The invention relates to a method and a device for winding a band into a coil on a chuck driven into rotation around its axis, by means of a winding assembly including a roll ( 3 ) for applying the band ( 1 ), by an internal face ( 11 ), to the chuck ( 2 ) means ( 62 ) for pushing the roll ( 3 ) towards the chuck ( 2 ) and a bending plate ( 4 ) having a curved face ( 40 ) for guiding the band ( 1 ) along the external face ( 20 ) of the chuck ( 2 ). According to the invention, the application roll ( 3 ) is mounted rotatably on a mobile supporting chassis ( 6 ) whereon rests at least one hydraulic jack ( 62 ) forming a thrust means capable of exerting an adjustable pinching load of the band ( 1 ) between the chuck and the application roll ( 3 ) and the supporting chassis ( 6 ) carries, immediately upstream of the application roll ( 3 ), an additional roll ( 5 ) whereon the band ( 1 ) may rest, taking into account a predictable bending effect ( 1 ) upstream of the application roll ( 3 ), said application ( 3 ) and additional ( 5 ) rolls being driven into rotation so as to exert to the external face ( 12 ) of the band ( 1 ) a driving effect by friction which is added to the effect exerted by the chuck to the internal face ( 11 ).
