<p>Device to switch fabrics in napping machines (11), which is suitable to displace laterally in a desired manner a fabric (14) being fed, the axis (29) of feed of which is substantially perpendicular to the axis of the napping drum (12), the device comprising at least a first lengthwise intake bar (20) and a second lengthwise output bar (21) and including at least one powered roll (22) positioned between the first bar (20) and second bar (21), the first bar (20) and the second bar (21) and the powered roll (22) having a first position with their relative axes (26, 28, 27) substantially perpendicular to the axis (29) of feed of the fabric (14) and at least one second position with their relative axes (26, 28, 27) inclined by a relative angle ( alpha , gamma , and beta ) in relation to the line perpendicular to the axis (29) of feed of the fabric (14). <IMAGE></p> |
