  • Patent number: 3994658
    Abstract: An extruder for simultaneously forming a plurality of clam strip shapes from a single source of extrudable material including particles of clams therein. The extruder includes a nozzle body which terminates in a nozzle opening and a forming member in operative relation thereto for use in forming the extruder product. A divider member within the nozzle body divides the nozzle opening into a plurality of nozzle openings and also divides the forming member into a plurality of forming members.The divider member extends upstream within the nozzle body to an upstream end which is maintained free of clam particles by virtue of a deflecting member which is mounted on the upstream end thereof. The upstream end of the deflecting member presents a downstream convex surface to the extrudable material and thereby prevents accumulation of the clam particles on the upstream end of the divider.
