Claims

[Scope of claims for utility model registration] (1) A rotational drive device that rotationally drives a workpiece;
A wrapping machine is equipped with a wrapping head device that presses and wraps an abrasive paper on the workpiece that is rotationally driven by a rotational drive device, and the wrapping head device includes a pair of side plates that face each other with a spacer interposed therebetween. and a pair of fulcrum pins suspended horizontally with a gap between both side plates,
a pair of wrapping arms that face each other and whose center portions are pivotally supported by respective fulcrum pins; a shoe that is provided at the bottom of each wrapping arm and faces each other and presses the abrasive paper against the workpiece; 1. A wrapping machine comprising a wrapping arm opening/closing mechanism disposed straddling the upper ends of the wrapping arms and opening/closing the wrapping arm with a fulcrum pin as the center of swing. (2) A claim in which the wrapping arm opening/closing mechanism is a clamp cylinder with one end provided at the upper end of one wrapping arm, and a piston rod that protrudes from and retracts from the clamp cylinder and whose tip is connected to the upper end of the other wrapping arm. The wrapping machine described in item 1.
