Verfahren zur Herstellung eines flachen Umwickelungsmaterials

摘要

A process for manufacturing a flat wrapping material includes the steps of (a) providing a circular roll of wrapping material, (b) compressing the circular roll of wrapping material into a flattened manner where the inner diameter of the circular roll of wrapping material is flattened to form two closely attached symmetric planes, and (c) applying an adhesive on the two closely attached symmetric planes to fixedly secure the two closely attached symmetric planes together.
