SQUEEGEES DESIGNS

---

Squeegee

Squeegee lips or wipers wipe the solution from the film; they are made from rubber or plastic often with metal or other types of inserts to influence the rigidity of the wiper.

Some modern designs use specialised plastics and are extraordinarily resistant to damage.

Vacuum squeegees

A small vacuum pressure applied between two sets of wipers removes the solution and lets it run to waste.

Air knives

Air knives, is air pressure used to blow solution from the film.

They have the disadvantage that they are often noisy.

Those using the "Venturi" principle are the most efficient.

Buffers

Contra-rotating mechanically driven buffer rollers of felt, sponge or velvet are used in some processes as squeegees or as "wringer-slingers" to remove backing or water.
