The invention concerns a disintegrator apparatus for textile machines, especially for spinning machines, i.e., openend spinning machines, with a disintegrator, on the outer circumference of said disintegrator a plurality of teeth (2) are placed. The invented disintegrator apparatus characterizes itself thereby, in that the teeth (2) are placed at a tooth spacing (LZ) of, at the greatest, 20 mm, preferably less than 12 mm and said teeth at least consist of two sections, whereby a first section located at a tooth apex (5) exhibits a positive or at least a vertical forward rake (WB) and a second section is an incline, falling in the direction of movement (3) of the operative equipment, and that the separation distance between the apex of the tooth (5) and a tangential joining point of the vertical tangent (10) creates a transition zone between the said first and the second sections and forms a technologically effective tooth height (Ht), whereby the ratio of the said technologically effective tooth height to the spacing between teeth is at the most, unity, i.e., 1.
A disintegration apparatus for textile machines, especially for spinning machines, namely spinning machines of the open end type, having a disintegration apparatus, on the outer circumference of which a multiplicity of teeth (2) is placed, therein characterized
A disintegration apparatus in accord with the foregoing claim, therein characterized, in that between the vertical tangent (10) and the second section, an angle lies, measuring 3° to 60°, preferably 30°-50°.
A disintegration apparatus in accord with one of the foregoing claims, therein characterized, in that the teeth (2) are found on a carrier wire, which is subsequently fastened onto a disintegrator roll body.
A disintegration apparatus in accord with one of the foregoing claims, therein characterized, in that the dimension of a tooth base (HF) of the toothed wire is less than 2.5 mm.
A disintegration apparatus in accord with one of the foregoing claims, therein characterized, in that the ratio of technologically effective tooth height (Ht) to the tooth base (HF) is between 0.2 and 1.5, preferably between 0.7 and 1.
A disintegration apparatus in accord with one of the foregoing claims, therein characterized, in that the forward rake (WB) lies in a range of 0°-10°.
A disintegrator roll for textile machines, especially for spinning machines having a toothed wire or a toothed ring, therein characterized, in that the therewith accompanying tooth contour is constructed in accord with one of the foregoing claims.
A toothed wire, or a toothed ring for textile machines, especially for spinning machines, therein characterized in that the therewith accompanying tooth contour is in accord with one of the foregoing claims.
