| The most important stage is to purchase good quality logs in veneer manufacturing.Logs holded in the yard are kept green by sprinkling or immersion under water in log ponds. The two ends are usually covered with a wax emulsion to slow down evaporation of water from the log .So it is controlled log degrade which appears as a result of drying out and thus increase the getting of first quality veneer from the log. The logs are then cut into available lengths for peeling and slicing .The bark is removed from log and the surface is thoroughly cleaned to avoid knife damage and subsequent loss of production in the peeling and slicing operation. |

| Rotary veneer is processed on a 'veneer lathe'. In this machine the log is turned onto a knife nosebar assembly which is fed towards the centre of the log at a constant rate. The result is a continuous ribbon of veneer of uniform thickness. |

| Semi rotary veneer is produced on a rotary veneer lathe. |
| |
| Sliced veneer is processed on machine called a 'slicer' in which veneer are cut in a straight line action.There are two methods,either the flitch is held stable and the knife-nosebar moves back and forward over the flitch cutting one veneer each forward pass, or the knife-nosebar assembly is held stable and the log is passed backwards and forwards over the knife.The first of these methods is called horizontal and the second is called vertical. |

| After the peeling or slicing operation the veneer is mechanically dried in jet box type driers at temperatures up to 320 F degrees is blasted onto the surface of veneers at high velocities. The veneer must be dried to within defined limits usually 8 - 12% moisture content, to obtain satisfactory results in the subsequent gluing operation. |
| |
| |
| Once drying process goes end ,veneer is clipped to size. |
| |
| Finally the veneer is graded according to standards and (some is upgraded by repairing splits, patching knots etc.) before going into store. |
