In the duplication process, the adhesive coating is transferred from the transfer to the substrate. Siliconized paper is used as a transfer, and the backing can be film, fabric or nonwoven material. The roll of transfer paper is put on the roll, which is placed with the help of a hoist (suspended lifting device) in two safe chucks of unwinding unit No. 1. The roll is fixed, after which the transfer paper is pulled through a four-zone convector-type drying chamber. When leaving the drying chamber, the end of the transfer paper is tucked through the cooling and lamination unit and fixed on the roll of the winding unit. A roll with backing material is installed in unwinding unit No. 2. The end of the backing material is pulled through the frame of the winding unit and the guide frame. At the same time, the material is placed in such a way that at the entrance to the cooling and lamination unit it is facing the adhesive coating. After all these preparatory measures in the coating unit, the knife is put into working position. The line is set in motion by pressing the “Start” button on the main control panel.

A barrel with acrylate adhesive is installed in the coating unit. Using a pump, the adhesive from the drum is fed from the drum through a silicone hose to the siliconized paper moving under the knife. As the paper belt moves through the gap between the drum and the knife, the acrylate adhesive is entrained by the moving belt. At the same time, excess adhesive is removed by the knife, resulting in an even layer of acrylate adhesive coating the paper. The adhesive-coated paper strip passes through the drying chamber as the conveyor belt moves. In each of the four drying zones, hot air heated to a predetermined temperature is directed onto the surface of the adhesive-coated paper. The exhaust air is discharged from the drying chamber by means of an exhaust fan. The paper, while moving from the unwinding unit No. 1 to the coating unit, passes through a control system where its thickness is measured. The second device of the thickness control system is installed at the outlet of the drying chamber, where the thickness of the paper with the applied adhesive coating is measured. The comparison of the two measurements gives the thickness of the adhesive coating, which the operator can adjust by increasing or decreasing the gap between the knife and the drum.
