PURPOSE:To retain a large quantity of strips with a small-sized device by winding the strips in layers into the form of plural loops with clearances on one of a couple of pinch rollers, and providing a direction changing roller as against the pinch rollers. CONSTITUTION:A strip 12 is wound on a couple of driving rollers 11a and 11b in plural layers, and the strip 12 is elastically pressed against the driving rollers 11a and 11b by a couple of presser rollers 13a and 13b. The strip 12 wound on the driving rollers 11a and 11b forms plural loops 15, and a clearance 16 is formed between the loops 15. In addition, a direction changing roller 14 which is inclined to the driving rollers is provided freely rotatably between the driving rollers 11a and 11b, and the strip 12 at the innermost circumference is wound round the direction changing roller 14. The aging device for the strip which is compact in structure can be obtained in this way, and a large quantity of strip 12 is retained in the device. |
