Special surface grooving is widely used in various fields. The main purpose of the grooving are:
- To increase the amount of coating
- To smooth out wrinkles in plastics flim and papers
- To prevent belt slipping and meandering
- To emboss on plastics
- To assist the heat release from rubber rollers
- To apply softness of rubber rollers
- To raise the coefficient of friction
- To improve contact stability with papers or plastic films
