摘要：
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.
