  • Patent number: 9540745
    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.

  • Patent number: 8628456
    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.
