Problems solved by technology

Higher dispersion chambers however lead to detrimental lateral turbulence resulting in an insufficiently uniform cross-machine profile of the particle mat due to uncontrollable fall of the particles on the conveyor along its cross-machine width

Embodiment Construction

[0032] Thus, in figure 1An apparatus for dispersing debris by means of spreading using an array of rollers 1 is shown in , while air flow enhances the grading of the debris. One such array of spreading rolls is disclosed in FI Patent No. 90746. Chips are fed in a conventional manner from a spreading chamber 2 onto an array of rollers 1 from which the chips fall onto a belt conveyor 4 forming a mat 3 of particles. The direction of travel of the belt conveyor is indicated by an arrow. A volume called the spreading space is located between the belt conveyor 4 and the roller array 1 . However, it is to be noted that the interspersed space discussed in the present invention may also be located eg between two roller arrays, or that no roller array is needed at all. An example of such a dispersion space is formed in an air jet dispersion chamber ( Figure 12 and Figure 13 ).

[0033] The device 5 according to the invention is adapted below the array of rollers in the spreading...

Abstract

An apparatus for scattering fibrous material, e.g., chips, said apparatus serving to spread chips using either a throw or air-jet spreading method to form a mat (3) of chips onto a moving band conveyor (4) or the like, whereby the scattering process avails a gas flow, such as air flow, for instance; the apparatus having a scattering chamber mounted above the band conveyor or the like. The invention is implemented such that, in order to prevent lateral turbulence, the volume of the scattering chamber's length wherein the major portion of the material being scattered falls onto the band conveyor or the like is at least partially divided into smaller subspaces adjacent to each other in the cross-machine direction by substantially thin plate-like elements (9) set apart from each other in cross-machine direction at a spacing substantially larger than the particle size of the material being scattered.

Description

technical field [0001] The present invention relates to apparatus for dispersing fibrous material such as crumbs by dispersing the crumbs by using throwing or air jet spreading methods to form a mat of crumbs on a moving belt conveyor or the like, whereby the dispersing process An air flow such as an air flow is suitable; the device has a spreading chamber mounted on a belt conveyor or the like. Background technique [0002] Dispersion of chips by means of rollers is basically known from patent publication FI-90746, which discloses a method for spreading fibers or chips together with binder onto a forming belt conveyor to form a mat, said apparatus comprising A roll array, the roll array includes at least three mutually parallel rolls, and the distance between the rolls is adjustable. The air flow is adapted to pass between the roller array and the belt conveyor by means of extraction or using a combination of blowing and extraction. [0003] From patent publication FI-200...
