  • Method of coating fiber strands with a plastic coating composition from individual coating constituents
    Patent number: 6838123
    Abstract: The invention relates to a method for coating fibers shaped as fiber strands (roving and mats) using a fluidized bed technique, wherein (i) the desired composition of the individual coating constituents is directly applied from the fluidized bed without previous compounding and (ii) the individual coating constituents contained in the fluidized bed are additionally mixed in the mass so that dissociation of individual constituents is substantially avoided. The invention also relates to a device for implementing the method.
