ABSTRACT:
The method of winding paper onto a take-up roller of an automatic drafting machine, according to the present invention, involves the avoidance of winding the paper after each and every drafting operation. Rather, the method contemplates that, after each drafting operation, it will be determined whether the amount of paper, which has been driven forwardly after being utilized in a drafting operation and which has not yet been wound onto the take-up roller, is greater than a predetermined limiting value. If it is not, then no winding operation takes place. If, however, it is greater than the limiting value, a length of the paper equal to the length forwarded since the last winding operation is wound upon the take-up roller. After each such winding operation, the sequence of the method is repeated.
