Abstract: The invention concerns a forming head for an apparatus for the production of a non-woven fabric by depositing fibers on a conveyor belt, comprising a fiber feeder which opens into a fiber processing chamber and which has a lower deposit opening for the delivery of fibers, wherein arranged in the fiber processing chamber are interengaging needle rollers with longitudinal axes oriented in mutually parallel relationship, which can rotate about their respective longitudinal axis, and the interengaging needle rollers enclose an inner chamber and are arranged with respect to the fiber feeder and the deposit opening in such a way that fibers fed to the forming head in operation enter the inner chamber by passing through between interengaging needle rollers and leave the inner chamber also by passing through between interengaging needle rollers.

Abstract: A former head allows processing of long fibers while achieving a carding action and a fibre distribution fulfilling high quality standards. The former head contains at least one needle roller. A mixture of air and fibers are injected above the horizontal plane of a center axis of the needle roller and directly onto a periphery of the needle roller. There may be a number of adjustable needle rollers. With a former head, where fibers and air are injected in a controlled and new way, it is possible to process longer fibers and maintain a high distribution quality. By using a number of adjustable needle rollers, the fibre material can go through a carding process during the distribution. This carding process is optimized by the needles injecting onto the periphery of the stationary needle roller as well as the subsequent contact with the adjustable needle rollers.

Abstract: An apparatus for uniformly distributing a disintegrated material on a fiber layer forming surface comprising a cylindrical housing having a perforated plane-surfaced bottom wall; an inlet opening for a stream of air containing suspended fibers and a stirrer having impellers rotating a short distance above the perforated bottom wall.

Abstract: A method and apparatus for distributing reinforcement fibers includes a chute for supplying reinforcement fibers, the chute having an outlet end, and a metering belt mounted for endless travel along a first path at the outlet end of the chute. The metering belt has elongate members with tips extending outwardly from the metering belt, to define a volume between the tips and the metering belt. The tips of the metering belt pass sufficiently close to the chute so that fibers having penetrated the volume formed by the elongate members are carried away by the metering belt. The metering belt is also mounted for endless travel along a second path around a curved surface which causes adjacent elongate members to spread apart and diverge from each other, thereby causing the fibers to be discharged from the metering belt. A collection surface receives the discharged fibers.

Abstract: A circular knitting machine for the production of knit goods with combed-in fibers, has a rotating needle cylinder in which needles having hooks for receiving fibers are mounted, at least one carding device having a feed apparatus for feeding a fiber strand, a separating apparatus for separating the fiber strand into a stream of individual fibers, and a combing-in zone through which the needles pass, and wherein the fibers are carried within the fiber stream for the purpose of contactlessly combing-in the fibers into the hooks of the needles. Guides are provided ahead of the combing-in zone for the purpose of dividing the fiber stream into partial fiber streams, thus considerably reducing or varying the percentage of fibers which are bound across several neighboring loops by several neighboring needles.

Abstract: The cleaning machine for fiber material has an opening roller provided with clothing. The cleaned fibers are again removed from the clothing into a suction chamber by means of a screening member containing a screening wall provided with a nose. The invention improves the clean separation or detachment of the fiber material from the clothing in comparison with the known arrangements, avoids collection of fibers at the nose of the screening member, and, in particular, requires a smaller quantity of suction air in the suction duct leading away from the suction chamber. To achieve this the mutual spacing of the screening wall and roller envelope or outer surface increases in a direction away from the nose in the direction of rotation of the opening roller towards the rearward end of the screening wall.

Abstract: An apparatus is disclosed for high speed production of uniform webs by air-laydown of textile fibers. A feed batt of staple fibers is fed to a toothed disperser roll that projects the fibers at high velocity and low angle into an airstream of high uniform velocity and low turbulence to form a thin fiber stream from which the fibers are subsequently separated on a moving screen in the form of a web. Air flow control means upstream of the toothed dispenser roll deflects the air stream at a constantly varying angle of deflection to improve fiber laydown uniformity.

Abstract: Circular knitting machine for the manufacture of knit wares of hosiery with combed-in fibers, having at least one needle bed possessing knitting needles and having at least one carding machine which possesses a feed apparatus for a band of fibers, a combing-in zone, through which the knitting needles pass, for the contact less insertions of fibers into the knitting needles, and a separating apparatus for separating the band of fibers into individual fibers. The separating device comprises a separating drum that can be driven at high peripheral speed and is provided with a fitting (card wires) for which a drive mechanism is provided that is independent of the knitting machine drive mechanism.

Abstract: A method and apparatus for forming non-woven webs by separating fibers from a compacted sheet or sheets of the fibers utilizing a lickerin. The method and apparatus include provision for attaining substantially individual fibers from a compressed sheet of short papermaking fibers such as wood pulp or cotton linters, and also fibers from a compacted sheet of longer fibers such as rayon, and blending the long and short fibers together into a non-woven web in the continuous operation of the lickerin and associated equipment. For the purpose of obtaining the short (1/4 inch and less) papermaking cellulosic fibers of wood pulp or the like the nose of the feed bar for the compacted short fibers is spaced a considerable distance from the working circumference of the lickerin such that the compacted sheet tip vibrates and the feed of the sheet of short fibers is substantially radially of the lickerin.

Abstract: An apparatus for increasing the width, or cross-machine-direction dimension of a fluid-entrained (e.g., air-entrained) stream of fibers to form a fibrous web that is wider than the stream of fibers. A rotatable spreading roll having a foraminous outer surface obliquely intercepts the open downstream end of a conveying duct through which the fluid-entrained stream of fibers is directed, and an intermediate web, wider than the stream of fiber in the first conveying duct, is deposited on this foraminous surface. The spreading roll is rotated to direct the intermediate web into communication with the upstream end of a second conveying duct, and a pressure differential established through the apparatus functions to relaunch the fibers of the intermediate web into the second conveying duct, and ultimately onto a foraminous forming surface to form a fibrous web product that is wider than the initially formed stream of fibers in the first conveying duct.

Abstract: An apparatus for increasing the width, or cross-machine-direction dimension of a fluid-entrained (e.g. air-entrained) stream of fibers prior to depositing the fibers on a foraminous forming surface to form a fibrous web structure. A rotatable spreading roll intercepts the open downstream end of a conveying duct through which the fluid-entrained stream of fibers is directed, and this roll includes a plurality of axially spaced disks providing flow-directing channels between them. The rotational axis of the spreading roll is oriented obliquely to the duct so that the lateral dimension of flow-directing channels between laterally spaced-apart duct sidewalls is greater than the width of the duct at its open downstream end, as measured generally normal to the direction of fiber flow through the duct.

Abstract: An apparatus for forming a fibrous structure includes a rotatable main drum having projections on its outer periphery for separating fibers from a fibrous feed, and directing the separated fibers through a fiber working section. The working section includes a movable satellite member positioned close to the main drum and having projections on its outer periphery for cooperating with the projections on the main drum to individualize the fibers as they are directed through the working section. A baffle is positioned adjacent the satellite member; between the satellite member and the exit from the working section. The baffle includes a lower air-directing section positioned close to the outer periphery of the main drum and having an air-diverting surface for intercepting air conveyed to it by the outer periphery of the main drum as the main drum is rotated.
