Document Type and Number:
Japanese Patent JP2730989
Kind Code:
B2
Abstract:
To determine measurements such as basis weight and caliper of a travelling sheet during production, the sheet is repeatedly traversed with a scanning sensor and, during each traverse, measurements are taken at a plurality of slice locations. Then, a sedries of reference locations are selected which are spaced apart in the machine direction along the sheet surface. Then, for selected slices, measurement values are estimated based upon actual measurements taken at locations on the selected slices which are not spaced in the machine direction at the same spacing as reference locations.
