The pillow belt consists of:
- A support belt (a 2 or 3 ply belt either in TPU or PVC)
- A series of welded pillows by High Frequency machine (HF)
The pillows are fabricated from either a 1 or 2 ply belt, of the same material of the support belt. The number of pillows, their height and length are the main characteristics that are needed for the fabrication. They can be welded in a continuous manner or spaced.
