Tree bucking is one of the initial stages of plywood production. Tree bucking is a process of cross-division of tree lengths into component parts: blocks, round logs, round wood, etc. It is carried out after tree felling and limbing. There are two types of bucking: single bucking and bundle bucking. Depending on the localization of raw materials, it can be carried out at cutting areas, loading platforms, woodworking enterprises, log storage places, etc.
Round log is the basic form of wood for further production of special sawmill products. It is divided into:
- shipbuilding timber (for the production of lumber used in the construction of barges and ships);
- sounding wood (for producing resonant goods);
- sleeper block (for laying the railway track);
- gun stock production block (for the manufacture of butts);
- ski production log (it is used as a basis for future skis);
- pencil production block (for the production of pencil boards);
- boot production block (for the production of shoe lasts).
For use as raw materials for veneer and plywood, the round logs are processed by planing and peeling.
The bucking process at the plywood plant consists of the following stages:
- logs on the conveyor belt are sent under a stationary circular saw;
- wood is sawn across;
- butt end is detached from the log;
- round log is measured in length and cut on the table;
- tree length is bucked into the specified sorts;
- received products are delivered to the conveyor.
The advantages of this method are obvious: easy maintenance and guaranteed reliability. In addition, the processed lumber is immediately sent to storage and transport distribution sites.
