Improvements relating to the manufacture of polyurethane coated materials by the transfer coating particularly imitation leather materials

摘要

Apparatus for the manufacture of polyurethane coated materials by transfer coating, includes means 11, 13, 15 for successively applying layers of polyurethane material 101, 102, 103 to a laminar support material, 100, eg release paper, means 18 for calendering the coated support material 100 with a second material 200, eg fabric, means for subsequently separating the support material 100 from the calendered second material 200 and polyurethane layers 101, 102, 103 and a plurality of drying furnaces 12', 14', 16', 19' for at least partially drying the material after each process stage. At least one of the furnaces (preferably the furnaces 16' and 19') include short-wave infra-red heating means.
