<p>A movably mounted and adjustably positionable feed-roll head for a food extruder of the like (110, 210) having a unitized head assembly which includes at least one feed-roll (114, 116, 214, 216) and its related operational structure and rigid but movably mounted supports (124, 224, 225) for each end of the feed-rolls and related structure, whereby the entire unitized assembly may be moved relative to the remainder of the extruder for cleaning, die change, etc., without disassembly or removal of the feed-rolls, etc. The preferred mounting for the unitized structure is a pivot mechanism (126, 226, 227) for each of the feed-roll supports, and a readily adjustable repositioning mechanism (128, 228) such as a screw jack assembly (232) is coupled to the other side of the feed-roll supports, whereby gradual and progressive position changes of the unitized feed-roll assembly are made possible. The unitized feed-roll assemblies may include a pair of cooperatively mounted feed-rolls (114, 116), and two or more such unitized assemblies (224, 225) may be used together in a single extruder, with each such assembly being adjustably repositionable, either separately or cooperatively.</p> |
