Rotary buffer squeegee units are commonly used to remove surface water before film drying and before sound track application. The number of units necessary depends upon the speed at which the film or machine is running and upon the amount of squeegeeing needed. Complete removal of the liquid on the film surface usually requires more than one squeegee unit. The fibers on the roller surface are dry and clean when they touch the film on the next revolution.A rotary buffer squeegee unit consists of a pair of driven rollers. The liquid whisked from the film by the fast-moving plush is immediately thrown away from the rollers by centrifugal force. ![]() They rotate at high speed, opposite to the direction (counter rotation) of the film motion, lightly contacting and wiping both surfaces of the film. The rotary buffer squeegee consists of two or more pairs of plush-covered rollers, one roller on each side of the film. Maintenance is simply cleaning, replacing worn blades, and adjusting mounting brackets.Ģ. It is inexpensive, quiet, requires no air or electrical connections, has no critical tolerances to set and maintain, and no bearings to corrode or stick. The correct pressure of the wipers against the film will remove all visible solution, but will not damage either the emulsion or the support.The wiper-blade squeegee has several advantages over other types of squeegees. Wiper blade squeegees* consist of two blades, one touching the emulsion side and one touching the support side of the film, which by means of slight pressure, remove adhering solution from the film and direct the solution back into the tank. Common squeegees include: wiper blade, rotary buffer, air stream, venturi air stream, vacuum, and wringer sling.ġ. The normal position for a squeegee is just above the machine tank so that the solution removed from the film returns to the tank. They remove solution from both sides of the film strand. Track Developer Applicator for Color Films, Journal of the SMPTE,63:191-194, November, 1954.Crossover SqueegeesCrossover squeegees minimize the loss and dilution of processing solutions resulting from the carry over of solution or wash water by the film from the preceding tank.
