  • Cross-lapper
    Patent number: 9909236
    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).

  • Compensating device for fluctuating conveying speeds of a fibrous nonwoven
    Patent number: 9617104
    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).
