PURPOSE:To obtain a strip foil which has the identical brilliance, feeling and etc. (to be used for weaving etc.) of both sides by folding a strip sheet in two so that a reverse side falls on the other and by sticking them together. CONSTITUTION:In order to fold in two in its longitudinal direction a strip shaped sheet 2 which is flat and unfolded, by using guide rollers 1, 1' that are arranged in parallel with the surfaces equivalent to the surfaces of the right and left segments, and a guide bar 2 which is extended along the centerline of the twofold, the strip sheet 2 is folded in two and the overlapping reverse sides are struck together. Thus, a two-ply strip foil of identical brilliance on both sides is easily obtained. |
