Abstract

A drafting device for textile fibre rovings uses false twist and functions continuously in conjunction with 'mule' or 'ring' type spinning machines. The device comprises two rotary elements with annular shoulders surrounded by circular rims perpendicular to the axis of rotation. The frontal surfaces of the rims are partly opposed, and the shoulders co-operate tangentially to draft the roving. One of the rotary elements is mounted projecting outwards towards the other, so that the material to be drafted can be introduced easily from the side, between the two facing elements.
