ER-WE-PA GmbH, Davis-Standard’s German subsidiary, recently installed a custom five-roller calender unit for a global adhesive tape manufacturer. Designed to customer specifications at our recently ISO-9001-2015 certified ER-WE-PA facility in Erkrath, this machine features a unique design to accommodate layer thickness precision, reproducibility, processing flexibility and operator accessibility. ER-WE-PA is supporting converting customers by engineering innovative solutions for a wide range of applications, says Michael Krämer, Managing Director of ER-WE-PA. “Specifically for this customer, we took proven technology and customized various components to address sensitive adhesive processes. Even when subjected to significant shear forces, this machine is equipped to consistently control gap size within the micron range during production. The customer is very pleased with the performance in terms of increased capacity of current products and the potential for future growth.”
The calender unit is capable of supporting a variety of materials including foams, fabrics, PET or MOPP, or coated products using five different application techniques. The calender rolls are individually adjustable in longitudinal and transverse directions, and the machine design enables a quick exchange of each pair of rolls. This makes it possible to process variable layer thicknesses with different viscosities. All essential machine functions and process parameters are automatically controlled.
