Abstract
A method for producing uniform nonwoven webs from a supply of unordered fibre material includes discharging a quantity of fibre material onto a needle-type transport system having needles which are movable along a transport path, taking-up the fibre material by way of the needles on the needle-type transport system, transporting the fibre material in the needle-type transport system to an end of the transport system, discharging the fibre material onto an opening roller, separating the discharged fibre material on the opening roller and transferring the fibre material which has been separated on the opening roller onto a cylinder. An apparatus for producing uniform nonwoven webs includes a needle-type transport system for transporting fibre material along a transport path, an opening roller positioned along the transport path adjacent one end of the transport system and a rotatable cylinder positioned adjacent the opening roller for receiving the fibre material from the opening roller.
