Abstract

See full text

An adhesive agent applying apparatus has an ejecting section that ejects a thermoplastic adhesive agent and applies the thermoplastic adhesive agent onto one surface of a continuous sheet, traveling in a predetermined travel path and relevant to an absorbent article, by ejecting the thermoplastic adhesive agent from the ejecting section. The apparatus includes a contacting-detaching mechanism that causes relative movement between the continuous sheet and the ejecting section along a contacting-detaching direction, an ejecting mechanism that performs an ejecting operation of the thermoplastic adhesive agent from the ejecting section, and a controller that controls the contacting-detaching mechanism and the ejecting mechanism. The controller controls, when a travel speed of the continuous sheet is greater than a predetermined threshold value, the contacting-detaching mechanism and the ejecting mechanism in such a manner that, while causing the ejecting section to be in contact with the one surface of the continuous sheet, the thermoplastic adhesive agent is ejected from the ejecting section, and, when the travel speed is less than or equal to the threshold value, controls the contacting-detaching mechanism and the ejecting mechanism in such a manner that the ejection of the thermoplastic adhesive agent from the ejecting section is stopped and that the continuous sheet and the ejecting section come to a spaced apart state at the time the ejection is stopped or after the ejection has been stopped.
