Abstract
A method for producing coated strip by continuously applying a film of the coating to the moving strip comprises trimming at least one edge of the film before it makes contact with the strip by a stationary or moving cutter which is responsive to the position of the adjacent strip edge. Both edges of the strip may be trimmed by separate cutters which can be coupled so as to be simultaneously responsive to the position of one edge of the strip only. Alternatively the cutters may operate independently on both edges of the film, with each cutter being responsive to the respective strip edge. The cutter or cutters may be secured to a pivoted arm which carries a shoe arranged to engage the corresponding strip edge so that the cutter moves in unison with this edge.
