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. The cradle also includes a pair of platform members, one in the front drafting zone and another in the back drafting zone, which serve to deflect the top and bottom aprons where they are in abutting contact out of the normal path between the rolls to provide improved control over the textile fibers while in the drafting zones.
