Abstract: A fibrous-web-consolidating appliance which is configured to consolidate fibrous web and includes: at least two drive devices, each of which is configured to drive at least one needling device of the fibrous-web-consolidating appliance. Each needling device is configured to consolidate fibrous web and is driven by one of the at least two drive devices. At least one oscillation-recording device is configured to record oscillation data, the oscillations including oscillations such as those created by the operation of the needling devices. A control device is configured to receive the oscillation data recorded by the oscillation-recording device and to control the operation of the at least two drive devices in response to the received oscillation data. A control device and a method for operating the drive devices of the fibrous-web-consolidating appliance are also provided.

Abstract: A fluid processing system (2) for a fiber treatment system (1), which fluid processing system (2) has a moistening device (6), in particular a water-jet consolidating device, for a textile material web (3) and a preferably thermal drying device (7) for the moist material web (3). The moistening device (6) introduces process water (19) into the material web (3), which process water is removed from the material web (3) in the drying process. The fluid processing system (2) has fluid circuits (9, 10) and a regenerating device (16) for the process water (19) that is introduced into the material web (3) and thereafter removed and for the wastewater (32) arising in the process of moistening the material web (3).

Abstract: A cross-lapper (1) includes an upper carriage (2), a laying carriage (3), and two endless laying belts, which are each guided on the main carriages (2, 3) by deflecting rollers (15 to 21). The one laying belt (6) is designed as a feeding belt, which carries a fibrous web (9) and feeds the fibrous web to the upper carriage (2). The other laying belt (7) is designed as a counter belt. The upper carriage (2) has a belt deflection device (12) for both laying belts (6, 7). At the belt deflection device (12), the laying belt (6) is deflected by approximately 180 degrees from a feeding direction (11) thereof to the opposite direction by means of three of more deflection points (15, 16, 17).

Abstract: An automatic needle placement machine (1) and a placement method for needles (4) on needle boards (2) of non-woven needle machines has a holding apparatus (10) for the needle board (2), a needle removal apparatus (12) and a needle placement apparatus (13) for removing and placing needles (4) from and in receptacle openings (3) of the needle board. The holding, needle placement and needle removal apparatuses (10, 12, 13) can be moved and positioned in a linear manner and relative to each other by means of an automatic positioning apparatus (11, 16). The holding apparatus (10) for the needle board (2) has a multi-axis positioning apparatus (11), wherein the needle placement and needle removal apparatus (12, 13) are arranged in a relatively stationary manner on a frame (15) or on a machine frame (8).

Abstract: A compensating device (1) for fluctuating transport speeds of a fiber nonwoven (3). The compensating device (1) has a buffer belt (2) driven in a loop with three or four or more deflection points (12, 13, 14, 15, 16) and with a variable sag (11) of the carrying run supporting the fiber nonwoven (3). The compensating device (1) further has an adjusting element (19) for adjusting the location of at least one deflecting point (15, 16).
