All LACO 52 coating units are built of corrosion-free anodised Aluminium parts with stainless steel rollers. Through the electro-mechanical connection to the Plus-Version drive of the Heidelberg printing press, an absolute synchronized production with the printing press is guaranteed. The roller coverings are resistant against UV-coatings, therefore a production with all suitable water based an UV-coatings is possible without modification of the coating unit. Through an additional rubber blanket cylinder (which is part of a LACO 52 coating unit system) according coatings get applied in the same sheet passage with the printing process inline. The coating application amounts are continuously adjustable from 1–10 g/m². Since more than 20 years of experience in coating unit manufacturing, our machines made in conventional 3-roller construction are proven in many countries worldwide. During a coating production, a LACO 52 coating unit will be driven through the numbering drive (Plus Version) of the Heidelberg 52 press. As soon as the press stops, a self-drive motor get automatically switched on to keep the rollers inside the coating unit in rotation, to prevent the drying of water based coatings on the rollers.
