<P>PROBLEM TO BE SOLVED: To realize a brake mechanism which prevents occurrence of slacks of a sheet drawing portion occurring by inertial rotation of a sheet roll while drawing remains suspended in sheet drawing in an aspect where drawing from the sheet roll pivoted by a rotary shaft and suspension are repeated. <P>SOLUTION: In the brake mechanism where a base end side is pivoted by a rotary shaft parallel to the rotary shaft of the sheet roll to paste a brake pad 1 to a sheet roll side in front of a brake lever extending in a rotation direction of the sheet roll, and to keep this brake pad elastically pressed against the outer periphery face of the sheet roll by a spring mechanism against the brake lever, there is provided a portion where a width of a sheet roll rotary shaft direction becomes greater regardless of continuation or discontinuation as the same rotation proceeds on a face coming in contact with the outer periphery face of the sheet roll of the brake pad. <P>COPYRIGHT: (C)2012,JPO&INPIT |
