PAPER THREADER Filed Feb. 1, 1953 MNT R M ATTORNEY Patented Feb. 26, 1935 PAPER THREADER Thormod Jensen, Laurelton, N. Y., assignor to American Machine & Foundry Company, a corporation of New Jersey Application February 1, 1933, Serial No. 654,734
4 Claims.
This invention relates to a novel paper threading device for wrapping machines, with the object of quickly and conveniently installing a new wrapper web. With this and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations hereinafter fully described and then specifically set forth in the claims hereunto appended.
In the accompanying drawing which forms a part of this specification and in which like characters of reference indicate the same or like parts,
Fig. 1 is a partial side view of a wrapping machine equipped with the paper threading device;
Fig. 2 is an enlarged detail view of the means for coiling the flexible tape; and
Fig. 3 is a detail plan view taken on line 3-3 of Fig. 1, showing the end of the wrapper looped around the feeding head of the flexible tape.
In carrying the invention into effect there is provided a stationary plate, a support for a reel of wrapping material, means for guiding the wrapping material from said reel to a position in front of said plate, and a paper threading device for pushing the wrapping material along said plate. In the best constructions contemplated the paper threading device includes a coiled semirigid metal tape provided with a feeding head on its leading end, and manually operable means for uncoiling and advancing said tape to cause said head to engage and push the wrapping material. These various means and 'parts may be'widely varied in construction within the scope of the claims for the particular device selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the specific construction shown and described.
Referring to the drawing, the side frames 10 of the wrapping machine support brackets 11 which carry cross shafts 12, 13 and 14. The frames 10 also support a tie-frame 15 to which is fastened a bracket 16 carrying a housing 17. In the housing 17 is rotatably mounted a stud 18 on which is fixed a core 19 carrying a coiled semi-rigid metal tape 20. The stud 18 carries a handle 21 thereby providing means to turn the core 19 thus unwinding or winding the semi-rigid tape. The
The wrapping material from reel W on cross shaft 12 is first manually threaded around the rollers 25, 26, 27 and 28 to bring its leading end in front of the plate 29. The handle 21 is then turned in a clockwise direction and the tape 20 is unwound, until the feeding head 24 encounters the wrapping material. The end W of the wrapping web is then creased and folded back over the feeding head, and the continued turning of the handle 21 unwinds the tape from the core 19 and advances it along the inclined plate 29. Thus the end W of the Wrapping web is advanced to its dotted position W" at the top of the inclined plate. The end W is then manually grasped and led over a roller 30, and a sufficient length of wrapping material is unwound from the supply reel W, thereby allowing the end W of the web to hang fro-m the roller 30, to a position in front of a package, which is pushed into the web to be enveloped therein, by means not shown.
The tape 20 is then returned to its former position by turning the handle 21 in an anti-clockwise direction, thus bringing the same out of engagement with the web W.
What is claimed is:
1. The combination with a stationary plate, of a support for a reel of wrapping material, means for guiding the wrapping material from said reel 1 to a position in front of said plate, and a paper threading device for engaging and pushing the the wrapping material has been folded back on 3 said device, said device including a semi-rigid metal tape.
3. The combination with a stationary plate, of a support for a reel of wrapping material, means for guiding the wrapping material from said reel to a position in front of said plate, and a paper threading device for pushing the wrapping material along said plate after the leading end of the wrapping material has been folded back on said device, said device including a coiled semirigid metal tape provided with a feeding head on its leading end, and manually operable means for uncoiling and advancing said tape to cause said head to engage the wrapping material and feed it along said plate.
4. A paper threading device comprising a coiled semi-rigid metal tape provided with a feeding head on its leading end, and manually operable means for uncoiling and advancing said tape to cause said head to engage and push a web which has been folded back on said head.
