Still another ob ect-of the invention is to provide a means or quickly and effectively drying theadhesive material. 1 g

-The invention consists ina machine for forming a moisture-resisting tubing of sheet material around firework fuse material as set forth in the following specification and par.- ticularly as pointed out inthe claimsthereof. The machine is an improvement overa ma chine for which I have applied for Letters Patent of the: United States Serial No. 526,108, filed March as, 1931. 7

Like numerals refer to like parts through-' out the several} views of the drawings.

, In the d-rawings,;l2 is a frame constructed in the form of a rectangular plate, and 13 and 14 are strips vof sheet material. preferably paper,- Which are led from rolls'of said material to a point above one end of said frame. The strip'of paper 13 is preferably wider than the strip 14, and the latter strip is treatedwith or constructed of a material which will render itmoist ure proof. The str ps of

paper

13 and 14 are fed between a pa1r of verticalv guide members 15, preferably formed of rubber and mounted upon vertical 1 studs 16. w

1 From, the .guide members15, the. strips of material 13 and 14-passto and'through a frusto-coni'cal forming member 17 which is mounted'upon a bracket 18 in turn supported upon the frame 12. The frusto-conical forming member17 tapers in the direction toward which the sheets of material are fed. Mounted in the frusto-conical member 17 and positioned eccentrica-ll-y, with relation thereto is'a frusto-conical guide member 1-9, the outer periphery of which is secured to the. inner surface of the frusto-conicalmember 17. By

mounting the member19 within the member 17 acresoent-shaped space 20 is formed within the guide member17 audit is through this spacethat the strips of

sheet material

13 and 14 pass; andwhen said strips emerge from the forming member-l7 their adjacent faces contact with each other and they are bent in semi-tubular form; see Figs. 5 and 6. d d From the forming member 17 the strips of sheetfnaterial Band 14 pass to a spiral forming member "21 mounted upon .a bracket 22 in turn supported upon the frame-12. The forming member 21 tapers longitudinally thereof in the direction toward which the 1 strips of sheet material are fed and is spiral in cross-sectlonal con-tour, see F g. 7 As the, I

strips of sheet material are fed into the forming member 21 they are progressively bent into spiral form and reduced in diameter, and when said strips emerge from said member, the narrow strip 14 has assumed a tubular formation and one edge portion of the wide strip 13 has assumed a tubular formation around the strip'14, while the remainder of the strip 13'eXtends laterally therefrom at 23, see Fig. 8.

From the forming member 21 the partially formed tubing extends into and through a reservoir 24 for a suitable adhesive material which contacts directly with allof the exposed portion of the strip 13, which includes both faces of the laterally projecting portion 23 of said strip. In passing outwardly from the reservoir 24 the sheet material passes through a rubber tube 25 which acts to fold the port-ion the-strip 13 against the tubular portion of said strip and at-the same time wipe the tubing and limit the amount of adhesive mate'rial'which is allowed to adhere to the outer periphery of said tubing. 1

From the reservoir '24 the completely formed tubing 26 passes into and through a drying device 27 embodying therein a container 28 in which a quantity of water is located. In passing through thedrying device 27, the tubing 26 passes through a rigid tubular member 29 which prevents the water from contacting with said tubing. The container 28 restsupon an electrical heating apparatus 30 of any suitable construction and the water within the container 28 is heated thereby. As the tubing 26 emerges from the tubular member 29 it passes into and through another tubular member 31 constructed of rubber, wliich exerts a yielding pressure against the peripheryof said tubing.

The strips of sheet material13 and 14' are fed through the forming members 17 and 21, reservoir 24-and drying device 27by means of feed rolls32and 33 which are located upon opposite sides of thecomplete'd tubing 26 adjacent to the point where said tubing emerges from the tubular member 31. The

feed rolls

32 and 33 are formed of rubber or other suitable material which will frictionally engage the tubing'and 'exerta strong pulling action thereon. Therolls 32 and 33 are rigidly fastened t o"'a- 'driving shaft 34,

and couutershaft35 respectively,and said shafts are'connected together and rotate in unison by gears 36 and 37.2 The driving shaft 34 may be. driven in any suitablelmannerg' To nevent the completed tubing 26 from v collapsing between the feed rolls 32 and 33 a tubular member 38 is positioned within the completed tubing at the point where said rolls press tliereagainst. The tubular member 38 is prevented from being drawn forwardly with tie tubing 26 by being connected by means of a wire 39 with the forming member 17, where a hook portion 40f0rined upon the of a guide roll 41 mounted upon a bearing 42, being guided to said guide roll through a tubular guide member 43 mounted in a bracket 44 supported upon the frame 12.

The general operation of the mechanism hereinbefore specificallydescribed is as follows :Assuming that the strips of

sheet material

13 and 14, positioned as illustrated in Fig. 2, have been threaded successively through the forming members 17 and 21, reservoir '24, rubber tube 25, rigid tubular member 29 and rubber tube 31, and at the same time formed into a tube around the continuous piece of fuse material A,'thefeed rolls 32 and are. started-in operation to pull the strips of sheet material through the members mentioned. As the strips of sheet material pass through the frusto-conical forming member 17, the flat strips of material are bent into semi-tubular form, with the side strip 13 partly enclosing. the narrow strip 14, and at the same time both of the strips of material are caused to taperslightly in the direction toward which they arefed. From the forming member 17 the partially formed tubing is fed to the spiral: forming member 21,-where it is still further bent to entirely enclose the fuse material A and to force the portion 23 of the strip of sheet material 13 against the tubular portion of said strip and also to wipe the excess of adhesive from the peripheryflof thetubing.- The tubing then passes to the drying device 27where upon passing through the rigid tubular member 29 it is subjected to a sutficientamount of heat to cause the adhesive material to dry quickly, and finally, the tubing passes through another rubber tube 31 where itreceives a final wiping operation. As the tubing 26 is fed through the various forming members'the endless piece of fusematerial A will be pulled along in unison with the tubing and the strips of

sheet material

13 and 14 will be progressively formed around thefuse material.

It. is evident that. if it is so desired, the

feeding mechanism for the tubing may be omitted and the tubing fed through the apparatus by hand.
