am trying to get around the problem by panelling every 30 cms. I have slowed the cutting speed down to half of its capacity. The vinyl still creates a wave and this results in cutting errors - wasted vinyl

The machine was supplied with 4 pinch rollers. I can take the pressure off the center two rollers if required and just run on the outer rollers.

Does anyone have any advice for me?

Thanking all for their input
