Abstract
Abstract This invention relates to a process and a device for the distribution of a conveyed flow, such as particles for the preparation of chipboard, fiberboard, or the like, by means of a separation of the conveyed flow into two partial flows. The distribution is continuous and uniform and provided, for example, by a distributing device which may have a variable insertion into the flow stream. The distributing device may have a separating plate with an active edge having regularly-spaced tongues and slots. A dividing plate having chutes of variable width extending through it can be used to vary the ratio of particles separated in the two directions. Baffled rollers may be used to ultimately guide the separated streams. The separation may also be accomplished by chambered rollers rotating in opposite directions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
174 words
An apparatus for the distribution of a conveyed flow of particles for the production of chipboard, fiberboard or the like by separation of the conveyed flow into two partial flows comprising a feeding device for continuously supplying the conveyed flow of particles, a discharge device disposed below the feeding device for continuously receiving the conveyed flow of particles and continuously discharging such particles, a generally planar rake-shaped distributing device disposed below the discharge device for continuously distributing the flow of conveyed particles received from the discharge device in two different directions, the rake-shaped distributing device comprising a plurality of spaced apart flat tongues with each adjacent pair of tongues separated by a slotted portion, the discharge device and rake-shaped distributing device being constructed and arranged to cause a portion of the conveyed flow of particles to penetrate only the slotted portions of the rake-shaped distributing device to thereby produce flow in one direction and to cause another portion of the conveyed flow of particles to flow along the flat tongues in a different direction.
Claim 2
Independent Claim
174 words
An apparatus for the distribution of a conveyed flow of particles for the production of chipboard, fiberboard or the like by separation of the conveyed flow into two partial flows comprising a feeding device for continuously supplying the conveyed flow of particles, a discharge device disposed below the feeding device for continuously receiving the conveyed flow of particles and continuously discharging such particles, a generally planar rake-shaped distributing device disposed below the discharge device for continuously distributing the flow of conveyed particles received from the discharge device in two different directions, the rake-shaped distributing device comprising a plurality of spaced apart flat tongues with each adjacent pair of tongues separated by a slotted portion, the discharge device and rake-shaped distributing device being constructed and arranged to cause a portion of the conveyed flow of particles to penetrate only the slotted portions of the rake-shaped distributing device to thereby produce flow in one direction and to cause another portion of the conveyed flow of particles to flow along the flat tongues in a different direction.
Claim 3
Dependent Claim
29 words
An apparatus as set forth in claim 1, wherein variable chutes are provided at the slots for adjusting the width of the streams passing through the rake-shaped distributing device.
Claim 4
Dependent Claim
21 words
An apparatus as set forth in claim 2, wherein the variable chutes are adjustable in their spacing relative to each other.
Claim 5
Independent Claim
34 words
An apparatus as set forth in any one of claims 1, 2 or 3, wherein a plurality of substantially parallel baffle rollers rotating in the same direction are connected below the rake-shaped distributing device.
