Abstract

A process for forming extruded multi-strand products. The process providing a braiding extruder which includes a first rotatable member, a second rotatable member, a rotatable member driving system, and an orifice blocking arrangement. The rotatable members each include a pair of orifices for extruding a strands of extrusible material therethrough. The orifices are fluidly coupled to a source of pressurized extrusible material. The process includes (i) blocking unblocked orifices, (ii) preventing the extrusion of extrusible material from each blocked orifice, (iii) unblocking blocked orifices, (iv) extruding a strand of extrusible material from each unblocked orifice, and (v) alternately rotating the adjacent rotatable members in opposite directions. The process automatically forms a visually attractive product which reaps the benefits of the 'hand made' appeal normally associated with braiding.
