Finger Jointing of Plantation Timbers using indigenously developed Finger-Jointing and Finger Shaping Machine
 
 
With the increasing consciousness preservation of natural rain forests, large girth logs of exotic species like teak, rose-wood etc. are no more available in required quantities. The future has to be processing of plantation timbers like rubber wood and poplar wood. Plantation timbers are small girth logs and the trees are usually felled when still immature.
 
 
The juvenile timber leads to growth stresses which manifest themselves in the form of misbehaviour of timber even after drying. It is therefore necessary to end join smaller sections of plantation timbers to make them up to usable lengths.
 

Recognising the need for such a process, BMTPC has developed a complete line of finger jointing and shaping machine
. This new generation of wood processing machinery, finger-jointing machine (FJM) offer a financially viable approach to maximize wood recovery and using FJM it is possible to efficiently turn a large proportion of wood waste materials into valuable products. Finger jointing short length sawn timber, particularly from warp prone plantation species can facilitate production of higher quality solid wood products.
 
 
 
A study was conducted to evaluate the strength of Finger joined timbers from plantation grown species. It was found that finger jointed timbers from plantation grown species such as Eucalyptus, Silver oak and Rubber wood gave finger joint efficiency in the range of 60 - 73% of the original defect free wood of the species. In addition the finger jointed wood is found to have greater dimensional stability.
 
 
The license for commercial production of the indigenously developed finger jointing and shaping machine has already been issued and subsequently machine is also installed at Indian Plywood Industries Research and Training Institute (IPIRTI), Bangalore for demonstration and Research &Training.  In India, use of finger-jointing technique is now bound to increase exponentially which otherwise was severely restricted due to high cost of imported finger-jointing machines.
 
 
 
PROJECT OBJECTIVES
To indigenously design and develop a set of machines for finger jointing treated and seasoned plantation timber to obtain long and usable lengths. These machines are available at the lowest possible cost so that this technology can be propagated to even the smallest of processors of plantation timbers.
