- 6. The method of claim 5 wherein the folding back of said integral end portion of the tape is effected by bending it up and then squeezing together said portion and that part of the tape facing said portion by the pressing thereof against the oncoming leading end of the case being fed forward.
- 7. The method of claim 6 wherein the pressing is effected by a roller and the bending up of said integral end portion is effected by having said end reach of the tape extend over the roller and thence over a pocket one side of which is defined by the roller, and forcing the tape into said pocket.
- 8. The method of claim 7 wherein the tape is forced into the pocket by directing a blast of air on the tape to blow the tape into the pocket.
- 9. The method of claim 7 wherein the roller moves up said leading end of the case and then presses the tape down on said flaps at the top of the case as the case is fed forward, and wherein the pocket is defined by a pocket-forming member which moves with the roller and to a retracted position clear of the loop as the roller moves up.
- 10. The method of claim 9 wherein the tape is forced into the pocket by directing a last of air on the opposite face of the tape, which is its adhesive face, to blow the tape into the pocket and thereby form a loop of the tape at the end thereof in the pocket.
- 11. Apparatus for taping a case having a closure comprising two folded-over flaps having adjoining edges, said apparatus comprising means for feeding the case forward in a predetermined path with said adjoining edges extending in the direction of feed, means for guiding a continuous length of tape having adhesive on one face thereof from a supply thereof toward said path for pressing of the tape against the case to adhere it to said margins as the case is fed forward in said path, means for pressing the tape against the case, the tape being pulled from the supply by the case, means for severing the tape transversely to provide a length thereof for adhereing to said margins along said adjoining edges, and means for at least partially folding an integral end portion of the tape back on said face of the tape prior to the pressing of the tape against the case adjacent said integral end portion of the tape, said end portion being adhered to the tape to form a tab which is unadhered to the case for being grasped and pulled to peel the tape away from the case.
- 12. Apparatus as set forth in claim 11 wherein said folding means is operable to fold back the leading end of the tape.
- 13. Apparatus as set forth in claim 12 wherein said folding means is located in said path for engagement of the leading end of the case with said integral end portion of the tape.
- 14. Apparatus as set forth in claim 13 wherein said folding means is operable partially to fold back the leading end of the tape before engagement thereof by the leading end of the case an the folding is completed by engagement of the leading end of the case with the partially folded leading end of the tape.
- 15. Apparatus for taping a case having a closure comprising two folded-over flaps having adjoining edges, said apparatus comprising means for pressing a strip of tape having adhesive on one face thereof against the margins of said flaps along said adjoining edges to adhere the tape to said margins, and means operable prior to pressing the tape against said flaps for folding back an integral end portion of the tape on said face of the tape and adhering said end portion to the tape to form a tab which is unadhered to the case for being grasped and pulled to peel the tape away from the case, the case having a top constituting the said closure, a bottom, sides and ends, the flaps and their said adjoining edges extending endwise of the case, comprising means for feeding the case forward endwise toward an end reach of a continuous length of tape issued from a supply thereof, the tape being disposed with the adhesive face thereof in said end reach facing the leading end of the case and being generally centered with respect to said flaps, said integral end portions of the tape being constituted by an end portion of said end reach, said end portion, when folded back, leaving the adhesive on the adjacent part of said end reach, said pressing means comprising a first pressing means for pressing said reach of the tape including said folded-back portion and said adjacent part of said reach against the leading end of the case as the case moves forward, then pressing the tape down on top of the flaps, said apparatus including means for severing the tape to provide a length thereof sufficient to extend down on the trailing end of the case, and said pressing means further comprising a second pressing means for pressing the tape down on the trailing end of the case.
