CROWN MACHINERY R-LTDA adhesive coating line

CROWN MACHINERY R-LTDA adhesive coating line was built in 2012 in Taiwan by Crown Machinery Co., Ltd. (Crowntex). The machine, designed to coat different types of surfaces with adhesive, is an excellent choice for the serial production of, among others, adhesive tapes, labels and patches. This is because it supports a wide range of water-based as well as solvent-based adhesives with varying degrees of viscosity. Acrylic, synthetic rubber or natural rubber can also be used for the adhesive layer. Thanks to its high flexibility, the CROWN MACHINERY adhesive coating machine can also be used in research for the development of new types of coatings.

Media such as paper, films (PP and PE) or textiles are coated by means of state-of-the-art work heads. The material is fed on 530 mm wide rollers, which allow the operating speed and tensile force to be precisely adjusted to suit the individual properties of the material. A specially designed oven with four heating zones, in turn, ensures even drying of the media while saving energy at the same time. A data acquisition and analysis system (SCADA) collects all key process information, enabling full control of the production flow and seamless integration with the other machines in the line. The R-LTDA coating machine weighs 22 tonnes.
