摘要:
A process for feeding fibres towards the fixed and mobile knives of a fibre cutter, such as a flock cutter, is provided which includes preparing a mattress of fibres aligned in a direction which is substantially perpendicular to the vertical plane of the knife so that the mattress of fibres takes the form of a band. The band is conveyed in a step-by-step manner towards the knives while supporting the band adjacent the fixed knife so that its lower face and its lateral side faces are supported by planer support surfaces having a dimension significant in relation to the length of sections of fibres being cut. The step-by-step conveying is effected by bringing the band to a temporary standstill in relation to the support surfaces as the fibres are advanced towards the cutter.

Conveyor, particularly a conveyor for materials in the shape of fibres lying in a sheet, said conveyor comprising at least two consecutive conveying elements at least one of which is movable and between which there remains a space; at least one movable member extending in said space cross-wise to the lengthwise axis of the conveyor; and moving means for imparting to said movable member a motion on either side of the median plane of said space between four end positions as follows: a first end position in which the member takes over the material falling in said space, a second end position in which said member lays the material having entered said space in such a position that said material will be taken over by the second conveyor element to pursue the conveying thereof on said conveyor, and two intermediate positions in which said member is situated in the proximity of the conveyor movable element and the second conveyor element; said means for moving said movable member being arranged so as said member and said conveyor movable element are driven in the same direction and so as said member defines a continuous curve in passing from one position to another.

There is described a method and apparatus for loading automatically, machines treating bulk materials in which from the bottom of a material mass is extracted, with projecting elements, an amount of material to form a strip. The strip is fed to the treating machines. The apparatus comprises arranging the projecting elements into at least two rows extending along the strip movement direction, and imparting to at least one element row, an alternating movement along the strip movement direction.
