Abstract (en)
[origin: US2008053632A1] The invention relates to a device ( 11 ) for stabilising the transport of a material web ( 12 ) on the upper face of an air-permeable machine clothing ( 10 ), in particular a fibrous web. The device is located on the underside of the machine clothing directly upstream of an intake nip in the direction of travel ( 17 ) of the web, said nip being formed by a roll ( 5 ) and the machine clothing, and comprises a first negative-pressure zone ( 19 ) and at least one vacuum opening ( 20 ) that faces essentially in the opposite direction to the direction of travel of the web, communicating with the first negative-pressure zone of the device. This permits the boundary layer ( 23 ) of air that is carried along by the underside of the machine clothing to be at least partially sucked from said clothing into the first negative-pressure zone.
