Smoothing Press, Model SP, is a rotary lamination press used to squeeze and adhesive coated sheet or roll to a substrate. Commonly referred to as a set of nip rollers, this smoothing press can be used to combine sheets or rolls that are coated with a wet adhesive, or for the lamination of sheets using contact cements or film adhesives. The smoothing press is available in 18", 24", 32", 45", 50v and 60".
This laminating smoothing press has a fixed lower roller and a floating upper roller. The upper roller is designed to provide enough pressure to eliminate blisters, wrinkles and bubbles that may be trapped between the substrates, giving a high quality lamination. The pressure is sufficient enough to squeeze out the bubbles on the laminated material, but does not exert excessive pressure that would crush the flutes on corrugated or collapse foam core board.
The floating upper roll can follow variations in substrate thickness while maintaining consistent nip pressure. Both rolls are powered to provide positive pulling force and eliminate any slippage between the layers of the lamination. The nip rollers are covered with a urethane rubber for positive grip and to conform to surface imperfections in the lamination substrate. Rolls can be separated for cleaning or shutdown periods. The smoothing press is powered by a D.C. variable speed drive. Top speed is approximately 60 feet per minute but it can also be operated at lower speeds to match the output of the adjoining machinery. Several optional versions of the smoothing press are available. For situations where higher pressure is needed between the nip rolls the machine can be built with weight added to the upper roll frame, or it can be fitted with air cylinders to squeeze the rolls together. Another version is available with an adjustable opening of up to 6" between nip rolls; this is ideal for foam fabrication work.
