DEFINITION

Classification: 112/80.54

Variable height loops:

(under subclass 80.5) Device wherein the strand loop engaging, holding, or guiding means engages, holds, or guides strand loops of differing lengths which have been formed on the base material.

SEE OR SEARCH THIS CLASS, SUBCLASS:

80.52+, for plural loop catchers having different shapes or orientations which may engage, hold, or guide strand loops of differing lengths which have been formed on the base material.

80.55+, for tufting devices including loop catcher structure with loop cutting means which cuts a strand loop thereby forming two strands of unequal length.

80.70+, for tufting devices including yard manipulating means for producing variable height strands or strand loops on the base material by varying the rate of feed of the strands to the strand inserting means (e.g., backdrawing).
