Patent ID: 8910398

Claim:
A drying system of a coated continuous film comprising a plurality of conveyor rollers ( 3 ) supported at ends by a first support ( 5 ) and a second support ( 6 ) mounted on side members ( 4 a , 4 b ) of the drying system, wherein said conveyor roller ( 3 ) comprises: a guide cylinder ( 7 ) of the coated continuous film; a first support shaft ( 9 ) integral with a first end ( 11 ) of said guide cylinder ( 7 ) housed in the first support ( 5 ); a second support shaft ( 10 ) placed at a second end ( 12 ) of said guide cylinder ( 7 ) housed in the second support ( 6 ) and having a first end ( 14 ) adapted to couple with said second end ( 12 ) of the guide cylinder ( 7 ), and wherein the first support ( 5 ) comprises: a support flange ( 28 ) integral with the side member ( 4 a ) of the drying system by means of fixing bolts ( 43 ); a flange ( 29 ) connected to said support flange ( 28 ), there being provided a sliding device adapted to allow said flange ( 29 ) to slide toward and away from said support flange ( 28 ) along a direction parallel to the axis of the conveyor roller ( 3 ); an elastic device which exerts an axial force on the flange ( 29 ) in a direction moving said flange ( 29 ) toward the support flange ( 28 ), the axial movement of said first support shaft being prevented with respect to said flange ( 29 ), so that the guide cylinder ( 7 ) is maintained in contact with said second support shaft ( 10 ), and wherein the support flange ( 28 ) is arranged on the side member ( 4 a ) of the drying system so that the guide cylinder ( 7 ) together with the first support shaft ( 9 ) and the first support ( 5 ) can be removed from the drying system by sliding the guide cylinder ( 7 ) through the side member ( 4 a ).
