Patent number: 7313908Abstract: 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).

Patent number: 6978594Abstract: A sawtooth wire to be laid in a groove of a shredding-element-carrier of a disintegrating roll of an open-end spinning apparatus is brought into a shape, which essentially represents that shape, which the sawtooth wire is to assume on the shredding-element carrier. The sawtooth wire is preshaped on a dummy body, the circumference of which predominately conforms to that of the shredding-element carrier, or the sawtooth wire is directly preshaped on the shredding-element carrier of the disintegrating roll. The preshaped sawtooth wire is subsequently hardened, preferably inductively with the aid of a high frequency alternating current with a frequency of more than 1000 kHz. In this manner, a disintegrating roll is made, the abrasion resistant shredding element of which, after the preshaping, i.e., after is securement on the shredding-element carrier, is a hardened shredding element.Type: GrantFiled: February 7, 2002Date of Patent: December 27, 2005Assignee: Rieter IngolstadtInventors: Edmund Schuller, Klaus Schoberth, Josef Schermer, Heinrich Mayer, Herbert Kreis

Publication number: 20050029387Abstract: In order to drive a spool on a textile machine, a friction roll is provided, having a rotating body, carrying at least one friction ring. This friction ring is designed in the manner of a belt with two, open ends that are clasped together by two connectors. The two connectors, when linked together, form a releasable end fastening apparatus. The two connectors exhibit in this linkage, interlinking hooks. The fastening apparatus for the friction ring ends can serve simultaneously as a ring fastener to the friction roll. Further, the friction ring can be affixed, at a distance away from the two open ends, onto the friction roll with additional fasteners, which are uniformly distributed around the circumference of the friction roll. The two connectors and/or the friction ring exhibit a preselected radius of curvature which adapts to the radius of curvature of the outer circumference of the friction roll.Type: ApplicationFiled: December 2, 2003Publication date: February 10, 2005Inventors: Edmund Schuller, Dietmar Greis, Manfred Knabel
