#CMT# #/CMT# The frame (1) has an apron pair (3) including an upper apron (31) guided above a press cylinder and a deflecting part (5) and a lower apron (32) guided above a lower cylinder and a fixed guiding table (4). An outlet roller pair (2) is attached to the pair with respect to a transport direction of a roving and formed by an outlet press roller (21) and an outlet lower cylinder (22). The distance of the table from an outlet clamping line (A) is larger than that of the part. The distance of a passage line (S) to a surface of the outlet lower cylinder is smaller than that to a surface of the roller. #CMT#USE : #/CMT# Drawing frame i.e. three cylinder-drawing frame, for warping a roving in a ring spinning machine i.e. staple fiber-spinning machine, which is utilized for producing yarns (all claimed). #CMT#ADVANTAGE : #/CMT# The distance of the passage line to the surface of the outlet lower cylinder is smaller than that to the surface of the outlet press roller, thus reducing the hairiness of the yarn. The firmness and uniformity of the yarn are hence improved, so that the quality of the produced yarns is improved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of a drawing frame.
