A DEVICE COMPRISING A MULTILAYER STRUCTURE AND ROLLERS

摘要

The invention relates to a device (35) comprising a multilayered structure (35a) with a first portion and a second portion wherein the first portion is conceived to be rolled about a first roller (38), said device comprising a second roller (39) for receiving the second portion for at least partially counteracting the effects of mechanical strain induced in the multilayered structure upon said rolling. The first roller (38) is rotated in a first direction, whereby the second roller (39) is rotated in a second direction. Preferably, the diameters of the first roller (38) and the second roller (39) are equal. Alternatively, the edge portions A, B of the multilayer structure (34a) are suitably interconnected by stoppers (33a, 33b) for preventing creeping.
