    摘要： The invention relates to manufacturing low weight high quality paper suitable for use as a support layer of a release liner. A paper web is formed from pulp slurry, the moisture content of the paper web is reduced by a press section (PSEC), the paper web is supported by a belt (BELT1) from a first contact point (CP1) in the press section (PSEC) to a first separation point (SP1) in a drying section (DSEC), and the paper web is dried to form paper. The temperature profile of the paper web may be non-decreasing. When supported, the temperature of the paper web of the paper web may be higher than or equal to 56° C. to obtain a paper web having a dry content of at least 40 wt.-% at the first separation point.
