A two-bar linkage, consisting of links 4 and 5, is connected by turning pairs E and H to four-bar linkage ABCD. Grip 7 is rigidly secured to link 4 by means of which it folds the cloth on segment 6. The cloth is held on the segment by means of lever 8 having weight G at one end and fork a at the other. Fork a engages pin b of link 5. The cloth is fed to the segment by a special mechanism which is not shown.
