Title:
紙および連続ウェブ・スキャナのエアワイプおよびシート・ガイド温度制御
Document Type and Number:
Japanese Patent JP2014506303
Kind Code:
A
Abstract:
Paper and continuous web scanners operate at varying and high temperature conditions. Regulating the temperature within the measurement gap between dual scanner heads during measurement and calibration modes of operation by employing air wipe and sheet guide temperature control assures consistent and accuracy sensor measurements of sheet characteristics. Air wipes blow pre-heated air into the measurement and the sheet guides are heated. The air temperature fluctuations that otherwise caused significant adverse effects on the sensors that measure, for example, the basis weight, ash content, and thickness of the moving sheet, are eliminated.
