Doctoring

Doctoring? Roll cleaning? Scraping? Flaking? Continuous belt cleaning? These are terms for a similar process used differently depending on the industry, but the product’s purpose is the same–to clean or remove contaminants from a roll surface. A doctor blade, roll cleaning blade, scraper blade, or flaker blade is any material in stick form that is run against a roll and is used to keep the roll clean. Materials can be just about anything like composite, metal, or plastic.

Synthetic Fibers

Synthetic fibers are also known as polyester fibers and carbon fibers. During the polyester fiber and carbon fiber manufacturing process, the fibers develop fuzz. They can break and wrap while being pulled across rolls and through ovens before finally arriving at the sizing bath. 

Kadant have contributed significantly to improving the safety and efficiency of fiber production, by designing advanced roll cleaning solutions that allows the user to safely manage fiber as it contacts and pulls across a roll or other rotating equipment.

Roll Cleaner Assemblies

Filtration

Filtration products, such as pressure filters and water resource recovery strainers, are used to remove contaminates from liquid in process industries. A filtration system will contain a filter media which is used to separate unwanted particles from the substance being filtered. The filtration process can be intermittent or continuous providing high cleaning efficiency and easy maintenance.  

To maximize performance, filtration systems are chosen and designed for the application. Common applications include fresh water, process water recycling, dyes and additives, mechanical seal protection, chemicals, DAF filtrate, clearleg save-all water, overflow cylinder vat water, vacuum pump seal water, felt hair removal from press section, fiber recovery from u-drains, solids separation, thickening, fiber scalping, removal of sand from rivers and lakes, cooling towers, pump protection, steel mill water recycling, and spray nozzle protection.

Kadant doctoring, de-watering, formation, fabric cleaning and conditioning, and filtration, products, technologies, and services enhance sheet properties, reduce energy and water consumption, and improve long-term sustainability.

Doctoring

Doctoring double doctor systemis an important part of the pulp and paper making process with several functions such as removing water and contaminants from the roll surface, cleaning and conditioning the roll surface, and sheet shedding during sheet breaks or threading operations.

A doctoring system consists of the doctor back (i.e., a beam), a doctor blade holder, a doctor blade, and components to mount the system to the machine’s framework. The doctor blade is the component that performs the functions of removing water, debris, and contaminants; cleaning and conditioning the roll surface, or shedding the sheet. Blades are wearing parts   and need to be replaced on a regular basis depending on the application.

Doctoring can prevent material from wrapping the roll surface. In applications where a continuous web of product is being produced such as paper, a web break can cause the material to wrap around the roll. Doctoring systems help direct the product, sheet, or web to the next section of the machine. There are also specialty doctoring applications like creping of the sheet, coating, and metering applications.

Forming

Forming refers to a process and a section of a paper machine. The forming section of a paper machine is where the first stage of building the mat of paper takes place. Water and fiber are presented from a nozzle referred to as the headbox onto a moving filter medium known as a forming fabric. 

Forming products are the devices and equipment that support and remove the water throughout the development of the web of paper until it reaches a state that will allow it to transfer to a pressing stage. Forming products consist of forming boards, foil blades, deckles, deckle boards, wear surfaces, low vacuum units, high vacuum units, and top formers.
