The laminating technology means simply covering the surface of one of the materials with adhesives and pressing the other material onto it ensuring that there is no air left, producing a duplex material. Repeating the same activities we can produce a triplex material structure. Our solvent free, winding laminating machines are operating with lukewarm glues enabling the efficient and high quality production of even small quantities and the previously used environment harming solvent-using technology can be replaced.
The side-change sleeve system based on laminating work consists of 5 cylinders out of which two are heated in order to control the temperature of the adhesive. The laminating cylinder is an in-built air-cylinder onto which rubber sleeves can be pulled on from the side of the machine with the help of special valves. The rubber sleeve's width is less than the air-cylinder's width and equal to the laminating width. The speed of the laminating cylinder is controlled, raised and moved by detached sevo-motors. The pressing cylinder is moved by pneumatics with central pressure control.
The thickness of the adhesive is controlled by a stageless gear, enabling the application of an adhesive thickness as less as 1 g/m2, though the optimal thickness is around 1.8-2 g/m2. This setting can be changed even during production. A coloured screen terminal is used to control the adhesive thickness, the programming of the meter counter, the cylinder heating, the saving of parameter settings and other functions. Corona treatment unit and adhesive vapour exhaust unit are optional.
