Problems solved by technology

However, such an intermediate layer increases the manufacturing cost and causes the problem of deformation of the final product over time or at room temperature changes due to different water contents
The disadvantage of density boards (English, particleboards) is their high weight, which increases the difficulty of handling

Embodiment Construction

[0170] figure 1 A paving head is shown comprising a smooth roller 5 as a conveyor roller with rotationally symmetrical sides and a planetary roller 6 as a conveyor roller with non-rotationally symmetrical sides, wherein a plurality of planetary pins 13 act as protrusions to Arranged on the side of the base column 12 in a manner parallel to the axis. The loosely assembled straw half-husks are fed by the material supply unit 1 onto licker-in rollers 7 as respective first transfer rollers of two roller rows 2 arranged mirror-symmetrically with respect to the intermediate plane 20 . The large number of radial rods 14 of the licker-in roller 7 , which are arranged at a high density on the side of the licker-in roller, enables the assembled straw half-shells to be separated as far as possible into individual straw half-shells. figure 2 The specific structure of the conveying rollers 5, 6, 7 of the roller row 2 is shown. The rotating smooth roller 5 and the adjacent, directly adjo...

Abstract

The invention relates to a method for producing a panel, a panel produced by the method, and a scattering head and an outer-layer scattering head for producing a panel on the basis of cereal crops. A scattering head with pairs of smooth rollers and planetary rollers directly adjacent one another allows both long and short stalk half shells to be scattered homogeneously onto a conveyor belt over the entire length of the scattering head. Paddle wheels provide a transverse orientation, in particular in the case of long stalk half shells. Panels with a high density, low variation in density in the longitudinal direction and a smooth surface can thus be produced. Through combination of the scattering head and the two outer-layer scattering heads, all the rotation shafts which are distributed in the two outer-layer scattering head in a pyramid shape rotate in the unified rotation shaft rotation direction. Different types of panels can be flexibly produced with low cost, and the panels have a plurality of different kinds of layers and length difference on cross sections.

Description

technical field [0001] The invention relates to a method for producing a slab, a slab and a paving head and an outer layer paving head for producing a straw plant-based slab. Background technique [0002] Mats based on straw plants such as straw or reeds (i.e. reed stalks) have the advantage of being able to use agricultural waste as compared to conventional MDF, oriented density board or MDF Advantages of materials instead of trees as raw materials. However, straw plants are much more difficult to handle than wood because of the long, thin culm-like structure. In order for straw plant-based slabs to be sustainable in the market relative to traditional wood-based slabs, manufacturing methods must be further developed to be able to produce slabs with properties that in some respects are more advantageous than wood-based slabs. slabs based on straw plants. Currently, in wood-based slabs, the problem also concerns e.g. a rough surface after manufacture, so usually wooden MDF...
