ABSTRACT:
A method wherein a thin card web which contains meltable synthetic fibers as well as natural fibers is processed into a thicker web of fleece. The synthetic fibers are initially melted to prestrengthen the web. Then the web is saturated with the appropriate fluid finishing agent for making the web flame-resistant and the like and this web can then be readily dried on a screen drum dryer. It is at this point that the web layers are accumulated into a proper fleece in a cross layer unit which transfer the end product to a heat treatment assembly for heating to effect vulcanization, curing or setting of the synthetic fibers.
