A pole for supporting a cable. The pole includes a plurality of truncated cones arranged in a linear array to form the pole, wherein each truncated cone receives an adjacent truncated cone within its interior. Each truncated cone in the pole is formed from a veneer by moving the longitudinal edges of the veneer towards each other. A method of manufacturing the pole and various uses of the pole are also provided.

Disclosed herein is a method for efficiently producing formaldehyde-free veneer manufactured boards, comprising steps of: using wood or non-wood veneer as a raw material; controlling the moisture content of the veneer to within an appropriate range; first applying an accelerant and then applying an isocyanate adhesive; then assembling the veneer into a slab according to a certain rule; carrying out microwave preheating on the slab; and feeding the slab into a hot pressing mechanism to obtain aldehyde-free veneer manufactured boards. In the present method, the process for producing aldehyde-free veneer manufactured boards is simple and easy to implement, hot-pressing production efficiency is high, and the mechanical properties of the boards are excellent.

A system for manufacturing a three-dimensionally deformed plate made of a wood fiber material comprises a preheating station, a wetting device, and a molding station including two rollers spaced apart for receipt of a preheated and wetted flat wood fiber material plate therebetween. The rollers respectively include an external surface including a wave-shaped profiling in the peripheral direction, wherein the respective profiling has half-waves which follow one another in the peripheral direction, and which have a different extension in the peripheral direction

A composite material and structure. The structure has a folded sheet having a rigid inner layer sandwiched between flexible outer layers. The sheet has an undulated shape with alternating summit and valley portions. Intermediate portions each extend between adjacent summit and valley portions. At least one score line extends through at least one of the flexible outer layers. The sheet is folded about the at least one score line. A method of forming a structure from a sheet having an undulated shape

A method of manufacturing crop straw fiber board includes the following steps: (1) mashing and choosing the straws with the length of 10-40 mm and the moisture content of 20%-30% as raw materials; (2) sending the raw materials into a digester (5) to digest and soften the straws; (3) sending the raw materials into a defiberator (7) and grinding to obtain straw fibers; (4) sending the straw fibers into a liquid applying system to mix with the adhesive, then drying with hot wind; (5) paving the straw fibers, then pre-pressing to obtain a plate blank with the thickness of 30-180 mm; (6) sending the plate blank into No. 1 hot press (8) to dehydrate; (7) sending the plate blank to No. 2 hot press (9) to adhere the plate blank; (8) sending the plate blank to No. 3 cold press (10) to shape the plate blank; (9) trimming and sanding the plate blank to obtain the fiberboard. Any crop straws could be used for the method.
