KELVA Inventor of Web Cleaning


How to free production environment from dust and benefit from efficiently removing debris when producing and finishing corrugated boards?

With increasing pressure on boxmakers from customers to produce top quality work with little room for error, production processes causing high dust loads and contanimation potential like wind/unwind, cutting, slitting/scoring must be cleaned from dust to assure product quality and production efficieny.

We help you in analyzing the dust-load and how to eliminate it

Save the quality of your product, save the life-time of your machines, save the health of your employees!

The risk of damaged board surfaces by debris will be eliminated. Your whole production environment will be clean and thus a high quality of your end-product will be assured. If the boards continue to be printed, their dust-free state will highly reduce the wash cycles within the printing process. Less dust in the production location will also improve health environment of your operators.

KELVA web cleaning equipment can be easily installed into all types of R2R-production machines, be it new machines or as retrofits in existing production systems.

KELVA Non-Contact Web Cleaning Principle

During non-contact web cleaning the surface of the material won’t be physically touched. Instead a combination of underpressure, blown air and ionisation is used to remove any loose particle from the surface of the web.

This is the ideal method for extracting high dust loads and the variety of particles typical for corrugated board production.

A KELVA non-contact cleaning system includes a web cleaner with integrated antistatics, a filter/fan unit and connecting duct system.

KELVA Web Cleaner Head

Web cleaner heads for corrugated production follow the non-contact cleaning principle and remove the debris from both sides of corrugated board. The web cleaning system offers an integrated anti-static device, infeed plate and grid.
Automatic height adjustments allows cleaning of sheets with various thicknesses. Configurations can be adapted to specific demands and web width.

KELVA Filter-/Fan Unit

Filter-/fan units consist of two parts: The upper part includes the ventilator providing the blowing air and the suction air for the whole web cleaning system. In the lower part the filter plates are installed for collecting the dust. They will be automatically cleaned by a jet pulse de-dusting system.The dust finally falls down into a dustbin. The filter area can be adapted to bigger dust loads and various web widths.

KELVA Non-Contact System

KELVA non-contact cleaning systems include a web cleaner head incl. integrated antistatics, a filter/fan unit and a connecting duct system. The cleaner head ideally is installed before and after critical processes for extrac-ting the dust and particles and thus making clean the product surface for a next production- or finishing step. The filter/fan can be installed farther away, dependig on the space conditions on site.
