An apparatus for pre-processing logs to separate outer jacket fibers, comprising a plurality of spaced apart rollers through which a log can pass, each roller having at least one outwardly extending concentric projection, the projection being suitable to separate fibers. A pressure mechanism determines the diameter of the log so that the rollers can provide the appropriate amount of pressure to and engagement of the projections with the log. A feeding mechanism moves the log along a flow path past the rollers.

A manufacturing apparatus for delaminating a bamboo into fiber and a method thereof are disclosed. The manufacturing apparatus includes a machine frame, a machine seat, a machine cover matched with the machine seat, a machine cover rail, a push plate, a push rail, at least one power source for sliding the push plate, and at least one elastic member. The manufacturing apparatus has a relatively simple structure and is easy for operation, use, and promotion. The manufacturing method using the manufacturing apparatus is simple in production process, high in efficiency, and free from pollution. The obtained bamboo fiber has good elasticity, good toughness, fine fiber fineness and uniformity, that is, the present invention can quickly and efficiently produce high-quality bamboo fiber, greatly saving the production time of bamboo fiber, improving the production efficiency, and reducing the production cost.

A safety device for a waste processing system having a powered cutting system including a rotor rotatably mounted within a housing is disclosed wherein the improvement relates to a safety device which includes a first safety device disposed within the housing, spaced from the rotor and thereby defining a first gap therebetween through which a cable that has been captured by the rotor assembly is automatically cleaved when disposed between the first safety device and rotor assembly.

A material reduction machine includes an infeed portion operable to receive material to be reduced, and a cutting mechanism operable to reduce material fed in from the infeed portion. An outlet chute has a first end operable to receive the material reduced by the cutting mechanism and a second end operable to discharge the reduced material from the machine, wherein the outlet chute extends along a curved path. The outlet chute includes, along a radially-inner side of the curved path, a foraminous interior wall providing communication with a sound attenuation layer.

A method of manufacturing engineered wood is provided, the method including: feeding wood through a processor while exposing the wood to compressive and tensile forces to produce naturally oriented strands of fibers; adding an adhesive to naturally oriented strands of fibers to provide adhesive covered strands; feeding the adhesive covered strands into a press; applying a first pressure to the adhesive covered strands to provide a pressed wood with a selected first dimension and a selected second dimension; and applying a second pressure normal to the first pressure to the pressed wood to provide an engineered wood having the selected first dimension, the selected second dimension and a selected third dimension and a selected density. An installation for manufacturing the engineered wood is also provided.
