    • PROBLEM TO BE SOLVED: To provide a blade die, adhesive manufacturing apparatus, a peeling method and a manufacturing method of the adhesive sheet capable of preventing generation of residual adhesion phenomenon when an unnecessary part of one of two sheets laminated through an adhesive agent layer is peeled off with the adhesive agent layer.SOLUTION: A blade die 21 forms a first notch with closed area shape at least to a frist sheet and an adhesive agent layer of a laminate R1 having the adhesive agent layer on one side face of the first sheet and obtained by laminating a second sheet through the adhesive agent layer and peels an outside region from the first notch of the first sheet together with the first sheet and the adhesive agent layer to make an inner region from the first notch the adhesive sheet, and has a base plate 210, a first incised blade 211 with the closed area shape supported by the base plate 210 and forming the first notch from the first sheet side of the laminate R1, and a second incised blade 212 supported by the base plate 210 at the outer region of the incised blade 211 and of which a plurality are arranged along a direction intersected with a peeling direction along which the outer region of the first sheet is peeled.
    • 要解决的问题:为了提供一种当通过粘合剂层层压的两片不需要的部分之间的片材时,能够防止产生残留粘附现象的粘合片的刮片,粘合剂制造装置,剥离方法和制造方法是 用粘合剂层剥离。解决方案:刀片模具21形成至少具有四边形片材的封闭区域形状的第一凹口和在第一片材的一个侧面上具有粘合剂层的层压体R1的粘合剂层 并且通过层叠第二片材并通过粘合剂层将第一片材的第一切口的外部区域与第一片材和粘合剂层一起剥离,以从第一切口形成粘合片的内部区域,并且具有 基板210,具有由基板210支撑的封闭区域形状的第一切割刀片211,并且从层叠体R1的第一片材​​侧形成第一切口 以及由切割刀片211的外部区域处的基板210支撑的第二切口刀片212,并且沿着与第一片材的外部区域剥离的剥离方向相交的方向配置多个刀片。
