Abstract:
An apparatus for applying a viscous material, said apparatus comprising:an apparatus main-body having a storage chamber for storing therein a viscous material in communication with a discharge hole; a first viscous-material feeding device, placed at a first end of the storage chamber, for pressure-feeding the viscous material; a second viscous-material feeding device, placed at a second end of the storage chamber, for pressure-feeding the viscous material; an expandable discharge-pressure adjusting device which is placed in confrontation with an interior of the storage chamber or with the storage chamber, and which is to be expanded to adjust a discharge pressure when the viscous material stored in the storage chamber is pressurized and discharged; a moving device for moving the apparatus main-body on an application object, relative to each other, along a plane parallel to an application surface of the application object when the viscous material is discharged; and a flow-regulating member for, in a discharge of the viscous material, providing a stagnation point in a flow of the viscous material within the storage chamber generated during movement along the surface parallel to the application surface of the application object while the viscous material in the storage chamber is pressurized by the discharge-pressure adjusting device, wherein each of the viscous-material feeding devices feeds the viscous material continuously by replacement of a viscous-material feed cartridge, and wherein in order that the replacement of the viscous-material feed cartridge is carried out on a front side of an operator, the viscous-material feed cartridge, if positioned on a rear side of the operator, is moved along the plane parallel to the application surface of the application object so as to be placed on the front side, while a printing operation for one piece of the application object is performed, and thereafter halted on the front side of the operator.
