Abstract
Method for strip-coating a metallic strip-shaped substrate (1) with a band (3) of plastic comprising the stages: (i) in-situ casting of a plastic band; (ii) leading the plastic band around a cooling roll (5, 5a); (iii) leading away the plastic band until the plastic band production is underway and stabilized; (iv) bringing the plastic band up to speed and heating the substrate to a temperature of the substrate close to the softening temperature of the part of the plastic band facing the substrate; (v) pressing the plastic band onto the substrate and where applicable breaking off the plastic band and stopping it being led away; (vi) coating the substrate (1) with the plastic band (3) at high speed.
