Abstract: A device for transferring nonwoven material from a fleece-laying machine to a consolidation device having an endless circulating output conveyor belt of the fleece-laying machine for accepting card webs which are laid on the output conveyor belt from above by the fleece-laying machine, the laid card webs forming the nonwoven material. A first drive unit drives the output conveyor belt at variable speed. In addition, a second drive unit for driving the output conveyor belt at an essentially constant speed is provided at a point which, relative to the first drive unit, is closer to the consolidation device. A hanging storage buffer of the output conveyor belt is thus formed in a section of the output conveyor belt located between the first drive unit and the second drive unit.

Abstract: In the production of a solidified nonwoven web by crosslaying a card web produced with a uniform transverse profile by a card web forming device and then by consolidating the crosslaid nonwoven web thus formed, the basis weight of the solidified nonwoven web or of the crosslaid nonwoven web is measured only in the middle and in the area of at least one of its edges, and the basis weight of the card web to be laid is locally changed on the basis of a comparison of the measurement values with the nominal values preestablished by the laws, previously described for the nonwoven web to be produced, governing the structural change in the product caused by solidifying.

Abstract: A hollow roll which includes a roll body closed off at each end by a plug-like end piece inserted with a precise fit into the roll body is provided. Each end piece includes an attached axially projecting journal to provide rotatable support for the hollow roll and each end piece has at least one meandering-like or substantially spiral groove in the part of its circumference which is seated in the roll body. The groove is closed off from the cavity of the roll and comprises a connection to the outside at each of the two ends of the groove which is completely filled with an adhesive.

Abstract: In a camel-back fleece laying machine with a laying arm attached to a joint, two endless card web transport belts are guided along this arm, and the bottom end of the laying arm carries a discharge gap, which is moved by an upper carriage transversely to the transport direction of an output conveyor belt in a plane above the output conveyor belt. A laying carriage is guided at a certain height between the output conveyor belt and the upper carriage on a path extending parallel to the upper carriage, and two closely adjacent deflecting rolls are mounted in the upper carriage, over each of which a cover belt is guided. The cover belts form a laying gap at the deflecting rolls, through which gap a card web supplied by the card web transport belts is conducted. The drive of the laying carriage is independent of the drive of the upper carriage, and the path of movement of the upper carriage extends beyond the path of movement of the laying carriage at least at one end.

Abstract: A device for compacting fiber flocks into a flock mat has means for supplying the fiber flocks, a discharge belt for carrying the compacted flock mat away, and walls, which are arranged opposite each other between the means for supplying the fiber flocks and the discharge belt and thus form the boundaries of an essentially vertical chute feed, which defines the transport direction of the fiber flocks. At least one of the walls is supported in such a way that its movement during each cycle has a component in the transport direction of the fiber flocks and a component in the direction transverse to the transport direction.
