Attachment method for disc protective sheet

Abstract

An attachment apparatus and method for attaching a disc protective sheet to at least one half of a magnetic disc cartridge body include a supporting mechanism that supports each half body section of the cartridge body. The apparatus and method also include a supply mechanism that provides disc protective sheets to the one half body section. Each protective sheet is punched from a web of material and includes a cutout that corresponds to an opening provided in the one half body section to expose part of a magnetic disc held within the body when assembled. Each protective sheet also includes a thermal fusible layer on an attachment surface opposite a surface that will face a disc when the cartridge body is assembled. Each protective sheet to be assembled is arranged so that the cutout and the opening in the one half body section corresponds to one another. A fusing mechanism has a shape that is slightly larger than that of the protective sheets and is positioned directly over the supporting mechanism. A one half body section including a sheet to be fused is positioned therebetween. The fusing mechanism presses the protective sheet and fuses the fusible layer to the one half body section to fixedly fuse the sheet to the body section. The supporting mechanism and fusing mechanism are moved toward one another to sandwich the one half body section and the protective sheet to be fused therebetween.
