Abstract: The present invention relates to a flow rate control element for ducts, said control element operating based on the iris-diaphragm principle and including an annular housing comprised of a base part (3) with a cover part (4) made to fit thereon, and said housing having therein adapted essentially curved leaves (7), which are pivotally connected at their one ends to said housing, and further including a control ring having radial slots made thereto in which slots the other ends of the leaves are adapted to move, whereby said leaves are made steplessly rotatable between their closed and open positions by turning the control ring. The invention is implemented by forming for each leaf (7) to be installed in one part of the housing, advantageously the base part (3), a nonpenetrating indent or outdent, respectively, whereby to that side of the leaf to be installed facing said indented or outdented side is formed an essentially complementarily shaped outdent or indent, whereby the pivotal cooperation of the outdent/indent pair permits unobstructed rotation of the leaf (7) about its pivot point.

Abstract: The invention concerns a method for producing a paper web. According to the method a stock is produced from the fibrous raw material and the stock is formed to a web which is dried on a paper machine. According to the invention the stock is formed from a mechanical pulp prepared from wood material of the Populus family and from bleached chemical spruce pulp, whereby the amount of the mechanical pulp is 20 to 70 weight-% and the amount of the bleached chemical softwood pulp is 80 to 30 weight-% of the dry matter of the stock. It is preferred to use an aspen pulp, over 70 % of the fiber fractions of which comprise fiber fractions +100, +200 and -200, and the proportion of the -200 fraction is 45 % or less. A coated fine paper can be produced from the paper web whose properties are better than those of a traditional fine paper having the corresponding bulk and grammage, on the same opacity level the paper produced by the invention will give a yield gain of up to more than 20 %.
