The front shearing roller must have a temperature of 25.degree. to 90.degree. C. on the application side and of 30.degree. to 80.degree. C. on the removal side, the rear shearing roller must have a temperature of 30.degree. to 130.degree. C. on the application side and on the removal side of 35.degree. to 100.degree. C., and the temperature of the rear shearing roller must be at least 5.degree. C. above the temperature of the front shearing roller. In addition, the front shearing roller must exhibit a speed of 5 to 25 rpms and the rear roller a speed which is 5 to 70% lower.
