Claims

[Claims for Utility Model Registration] 1. A roller body is constructed by arranging a plurality of long and thin blades in a cylindrical shape around a rotational axis and supporting each blade so as to be movable in the axial direction, and the roller body is connected to a pair of left and right roller bodies. In the expander roller, each blade of the left and right roller bodies is arranged coaxially and is provided with a blade reciprocating mechanism at the end of the left and right roller bodies for reciprocating each blade in one rotation period of the roller body. Meandering characterized in that at least one of the movement mechanisms is provided with an actuator that increases or decreases the maximum movement width of the blade of the blade reciprocating mechanism in accordance with the deviation in the width direction of the sheet material wound around the left and right roller bodies. Modifiable expander roller. 2. The actuator is provided only in one blade reciprocating mechanism of the left and right roller bodies, and the blade reciprocating mechanism is connected to the other blade reciprocating mechanism via a connecting rod so that the maximum blade movement width is alternately increased or decreased. The expander roller according to claim 1 of the registered utility model. 3. The expander roller according to claim 1, wherein the actuator is provided in each blade reciprocating mechanism of the left and right roller bodies. 4. Utility model registration claims 1 to 3, in which the actuator is driven in a direction to correct the deviation in conjunction with an edge detection mechanism that detects the deviation in the width direction of the sheet-like material wound around the left and right roller bodies. The expander roller described in any of the above. 5. The expander roller according to any one of claims 1 to 4, wherein the actuator is an air cylinder. 6. The expander roller according to any one of claims 1 to 4, wherein the actuator is an electric motor.
