- 8. The apparatus for bonding a pocket blank to a garment portion of claim 1, wherein said adhesive supply means comprises a plurality of adhesive supply spools each bearing a roll of heat fusing adhesive in strip form disposed upon a release backing and a plurality of corresponding paired release backing take-up spools for disposing a strip of adhesive above each of the member tabs of the pocket blank to be pressed downwardly for engagement with and for fusing to the respective member tabs.
- 9. The apparatus for bonding a pocket blank to a garment portion of claim 1, wherein said first heat and pressure means comprises a heated platen.
- 10. The apparatus for bonding a pocket blank to a garment portion of claim 9, wherein said heated platen includes an independently downwardly disposable center portion for holding down said pocket body of the pocket blank during the upward return motion of the platen after application of the adhesive strips, whereby freedom from sticking of the adhesive bearing member tabs to the platen is enhanced.
- 11. The apparatus for bonding a pocket blank to a garment portion of claim 1, wherein said first heat and pressure means is adapted to apply the adhesive strips to substantially the entirety of the length of the member tabs from the leading edge to the trailing edge thereof.
- 12. The apparatus for bonding a pocket blank to a garment portion of claim 11, wherein the heated platen is of such a temperature as to soften the adhesive sufficiently so as to cause application of the adhesive to the cloth confined to areas of contact with the platen and to cause terminal breakage of the supplied adhesive strip outside the trailing edge of the respective member tab.
- 13. The apparatus for bonding a pocket blank to a garment portion of claim 11, wherein said adhesive supply means includes control means for unrolling the heat fusing adhesive strips for disposition of the point of terminal breakage of the adhesive strip substantially directly above the leading edge of the respective member tabs.
- 14. The apparatus for bonding a pocket blank to a garment portion of claim 11, wherein said means for supplying the garment portions include a continuous garment cloth supply means disposed to supply the same in a path of travel transverse to that of the longitudinal dimension of the conveyor path of travel.
- 15. The apparatus for bonding a pocket blank to a garment portion of claim 14, further comprising a garment cloth cutting die for cutting individual garment portions at the third station.

- 17. The apparatus for bonding a pocket blank to a garment portion of claim 1, wherein said second heat and pressure means comprises a heated platen disposed above the plane of the conveyor for intermittent downward motion corresponding to the presence of a prepared pocket blank therebeneath for fusing.
- 18. An apparatus for bonding a pocket blank to a garment portion, said apparatus comprising:
- a conveyor including means for the intermittent controlled movement of the same, said conveyor having a longitudinal dimension along a defined path of travel;
- a continuous supply of pocket blank cloth disposed transversely across one end of said conveyor at a first station;
