Abstract
Abstract The present programmer operates to produce variations in the bulkiness along the length of air jet textured yarns by producing an irregular pattern of impulses which does not repeat for a long length of time. The programmer includes a rotatable pattern wheel having depressions in the form of substantially radially extending grooves of irregular width and configuration on one face thereof. An air nozzle sensor is supported for movement in a generally radial direction of the pattern wheel to ''''read'''' the grooves as the pattern wheel rotates and to thereby produce periods of reduced air pressure in the system. An air pressure switch is operated by these reductions in the air pressure to cause the air jet texturing unit to form irregularly spaced slubs along the length of the yarn.
