  • Patent number: 6212738
    Abstract: A method and apparatus for fibre production by recycling waste fibre material includes pressing the waste fibre material with a pressure element along a contact pressure line onto a surface of a feed roller. The pressure force of the pressure element is variable along the length of the contact pressure line depending on the thickness of the fibre material at a respective position on the contact pressure line so that a thick fibre material does not substantially influence processing of a thinner fibre material along the contact pressure line. The pressure element is radially adjustable relative to the feed roller and is configured with at least one adjusting end pressured device. The pressure element may also be adjustable along the circumference of the feed roller.
