DEFINITION

Classification: 28/170

(under subclass 165) Method or apparatus wherein the treatment involves (a) dividing a textile structure, or (b) opening such a structure when in tubular form either by penetrating the structure with a severing device or severing force or by withdrawing a strand which is used to temporarily secure one segment or portion of a textile structure to another.

(1) Note. "Detacking" i.e., the opening of a thread interlaced textile structure from tubular to planar form by removal of a draw or temporary retaining thread is included herein as is the removal of a draw or temporary retaining thread to separate a thread interlaced textile structure into discrete articles or items.
