Abstract

DC60 Control method for controlling a flipping dryer (1) for drying wool fabrics (5). The control method comprises the steps of: loading the wool fabric (5) into the drum (3) of the flipping dryer (1); feeding a stream of drying air into the drum (3); rotating the drum (3) at a first rotational speed (n1) greater than a second rotational speed (n2) such that the centrifugal acceleration of the internal surface of the drum (3) is equal to the acceleration of gravity; thus the wool fabric (5) is pressed by a centrifugal force against the internal surface of the drum (3) in a manner opposite to that of falling into the drum (3); and periodically stopping the rotation of the drum (3) by bringing the rotational speed (n) to zero, followed by accelerating the drum. (3)Return to first rotation speed (n1) to rearrange the fleece (5) inside the drum (3). Control method for controlling a flipping dryer (1) for drying fleece (5). The control method includes the steps of: loading the fleece (5) into the drum (3) of the flipping dryer (1); introducing a stream of drying air into the drum (3); rotating the drum (3) at a first rotation speed (n1) greater than the second rotation speed (n2) such that the centrifugal acceleration of the interior surface of the drum (3) is equal to the acceleration of gravity; thus the fleece (5) is pressed by a centrifugal force against the interior surface of the drum (3) in a manner opposite to that of falling into the drum (3); and periodically stopping the rotation of the drum (3) by bringing the rotation speed (n) to zero, followed by accelerating the dryer (3) back to a first rotation speed (n1) to rearrange the fleece (5) inside the drum (3).
