Application May 1, 1928, Serial No. 274,331 In France June 10, 1927 21 Claims. (CI. 93-81) My invention relates to a process for the manufacture of strong tubes of paper or like substance, more particularly of tubes adapted for the manufacture of bags, which may contain a rather considerable weight of material, and in particular of the so called valve-bag type. The invention relates'also'to a machine by which the said process may be carried into effect.

For the purpose of providing rigid containers, it has already been proposed to manufacture paper tubes by winding a band of paper upon itself in several turns, the difierent layers being made to adhere strongly together by means of a continuous coat of adhesive material spread over the whole surface.

Whenapplied to tubes of large diameter, such a process obviously causes a great waste of adhe-v sive; moreover when strong bags are to be made from said tubes, which requires the use of a thick paper, the uninterrupted coat of adhesive gives to the finished tube a hardness or stiffness whereby the manufacture of a bag is made very difflcult; in particular, the manufacture of the socalled valve-bags is made quite impossible.

One object of .my invention is to provide a process of making paper tubes of great capacity and strength whose walls will however have a great suppleness allowing to easily manufacture them into valve bags. Another object is to produce'tubes of the aforesaid character which will comprise several convolutions and will be far more resisting than the similar bags heretofore known which are made of. a number of several independent sheets pasted together end to end.

Another object is to provide a machine of a very simple and inexpensive character for carrying out such a process and which will however operate in an accurate and reliable manner.

With these and other objects in view, my invention consists of certain features as 'well as of the combination and arrangement of partshere- :after described andmore particularly-pointed out in the claims.

A preferred embodiment of a machine according to my invention is illustrated in the accompanying drawings in which:

Fig. 1 is a general elevational view. of the machine, and

Fig. 2 is the corresponding side view.

Fig. 3 is a detail view of the winding mandrel, with parts broken away. Fig. 4 isa detail view of the pivoted'bearing.

Fig. 5 is an elevational view of the device for forming the bellows parts, and

Fig. 6 is a section on the line 6-6 of Fig. 5.

In the example herein represented, the machine comprises a base plate or table I mounted on two cross-braced legs 2. The two supports 3 and l which are mounted on the said base plate carry the main shaft 5, by means of the two bearings O 5 and I whereof one, 6, is pivotally mounted, as will be hereinafter described in detail. Upon the shaft 5 is mounted the mandrel ll consisting of a sheet 9 of aluminium or other material wound upon the plates I0 secured to theshaft 5. A por- 10 tion of the sheet 8 forms a shutter l I, one of whose edges is hinged to the stationary part of the mandrel 8 in such manner (for instance) that it will rotate on an axle I! which is flush with the external surface of the mandrel and is parallel with the shaft 5. v The other edge is supported by the eccentric discs l3 secured to a shaft I mounted in suitable supports or bearings secured to the end-plates iii. ,A handle I! mounted on the end of the shaft It serves to rotate the latter and hence to control the said shutter which is thus movable at will in the interior of the mandrel 8. The edge supported upon the disks is bevelled and may fit upon the corresponding edge of the fixed part of the mandrel 8, and these two edges may be faced with india rubber, felt or like flexible substance by which the adhesion will be increased. The greatest distance between the axis of. revolution of the eccentric discs I3 and their periphery is greater than the distance between said axis and the inner surface of the mandrel engaged by the periphery ofthe discs, so that, by turning in one direction the shaft ll through the handle [5, the discs will act to press the free edge of the shutter upon the correspond:

ing edge of the mandrel whereby the sheet of paper will be firmly clamped to the mandrel. and by rotating the shaft in the opposite direction the shutter will be moved away from the indeformable part of the mandrel, whereby the sheet of, paper 40 will be released. a

Upon the shaft 5, which extends beyond the support 4, is loosely mounted the driving pulley It. A slidable sleeve H which rotates with the shaft 5 serves to connect together the said shaft by means of a coupling of the friction or other type. The sleeve I1 is also secured to a tapered member l8 coacting with a stationary tapered member l9.

Due to the friction between these two tapered members, the shaft 5 can be braked and can be instantly stopped. The end of the shaft I is mounted in a third bearing 20 which is secured to a support 2| mounted upon the base plate I. A fork 22 rotatable on an axle 24 mounted on the support 2| is engaged in a groove 23 in the sleeve H; the other end of said fork-urged by the spring 25carries a roller 26 coacting with the cam 21 keyed to shaft 28 rotatable in the support 2|. The said cam carries a boss which makes contact with the roller 26 and thus oscillates the fork 22. By a suitable fastening device 22 --for instance a rod or pin--the fork 22 can be held in the uncoupling position. A chain 29 is disposed upon the chain wheels 38 and 3| mounted respectively on the shafts 5 and 28, so that the shaft 5 can drive the shaft 28. The diameters of the said wheels are such that the ratio of the speeds of rotation will depend upon the number of revolutions to be made by the said tube.

If for instance the tube is to comprise four thicknesses of paper, the diameter of the wheel 38 will be A the diameter of the wheel 3|, so that the shaft 5 will make four revolutions while the shaft 28--and with it the releasing cam 21- makes only one revolution.

The two rollers 32-33 are mounted upon the respective shafts 34-35 which are parallel to the shaft 5 and are disposed on either side of the vertical plane passing through the said shaft. The said rollers are guided in the vertical guides 36-31 by the sliding members 38, and are supported only at the ends by means of the rollers 39 resting upon the cams 48. A vessel 4| containing the adhesive paste is disposed below the rollers 32-33 and it is mounted upon the blocks 42 disposed on the supports 43-44 which are secured to the base plate I and in which are formed the guides 3631. The said cams are mounted upon the ends of the shafts 45 rotating in blocks which are respectively slidable in the guides 3631 and are supported by the screws 46; said screws can be turned in the nuts which are mounted on the respective supports 43 and 44 and thus regulate the vertical position of the shafts 45. The chain 41 is placed upon the wheels 48 which are mounted at one end of the shafts 45 and upon the wheel 49 which is disposed upon an intermediate shaft 58 mounted in a bearing 5| secured to the base plate I.

Upon the shaft 58 is mounted a' chain wheel 52 which is'connected by a chain 53 with a like wheel 54 mounted, on the shaft 5. This arrangement provides for the control of the rollers 32 and 33 in a synchronous manner both in mutual relation and also in relation to the shaft 5. The diameters of the chain wheel are chosen in accordance with the speed of rotation which is to be given to the shafts 45, i. e. according to the number of turns which the said mandrel is to make between two successive rising movements of a given pasting roller.

Upon the support 43 is also mounted the movable bearing 6 above mentioned, which comprises the semi-circular bearing 55 mounted upon an arm 56 pivoted at 51 to a horizontal support 58 secured to the support 43. The arm 56 carries a projection 59 which may be inserted under the hook 68 which is pivoted at 6| to the support 58 and is brought into the vertical position by the spring 62. A hand-controlled rod 63 is pivoted at 64 to the arm 56, and its end rests upon the hook 6|; the spring 65 holds the same in the vertical position. v v

Below the said mandrel, and in the vertical plane passing through its axis, is disposed a jointed parallelogram whose extended small sides 66 are each terminated by two divergent branches carrying the rollers 61. One of the long sides 68 of the said parallelogram is rigidly secured to the base plate I the other side, which is extended, serves as a controlling bar 68". In this manner the rollers 61 may be brought into contact with the mandrel 8 which they support when the bearing 6 is removed; a suitable known device (not shown) holds the said parallelogram in the proper position.

The two uprights 68 mounted on the plate I comprise at the upper part two guides 69 in which are rotatably mounted the two rollers 18 and 1| betweenwhich is circulated the paper or like material to be wound. Upon the shaft of the lower roller 18 is mounted a hand wheel for the hand control of the device. The two arms 12 mounted on the brackets 68 carry an independent roller 13 which serves as a guide for the said sheet to be wound;.this sheet proceeds between two closely-spaced strips 14 which are suitably secured to the brackets 68 and also serve for supporting and guiding purposes when the paper is out 01f by the knife when the tube is finished.

Upon the legs 2 are mounted the supports 15 in which is rotatable the roll of paper or like material employed. Upon the said roller is applied a shoe 16-of india rubber, fibre or the like; the said shoe is mounted on an arm 11 pivoted to an axle 18 secured to the main frame of the I machine.

A spring 19 is attached at one end to the arm 11 and at the other end to a sliding member 88 movable in a guide 8| which is secured to the main frame and constantly presses the shoe 16 upon the said roller. The sliding member 88 is axially movable together with a shaft 82 which comprises a threaded part turning in a stationary nut 83; upon the end of said shaft is mounted a hand wheel or crank 84 at the front of the machine.

On the same side of the machine as the movable bearing 6 is disposed perpendicularly to the axis of the machine a vertical frame 85, one of whose vertical uprights 86 is situated in the middle vertical plane of the mandrel 8. Upon the said upright is pivotally mounted the frame 81, in each of whose cross-pieces 88 is formed a longitudinal slot 89 adapted for the insertion of the rounded edge of one of the bars 98. The said bars are connected with the frame by the pivoted'levers 9| in such manner that they are displaced while remaining parallel. At the ends of the said bars are pivotally mounted the two operating levers 92-93; the lever 92 carries a stud 94 slidable in a long guide 95 formed in the other lever 93. In the axis of the movable frame 81 is disposed a round rod 96 on whose end is mounted a hand wheel or crank 91, said rod being rotatable in supports secured to the uprights 98. The two cross-pieces 99 are rotatable together with the rod 96, and carry at their ends roller 13 and between the rollers 18 and 1|, as

well as between the two blades of the guide 14; the edge of the paper is inserted through the longitudinal slot in the mandrel 8, and if necessary. the paper is drawn out by turning the roller 18 by means of the hand wheel provided for the I purpose.

By turning the handle I5, the operator causes the said edge to be seized between the shutter II and the stationary part of the said mandrel 8. The machine is now ready to operate. The 75 leasing the fork 22, which is drawn 'backby the spring 25 and slides the sleeve l1 upon the shaft 5, and said sleeve thus engages the pulley It. The mandrel 8 now begins to rotate and the sheet F of pape ifis wound thereon. The

rotation is communicated to the shafts 45, carrying the cams 40', by means of. the chain 53 coacting with the wheels 48 and 49. The said cams 40 will raise at the propertime the pasting rollers 32 and 33 ,Which are immersed in the paste bath M. g By means of the screws .46, the vertical position of the shaft 45 is regulated in such manner that the, said pasting rollers will make a slight contact with the sheet of paper wound on the .mandrel when they are in the upper position. v

In the present example, the cam corresponding to the pasting roller 32 will raise this roller shortly before the mandrel 8 has made half a revolution, whilst the cam. corresponding to the pasting roller 33 is displaced by of a revolution with reference to the precedingcamQand it raises the roller 33 shortly after the mandrel 8 has made three, complete revolutions, the

speeds of the cams and of the said mandrel having a ratio of 1 to 4.

The outline of the said cams forms an acute angle, so that the contact between the said past; ing rollers and the sheet of paper will last'for a very short time, and the rollers will leave upon the sheet only a'narrow band of paste. Obviously, the said cam may have a very different outline, and may provide for ajcontact between the pasting rollers and the sheet of paper which corresponds to any desired fraction of a revolution of the said mandrel.

When the said mandrel has completed its fourth revolution, the'cam 21 will have made a complete revolution,'since thediameter of the wheel 3! is four times that of the driving wheel 39. The boss mounted on the said cam makes contact with the roller 26 and turns the fork 22 which actuates the sleeve 11. This latter brings the braking cone IB'into contact with the stationary cone I 9, and in'this manner the whole machine is instantly stopped. The-fastening device 22# allows the fork, 22 to be ,heldin. the re leased position. The operator cuts off the sheet by holding his knife against theguide 1 4. The handle I5 is turned so as to allow the shutter H to. drop in the interior, thusjreleasing the inner edge of the resulting paper tube.

To remove the said tube, the controlling bar 68 is pushed out, and this brings the rollers 61 into contact with the mandrel 8. A suitable fasagain placed under the hook 6|. The mandrel being again supported by the bearing ,6, the operator draws upon the bar 68*, thus separating the roller 6'! from the mandrel 8, and the machine is ready" for the next operation;

When it is desired to manufacture tubesof the bellows type, themovable frame 81 is brought mid linel with the axis of the-niandrel by tuniing the said frame upon the upright 96. The operator directly slides the tube of the mandrel uponthis frame which he then brings intothe plane of thestationary frame 95. By means of .5 the handle 91 he turns the frame consisting of therollers I90 and the cross-pieces 99, so that the said rollers will-make contact with the wall ,of the sack which they, stretch symmetrically with-reference to the plane of theframe 81. By 10 i actuating the lever 93, the bars 90 are inserted s at the same time intothe corresponding slots 89 oi the cross-pieces 88, thus forming the ,desiredbellows portion. The resultingtension on' thewall'of the saclcwill pivot therollerframe 15 and thus bring itintothevertical plane. The finished tube can thus be readily removed after 7 having again brought the frame out of the plane of the frame 81. v

The functioning of the brake affording the 20 regular unwinding of the rollof paper will be readily understood} The spindle 82 serves to regulate the tension of the spring!!! by more or less separating the block 80, according-to the diameter of the roll of paper. 25
