During lamination one side of the raw material is applied with a thin uniform layer of adhesive, then the other material is pressed against it by assuring no air is left between the two, thereby producing a duplex raw material. By repeating the same step, we can produce a triplex material structure. Our winding laminating machines operate with solvent free lukewarm adhesives enabling efficient and high quality production of even small quantities and replace the previously used solvent technology harmful for the environment.
The removable side-shift sleeve laminator consists of 5 cylinders out of which two are tempered in order to control the temperature of the adhesive. The laminating cylinder is a built-in air-cylinder onto which rubber sleeves can be pulled from the side of the machine with the help of special valves. A rubber laminator sleeve is pulled over to the center of the air-cylinder, shorter than air-cylinder’s mantle (cut to the exact length of the laminating width).
The speed of the laminating cylinder is controlled, raised and actuated by separate servo-motors. The pressure roller is actuated by pneumatics with central compressive force control. The thickness of the adhesive is controlled by a continuously variable transmission, enabling the application of 1 g/m2 adhesive thickness, though the optimal thickness is 1,8-2 g/m2. This setting can be changed even during production. The temperature of the metal pressure roller and the heated rollers of the laminator unit is provided by a temperature control device, preventing overheating. A color touch-screen terminal is used to control adhesive thickness, programming of the meter counter, saving parameter settings and other functions. Corona surface treater, antistatic equipment and adhesive vapor exhaust unit are optional.
