A drawing frame comprising, starting from a main frame (1), a sliding frame consisting of several actuators (20, 22, 23) arranged in a straight position on the elements drawing the sheath (5). The various actuators (20, 22, 23) are guided by slide rails (13, 14) and in particular by a pair of dihedral structures (7) for example, comprising beams (10, 12) and slides mobile by the effect of the various actuators. The drawing frame can advantageously be installed on a machine used for making silos, for sheathing fodder bales for example.
