Abstract
A cutter plotter for drawing a roll type cutting sheet and cutting it, prevents bad influences accompanied with increasing of drawing resistance when drawing the roll type cutting sheet from a rolled part. If a feeding amount of the cutting sheet by a cutting order to be executed is over an amount already fed at that time, the cutting sheet is further fed in a Y-direction prior to execution of the cutting order for compensating said over amount.
Claims4
A cutting plotter using a roll type cutting sheet, comprising:
- feed means for drawing the roll type cutting sheet in a Y-direction while shifting the drawn cutting sheet back and forth along the Y-direction in response to a cutting order;
- cutting means for cutting the cutting sheet in a desired shape while shifting the drawn cutting sheet back and forth along a Y-direction;
- feed amount calculating means for calculating a maximum feed amount of the cutting sheet in the Y-direction of the cutting order to be executed;
- fed amount controlling means for storing as a fed amount a feeding of the cutting sheet in the Y-direction of the cutting sheet at a time of executing said cutting order;
- comparing means for comparing the maximum feed amount calculated by said feed amount calculating means with the fed amount stored by said fed amount controlling means;
- and
- compensation feeding means for, if the maximum feed amount of the cutting order is over the fed amount, further feeding the cutting sheet in the Y-direction by at least the excessive amount prior to execution of the cutting order.
