         7 . The aligning assembly according to  claim 5 , wherein the aligning assembly further comprises two distinct centres of rotation, one for each curvilinear path. 
     
     
         8 . The aligning assembly according to  claim 1 , wherein the belt is an aspirated belt. 
     
     
         9 . The aligning assembly according  claim 1 , wherein the aligning assembly further comprises a feedback system connected to the at least one actuator and comprising devices for detecting a position of the continuous strip of corrugated cardboard, wherein the feedback system is configured to detect a deviation of the direction of advancement of the continuous strip of corrugated cardboard with respect to the median axis of the dragging device, and to selectively activate the actuator and change the orientation of the dragging device. 
     
     
         10 . An aligning group configured to align a strip of cardboard, comprising:
 a dragging device that is elongated along a median axis and configured to drag a strip of cardboard having a predetermined direction of advancement, wherein the dragging device comprises
 a frame that is elongated along the median axis from a first end to a second end, 
 a pair of rollers, wherein each of the rollers is engaged to the frame at a respective end, and 
 a belt mounted on the pair of rollers, 
 wherein one of the pair of rollers is a motorized roller configured to move the belt and drag the strip of cardboard along the median axis of the dragging device; and 
   an actuator connected to the frame of the dragging device and configured to change the orientation of the median axis of the frame so as to change the orientation of the direction of advancement of the strip of cardboard.   
     
     
         11 . The aligning group according to  claim 10 , wherein the aligning group further comprises a pair of guides extending along a path incident to the median axis of the dragging device, and wherein the dragging device is configured to be movingly disposed on the guides. 
     
     
         12 . The aligning group according to  claim 11 , wherein the dragging device comprises a plurality of wheels engaged at the first and second ends of the frame, arranged on the guides, and configured to slide the first and second ends of the frame along the guides. 
     
     
         13 . The aligning group according to  claim 12 , further comprising a support, separate and disengaged from the dragging device, wherein the guides are mounted on the support. 
     
     
         14 . The aligning group according to  claim 11 , further comprising a support, separate and disengaged from the dragging device, wherein the guides are mounted on the support.
