Abstract: A feeding and rationing equipment for mechanical wood pulp, production waste and equivalent comprises a sheet tearing unit, a tearing unit for wood pulp, a distributor unit receiving the pre-flaked and mixed raw-materials from the tearing units. The distributor unit also comprises mixing and rationing devices. The material is transported through a number of cyclones to a feeding unit formed as a vertical pipe with a hinged door receiving blows in the outward direction from a flywheel and camshaft arrangement. The feeding unit feeds the raw-material to mills for further treatment.

Abstract: A method for the manufacture of disposable operation textiles. In the method at least on first layer of a non-woven fibre fabric material is fastened onto at least one second similar layer so that the principal fibre orientations of the layers become at least approximately perpendicular to each other. Said second layer is coated with a heat-sealable layer of synthetic material so that said layer in molten state and under tension is allowed to flow onto the web of fibre fabric. Then the combination is cooled whereby an internal prestress is produced and fixed in the coating of synthetic material. Said second layer is applied onto the first layer such that the layer of synthetic material comes against said first layer and the layers are fastened to each other by heat compression so that heat sealing occurs.

Abstract: A pre-tearing device for producing coarse flour out of bale plates of flake-dried wood pulp. The pre-tearing device comprises a feeding device for the plates and a rotating cylinder the surface of which is provided with spikes. The feeding device is arranged to feed the plates to be torn against the surface of the tearing cylinder in a direction that deviates from a direction perpendicular to the surface of the tearing cylinder. The spikes are arranged on the cylinder surface as two spirals rotating in opposite directions in relation to each other.
