A method of continuously manufacturing liquid crystal display devices uses, in a bonding process, velocity control of the velocity (V2) at which a sheet piece of a pressure-sensitive adhesive (131) containing polarizing film (13) is bonded, and the velocity (V1) at which a carrier film (12) is taken up. When bonding a sheet piece to a liquid crystal panel (4) has started until the time when the sheet piece is completely peeled off from the carrier film (12) V1=V2, and after the sheet piece has been peeled off from the carrier film, but before the bonding of the sheet piece to the liquid crystal panel (4) is completed V1<； V2 to avoid that a next sheet piece is slightly curled on the front end of peeling means (40) to prevent the generation of air voids caused by adhesive lacking or adhesive deposits.本發明的顏面裝著具，是在框架的端部形成按壓面部，與按壓面部隔有間隔地設置一對支撐臂，在支撐臂的先端部之間，設置將緊固扣帶捲附的支軸，在支撐臂之間將操作構件可轉動自如地安裝，操作構件，是將內端作為按壓操作部，將外端作為拉起操作部，在按壓操作部，設有將框架的按壓面部按壓並使彈性變形的彈性片，在按壓操作部及拉起操作部的中間部，設有具有卡合爪的卡合體，將卡合體的卡合爪，在捲附於支軸並折返的緊固扣帶的表面側的長度方向複數設置的突出部的其中任一可卡脫自如。由此，在已裝著於顏面的狀態，容易操作操作構件，藉由按壓操作或拉起操作的其中任一，就可以將緊固扣帶鬆緩，成為非常地便利。且，將緊固扣帶鬆緩用的構成構件因為只有一個操作構件，所以組裝成為簡單。
