Claims

[Scope of Claim for Utility Model Registration] (1) A roll body for winding paper, film, etc. is sandwiched so that it can be attached and detached by moving the support shaft from both ends;
In addition, in the structure for applying brake torque for tension, the support shaft is provided with grooves in three or more places in the axial direction, and the grooves are formed continuously in parallel from a position downward from the slope part, and the grooves are formed continuously in parallel from a position downward from the slope part, and a shaft provided with a brim, and one of the cylindrical bodies provided with a brim that abuts the brim and is larger than the inner diameter of the roll body;
A cylindrical shaft has a hole bored in the axially intermediate portion thereof to engage with the groove, a roller rotating through the groove is pivotally supported in the hole by a pin at the tip, and the other side is attached to the inner wall of the roll body. A convex metal fitting is provided with sharp teeth for transmitting torque between the roll body and the support shaft, and the sharp teeth bite into the inner diameter of the roll body when the roller moves from the parallel groove to the slope groove. A spring is arranged to always press the protruding metal fitting in the axial direction, and a guide hole is provided to allow the protruding metal fitting to rise or fall, and it is flush with the outer circumferential surface of the cylindrical shaft to prevent these from protruding from the cylindrical shaft. A guide fitting is provided as a surface, a recess is provided in the axis of the cylinder, a spring is built into this recess, and the shaft is fixed to the cylindrical shaft with a bolt or the like so that it is compressed at the tip of the shaft when the shaft is inserted into the cylindrical shaft. A structure of a roll support shaft, characterized in that it is integrally constructed with a tip shaft. (2) The shape of the groove is such that the groove is parallel to the upper end of the slope, and there is a gap between the inner wall of the roll body and the tooth tips on the lower end side, so that the teeth gradually form on the inner wall of the roll body at the slope part. A structure of a roll support shaft according to claim 1, which is a registered utility model, characterized in that the tip of the shaft bites into the shaft, and the groove on the upper end side cuts into the shaft to the maximum. (3) Using rolling elements such as balls instead of rollers, providing a space for the rolling elements to rotate, and incorporating a spring that presses the groove slope in the upward direction.
A structure of a roll support shaft according to claims (1) and (2) of the utility model registration, characterized in that each of the parts is provided on a protruding metal fitting and constructed integrally. (4) Utility model registration claims paragraphs (1) and (2) characterized in that the protruding metal fittings are provided with alternating slits so as to provide a spring action in the inner diameter direction of the roll body. and the structure of the roll support shaft described in paragraph (3).
