Estimating the term…
The invention relates to a method for manufacturing a container with a shell made of a fiber-based material, wherein the container has an open end with an opening and a closed end, wherein a flange section with a sealing surface is formed on the shell at the open end, comprising the steps: preforming the flange section by forming a spiral winding by rolling a free edge section of the shell outward, and finishing the flange section by flattening the spiral winding with an ultrasonic device comprising an ultrasonic sonotrode and an anvil, wherein the ultrasonic sonotrode for flattening the spiral winding is arranged on a side of the spiral winding in the direction of the closed end and the anvil is arranged on an opposite side of the spiral winding. The invention further relates to a device for manufacturing the container.
