Device for producing strand shaped composite material from roving, has outlet channel with funnel inlet into which nozzle protrudes to form ring gap, where roving is saturated with homogeneous mixture of reaction components

摘要

The device has a mixing head (40) with a mixing chamber (430f), and a channel (418) for a roving (50) fed through an outlet of the mixing chamber over an injection nozzle (423c). One of another two channels (420d, 430d) for reaction components (60, 70) such as isocyanate and polyol, has outlets (420e, 430e), which are arranged such that the components are turbulently swirled in the chamber. An outlet channel (443b) has a funnel inlet (443a) into which the nozzle protrudes to form a ring gap (443c). The roving is saturated with a homogeneous mixture of the reaction components. An independent claim is also included for a method for operating a device for producing a strand shaped composite material from a roving.
