Yankee cylinder drive units feature new, innovative technology to meet the requirements of today's high-speed tissue machines. The Yankee cylinder drive features a unique pre-load arrangement of the main bearing, optimising load distribution, stabilising the operation of the Yankee gear unit and consequently extending bearing life.

ANDRITZ offers three standard diameters of the PrimeDry Steel Yankee for tissue pro-duction: 12 ft. (3,658 mm), 15 ft. (4,572 mm) and 16 ft. (4,877 mm). Paper width on the Yankee can be up to 5,600 mm. ANDRITZ also offers steel Yankees for paper and board, MG, and tobacco machines. Cast iron Yankees, manufactured in Germany, are still part …

The Yankee dryer is the heart of a tissue machine. It needs to retain a stable surface for creping, withstand high loads of creping and cleaning blades, and cope with occasional dry running situations. Optimized thermal sprayed coatings, often referred to as Yankee metallization, are compatible with the organic Yankee coating and resistant to chatter. …

Effective and Consistent Convective Drying ensured by the proper Hood-Cylinder Gap (Impingement Distance). Distinct Impingement Holes alignment and Open Area guaranteeing maximum uniform drying rate. Uniform CD temperature and impingement velocity ensuring even cross-machine drying for optimum paper quality.

The Yankee Dryer can be defined as the heart of a machine dedicated to the production of Tissue paper.This huge internally heated cylinder allows, together with the hoods, to remove by evaporation most of the water remaining in the paper sheet after passing through the press section.In this way, the humidity percentage of the sheet goes from 60-65% to …

Ultimately, the tissuemaker wants a Yankee cylinder with as uniform a Yankee thermal profile as possible. This means both in the cross direction (CD) and the machine direction (MD). ... S&C systems …

Yankee Cylinder Gearboxes 15003 KUMERA 3 Presentation of gearboxes, types and their characteristics Optimized design for tissue-making processes The Yankee gear unit series is built on the proven foundation of Kumera's design and manufacturing system, combining decades of extensive experience with trusted quality.

OVERMADE's Manufacturing capability includes: operating pressure of 5 or 8.5 and 10 bar, plain or ribbed inner surface, pressure vessel coding available for all Countries. The diameter of the OVERMADE Yankee goes from 3200 mm up to 4877 mm, without ...

Dewatering of the paper sheet on a conventional tissue machine is normally accomplished by using a combination of mechanical and thermal processes. Following formation of the sheet, the dry solids content is initially increased to around 40-45% by pressing and vacuum forces. This is followed by evaporation in the Yankee and hood to …

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.

An object of this invention is to provide a Yankee cylinder, more specifically a steel Yankee cylinder, using a simple and safe construction system. The yankee cylinder according to the invention is defined in claim 1.
