Abstract
An arrangement for measuring properties of a moving paper web. The arrangement comprises measuring means for measuring paper properties, in connection with which a plane-like support surface is arranged. The plane-like support surface supports the paper web and extends substantially over the whole width of the paper web in the cross-direction relative to the direction of travel of the paper web. An opening arrangement formed by at least one opening is arranged on the support surface for measuring properties of the paper web.
Claims13
An arrangement in a paper machine for measuring properties of a moving paper web having a predetermined width, which arrangement comprises:
- measuring means for measuring properties of a paper web, and
- an unmoving plane-like support surface for supporting the paper web in connection with the measuring means, the plane-like support surface extending substantially over the whole width of the paper web in the cross-direction relative to the direction of travel of the paper web and defining at least one opening extending substantially over the whole width of the paper web,
- the measuring means being arranged to measure properties of the paper web through the plane-like support surface through the opening.
An arrangement in a paper machine for measuring properties of a moving paper web having a predetermined width, which arrangement comprises:
- measuring means for measuring properties of a paper web, and
- an unmoving plane-like support surface for supporting the paper web in connection with the measuring means in such a way that the paper web is substantially not in contact with the support surface, the plane-like support surface extending substantially over the whole width of the paper web in the cross-direction relative to the direction of travel of the paper web and defining at least one opening therein,
- the measuring means being arranged to measure properties of the paper web through the plane-like support surface through the opening.
An arrangement in a paper machine for measuring properties of a moving paper web having a predetermined width, which arrangement comprises:
- measuring means for measuring properties of a paper web, the measuring means comprising at least one measuring transmitter and at least one measuring receiver, and
- an unmoving plane-like support surface for supporting the paper web in connection with the measuring means, the plane-like support surface extending substantially over the whole width of the paper web in the cross-direction relative to the direction of travel of the paper web and defining at least one opening therein,
- the measuring means being arranged to measure properties of the paper web through the plane-like support surface through the opening.
An arrangement in a paper machine for measuring properties of a moving paper web having a predetermined width, which arrangement comprises:
- measuring means for measuring properties of paper web, and
- an unmoving plane-like support surface for supporting the paper web in connection with the measuring means, the plane-like support surface extending substantially over the whole width of the paper web in the cross-direction relative to the direction of travel of the paper web and defining at least two openings successively in the direction of travel of the paper web,
- the measuring means being arranged to measure properties of the paper web through the plane-like support surface through the opening.
