Abstract
A bonded sheet material manufacturing system capable of setting a moisture content of various types of sheet members to be bonded to each other to an optimum value for stably producing a bonded sheet material with less bonding failure and less warp at all times, where the sheet members are heated by individual sheet member heating means and then bonded to each other to produce the bonded sheet material. The system comprises a moisture content detecting means provided for at least one of the sheet members for detecting a moisture content of the sheet member or a parameter correlating with the moisture content and a control unit for controlling the sheet member heating means on the basis of detection information from the moisture content detecting means so that the moisture content approaches a predetermined optimum moisture content.
