Claims

[Scope of Claim for Utility Model Registration] (1) A long rubber sheet cut out with a certain width is hung down from the front side, and the hanging rubber sheet is swung back and forth at predetermined length intervals. A device that folds the rubber sheet into a yard-fold shape while folding the sheet alternately and in opposite directions, and includes a rotating body rotatably provided around an axis perpendicular to the direction in which the rubber sheet travels, and a drive that rotationally drives the rotating body. a device, which is provided on a rotating body at a position away from the axis and parallel to the axis, and rotates with the rotating body while receiving the cut out long rubber sheet in the width direction; a plurality of guide parts that sequentially droop the rubber sheet and at the same time change the drooping position of the rubber sheet according to the rotational angular position of the rubber sheet, and the plurality of guide parts are respectively different from the axis. In addition to being provided at distance positions, guide portions having a long distance from the axis and short guide portions are alternately arranged at predetermined intervals in the rotation direction of the rotating body, and the distances of the plurality of guide portions from the axis are A folding device for a long rubber sheet, characterized in that the folding position of the rubber sheet is sequentially changed according to the change. (2) The rotating body has a rotating shaft that rotates around the axis, and four sets of arms that extend radially from the rotating shaft at 90 degree intervals and have different lengths, and among these arms, long ones and short ones are arranged alternately in the rotation direction of the rotating body,
Further, a guide bar parallel to the rotation axis is provided at each end of each of the arms, and the guide bar serves as a guide portion for changing the hanging position of the rubber sheet. The folding device described.
