Device for automatically peeling off the leading edge of a stencil from a stencil roll and master making device having the same

A device for making a master out of a stencil paid out from a stencil roll, comprising:

• a body;
• stencil storing means for storing the stencil such that the stencil can be paid out from the stencil roll,
• master making means for selectively perforating the stencil paid out from the stencil roll, thereby making the master;
• cutting means for cutting off the master from the stencil;
• a roll holding section movable into and out of said body and for holding the stencil roll;
• and
• automatic peeling means for automatically peeling off the leading edge of the stencil from the stencil roll while conveying the leading edge;
• said automatic peeling means comprising:
• peeling means for contacting or adjoining a circumference of the stencil roll in accordance with a varying diameter of the stencil roll, thereby peeling off the leading edge of the stencil;
• conveying means located in close proximity to said peeling means for contacting the circumference of the stencil roll in accordance with the varying diameter of the stencil roll, thereby conveying the leading edge of the stencil peeled off by said peeling means.
