It is also referred to as 'Plain Sawn' or 'through and through'. veneer manufacturing board diagram. Rift sawn is the cut which falls between crown and true quarter sawn. It is straight grained and in oak, does not reveal any 'silver ribbon' grain features. Quality floor boards are prepared from rift sawn timber because it wears
Following the headrig, further breakdown of slabs, flitches and cants takes place in the resaw, which enables the wood to be upgraded; thick slabs being sawn into planks and the flitches and cants sawn into planks and boards. The rough round edges of the pieces coming from the headrig and resaws are removed by either
To provide an overview of the manufacture of dry-formed wood-based panels (particleboard, MDF, OSB), using particleboard as an example. • To introduce how the parts of the process affect the panel board properties. • To explain the hot-pressing process, particularly with regard to how the process affects
lumber. Pallet production can often be integrated with that of box, dimension, and other lumber products at the mill. Pallet producers can benefit from greater knowledge of the characteristics of wood and thefactors that are most important in pallets. In general, the quality of lumber usedinpallet manufacture may be character-.
Some other examples of wood products industries that would use process costing systems are paper, laminated veneer lumber, or pellet manufacturing firms. Figure 6 shows an example of a process costing system report card used by a railroad tie manufacturer. In this costing system, all cost elements are
Figure 86.1 Flow diagram for wood furniture manufacturing. Drying.

Manufactured or man made boards - are made from wood products and have new/different properties to the wood they were made from. Board sizes are 8ft x 4 ft (2440 x 1220 mm). The main types of manufactured boards are :- MDF (medium density fibreboard) made by a process which glues wood fibres together using
The more popular composites materials include plywood, blockboard, fiberboard, particleboard, and laminated veneer lumber. Most of these products are based on what were previously waste wood residues or little used or non-commercial species. Very littlematerial is lost in composites manufacture. Medium density

Engineered wood products (EWP) are made from lumber, veneers, strands of wood, or from other small wood elements that are bound together with structural
To counter this image, the laminated wood manufacturers met and finally settled on the term "plywood" to describe the new material. In 1928, the first of applications. Today, plywood has replaced cut lumber for many construction purposes, and plywood manufacturing has become a multi-billion dollar, worldwide industry.
