Problems solved by technology

[0012] a) Spreading rollers arranged in the air flow are disadvantageous, since the air flow above them is thus hindered and uncontrollable turbulence occurs
Precisely at high stray material throughput, this leads to a poor density distribution over the length and width of the stray material mat and can result in detrimental overdensity

Embodiment Construction

[0039] In FIG. 1 there can be found a schematic structure of a spreading machine 1 with a pneumatic spreading box 13 . Depending on the design and embodiment of the plant for the production of composite wood panels, a stray silo (not shown) is located before or above the stray material charge. From this miscellaneous silo through the width of the forming belt 14, the miscellaneous material is input to the miscellaneous material feeding device 3 of the spreader in a controlled manner with a discharge roller (not shown), and a guide plate 2 is used to supply the wind power to spread the material. A roller screen 5 above the box 13. In this case, the roller screen 5 is formed by rollers arranged parallel to one another, the distance between which determines a gap size through which the foreign matter 4 can pass. The rollers can then be manufactured smooth or have a special surface pattern. Furthermore, a discharge device 11 for oversized foreign matter is assigned to the roller...

Abstract

The invention relates a method and a feed casting machine for producing stray material pads by whole or lamination way, wherein, the stray material pad is pressed by pressure and heat pressing. The task of the invention is to guarantee that overlarge stray material and / or slab rubber are selected via the length and the width of a forming belt in the situation of excellent quality of the spray material. The solution of the task of the feed casting machine lies that a roll screen (5) with a discharge device (11) for an overlarge spray material (4) is arranged above the airflow (10) of a wind feed casting box (13); a flying debris screen (7) is arranged in the airflow (10) of the wind feed casting box (13); a second screen (6) with a discharge device (12) for the overlarge spray material (4) is arranged below the airflow (10) and the lower edge of the flying debris screen (7) toward the second screen (6) is arranged as that the retained spray material (4) can fall on the second screen (6).

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for the monolithic or layered production of a mat of stray material made of debris and according to the preamble of claim 14 for the monolithic or layered production of a mat made of A spreader for mats of stray material consisting of debris. Background technique [0002] The manufacture of particle boards and eg medium density fiber material boards, during which automatic processes are applied and have been used in many countries for many years. As explained by Hansgert Soine' in "Composite Wood Products, Manufacture and Processing", DRW-Verlag 1995, p. 17ff., the compression of preprocessed wood chips or fibers takes place either periodically or continuously. At this time, in addition to the many equipment parts before and after the press, the stray material mat made by the spreader plays a prominent role. In addition to the quality of the raw material, the quality of the manufac...
