Abstract: An apparatus is described for needling a non-woven material with a support (1) receiving at least one needleboard (3), which support is drivable in a reciprocating fashion both in the needle-penetration direction (5) as well as the direction of passage (6) of the non-woven material and on which are coupled the connecting rods (9, 10) of two oppositely drivable eccentric drives (7, 8) for the drive in the needle-penetration direction (5) and on which acts at least one additional eccentric drive (7, 8), and with a device for setting the movement component of the support in the direction of passage (6) of the non-woven material. In order to provide advantageous constructional conditions it is proposed that the connecting rods (9, 10) of the two oppositely drivable eccentric drives (7, 8) extend inclined in an opposite direction with respect to the needle-penetration direction (5), that the additional eccentric drive (7 or 8) revolves synchronously with one of the two other eccentric drives (7, 8), that the connecting rod (9 or 10) of the additional eccentric drive (7 or 8) which is also articulated on the support (1) forms a parallelogram of links with the connecting rod (9 or 10) of the synchronously revolving eccentric drive (7 or 8) for the purpose of guiding the support (1) and that the oppositely drivable eccentric drives (7, 8) are drivable through separate motors (18) which are adjustable with respect to their mutual rotational angle position through a control device (19).

Abstract: For the production of a nonwoven web from a primary nonwoven web a conventional carding drum is used as well as a collecting surface, on which a vacuum is applied and which is continuously moved and serves to collect the fibers flying from the carding drum. In order to ensure desirable conditions for the entrainment of the fibers flying off, the fibrous covering on the carding drum is sucked from consecutive layers on consecutive portions of the surface of the drum so as to from partial streams of fibers in suction passages between the carding drum and the collecting surface.

Abstract: In order to avoid the need for providing expensive fine rovings, a process is proposed in which two rovings are supplied to respective ring spinning stations (3). A common primary roving (2) is drawn and is subsequently divided into two separate rovings (2a, 2b) for feeding respective ring spinning stations (3). The primary roving (2) is divided into two separate rovings (2a and 2b) by conveying means (11), which comprise two juxtaposed suction zones (12a, 12b), which extend in the direction of conveyance.

Abstract: An apparatus for making a non-woven fabric comprises a plurality of tooth-carrying carding drums, which rotate in the same sense and succeed each other in the direction of travel of the preliminary web. Each carding drum which succeeds another in the direction of travel of the preliminary web constitutes a worker roller for the next preceding carding drum. The fibers flow off from the carding drums in discharge ducts and are deposited on a collecting surface, to which suction is applied. In order to ensure a uniform deposition of the fibers on the collecting surface, each discharge passage is provided adjacent to its boundary walls with an air inlet opening, which extends throughout the width of the collecting surface and is constituted by an air-entraining injector nozzle, which is directed toward the collecting surface and discharges an air stream which is parallel to the boundary wall.

Abstract: Juxtaposed, closely spaced, first and second drums are provided, one of which is approximately as large as the other. Said drums define between them a triangular space adapted to receive textile fibers approaching on one side of said drums in a freely flying state. Suction-exerting means are provided only in said first drum and operable to subject said fibers in said triangular space to suction. Said first drum has a suction zone adjoining said triangular space and communicating with said suction-exerting means. Said second drum has a structured outside peripheral surface. The first and second drums are operable to rotate in the same sense so that said first drum revolves away from said triangular space and said second drum revolves toward said triangular space on said one side of said drums so that said fibers received in said triangular space and subjected to suction therein through said suction zone are twisted together to form a yarn when said first and second drums are thus rotated. Said apparatus also comprises means for withdrawing said yarn toward one end of each of said first and second drums while holding said yarn against rotation.

Abstract: A unit for disintegrating a sliver into spinnable fibers fed to a spinning machine comprises a fiber-disintegrating drum with serrations generating a cylinder on rotation of the drum. A first smooth feed roller guides the sliver to the cylinder and defines therewith a first and second wedge-shaped space on the sides of which the serrations approach and depart from the first feed roller during a rotation, and this feed roller may be adjustably spaced from the cylinder. A second clamping and smoothing feed roller is disposed in the first wedge-shaped space and defines a nip with the first feed roller, the feed rollers being operable to feed the sliver through the nip to the serrations. A cover extends into the second wedge-shaped space and is closely spaced from the first feed roller and as closely as possible from the cylinder. A first pair of pinch rollers feed the sliver to the nip and a second pair of pinch rollers feed the sliver to the first pair of pinch rollers, the first pair of pinch rollers being driven at a higher speed than the second pair of pinch rollers, and the feed rollers being driven at a higher speed than the first pair of pinch rollers.
