Abstract
A former with a sieve, preferably with a cylinder mold, is provided with an adjustable discharge aperture for a fibrous material suspension exiting from a chamber that is formed between the sieve and an upper lip formed by a flow guide plate. The upper lip has a first end facing away from the chamber and is guided in a floating manner by a pressure medium in a direction toward the sieve, as well as in the opposite direction. The upper lip is supported in a floating manner also by a pressure medium at its second end facing toward the chamber. In this way, deflections of the upper lip in the region of the inlet aperture can be largely avoided.
