Uhle boxes, sometimes known as felt cleaning assemblies, dewatering elements, drilled covers, or Uhle pipes, and Uhle box covers are an integral part of every paper machine’s press section. The Uhle box is designed to enhance uniform cross-directional dewatering and cleaning and minimize energy consumption on the press section of a paper machine. Uhle boxes are available with optional fixed, manual, or automatic Uhle box rotators. Uhle box rotators provide a safe and easy method to rotate the suction pipe for inspection, change the wear surfaces, and remove pitch and stickies from the covers. Kadant offers three polyethylene materials to construct Uhle box covers or strips, the Durwear™ HTb, Durwear A+, and Durwear XW, and ceramic options.
