The invention resides in a method of forming a nonwoven web by employing a forming apparatus which includes a fiberizing roll for separating fibers from a feed mat and entraining them in a gaseous medium, a foraminous forming surface through which the gaseous medium passes and upon which the fibers are condensed to form a fibrous web, and a formation duct between the fiberizing roll and the forming surface for defining a flow path for the gaseous suspension of fibers from the fiberizing roll to the forming surface; the improvement wherein the formation duct includes front and back, substantially planar inner surfaces which may slightly converge in a direction from the fiberizing roll to the forming surface, but preferably diverge at an angle of up to about 41/2 degrees when the forming surface is a curved surface of a cylindrical drum, and up to about 11/2 degrees when the forming surface is a linear surface of a forming belt; the formation duct being inclined to the forming surface to define an incidence angle with the forming surface in the range of from about 10 DEG to about 30 DEG . The invention also resides in a method of forming a nonwoven web by employing the above-described apparatus. |

An apparatus and method for manufacturing a multi-layer web product. A long fiber stream is directed around a rotating carding cylinder. Two combing cylinders are disposed adjacent the carding cylinder to comb a first web of long fiber and a second web of long fiber, respectively, from the carding cylinder. A first conveyor receives the first web from the first combing cylinder and transports the first web toward a layering point. Similarly, a second conveyor receives the second web from the second combing cylinder and transports the second web toward the layering point. A short fiber deposition unit is disposed adjacent the second conveyor and deposits short fibers onto the second web. At the layering point, the first conveyor deposits the first web onto the second web, with the short fibers sandwiched therebetween, to form a layered web product. |

The spunlace device includes a second spunlace machine having a shaping layer on the surface, the shaping layer is provided with pointed projections having tapered tops disposed in a matrix arrangement, each pointed projection has a bottom of rectangular cross-section, the bottom size of each pointed projection is larger than the bottom distance between two adjacent pointed projections. A non-woven cloth having rectangular holes in an array layout is formed by water jetting the fiber-web at the second spunlace machine. The rectangular holes in an array layout are presented in a flat structure having warp and weft, and the dimension of each rectangular hole is larger than the line width of warp and weft. The features of such non-woven cloth are similar to those of gauze, so the non-woven cloth can be a substitute for the current gauze. |

The present invention relates to a method for the continuous production of laid staple fiber fabrics with aligned fiber orientation, in which method the laid fabrics are produced by continuous plaiting down of carded fiber web at defined laying angles onto a synchronized transport belt (1), wherein the carding machine (2) and plaiting means (3) arranged downstream of it are arranged at an acute angle with respect to the advancing direction of the transport belt. Said laid staple fiber fabrics are used for producing high-strength fiber-reinforced plastic composites, as are used in wind power plants, aircraft construction and the automotive industry. In particular in the loading direction, said composites have high composite strengths and rigidities, to which end a defined fiber orientation is required. In addition to a defined orientation of the finite fibers, the laid fabrics also have a defined mass per unit area. |

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. A cover belt is arranged to enclose the card web lying on the upper run of a first card web conveyor belt from above. The cover belt is smooth and is not moved when the card web is moved, thus serving as a stationary cover of the card web. |
