Abstract: A rotating nozzle assembly for a die machine connectable to a dough extruder has a stationary sleeve with a first end having internal and external annular recesses and an annular stepped seating surface and a second end mountable in the die machine mounting plate. A nozzle has a first end rotatably disposed in the stationary-sleeve first-end internal annular recess, a second end and a radially outwardly-protruding annular ring between the first and second nozzle ends. A ring seal is disposed between the stationary-sleeve first-end annular stepped seating surface and the radially outwardly-protruding annular nozzle ring. A nozzle cap is fixedly attached to the stationary-sleeve first end. The nozzle is rotatably disposed in the nozzle cap. The nozzle second end extends beyond the nozzle cap. An annular stepped axial thrust bearing surface in the nozzle cap prevents relative axial movement of the nozzle while allowing rotation of the nozzle.

Abstract: A rotary drive nozzle die machine for an extruder includes a rotatable nozzle having first and second axial ends and at least one opening at the second end, a compression head for directing a food material to the nozzle, and a drive assembly including a tubular drive sleeve configured to rotate the nozzle and from which the nozzle is axially removable. A housing is provided in which the nozzle rotates. A wire ring coaxially surrounds at least a portion of the nozzle and provides a snap-fit connection with the housing such that relative axial movement of the nozzle and the housing is prevented while allowing rotary movement of the nozzle with respect to the housing. A rotary seal is between the nozzle and the housing and includes a first segment extending from the first axial end of the nozzle radially outwardly to and contiguous with an axially extending second segment.

A housing is provided in which the nozzle rotates, and includes an annular recess. A wire ring coaxially surrounds the nozzle and provides a snap-fit connection with the housing such that relative axial movement of the nozzle and housing is prevented while allowing rotary movement. A rotary seal is between the nozzle and housing, and includes one or more annular washers and an annular O-ring surrounding the rotatable nozzle and located radially between opposed facing annular surfaces of the recess and the nozzle. A first washer contacts an axially outwardly facing surface of the annular recess.
