DEFINITION

Classification: 28/252

(under subclass 247) Method or apparatus wherein the thread is textured in a predetermined intermittent or nonuniform manner such that the production of coils, crimps, crinkles or like distentions is varied along the length of the thread.

(1) Note. This subclass usually contains those devices modified to produce a pattern or program controlled discontinuous or irregular texture in thread. The production of a discontinuous or irregular textured thread without design, as by those devices which by their very nature produce such effect in a random manner, e.g., fluid jet texturizers utilized to interlace thread as a twist substitute, will be found elsewhere.

SEE OR SEARCH THIS CLASS, SUBCLASS:

243, for producing irregular or variable denier in thread during a stretching operation.

271+, and particularly 275, for producing discontinuous or irregular entangling or interlacing of thread due to resonance in fluid jet texturing.
