    摘要: The invention relates to a card for the production of a nonwoven fabric web. The object is to provide a new card enabling a high production rate and the manufacturing to be interrupted without any breaks in the web itself. The card comprises e.g. three main rolls (12, 17, 20), whereby slower transfer rolls (15, 16; 18, 19) acting as working rolls as well are provided between said main rolls. At least one flatting roll (23) is provided after the last main roll (20), from which roll (23) the fibers are advantageously transferred onto a conveyor wire (29) by means of an aspiration roller (28), said wire passing the fiber material web to further treatment.

    摘要: The invention relates to an apparatus for the production of formed parts for use as pads in seats, for instance. The object is to provide a new apparatus with a different operating principle by means of which formed parts in which the density of the padding is uniform can be produced. The apparatus according to the invention comprises devices known per se for opening padding raw material into a desired looseness and for transporting it into a weighing device and for transferring the weighed batch of padding material into a filling chamber by means of a suction created by a vacuum pressure acting on the filling chamber. A porous mould through which the suction acts is positioned in the filling chamber for receiving the batch of padding material; that the padding raw material is at least partly formed of binding fibres melting under the influence of heat; and that the filling chamber is connected with means for introducing hot air through the mould and the batch of padding material contained in it for melting the binding fibre material of the batch of padding material at least partly, and thereafter for introducing cold air through the mould and the batch of padding material contained therein for solidifying the batch.

    摘要: A method and an apparatus for the moulding of a part from a gas-pervious raw material compound in a gas-pervious mould (14). The mould is positioned in flow chamber (10) in such a way that the gas flowing through the flow chamber is also caused to flow through the mould. A gas-pervious filling material chamber (16, 18) filled with filling material (26) is positioned in front of and/or behind the mould, which filling chamber brings about a desired, for instance an equally large, pressure drop over the "package" (12) formed by the mould and the filling material chamber along the whole cross-sectional area of the flow chamber. The invention also relates to the product produced by the method.

    摘要: The invention relates to a device for forming fibre balls out of elongated fibres carried in an air flow. The device contains a stator chamber (1) which is fixed to a frame and which has a circular cross section, and coaxially within it there is arranged a rotor (2), also having a circular cross section, and being rotatable around its shaft (3), whereby the rotor has on its periphery a plurality of radial blades (12, 12′) at mutual peripheral distances and at a short distance from the inner wall (1′) of the stator (1) in order to form an annular intermediate space (14) extending over the axial length of the rotor between the inner wall (1′) of the stator (1) and the blades (12, 12′) of the rotor (2). Further, means (8-10) are fastened to the frame and functionally connected to the shaft (3) of the rotor for rotating the rotor, and moreover, the device contains an input opening (5) at one end of the stator chamber (1) and an output opening (7) at the opposite end of the rotor chamber (1) in order to remove and to separate from the air flow the fibre balls formed in the intermediate space (14). According to the invention the stator chamber (1) and the rotor (2) are substantially conical, and they can be mutually positioned in the axial direction in order to adjust the width of said intermediate space without having to remove the rotor (2) from the stator chamber (1) in order to adjust the blades (12, 12′).
