Definitions

  • the fibres are advantageously added during the dry mixing, which treats the largest amount of materials, and during which the material still has a comparatively loose and easily workable structure.
  • the short time available during this mixing and which lies within the range about 1/4 - 1 1/2 min, it is important that the plastic fibres get into contact with as much of the concrete mixture as possible immediately during the dosing proper if a satisfactorily uniform distribution of the fibres in the mixture is to be achieved.
  • the fibres When first the fibres have been worked into the mixture they can as a result of their lightness and relatively large surface only with difficulty be displaced relatively to the far heavier content of stone and sand in the mixture.
  • the fibre cut is supplied in comparatively large units in the form of bales or boxes, and it may thus be difficult to draw the fibres from the hopper sufficiently evenly and uniformly if the drum 11 is provided with pegs 14 over the entire width of the hopper. In particular it may cause problems to delimit the quantity which at a given moment is leaving the hopper, when the weighing mechanism 17a-d cuts off the motor 12, so that the metered quantity in the metering hopper 17a-d is not metered with the necessary accuracy.
  • the drum 21 is according to the embodiment shown in figs. 10 and 11 only partly provided with pegs 22 in its axial extension, whereby the pegs take out a comparatively smaller fibre cut portion for each rotation of the drum.
  • a displacement mechanism 23 shown symbolically in the figure as a crank throw, for displacing the drum 21 to and fro so that the fibre supply 15 is successively removed along the entire width of the hopper.
