Viscous material feeding device, covering sheet used for viscous material feeding device, viscous material feeding method and mounting method of covering sheet

摘要

[Project] To provide a viscous material supply device for easy removal of viscous material that can be attached to a platen, a covering sheet used in the viscous material supply device, and a viscous material supply method. [Solution Means] The viscous material supply device 100 according to the present invention includes a tank 10 provided with a storage space 11 for storing the viscous material, and a pressing surface that is slidably inserted into the tank and presses the viscous material. (22) and a piston (20) provided with a suction passage (23) through which the viscous material in the tank flows by pressurization by the pressure surface, and the piston (20), which is in communication with the covering portion (31) covering the pressure surface on the piston, and the suction passage It has a covering sheet (30) with holes (32).
