A machine for machining sheets comprises an arrangement for compressing the sheets to be machined. The arrangement is rotatable about a longitudinal axis comprises at least two rollers for bearing resiliently against the sheets during machining, each of which rollers are rotatable about a transverse axis perpendicular to said longitudinal axis. The arrangement is driven by a motor via a pinion, which motor also drives reduction gearing connected to an angular control means whereby it is possible to control the angular position of the arrangement so that the axis of rotation of the rollers can be orientated in relation to the direction of machining. The control means are themselves controlled by programmable electronic means which operate with reference to the angular position of the machining head of the machine. |
