Abstract
A mechanism (10) includes a slide plate (32) having die openings (38) adapted to hold dies (42a, 42b) and slideable relative to a cooker/extruder (12). Rotary cutters (74, 174) are rotatably mounted relative to and moveable with the dies (42a, 42b). In one preferred form, a motor (76) can be connected and disconnected to the rotary cutter (74) aligned with the cooker/extruder (12) by moving a male coupling (96) within or out of a female coupling (108). In another preferred form, the rotary cutter (174) is mounted to and carried exclusively by a center shaft (180) fixed to the die (42a, 42b) and includes provisions (187, 191) located within a housing (183) for rotating the housing (183) on the center shaft (180). Thus, it is not necessary to shut down the cooker/extruder (12) to service or change the dies (42a, 42b) and/or the rotary cutters (74, 174). An annular wear plate (134) is sandwiched between the slide plate (32) and a frame element (18) having a central aperture (126) into which the barrel (14) of the cooker/extruder (12) is slideably received. A center plate (130) extends through the wear plate (134) and is received within the central aperture (126) and is fastened to the…
