Abstract
An adhesive dispenser for iteratively dispensing a controlled amount of an adhesive from a reservoir, by iteratively applying a pressure to the adhesive stored in the reservoir such that the controlled amount of adhesive is released from a nozzle connected to the reservoir via a supply passage and is applied to an object, the adhesive dispenser including at least one of an adhesive-temperature control device which controls a temperature of the adhesive present in the supply passage, by supplying a fluid to a first space at least partly surrounding at least a portion of the supply passage, and a pressure control device which is switchable to at least a pressing state thereof in which the pressure control device supplies a pressurized gas to a second space above the adhesive stored in the reservoir and a sucking state thereof in which the pressure control device sucks the gas from the second space.
