For Gluing of wood, which method will be suitable for the purpose?
Right Answer is:
Gluing of wood
Dielectric heating is used for gluing of woods, In a number of wooden furniture items and other articles such as desk tops, table tops, corners of cots, drawing boards, etc. wooden panels are made by gluing boards together edgewise. Sometimes veneers (to cover with a thin layer of finer wood) are laid over glued panels. The main difficulty in the use of animal glue is of a long curing time and the parts to be joined have to be kept under mechanical pressure after application of the glue for a period of 24 hours in order to let the glue dry up.
Dielectric heating in the region of the glue between adjacent wood parts permits a strong bond with a stay-in-press time of only about 30 seconds. This dielectric heating may also be used for binding boards edgewise for making large panels. The glue used should be one that hardens quickly when heated to the desired temperature.
