Title:
COLORED DRYER CANVAS FOR PAPERMAKING
Document Type and Number:
Japanese Patent JP2001159087
Kind Code:
A
Abstract:

To obtain a colored dryer canvas capable of easily responding correctly to both sensors of a reflection light type sensor for detecting a paper break and a reflection light type sensor for detecting the meandering of the canvas.

This dryer canvas is used in a dryer part of a papermaking machine equipped with the reflection light type sensors detecting each of the differences as a paper break-detecting means and canvas meandering-detecting means and having the above detecting means using different light source wave lengths for each of the reflection light type sensors, and is provided by coloring the canvas with hues having ≥60 % high reflecting ratio wave length zone and ≤20 % low reflecting ratio wave length zone in the case of measuring the hues by using a spectroscopic measuring device in 380-780 nm wave length zone of the spectroscopic reflection curve.
