Method and apparatus for producing spiral pet treat

Abstract

A method and apparatus for the automated mass production of spiral body pet treats, particularly chewable, spiraling rawhide-type pet treats, employs an extruder for extruding at least one rope in the form of a spiraling cross-sectional body having a plurality of radially spaced layers and an outer terminal end portion which is radially in-turned and conjoined with an adjacent one of the plurality of radially spaced layers. The rope is cut by a cutting assembly at longitudinally spaced locations in creating spiral shaped intermediate products which are then dried to form the spiral body pet treats. The spiral body pet treats are hard when dried but, with the radially in-turned outer terminal end portion being joined to a radially inward spiral layer, no terminal edge with potentially sharp contact points is exposed.
