DEFINITION

Classification: 156/435

(under subclass 433) Apparatus uniquely adapted to the manufacture of a textile material having short filaments extending generally perpendicular to the plane of the material.

(1) Note. In these devices the filaments must be united or bonded while still of running or indefinite length. They may then be sheared to produce the pile fabric. The typical method involves steps of continuously looping parallel strands, bonding the loops to a backing and then shearing the loop tops to form the pile.
