Abstract: The invention relates to an apparatus for producing nonwoven, fleece-like fiber products, said apparatus comprising a transfer belt configured to transport an intermediate product on the underside of a transfer belt to a roller arrangement, said roller arrangement comprising four rotatable rollers that are arranged and configured to interact in pairs in constellations that can be selectively modified, wherein each of the four rollers has a rotational axis, and the four rotational axes run at least approximately parallel to each other.

Abstract: A method for manufacturing a press fabric for a paper machine includes the attachment of a strip of top laminate layer material to a base fabric using a heat-activated adhesive film. The top laminate layer material may be a woven fabric, a nonwoven mesh, or a thermoplastic sheet material, and, in any case, has the heat-activated adhesive film bonded to one of its two sides. The strip of top laminate layer material and heat-activated adhesive film together form a multi-component strip, which is spiralled onto the outer surface of the base fabric, with the side of the strip of top laminate layer material having the heat-activated adhesive film against the outer surface, in a closed helix, and bonded thereto with heat and pressure. The portions of the multi-component strip overhanging the lateral edges of the base fabric are then trimmed, and a staple fiber batt is needled into and through the top laminate layer formed by the multi-component strip to firmly attach it to the base fabric.

Abstract: A method of compressing fibrous bodies which are held in place on a perforated support by means of negative pressure. Each fibrous body to be compressed is arranged on a first support that includes parts with and without perforations. A first compression of the fibrous body is then brought about over the part without perforations. The partly compressed fibrous body is then transferred to a second support which includes perforations in a part covered by compressed portions of the fibrous body and a part without perforations covered by uncompressed portions of the fibrous body. A second compression of the fibrous body is brought about in those portions of the fibrous body which cover the part without perforations of the second support.

Abstract: A press felt is devised for use in a papermaking machine, and a method is provided for manufacturing such a press felt. The press felt comprises a base fabric which is made of fabric of yarn material and is endless in the machine direction of the press felt, and one or more layers of fiber material arranged on the base fabric. The base fabric of the press felt comprises at least one layer composed of a spirally-wound strip made of fabric of yarn material and having a width which is smaller than the width of the final base fabric. Longitudinal threads of the spirally-wound fabric strip of yarn material make an angle with the machine direction of the press felt. The fabric strip of yarn material may advantageously be flat-woven.

Abstract: A gastight woven fabric sheet for air bags having no risk of burning a person due to formation of gas-permeable perforations and gas flowing out when the air bag is inflated, a high burst strength due to a reinforcing effect by adhesion, and a satisfactory feel, comprising a woven fabric composed of a plurality of warps and wefts each comprising a polyester multifilament having a yarn thickness of 200 to 550 deniers and a twist multiplier of 3,000 or less, and having a smooth surface formed by a calendering and a non-smoothed opposite surface thereof, the woven fabric having a gas-permeability function (ml/cm.sup.2 /sec) of 7.874 p to 78.74 p (wherein p is a pressure between 0 to 0.03 kg/cm.sup.

Abstract: A nonwoven fabric is produced by forming a batt of fibers which are oriented primarily transverse relative to the direction of movement of the batt, stretching said batt longitudinally relative to the direction of movement of the batt, and needling the stretched batt. Also apparatus suitable for the production of the novel fabric is disclosed.
