DEFINITION

Classification: 28/107

(under subclass 103) Method or apparatus wherein the rearrangement of the component members of the nonwoven textile article or structure is effected by surface penetration thereof by thin, usually barbed, rods, bars or the like.

(1) Note. The needling operation is usually performed by banks of reciprocating needles with the feed of the starting material being stepwise between successive needle penetrations to bind together adjacently disposed fibers with respect to themselves and/or to a substrate in the formation of a unitary, coherent article or structure.

(2) Note. The effects of the needling operation may be varied, including the uniting of discrete articles or structures to each other, the creation of an upstanding pile on a substrate, drawing or stretching of the component members of the article or structure in addition to the reorientation or rearrangement thereof, innumerable aesthetic applications in addition to conventional usage.

(3) Note. The needling of a thread interlaced article or fabric, per se, is not proper for this subclass.
