Title:
PAPER QUALITY MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2001349824
Kind Code:
A
Abstract:

To provide a paper quality measuring device capable of measuring the rigidity of a fed paper sheet at least in the feed direction thereof.

The paper sheet fed along a feed passage is pressed over the whole width thereof by an MD pressure roller 21 to be deformed in the feed direction thereof. For this reason, the reaction force corresponding to the rigidity of the paper sheet in the feed direction acts on the MD pressure roller 21, and the rigidity of the paper sheet in the feed direction thereof is measured by a strain quage 22. Accordingly, the rigidity of the paper sheet in the feed direction thereof can be used in the quality control of the paper sheet to enable proper quality control.
