In a method of dosing fibres, such as steel fibres to be mixed in concrete, a supply of fibres (5) is stored in first vibration feeder (2) and is moved from this by means of a second vibration feeder (3). For each dosing operation, a proportioned quantity of fibres (5) is transferred at a stepless rate or a stepwise declining rate from the first to the second vibration feeder (2, 3) while the second vibration feeder (3) stands still. This vibration feeder (3) then transports the transferred fibre quantity further on to the subsequent process while the first vibration feeder (2) stands still. The fibres can hereby be dosed more accurately and uniformly than known before. |
