ABSTRACT:
A disintegrator apparatus for textile machines is provided that includes a plurality of teeth at a tooth spacing (LZ) of no greater than about 20 mm and preferably less than about 12 mm. The teeth generally include two sections. A first section is located at a tooth apex and exhibits a positive or at least a vertical forward rake (WB). A second section is at an incline, falling in the direction of movement of the operative equipment. The separation distance between the apex of the tooth and a tangential joining point of the vertical tangent creates a transition zone between the first and second sections and forms a technologically effective tooth height (Ht). The ratio of the technologically effective tooth height to the spacing between teeth no greater than about 1.
