MACHINE FOR MAKING PAPER TUBES.

atented July 2, 1918.

Application filed January 19, 1.918. Serial No. 212,729.

To all whom it concern:

O'r'ro HERMAN Rouss- (having declared my intention of becoming a citizen of the United States,) and a 'resident. of Philadelphia,- county of Philadel- 'phia, State of Pennsylvania, have invented certain Improvements in Machines for Making Paper Tubes, of which the following is a specification.

My invention relates to' certain improvements in machmes for manufacturlng paper tubes.

- One object of my invention is to manufacture endless paper tubes from flat strips of material fed lengthwise into the forming mechanism i i A further object of the invention is to pro-- vide means for securing the severallayers of paper forming the tube so that one section will be held firmly to another and to make a cylindrical tube by a continuous operat1on.-

The invention also relates to details of the mechanism which will be fully described hereinafter. j

In the accompanying drawings:

Figure 1 tion of the machine on the line 1l, Fi 2-; Fig. 1 is aplan view of the mac ine showing the reels and the pasting mechanism;

F'g. 2 is a side view of the roll section of the machine, I

Fig. 3 is a transverse sectional view on the line 33, Fig. 2;

Fig. 4 is anenlarged sectional view show ing the pairs-of rolls;

Fig. 5 is an end view showing two palrs ofv rolls and the tube in sectlon;

Fig. 6 is a detached perspective view showin the mandrel on which the roll is formed; ig, 7 is a perspective view'showlng the method of. forming the strips of paper in the of the formers to produce a tube. Paste, or

able bearings 6.

is a plan view of the roll. p0r-' formed, so that the j the several strips. Therolls, which finish I other adhesive material, is applied to two I of thestrips when a three-ply tubev is paste will be between the tube, are driven continuously, while the mandrel,on which the :tube is formed, is

reciprocated. The mandrel has reducedfportions and is yieldingly heldsothat the tube will be=pinched between the rolls'and the shoulder on the mandrel which causes the mandrel to move forward until the rolls are opposite the reduced portion of the mandrel,

- when a sprlng will retract the mandrel, '1eav-- ing the tube in the forward position. Thus the tube has an intermittent forward movement. Theconstruction of the machine by which this is accomplished is the main feature of the invent-ion.

Referring to the drawings, 1 is. the base of the-machine, suitably. supported,.'and on one end of the machine is a platform 2 carrying three reels 3, 4L and 5, mounted in suit- The paper, whichv eventually forms the tube, iswound onthese reels and 1s fed from these reels to the formers 7, 8 and 9 respectively. In order to apply paste, or other cementitious material to secure the several thicknesses of paper together, I provide an apparatus 10: having rolls'll and 12, and the two side stripsof paper pas'singfrom the reels {i and-5 pass through the pasting apparatus and paste is applied to the under side of each strip, so

that when the strips pass into the formers the pasted side of the second strip is applied to the outer, surface of the inner :strip, and, in. turn, the pasted side of the outer strip is applied to the outer surface of the intermediate stripso that the outside surface has no exposed pasted sections. I lay noclaim to the pasting apparatus,as any suitable apparatus may be usedwithoutzdeparting from the essential features'of the invention.

The formers 7, 8 and 9 are so made and the strips are so fed that' the joints ofthe several strips, forming the tube, willbe staggered, as shown in Fig. 8. Then the tube passes through a sizing die 13, shown in particular form of V Figs. 9', and 10, and'from this die to the rolls.

14 is the lower roll .housing and 15 is the upper roll housing. The upper roll housing is vertically adjustable and has side guides 5 iandzr and j the 5 screws 19,-Tshown by screws are beveled gear wheels 21' when withg'ears' 22 on a horizontal shaft 23 I .mounted inrbearings secured to the{.standon the Shae 2a are two hand was '24 the parts are coupled byturning either hand jwheel'the ends of the upper housingcan be moved in unison, but,, if, t be desired to move .foiiehnd 0 the'hous ingindependently ofthe other'the-eoupling' 25 is released so that, on .20

.-,terior"of the'tube. 1 Therolls- 36 and' -37 are alternately arranged, as "shown, so as to insure the compacting] ofthe strips" or plies of paper and drical shape. 'The rolls 36 are secured to shafts 46 mounted in boxes 35 located either in'the lower housing 14, or the upper housing 15 and the rolls' 37 are secured on shafts housing 14". or the upper housing 15,*as clearlyill'ustrated in Figs. 2 and 3. v

In the present instance, the lower set of shaftsis, driven froma main shaft 39 on which-is a sprocket wheel 4 A chainell passes around thiswheel and around a Wheel 42 on a worm shaft 43 on which are Worms of shafts is driven fromthe lowershafts through gearingAS and 48*. By the above .i ch u arrangement of gears,'allthe rolls are driven ,[at-th'e same speed. Other means of, driving the rollsmay be resorted to without departj ing from the main features of the invention. Each roll 36 has flanges .36 forming a deep,annula'r groove conforming to one-half and each roll 37 is of such width as to pass into thespace between the flanges Q5, .of the roll 36. The groove in the pelr phery of-theroll 37 is shallow and con- .;r r toone-half ofthe tube. j ltfwill' be not cedthat the flanges 36 of g the 'roller 3.6 bear upon the hub 30 of the roller 37, so that the rollers are held a proper dotted lines in Fig. 2,

Then the mandrel is released-and its spring 33 returns' it so that the. shoulder will be againin line with the rolls, when both the tube and mandrel'will again move forward.- This'action. is very the shoulders are as in Fig. .4,.then both rapid, the mandrel-having a reciprocating moves forward; After the tube passes between the last series'of'rolls, it enters acylindrical guide .50, which holds the tube in 'a central posithe proper length by the blade'51. This'blade is suittion, while it is being cut ofllto ably mountedso as to be moved either by hand into the cutting position, or by, automatic mechanism tripped by the tube; This latter feature forms no part of the present invention and formsthe subject of a separate application filed by me on the 20th day of February, lfZlS, Serial No. 218,292.

Each of the upper rolls is yieldingly held against-the lower rolls by springs 53, which are located upon the boxes for the shafts of the rolls and projections on the upper housing 15. The lower set of rolls'can be. adjusted vertically by set screws 54, as clearly shown in Fig. 3, and as the upper housing three strips of paper of the proper width are wound upon the reels 3, 4 and 5, and the strips from the reels 4 and 5 pass through the pasting device 10, so or'other cementitious material, to one surface of each of these two strips. Thecen- 'tral strip 30 is H passed through the former 7, and the strip from the roll 4.-'is passed through the former 8. The strip from theroll 5 is passed through the former 9.

-These formers are tapered, as shown,-and

as to apply paste,

of sa1d portions three strips pass over the mandrel and a strip bend one strip around another, and the through the sizing die 13, which tends to press the sheets together and: initially to form the tube. It will be noticed that the joint of one strip is as clearly shown in Fig. 8, and this is accomplished by feeding the first central strip so that joint will be at the top. Then the from the reel 4 is fed so that the joint will come to the right hand side and the other strip from the reel 5 will come'to the left hand side, as the present tube is a three-ply tube. If more plies are used, then additional reels are provided, as well as additional formers. After this the tube passes between the first pair of rollers 36 and 37 and then between thebalance of the series of rolls. These rolls are drivencontinuously and the tube is intermittently fed forward,

- while the mandrel, on which the tube is formed, is reciprocated.

As before remarked, the mandrel has a series of reduced, portions and taperedshoulders are formed at one or both ends so that .as the rolls rotate constantly in one direction the tube is pinched between a shoulder of the mandrel and the rolls, as showninFig. 4L, and both the mandrel and the tube will move in. the

direction of the arrow a in said figure As soon as the reduced portion of the mandrel is opposite to'the pinching point of the rolls,

the mandrel is released and its sprlng moves it in the opposite direction, as indicated by the arrow again brought into alinement with the centers of he two rolls, when the tube is again pinched and the mandrel and tube are againmoved forward in the direction of the arrow. Then the reduced portion of the mandrel is again the center line of the rolls and the tube brought in alinement with either remains stationary or is moved slightly forward, while the mandrel is again retracted. This is repeated so thatthe tube has a very rapid intermittent forward'movement, while the mandrel has a very rapi short reciprocating movement. This intermediate pinching of the tube brings the several layers close together and makes the paste adhere firmly to the sections. By having a series of rolls, it insures the pinching of the entire surface of the tube, as the surface, which would be missed by one roll, is pinched by the second, third and fourth roll. There may be'as many of these rolls as desired. 4

In small tubes, and in three-ply tubes, four rolls would be necessary for the purpose, but for the larger tubes the number of rollsmay be increased. In some cases, the number of rolls may be reduced.

In some instances, it may be desirable to locate apair of horizontally arranged rolls,

out of line with another,

Z2, until the shoulder is dtions and tapered as indicated by dotted lines in 2, at.

the end of a train of vertically arranged rolls in the manufacturefofsome types of tubes, butin the manufacturev of ordinary types. of tubes, this horizontal roll is not essential. I

By making each pair of rolls in the manner' shown in Figs/4 and 5, where the 'fiangelessroll 37 extends-into the flanged roll 36, the openmg between the rolls is .closed at the edges so as to prevent the escape of pulp, or paste, which might ooze out of the tube, as. it is-being squeezed.

It will be noticed that,the sharp edges ofthe rolls 37 fit snugly against the curved portion of the flanged rolls and, as these edges to a propersize, being made in continuous lengths, which can be cut off so as to produce tubes of any length desired and this is accomplished without interfering with the forward movement of the tube.

I claim:

1. The combination in a tube forming machine, of means for forming the tube; a pair of grooved rolls adapted to conform to the shape of the tube; reduced portion and a shoulder over which the tube passes from the forming. means; means for continuously driving the pair of rolls in one direction; and a spring tending to move the mandrel in the opposite direction, so that the tube passing through the machine will be moved intermittently forward and the mandrel will be reciprocated.
