A dry film photoresist laminator includes a punch and die assembly 24 which punches a rolled sheet dry film photoresist material 14, that is comprised of a dry film photoresist material 18 sandwiched between a Mylar top layer 16 and a polyolefin bottom layer 20, into photoresist decals. The photoresist decals are bonded to a tacky transport tape 40 which carries the decals to a polyolefin peeler assembly 54 that rolls a high tack tape 57 along the polyolefin layer 20 of the decal, thereby peeling it from the decal. The decal is advanced by a laminating assembly 44 which rolls the decal onto a heated wafer 72, thereby bonding the exposed photoresist material 18 to the wafer 72. Bonded wafer 72 and decal 14 are removed from the transport tape 40. A tape transport assembly 44 carrying the transport tape and decal is advanced through the various process steps.

Photo resist film application mechanism

Apparatus for forming a disc envelope from a prepunched, flexible, plastic blank having two sections connected at the heads thereof and containing a drive hole at the same location in each section. The drive holes are located on respective hubs which are located at the same position on respective folding plates. The end edge of a mandrel is pressed against the blank in the area between the two sections while the folding plates are moved from a horizontal to a vertical position pulling the drive holes taut on the hubs and thereby locating the center fold between the two sections of the blank flap folding apparatus and sealing apparatus are attached to and swing into operating position with the respective folding plates to form the side flap folds and seal the folded flaps.

Centerfold forming apparatus for a disk envelope

The flexible disk envelope is formed from a flexible plastic prepunched blank having two connected sections. One section of the blank has side flaps extending from the opposite side edges. The blank is folded about an end of a mandrel so that the side flaps extend beyond the side edges of the mandrel. The mandrel holds the plastic blank section having the flaps extending therefrom against the bottom surface of a plate. The mandrel has raised edge portions running along the side edges on the outward facing surface thereof. The side flaps are folded around the adjacent edge of the mandrel in an outward folding direction by folding blades which are driven about pivot means to guide the folding blades in an arcuate path. Stops are provided which stop the arcuate motion of the folding blades and allow the upward motion means associated with the pivot means in response to the drive means to cause compression of respective flaps against the adjacent blank section and mandrel by said folding blades beyond said raised edge portions providing overfold zones Infra-red heating means are operable through windows in the folding blades adjacent the side folds to provide annealing of the fold thereby relieving any stresses therein.
