20080196207 | CROSS LAPPER - A cross lapper for laying a fleece from a card web includes a laying carriage movable transversely with respect to an output conveyor belt and an upper carriage as well as a plurality of card web belts to guide the card web over the upper carriage and the laying carriage into a laying nip formed at the laying carriage, wherein a belt inlet is formed at the upper carriage over which a card web transport belt is guided, which from a lower end of an inlet path extends in the direction towards the laying carriage and is accompanied in parallel in this portion by an upper section of a first, endless cover belt guided through the laying carriage, said cover belt enclosing the card web together with same up to the laying carriage. The card web transport belt returned from the laying carriage to the upper carriage leaves the laying carriage above the upper section of a second endless cover belt passed through the laying carriage. This second cover belt forms a baffle surface within the laying carriage above the laying nip and in juxtaposition thereof, said baffle surface ensuring a safe guidance of the card web into the laying nip also case of higher card web transport speeds. | 08-21-2008 |

20100162543 | Needle Board for a Needle Machine - The needle board for a needling machine has a base plate with a plurality of receptacles, and a plurality of needle modules. Each needle module has a carrier plate which is equipped with a plurality of needles arranged in a predetermined pattern and which is inserted into one of the receptacles in the base plate in such a way that the needles project from the base plate. | 07-01-2010 |
20120180265 | Fleece Layer - The fleece layer for laying down a card web to form a fleece has a cross-lapping upper carriage, through which the card web is guided; a cross-lapping laying carriage, through which the card web coming from the upper carriage is guided and which serves to lay the card web down onto an output conveyor belt, and at least two card web conveyor belts for guiding the card web to the upper carriage and from there to the laying carriage. An upper run of a first endless card web conveyor belt extends from the infeed area of the fleece layer to the upper carriage and serves as a support surface for the card web. A positionally variable pressing means is provided, which can be actuated to produce a variable card web buffer in the upper run of the first card web conveyor belt. | 07-19-2012 |
20140033479 | Feed Device for Fibers or Fiber Flocks - The feed device for scattering individualized fibers or fiber flocks comprises a scattering section, in which a driven feed roller and a driven opening roller cooperating with the feed roller are arranged. A dispensing device for storing and dispensing a fiber sliver is assigned to the feed roller in such a way that the feed roller pulls in the fiber sliver provided by the dispensing device, as a result of which the feed roller is fed with the fiber sliver or the fiber fleece strip. The opening roller is arranged adjacent to the feed roller in such a way that it opens up the fiber sliver pulled in by the feed roller to form individual fibers or fiber flocks and scatters them. | 02-06-2014 |
20140033480 | Device and Method for Forming a Uniform or Profiled Fleece or a Uniform or Profiled Fiber Flock Mat - The device for producing a uniform or profiled fleece or a fiber flock mat includes a material dispensing device which produces a fleece and a transport device for the further transport of the fleece. The device also includes a measuring device to determine a transverse profile and a longitudinal profile of the fleece by measuring the mass per unit area of the fleece across its width, and a profile-changing device for supplying individualized fibers or fiber flocks to the fleece. A control unit controls the profile-changing device on the basis of the results of the measuring device in such a way that the profile-changing device supplies the individualized fibers or fiber flocks section by section in a targeted manner. Thus, depending on the purpose of the application, a uniform fleece or a fleece with a nonuniform transverse profile or longitudinal profile can be produced. | 02-06-2014 |
20140034399 | Feed Device for Supplying Individualized Fibers or Fiber Flocks to a Transport Device - The feed device for supplying individualized fibers or fiber flocks to a transport device, which serves to transport the formed fleece or fiber flock mat onward, includes a plurality of feed segments arranged horizontally next to each other and a plurality of individually actuatable feed rollers, wherein a separate feed roller is assigned to each feed segment. In addition, at least one driven opening cylinder, which cooperates with each feed roller, is also provided. | 02-06-2014 |
