摘要:
The invention relates to a method and an apparatus for controlling the quality in the manufacture of composite material which contains fiber based and polymer based material, wherein the manufacture includes a mixing process (1) to form agglomerates from a raw stock mixture. According to the invention, a combination of variables in the mixing process is observed, wherein the variables are selected from the group of moment, current consumption, time, sound, temperature and their combinations, and the mixing process as well as the quality of the agglomerates to be formed is controlled based on the acquired observations (6, 7).

The invention relates to an L-profile shaped element for covering an edge of a terrace structure. The L-profile shaped element includes a first (2) and a second (3) leg arranged to have substantially the same thicknesses. At least one edge of each leg is provided with joint parts (13), being selected from a groove or tongue structure, functioning in the substantially same manner regardless which way around the element has been turned. The L-profile shaped element (1) being arranged to be joined from the thicknesswise end (7) of at least one of the first leg (2) and the second leg (3) to at least one plank-like additional element of substantially the same thickness, which is adapted to be connected to said L-profile shaped element by means of the joint parts (13).

The invention relates to a process and apparatus for the homogenization of feed stock. According to the invention, solid stock material is mixed in at least two successive homogenization steps (1), wherein each homogenization step comprises at least two adjacent tanks (2), and the stock material is fed into adjacent tanks of a first homogenization step (IA), at least two stock flows are conducted out form each tank of each homogenization step, and at least one stock flow is conducted from each homogenization step into at least one tank (2) of the following homogenization step.
摘要:
A method for forming a wood composite product (P) by extrusion with a manufacturing apparatus. The temperature profile prevailing in the manufacturing apparatus is adjusted in such a way that the surface of the wood composite product to be formed becomes rough. Furthermore, the invention relates to a wood composite product and an apparatus for manufacturing a wood composite product.
