Patent number: 11835906Abstract: In a foil transfer device for transferring a transfer layer from a foil film onto a sheet laid on the foil film, the foil film is wound on a supply reel, and taken up on a take-up reel. A heating member heats the foil film, and a pressure member is provided to press the foil film and the sheet between the pressure member and the heating member. A separator changes a traveling direction of the foil film having passed through between the heating member and the pressure member into a direction different from a direction of conveyance of the sheet, to thereby separate the foil film from the sheet. A first fan blows air toward the foil film positioned between the heating member and the separator.Type: GrantFiled: March 25, 2022Date of Patent: December 5, 2023Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventors: Kentaro Mori, Ryosuke Sakai, Ayaka Ohira, Tomoya Yamamoto, Seiji Hiramatsu
