Abstract: In the case of a two-apron drafting unit for spinning machines, it is provided for the parallel alignment of the top apron cradle and of the pressure roller twin guided by it with respect to the pertaining bottom cylinder that the pressure roller holder arranged in the load carrier only takes over the function of providing the load and the lateral guiding. The parallel alignment of the apron cradle is caused by a preferably L-shaped stop against which the apron cradle will be placed. The shaft of the pressure roller twin is unguided in the radial direction in the pressure roller holder.

Abstract: An apron drafting system for textile fibers includes a pair of front rolls, a pair of middle rolls, and a pair of back rolls defining front and back drafting zones therebetween. A cradle, including a pair of side plates, is mounted on both of said middle rolls and extends towards both said front rolls and said back rolls to support a pair of front apron pins adjacent the front rolls and a pair of back aprons pins adjacent the back rolls. Top and bottom aprons extend over the middle rolls and over the apron pins adjacent both the front and back rolls to make adjacent contact to guide the textile fibers from a point immediately adjacent the back rolls, through the nip between the middle rolls, to a point adjacent the front rolls.
