[2] In Understanding Wood , Hoadley describes "rift grain" as occurring at an angle between 45–90° to the surface, and describes the AWI definition as "bastard sawn".
An important innovation by Scintilla-Bosch in 1966 [5] was the "pendulum action", where the blade tilts forward in the upward (cutting) stroke, and back for the down-stroke, ejecting the chips, so the blade runs cooler and cuts faster. A significant model was the Bosch "LESTO 8 554" in which the degree of "pendulum action" could be selected to ...

Cement particle boards are manufactured from 1 ⁄ 4 to 1 + 9 ⁄ 16 inches (6 to 40 mm) thickness making it suitable for high load bearing applications. These boards are made of a homogeneous mixture and hence are formed as single layer for any thickness. Cement fibre boards are more used in decorative applications and can be manufactured from ...
Wax prevents fibers from clumping together during storage. Chips in the case of particle board are also sprayed with a suitable adhesive before the next steps. Fibers or chips are arranged into a uniform "mat" on a conveyor belt. This mat is pre-compressed and then hot-pressed. Hot-pressing activates the adhesive and glues the fibers or chips ...
