Abstract:
The invention relates to a suction device ( 15 ) for use in a papermaking machine ( 1 ). The suction device ( 15 ) has a length (L) in the machine direction that extends from a first end ( 16 ) to a second end ( 17 ). The suction device ( 15 ) further has a surface ( 18 ) which, during use of the suction device ( 15 ) in the papermaking machine, will be facing a permeable fabric ( 4, 6 ) passing the suction device during operation such that this surface ( 18 ) is a fabric-facing surface ( 18 ). The fabric-facing surface ( 18 ) has a first part ( 19 ) which begins at the first end ( 16 ) of the suction device ( 15 ) and extends towards the second end ( 17 ) but ends before the second end ( 17 ) of the suction device. The first part ( 19 ) of the fabric-facing surface ( 18 ) is formed by a plurality of planar surfaces ( 23 ) which constitute end surfaces of a plurality of solid elements ( 21 ) and lie in the same plane such that, during operation, they can contact a fabric ( 4, 6 ) gliding over the fabric-facing surface ( 18 ) along a straight path. The solid elements ( 21 ) are separated from each other along the length of the suction device ( 15 ) such that channels ( 24 ) are defined between the solid elements ( 21 ), and the suction device ( 15 ) can be connected to at least one source of underpressure ( 26, 27 ) in such a way that the at least one source of underpressure ( 26, 27 ) is in communication with the channels ( 24 ) between the solid elements ( 21 ) such that, when the suction device ( 15 ) is used and the permeable fabric ( 4, 6 ) runs over the fabric-facing surface ( 18 ), the suction device ( 15 ) can act on the permeable fabric ( 4, 6 ) through the channels ( 24 ) and draw the permeable fabric ( 4, 6 ) towards the fabric-facing surface ( 18 ). The first part ( 19 ) of the fabric-facing surface ( 18 ) is followed by a second part ( 20 ) of the fabric-facing surface ( 18 ). The second part ( 20 ) of the fabric-facing surface ( 18 ) is a surface ( 33 ) formed as an end surface of a final solid element ( 22 ) which does not lie in the same plane as planar surfaces ( 23 ) belonging to the first part ( 19 ) of the fabric-facing surface ( 18 ) but is spaced from that plane such that, when the permeable fabric ( 4, 6 ) passes over the suction device ( 15 ), the permeable fabric ( 4, 6 ) will not contact the final solid element ( 22 ). The final solid element ( 22 ) is separated from a preceding solid element ( 21 ) such that a final channel ( 25 ) is defined between the final solid element ( 22 ) and the preceding solid element ( 21 ) and the final channel ( 25 ) being capable of communicating with at least one source of underpressure ( 26, 27 ) for the final channel ( 25 ). The invention also relates to a machine using the inventive suction device.

Claim (Index 11):
A papermaking machine according to  claim 10 , wherein:\n the drying section comprises a through-air-drying cylinder ( 9 ) and the endless permeable fabric ( 6 ) is a through-air-drying fabric which is arranged to wrap a part of the through-air-drying cylinder ( 9 ), and the suction device ( 15 ) is placed within the loop of the permeable fabric ( 6 ) such that it can act on the permeable fabric ( 6 ) and on a fibrous web (W) carried by the permeable fabric ( 6 ) and separated from the suction device ( 15 ) by the permeable fabric ( 6 ), the suction device ( 15 ) being placed upstream of the through-air-drying cylinder ( 9 ) such that it acts on the permeable fabric ( 6 ) before the permeable fabric ( 6 ) reaches the through-air-drying cylinder ( 9 ), the fabric-facing surface ( 18 ) of the suction device ( 15 ) having an orientation that is more vertical than horizontal.
