The working principle of high speed tape coating machine

High speed tape coating machines using a dedicated high speed coating head, can effectively reduce the formation of air bubbles, the rolls are equipped with full automatic coating machine film, closed loop tension control, compared with ordinary glue coating machine has its unique advantages.

In the process of reverse roll coating, if the roll gap is relatively small, capillary number low enough viscosity or where speed is a small case, in a relatively wide range of speed ratio of flow is stable, can get the better of the coating surface quality.

High speed tape coating machine if the gap is large, in coating at high speed, is likely to air entrainment, coating many tiny air bubbles on the surface.
