Abstract (en)

[origin: EP0855354A2] A web (10) is wound on a core (16) into a web roll (17) while being traversed in a width direction of the web (10) at a predetermined cycle and amplitude so that each end face of the web roll (17) can have corrugations of predetermined form. The web (10) is wound with both edges thereof being staggered. Thus, if the thickness of the web (10) is uneven in the width direction, thick parts and thin parts are alternately layered, so that the web (10) can be wound under an even pressure, and the web roll (17) can have good form. Since the end face of the web roll (17) has the corrugations of predetermined form (for example, sawtooth form), the web (10) can be prevented from slipping on the web roll (17), and the web roll (17) can be suitable for transportation. <IMAGE>
