Abstract: An air laying device for producing a fibrous mat at least partially from a plurality of fibers including at least one of a plurality of wood pulp fibers and a plurality of cellulose fibers, the air laying device including: a ring distributor including a fiber feed and a ring channel, the ring channel including an outlet element forming a section of the ring channel; and a calming channel extending in a downward direction toward a forming fabric, the section being arranged within the calming channel, the outlet element including a plurality of openings configured for being that through which the plurality of fibers supplied by the fiber feed exit from the ring channel into the calming channel and move to the forming fabric to form the fibrous mat on the forming fabric.

Abstract: A connecting unit for connecting a drive device to a rod includes: a receiving opening for axially receiving a connecting element arranged on the rod to transmit a torque; an interlocking element including a free end and further including or being configured as a spring element, which is a flexible spring; and a recess located radially adjacent to the receiving opening and by way of which the interlocking element engages in the receiving opening, with the result that the connecting element is axially securable thereby, the interlocking element at a first position being firmly connected with a portion of the connecting unit and at the free end is configured for moving relative to a portion of the connecting unit so as to move the interlocking element out of the receiving opening, with the result that a securement of the connecting element is releasable.

Abstract: A method for producing a web of fibrous material includes the steps of: (a) low-water processing of cellulose-containing fibers into individual fibers and/or fiber bundles; (b) forming of the individual fibers and/or the fiber bundles in an air stream into a planar laid fibrous structure using a dry forming method; (c) moistening the individual fibers and/or the fiber bundles by way of a fluid; (d) solidifying the planar laid fibrous structure by applying pressure in a press nip; and (e) heating the individual fibers and/or the fiber bundles upstream from the step of solidifying (d) so as to increase a temperature of the individual fibers and/or the fiber bundles in the step of solidifying (d).
