Abstract
PURPOSE: To aim at precisely adjusting an cutting end of a band-like material to a perforation applying position in the same phase by giving predetermined conditions to the diameter of a winding drum, the distance of an intermittent blade from a cutting line in a cutting and winding section and the timing of cutting.
CONSTITUTION: The diameter of a winding drum 6 is set to a value which is obtained in such a way that a diameter (d) relating to the edge of an intermittent blade 18 is multiplied by an integer N0 and is then divided by the number of the intermittent blades 18. Further, a cutting and winding section 9 associated with the drum 6 performs cutting operation at one and the same cutting position H with at the timing of every predetermined number of revolutions which is an integer N2 times as large as that of the drum 6. Meanwhile the phase of the intermittent blades 8 at a rotary blade 17 is set in such a way that the sum AH of the a rotational arc AB up to an edge contact line B to an under roll 16 and the span length BH cf a film S is equal to a value which is an integer times N1 large as pitches dπ/n at the time of cutting by the cutting and winding section 9. Thus, it is possible to simultaneous y and continuously perform both cutting and wind change-over by a constant length, and application of perforation, and then to wind up a winding core.
