PROBLEM TO BE SOLVED: To make the application state of an adhesive even when a coating line of the adhesive is formed on the surface of a continuously running web.SOLUTION: The nozzle 12 in a coater 11 for adhesives for forming at least one stripe of a coating line of an adhesive extended in the mechanical direction MD on the surface 2a of a web 2 continuously running to the mechanical direction MD has the following first to third work regions arranged in this order from upstream side to the downstream in the mechanical direction MD (1) a first region in which it is made possible to have contact with the web 2 in the entire width direction, (2) a second work region in which exits of the adhesive are formed between first divided parts arranged intermittently in the crossing direction rectangular to the mechanical direction MD, and (3) a third work region having second divided parts arranged intermittently in the crossing direction downstream of the first divided parts and step parts forming a step of at least 0.1 mm in a face on the opposite to the surface 2a of the web 2 between the second divided parts.COPYRIGHT: (C)2011,JPO&INPIT【課題】連続的に走行するウエブの表面に接着剤の塗布ラインを形成するときの接着剤の塗布状態を一様にする。【解決手段】機械方向MDへ連続的に走行するウエブ2の表面2aに機械方向MDへ延びる少なくとも一条の接着剤の塗布ラインを形成するための接着剤用コータ11におけるノズル12が、機械方向MDの上流から下流に向かって順に並ぶ下記の第1~第3作用区域を有する;(1)ウエブ2の幅方向の全体に接触可能な第1作用区域、(2)機械方向MDに直交する交差方向に間欠的に並ぶ第1区画部どうしの間に接着剤の出口が形成されている第2作用区域、(3)第1区画部の下流側にあって交差方向へ間欠的に並ぶ第2区画部と、第2区画部どうしの間にあってウエブ2の表面2aと対向する面が少なくとも0.1mmの段差を形成している段差部とを有する第3作用区域。【選択図】図1
