Abstract
Equipment for fabric guiding in a paper machine has a fabric (10) and rolls (12–18) adapted to support it. In connection with the roll (17) end there is arranged equipment comprising a stand (19) and a nip guard (26). The stand (19) includes a transfer base (20) as well as transfer equipment (22) for moving the transfer base (20). The equipment further comprises an edge detector (23) for the roll (17) arranged on the opposite side of the fabric (10), for which edge detector there is a vertical bracket (25) arranged in the stand (19). The vertical bracket (25) and the nip guard (26) form an integrated sheet-metal construction.
Claims9
An apparatus for fabric guiding in a paper machine comprising at least one fabric arranged as an endless loop as well as rolls adapted to support it, wherein the rolls include a first roll, and wherein at the end of at least the first roll there is arranged equipment that includes:
- a stand adapted to attach to a paper machine frame;
- a nip guard in the stand at gaps formed by the first roll and the fabric;
- a transfer base movably adapted to the stand;
- transfer equipment for moving the transfer base in relation to the stand;
- at least one edge detector for the first roll, arranged on the opposite side of the fabric, for determining the fabric position in the axial direction of the first roll;
- and
- a vertical bracket arranged to the stand for the edge detector, whereby the first roll end supported by the transfer equipment is adapted to be set according to the edge detector by the transfer equipment for keeping a desired fabric position at the rolls, characterized in that the vertical bracket and the nip guard form an integrated sheet-metal construction.
A paper machine with an apparatus for fabric guiding, comprising:
- a plurality of rolls including a first roll, the first roll rotating about an axis and having an end, the direction of the axis defining an axial direction;
- at least one fabric arranged as an endless loop supported on the plurality of rolls, the at least one fabric passing over the first roll, wherein gaps are defined between portions of the fabric and the first roll;
- at the end of the first roll there is arranged:
- a stand attached to a paper machine frame;
- a transfer base movably adapted to the stand;
- transfer equipment for moving the transfer base in relation to the stand;
- at least one edge detector for the first roll, arranged on the opposite side of the fabric, for determining the fabric position in the axial direction of the first roll;
- and
- an integral sheet-metal construction having portions defining a nip guard in the stand at the gaps formed by the first roll and the fabric and a vertical bracket mounted to the stand, the at least one edge detector being fixed to the vertical bracket, wherein a first roll end supported by the transfer equipment is set according to the edge detector by the transfer equipment for keeping a desired fabric position at the rolls.
