This document presents a simple method for determining the angle of a doctor blade on any roll using two templates. Template A is placed with one corner touching the roll and doctor blade, while Template B is placed with one corner also touching the roll and doctor blade. The overlap angle between the templates indicates the doctor blade angle. For smaller rolls, there is a minor error that can be corrected using a scaling on Template B or a calculated error angle formula based on template length and roll diameter. Measuring the angle using this method provides a starting point, and the supplier's guidelines should be checked to ensure the correct doctor blade angle.
New Era Converting Machinery - Gravure Coating Webinarjrd22
The document discusses gravure coating, an industry-versatile coating method. It outlines the webinar on gravure coating, including an overview of the classic gravure coater process and its components like the gravure roll, doctor blade, and impression roll. It also describes improvements like enclosed applicators and quick-change cartridge systems. Variations covered are reverse, offset, and differential offset gravure, as well as pressurized applicators and two-side coating. The versatility of gravure in application range, substrates, coating types, and viscosities handled is highlighted.
Creping
The crepe blade is the point at which the final sheet appearance is created. The geometry of the blade and its application are critical in establishing the best possible end product. Specifically designed for tissue applications, the crepe blade, along with the Yankee against which it operates, is the heart of the process.
The doctor holder uses a special pneumatic loading arrangement to load the blade against the Yankee cylinder and has a “flexible finger” type backing. The mechanical lock prevents collision of the holder with the cylinder when there is no blade in place. For certain applications and upon request, a stiff holder can be substituted.
Angle adjustment
The doctor assembly is adjustable for different applications and end product properties. The entire assembly can be rotated on the assembly journal by means of a jacking bolt that changes the position of the assembly relative to the loading cylinder stroke.
At a glance
Flexible holder ensures even application of the creping load.
Adjustable angular position allows flexibility for different products and properties.
The document provides an overview of tissue machine operator training, focusing on crepe tissue production and the factors that influence creping. It discusses how increasing percent crepe through differences in yankee and reel speeds can improve sheet properties like bulk and softness. It also explains that coatings are applied to the yankee dryer to hold the sheet during creping and help build a good roll, while release aids facilitate sheet removal and influence properties. Common problems and methods for adjusting crepe, coatings and release aids to protect the dryer surface and meet sheet specifications are described.
