PCT No. PCT/SE92/00281 Sec. 371 Date Dec. 13, 1994 Sec. 102(e) Date Dec. 13, 1994 PCT Filed Apr. 29, 1992 PCT Pub. No. WO93/22134 PCT Pub. Date Nov. 11, 1994The release of a crepe paper web (1) from a Yankee-cylinder (4) is carried out with the aid of a doctor blade (5). The web is taken up on a roll (9) under a specific degree of creping. The paper web has a web-part which is drawn freely between the doctor blade and the roll, and with the aid of a device (11, 12) which functions to deliver a substance between the paper web and the Yankee-cylinder for controlling web release. A deformation force is exerted (via 20) on the paper web at a local part of the freely drawn web-part. The resultant positional change at that local web-part is detected so as to obtain an electric signal corresponding to the tension in the paper web. That signal is passed to a control unit (13) for controlling the supply of substance to control release of the paper web from the Yankee-cylinder. |
