TUBE-MAKING MACHINE.
vApplication filed June 4,
This invention relates to tube making machines, and more particularly to machines for producing tubes from which shot shells are made. High grade shot shells must be of uniform diameter and present a smooth exterior, free of all roughness due to the wrinkling of the paper from "which they are formed. Moreover the convolutions which are past-ed together must be tightly wound and the outer edge of the sheet closely laid down in adherent relation to the underlying body portion.
- The present invention is in a sense an improvement of the machine set forth in U. S. Letters Patent No. 537,560 to C. S. Bird, dated April 16th, 1895, to which reference is hereby made.
The main object of the invention is to provide means to moisten that portion of the sheet which forms the outermost convolution (in whole or in part) prior to the application of the adhesive thereto, whereby such portion of the sheet upon being wound about the previous convolutions on the mandrel will lie flat and not curl up or blister. Dur ing the wetting or moistening operation, the sheet, or more particularly, the section which produces the final outer faceof the tube may be colored by utilizing the water as a'carrier for the paint or pigment.
A furtherobject of the invention resides in the provision of means for effecting a withdrawal to a greater or less extent of the presser or smoothing bar or element during the winding of the outer end of the sheet to place, thus ensuring the retention of a sufficient amount of paste beneath such outer ends as will effect proper adhesion.
With these and other advantages in view as will hereinafter appear, reference willbe had to the annexed drawings wherein:
Flg. 1 1s a top plan view of the machine; Flg. 2 an end elevation: i
Fig. .3 a vertical section view on the line 3-3. of Flg. 2'show1ng the moistening pad and the overlying presser bar for forcing the sheet against the pad;
Fig. 4: is a detail sectional view on the line 4;4.- of Fig. 3, and y I i Fig. -5 a perspective view of the machine with the rear portion broken away.
The sheet which is to be wrapped is denoted by S and such sheetsare placed upon a table 1 and advanced against a stop 2 mounted on a shaft 3 adapted to be rocked byna hand'leve gt, The sheetwhen the stop 1924. Serial No. 717,866.
is raised is grasped between endless belts or tapes 5 and 6, and T and 8 arranged in pairs one above another, the lower belts passing about a driven roller 9 and idler rollers 10 and 11, while the upper ones are sustained by rollers 12 and 13 adjacent the table 1 and at the opposite end of the run by similar rollsla and 15. The sheet is advanced by the tapes or belts over a second table 16 until its advancing edge abuts a fixed stop 17 which arrests its further inove- Y ment, the sheet being squared against'the stop by the slight drag exerted by the belts.
Table 16, see more particularly Figs. 3 and at, is slotted or recessed .to receive an elongated trough shaped receptacle 18, the
upper face whereof is flush with the bed.
Said trough extendstransversely of table 16 and in line with the sheet as it feeds from table 1 so that the rear portion or edge of the sheet is passed over or lies directly above the trough. I
A suitable absorbent pad 19 is mounted in the upper portion of the trough, the upper face whereofis flush, or substantially so,
with the surface of the table 16. The lower portion of the trough is in communication with areservoir 20 through a pipe 21 so that the trough is constantly filled with liquid and the pan likewise maintained in a saturated condition. The head of the liquid may be regulatedby raising or lowering the reservoir and by filling it to a greater or less extent.
A gutter 22 having a drain opening 23 extends about the felt, saidgutter serving to draw off any excess liquid and preventing it frompassing outwardly onto the table.
, The sheet as it is passed over the pad and against the fixed stop passes below a pair of feed rollers 24 and 25 and above a similar pair ofrolls 26 and 27 which latter are constantly driven. Rolls 24 and 25 are secured to a shaft 25, the ends whereof rest in suitable bearingsformed adjacent the inner ends of a pair of substantially L- shaped arms 28 and 29. The free ends of said arms extend it inwardly above and in spaced relation to the table 16 and the sheet thereon, while the outerlower ends are secured to a rock shaft 30. Oscillating movement is imparted to the shaft through the medium of a crank arm 31 and rod 32, the lower end whereof is forked and co, -operateswith a cam 3 1.
Pivotally secured to each of the arms is alever 35 and a bar 36 is-attachedthereto,
' has said bar, as will be seen upon reference to Fig. 3 being slightly longer than the length or pad 19.
To the under face of said bar is secured a series of flexible lingers 37 formed from rubber, spring metal, or any suitable material, the lower ends of which when the bar is lowered flatten out against the underlying sheet and cause the same to bear closely againstthe pad and to hold it against the same as the sheet is fed forwardly over the table toward the winding' 'n'iandrel.
The parts are so proportioned that as the levers or arms 28 and are lowered, the fingers 3'7 contact the sheet or that portion thereof which'is over thepad after which the sheet is caught between the feed rolls and 9.5 and'the co-operatingdriven rolls 26 and 27, and by them advancedto and caght by a second series of rolls 38 and 39, and elO and ll. As the sheetis fed forwardl v the rear portion thereof isdrawn beneath the fingers which act to hold it against the moistened pad, and thus such rear portion is wetted upon its under surface and such surface colored at the same time if so desired. 1
From the last mentioned set of rolls, the sheet passes through suitable pasteapplying means as set forth in the patent. above mentioned and indicated herein in Figs. 1 and 2 by 42 and to the two part winding mandrel 4% and t5. Said mandrel is rotated by means which admit of an endwise movement of its two elements to cause a stripping of the completed tube therefrom.
The leading end of the sheet as it reaches the winding mandrel or arbors is brought into direct contact therewith by a rotary brush 46 which is moved upwardly against the sheet through the action of links 4-7, interconnected bell-cranks l8, link a9, lever 50 and cam 51 co-aeting with the latter.
Actingupon the sheet at the same time the brush is working is a presser blade preferably flexible, designatedby 52, said blade being moved up against the sheet-when the leading edge thereof gets about half way around the mandrel or arbor and is held thereagainst'until just before the last portIOIl of the sheet is wound, at which time it dropsback so as to relieve thepress'ure sufficiently as to leave enough paste upon such end portion as to ensure full adhesion thereof.
Blade 52 is carried by levers 53, one of which; Fig. 2, is connected by a link 54 to a second lever 55,which latter carries a roll '56 -co{'operating with a cam 57. Said cam is so shaped'that theaction'abo've specified place and the action of the 'pre'sser bards difl erent in that respect from-the bar 1 which it" 100 fin a e patent above-specified been found has-"a remove "too much of the" paste-mania 'eenseqaaee that the outer layer of the sheet has a tendency to blister, particularly so adjacent the end.
It has been found that by dampening the sheet as above set forth, there is less tendency for the sheet to curl or blister when the paste is applied thereto,consequently, the sheet ort-he outer end or layer thereof may be laid down upon the body evenly in proper adherent relation and without any tendency to blister or curl.
In the claims, it is to be understood thatthe use of the term moistening means, or means to apply moisture to the sheet, is to be interpreted as covering not-only the actual application of moisture but also the appilcation of a. liquid'coloring matter which moistens the sheet as well as colors it.
