Dryer section water-jet tail cutter


Nanotechnology - enhanced doctor blades


began F


researching nanotechnology and its


applications to current doctoring products.


Nanotechnology had already been applied to other products such as hockey sticks, tennis rackets, and surfboards. Dr. Mike


Draper,


composites manager at Kadant UK, and the research and development team developed a resin made from nano- particles that when paired with doctor blade raw material, creates a stronger and more resistant doctor blade less prone to


chipping and delamination.


The patented nanotechnology- enhanced doctor blades have delivered exceptional results in field trials on tough applications that previously used standard composite blades that were notoriously short- lived. The latest advances in ‘nano- blades’ have proven to be a perfect fit for these challenging doctoring applications.

RESISTANCE TO CONTAMINATION


Nanotechnology-enhanced doctor blades have a vigorous protection against chemical and solvent contamination.


REDUCES ENERGY LEVELS


Lower friction co-efficient directly contributes to energy saving results.


HIGH PERFORMANCE


Polymeric resin matrix has been beneficially manipulated at a molecular level to produce a product that increases the strength of scraper blades. This results in a better scraper system for applications and a longer life span on the blade.


RESISTANCE TO DELAMINATION


Elevated inter-laminar bonding results in greater resistance to delamination of blades.


NEW BEVEL EDGE DESIGN


The sharp leading edge design enhances cleaning in arduous applications. The integrity of the design also contributes to a longer lasting sharp edge.

equipped with fixed or rotating blade tail cutters that can provide an acceptable cut quality under well- defined operating conditions - limited basis weight range, high paper dryness and, importantly, assuming the use of a well sharpened blade. Weingrill, represented in the UK by Jarshire Limited, has developed the HP-Waterjet, the working principle of which is based on high pressure water usage. It comprises one pumping station providing high pressure water and one nozzle to turn the applied pressure into a high velocity water jet. Paper can then be ‘cold cut’ without any change to its chemical and physical properties. Suitable for all kinds of paper and board, including coated grades, the HP-Waterjet has been designed to provide an alternative tail cutting system to traditional blade tail cutters and is an excellent tool to better manage the tail threading process. As there is no mechanical contact with the paper, it provides a dust- and drag-free cut with reduced threading downtimes. Also, non-contact cutting eliminates inevitable wear and replacement and associated time losses related to service and maintenance of rotating or fixed blades. As lower cutting forces are exerted on the


paper, stronger sheet edges and reduced web breaks are further advantages.


HP-Waterjet advantages include:- • Not subject to wear so does not require continuous service


• Eliminates airborne dust, significantly reducing paper breaks and improves environment


• Narrow size of water jet guarantees efficient paper cutting at high speed without disturbing or breaking the sheet


• Due to lower cutting force, cutting operation is faster and smoother, improving efficiency


• No physical adjustments required - not influenced by profile variations or sheet fluttering


• Cutting head has more flexible mounting options including dryer fabrics or in open draws


• Compact cutting device - can be installed in relatively old and narrow dry end fabric runs


• Produces sharper, stronger sheet edges than a knife or rotary blade
