Abstract: A method and a device for grinding strand-like fibrous material, wherein the strand-like fibrous material is fed towards the cutting edge of a cutting mechanism and wherein a moveable striking mechanism for grinding the fibrous material cooperates with the cutting mechanism. Associated with the cutting mechanism is a moveable clamping mechanism, by means of which the fibrous material is clamped in an oscillating manner. To produce optimally uniform fibrous shreds, as defined by the position of the cutting edge, the fibrous material is guided through an oscillating clamping gap formed between the clamping mechanism and the cutting mechanism, wherein the clamping mechanism is guided in a back and forth clamping movement relative to the cutting mechanism. For this purpose, the clamping gap is formed by arranging the clamping mechanism and the cutting mechanism opposite one another in a clamping plane.

Abstract: A device for dry-forming a fibrous web, in which a plurality of fibers or fiber mixtures is supplied to a forming head by means of an air flow, is described. The forming head includes a forming outlet arranged above a gas-permeable deposit belt. The fibers deposited on the deposit belt within a forming zone are continuously conveyed out of the forming zone by the deposit belt. A clearance of the forming zone formed between the forming head and the deposit belt is shielded with respect to the surroundings by several sealing means. To obtain as uniform a composition of the fiber layer as possible when depositing the fibers, the sealing means arranged on a feed side forms an inlet opening having an adjustable inflow cross-section through which a defined secondary air flow flows from the surroundings into the clearance.

Abstract: A method and a device for the dry forming of a fiber web, in which a multiplicity of fibers or fiber mixtures are fed to a forming head by means of an air flow is described. The forming head produces a fiber stream which is introduced into a clearance of a forming zone between the forming head and a laydown belt. To obtain as uniform a construction of the fiber layer as possible during the laying down of the fibers, the fibers of the fiber stream run through the clearance within the forming zone with free sections of different lengths. To this end, the forming head and the laydown belt are held in a non-parallel arrangement, with the result that the clearance is formed by different spacings between the laydown belt and the forming outlet of the forming head.

Abstract: A process for making an absorbent component comprises the steps of providing individual sheets of fibrous material, conveying the individual sheets of fibrous material to a cutting edge of a cutting mechanism, feeding the individual sheets of fibrous material through an oscillating clamping gap formed between a clamping mechanism and the cutting mechanism, grinding the individual sheets of fibrous material to form fibrous shreds, and laying the fibrous shreds on a forming belt to form the absorbent component.
