Abstract

913,685. Coating surfaces. SUNDES FABRIKKER A. S. Feb. 6, 1959, No. 4269/59. Class 95 [Also in Groups VIII and XXVIII] Rods and tubes are made by forcing a foamforming polyurethane mixture from a head or nozzle A on to a former B which is moved in relation to the head or nozzle, so as to form an even deposit thereon, the mixture after being deposited attaining a foamed structure with a smooth and compact surface layer. The former may be a rod, which may be rotated and moved longitudinally, or a strip of material, e.g. textile fabric.
