ABSTRACT:
Apparatus for the manufacture of a video disc caddy sleeve comprising folding platens, an intermediate spacer plate with indentations on the leading edge, and a selective heating means. Spacer plate causes plastic sheet to bend in the middle while folding platens close to a folded up position. Indentations on the leading edge act to keep label, already adhered to plastic sheet, from tearing while sheet is being bent into a U-shaped enclosure.
