ABSTRACT:
A texturizing apparatus comprising a drive housing having a false twist inlet to allow a plurality of yarns to enter the drive housing, a pair of opposing counter-rotating nip rollers positioned downstream of the false twist inlet, each nip roller having a circumferential drive surface adapted to engage the plurality of yarns and at least one circumferential spacer surface, and means for applying compression to one of the nip rollers to force the at least one circumferential spacer surfaces of the pair of nip rollers toward each other. The drive housing further having a drive outlet positioned downstream of the pair of counter-rotating nip rollers through which the plurality of yarns may exit the drive housing. The texturizing apparatus can also include a stuffer box having at least one movable flapper door and a box inlet positioned proximate the box inlet and of a size to allow the plurality of yarns to enter the interior of the suffer box. The stuffer box has a box outlet through which the yarns may exit the interior of the suffer box, which has an opening size partially defined by the at least one movable flapper door.
