No answer description available for this question.

 Sunny Awasthi said: (Jan 5, 2016) What is gluing wooden sheet?

 Shailendra Kumar said: (Nov 30, 2016) Answer is D. Because they gluing at a pressure of 70 to 140 N/cm2.

 Jeetu said: (Jul 26, 2017) Option D is right.

 Roy said: (Jul 28, 2017) Glued sheets are loaded into a multiple-opening hot press. presses can handle 20-40 sheets at a time, with each sheet loaded in a separate slot. When all the sheets are loaded, the press squeezes them together under a pressure of about 110-200 psi (7.6-13.8 bar), while at the same time heating them to a temperature of about 230-315° F (109.9-157.2° C).

 Arya said: (Jun 19, 2018) D is the right answer.

 Ram Pravesh Chauhan said: (Jun 6, 2019) The answer should be Option D.

 Sumit said: (Aug 10, 2019) Plywood is obtained by gluing wooden sheets at a pressure of 100 to 150 N/cm^2. Plywood is formed through the bonding of three or more layers of wood using an adhesive.

 Dev said: (Sep 11, 2019) Plywood is obtained by gluing wooden sheets at a pressure of 100 to 150 N/cm2 and a temperature of 100 to 130 degrees Celsius. Plywood is made up of three or more thin layers of wood. These layers are bonded together with an adhesive.
