Abstract

Solid and/or liquid components, e.g. of a polyurethane foam mixt., are fed through a tubular mixer, and the band is e.g. introduced tangentially to the top of a mould. Consecutive band elements, rotated inside tubular mixer, are twisted pref. through 180 degrees, alternately in opposite senses; and overlapping flat end sections are pref. disposed at right angles. The overlap produces a flow constriction; thus inducing pulsing, which may be enhanced by a ring inside tube wall in this region. Rapid complete blending is achieved, even with widely diverse component flow rates and densities; and in situ or dismantled, cleaning is easy.
