Abstract
An apparatus for continuously accumulating a travelling metal strip or wire-like material in an accumulating space provided within a continuous annealing line, diffusion coating line or the like for performing a winding or re-winding operation for a time corresponding to a treating time. The apparatus has a pair of winding reel devices on opposite sides of the path of the material through the accumulating space, each having a rotary shaft and at least one arm extending radially of the rotary shaft and rotatable around the rotary shaft. Each arm has a folding back roll freely rotatably mounted on the outer end of the corresponding arm, and extending parallel with the axis of the rotary shaft. The locus of the axes of the folding back rolls on one reel device intersects the axis of the rotary shaft on the other reel device. Each of the rotary shafts has a reel receiver thereon for receiving the folding back roll on the other reel with the material therearound. The strip of material is engaged by the folding back roll and moved into the roll receiver to be held thereby, and the corresponding rotary shaft is rotated to wind up the thus folded back strip. At the same time, a portion of the double wound strip on the other reel device is unwound, and the remainder is drawn out from the apparatus. When the desired amount is wound up on the one reel device and the corresponding amount has been completely unwound from the other reel device, the operation is reversed.
