Definitions
- shavings means chips, shavings or comparable particles produced by machining of any shape and size.
- the invention is based on the last-mentioned document, the technical problem of providing a method and an apparatus for producing a wood material body, whereby the strength properties are further improved.
- the fibers are directly after the comminution of the filamentary fiber material in particular individually in the Wood chips sprinkled or sprinkled on the wood chips. It is also conceivable to collect the fibers first and then to mix with the wood chips.
- These conveyor rollers are provided with cutting means, whereby the Verstärkungsfasem can be divided into sections of a certain length. If a plurality of conveyor roller pairs with different diameters for producing fiber sections of different lengths arranged side by side and these conveyor rollers can be positioned in any order to the inlet opening of the fiber conveyor channel, then the flow of flowable plastic in time sequence reinforcing fibers can be added in different lengths. This is particularly advantageous when the device for generating the two streams of flowable plastic and long reinforcing fibers is passed over the surface of a plastic molding tool to a flat, with long reinforcing fibers interspersed plastic part to create.
- the created with the above device annular flow channel can be created instead of a fixedly connected to the cleaning piston tubular approach with the help of a dip tube, which passes through the cleaning piston centrally and forms the fiber feed channel.
- a dip tube which passes through the cleaning piston centrally and forms the fiber feed channel.
- the cleaning piston can be moved independently of the dip tube.
- the dip tube may pass through the cleaning piston and its hydraulic actuators and be secured in the housing of the device. This results in the advantage that the means for generating long reinforcing fibers and for transporting these reinforcing fibers can be fixed to the housing through the fiber conveying channel in the dip tube.
