Renewing the Technology Center with WEKO
Customers have the opportunity to test coating and drying processes for different products and with different materials, and they can optimise all processes and parameters before investing in a new production line. Thanks to continuous internal research and development as well as cooperation with universities, institutes and key suppliers, the Technology Center is always at the cutting edge of technology.
Renewal of the remoisteningRecently the remoistening of WEKO was renewed and replaced by a WEKO-SIGMA rotor carrier to offer customers the best possible results. Paper fibres that have shrunk due to drying, lead to wavy and curled papers with an unsightly look. Targeted remoistening relaxes the paper fibres. This ensures flatness, avoids static charges, ensures high product quality, and maximises the processing speed.
Paper is a “living” product that cannot be standardised and whose behaviour can never be fully predicted in the different processing processes. After all, paper essentially consists of cellulose. When moisture is absorbed, these fibres expand by up to 25 percent in width and only insignificantly in the longitudinal direction. In the same way they contract when moisture is lost, for example due to the effects of heat.
