A continuous paper sheet having a plurality of transversal perforation lines and a plurality of holes formed in the longitudinal margines of the paper sheet. The paper sheet is torn by means of two pairs of nipping rollers including a pair of the upper and the lower feed-in rollers and another pair of the upper and the lower pulling rollers. The pulling rollers of the latter pair rotate higher than that of the feed-in rollers of the former pair so that the part of the sheet placed between the former pair of rollers and the latter pair of rollers are pulled or given tension, being torn and separated. After the continuous paper sheet is confirmed that it is placed on a stand at the predetermined position, the width or distance of the continuous paper sheet folded is measured. The resultant of measurement is compared to the standard sizes previously inputted in a CPU in order to correct it to the approximate standard size. According to the corrected standard sire and the sheet thickness separately measured, the tearing-up operation of the pairs of the feed-in rollers and of the high speed or pulling rollers is controlled in order to give the continuous paper sheet a difference in transferring speed and to tear-up the sheet at the predetermined position of the sheet.
