Foil web cleaning is a decisive process step for high-quality printing, coating and laminating applications. Effective web cleaning for film webs reliably removes dust and particles from film surfaces, which are particularly susceptible to attracting contaminants due to electrostatic charge. The Web Sword Brush Una H-WB 146 provides precise web cleaning by gently removing even the finest contaminants from both the top and bottom of the web during the running process. Two sets of linear brushes, each operating in opposite directions, make contact just a few centimeters beyond the web edge, thereby protecting sensitive edges, even in the case of thin specialty films that are susceptible to scratching. At the same time, the entire web width is cleaned and smoothed towards the edges. Designed specifically for demanding converting applications, the Web Sword Brush delivers reliable foil web cleaning and efficient web cleaning for film webs at high web speeds. The result is cleaner film surfaces, improved product quality, greater process reliability and reduced production downtime.
