To all whom zit may concern.'

Be it known that I, WILLIAM DICHMANN, a citizen of the United States, residing at Oshkosh, in the county of Winnebago and State of Wisconsin, have invented new and useful Improvements in Machines for Making Bottle- Vrappers, of which the following is a speciiication.

My invention relates to a machine for the manufacture of bottle-wrappers used in packing bottles to prevent breakage.

r1`he object of my invention is to provide a continuous method of making, forming, and

crimping circular crimped bottle-wrappersand to provide a continuous machine that will insure a maximum rapidity of manufacture.

My invention consists of certain other new and novel features of mechanism and construction, which will be hereinafter more speciiically set forth and described.

In the accompanying drawings, Figures 1, 1, 1b are views arranged on successive sheets showing my improved wrapper-forming machine in side elevation. Figs. 2, 2", and 2b are similarly arranged upon successive sheets, showing a top plan view of the machine, portions of the frame above the main frame being shown in section. Fig. 3 is a transverse vertical section of the machine, taken upon the line A A of Fig. 1. Fig. 4 is a similar vertical sec'- tional view on the line BB of Fig. 1. Fig. 5 is a similar vertical sectional view taken upon the line C O of Fig. 1l. Fig. 6 is a transverse sectional View through the strip of wrapping material produced by the machine before it is formed into a completed wrapper. Fig. 7 is a vertical sectional view taken centrally through the feed-rolls of the mechanism. Figs. 8, 9, and 10 are detail sectional views of the principal successive forming-rolls, showing their relation to the central stationary former. Fig. 11 is a side elevation of a completed cover. Fig. 12 is a transverse sectional view through the same in its cylindrical form looking toward the crimped neck portion thereof. Fig. 13 is a side elevation of the cutter employed at the end of the wrapper-forming machine for cutting' the wrapping material ofi' .in proper lengths.

1 1 represent the top rails of the frame, and 2-represents one of the bottom rails.

3 3 3, &c., represent the upright standards of the frame.

4 4 4, Sac., represent the cross-rails of the frame.

5 represents the main shaft.

rlhe power is applied to the pulley 6.

The bottle-wrapper is composed of top and bottom sheets of paper 7 7 and an intermediate lilling of flexible material 8'.

9 represents the roller for the bottom paper, and 10 represents the roller for the top paper.

11 represents an inclined trough,upon which the flexible filling 8 is spread and fed to the machine on top of the endless belt 12.

13 is an inclined support for the endless belt 12.

14 is an adjustable tightener to regulate the tension of the belt 12.

The filling 8 passes from the endless belt 12 onto the lower strip of paper 7 over the roller 15.

16 represents the driving-roller for moving the endless belt 12.

17 is a pressure-roller to properly compress the iiexible material 8 as it passes on the endless belt 12.

18 represents bevel-gears transmitting' the power from the main shaft to the bottom forming-roller 19, Fig. 3.

21 represents gears transmitting the power from the forming-roller 19 to the top forming-roller 20.

22 is a sprocket that operates the endless chain 23 to drive the pressure-roller 17.

24 represents the sprocket attached to the forming-roller 17, which operates the endless chain 25, passing round the idler 26 and over the sprocket 27, which is attached to the roller 16, that drives the endless belt 12.

The lower forming-roller 19 is recessed at 28, and a corresponding projection 29 in the top forming-roller 20 travels in said recess for the purpose of forming in the bottom paper 7 a trough 30 to receive the flexible tilling 8, Fig. 6.

31 represents a recessed guide-trough in which the lower strip of paper passes as it is carried along, the flexible material being discharged upon the paper at 15.

32 represents a pressure-roller to confine the flexible material as it passes along upon the bottom strip of paper 7.

33 33 are side boards each side of the trough to confine the flexible material as it .passes along.

The top strip of paper 7 is drawn from the roller 10, round a flange guide-roller 34 and over the glue-rollers 35 35, which operate in IOO the glue-pan 36 and supply a continuous strip of glue against the under side of the paper at each edge.

37 is an adjustable scraper to regulate the supply of glue upon the rollers 35 35.

The paper 7 is drawn round the rollers 38 38 and over the flange guide-rollers 39 39 and between the pressure-rollers 40 41, where it is pressed against and attached to the bottom strip of paper 7, containing the flexible material 8, as it passes along. The pressure-rollers 40 41 serve also to draw the two strips of paper 7 7/ from their respective rollers 9 and 10.

42 represents a sprocket-wheel upon the same shaft as the roller 40 and receives the power by means of the endless chain 43, connecting with the sprocket 44 upon the same shaft as the roller 19, which is geared to the main driving-shaft .5 by the bevel-gears 18.

45 is an adjustable idler for taking up the slack of the endless chain 43.

46 is a sprocket upon the same shaft as the roller 32, which is also operated by the endless chain 43.

For the purpose of keeping the strips 7 7, which inclosc the flexible material 8, at all times tautI provide a ratchet-wheel 47, keyed to the shaft 48, which carries the recessed roller 40. The spring-actuated pawl49, which is rigidly attached to the sprocket 42, operates on the teeth of the ratchet-wheel47. The sprocket 42 is permitted to turn upon the hub of the ratchet 47. As the feed-rollers, which will be hereinafter mentioned, operate to draw the paper through the machine this pawl-andratchet mechanism permits the packing-tube to be drawn forward, so as at all times to be taut. I regard this as an essential feature of my invention, as without the operation of the pawl and ratchet the action of the endless chain will not provide a proper tension. In order to gain this tightness, the feed-rollers hereinafter mentioned are constructed of a diameter slightly greater than the radius of the pressure-rollers 40 41 and have a double revolution, so that they will operate faster in pulling the strips along, and thereby gain the necessary tightness, which is relieved automatically by the operation of the pawl and ratchet, the ratchet advancing a tooth from time to time when the pull becomes too strong. The rollers 41 41 are idlers revolving loosely upon the shaft 50 and are held in a lateral position by the collars 51 51 5l 5l rigidly to the shaft 50.

In order to insure the requisite pressure to properly set the glue to adhere the two edges of the strips of paper 7 7', I provide pressuresprings 52 52, which are adapted to press the boxes 53 53 downwardly. The set-screws 54 54 are provided to hold and regulate the pressure of the springs. After the two strips of paper are glued and pressed together the double strip inclosing the flexible material is drawn over the glue-roller 55, which operates in the heated-glue Vat 56. This distributes a narrow strip of glue along one edge of the united strips upon the bottom.

57 is a roller of the same size, attached to the same shaft as the glue-roller and acts as a support for the united strips of paper as they pass along.

58 is a scraper to regulate the supply of glue upon the roller 55.

59 is a loosely-journaled roller for the purpose of properly carrying the united strips downwardly against the glue-roller 55. The united strips are then drawn along by the feedrollers and rolled into tubular form by means of the several sheaves hereinafter mentioned.

60 represents a cylindrical interior former suspended from the cross-cleats 6l 61, Sac., which are supported by the rails l 1.

62, 63, and 64 are exterior forming-rollers, sequentially convergent, over which the united strip of paper is drawn.

65 65 65, &c., represent spring-actuated selfadjusting' sheaves, as shown in detail Fig. 5. These sheaves operate to gradually turn the united strips into a circular form round the interior former 60.

66 represents anarrow spring-actuated selfadj ustingsheave adapted to press downwardly upon the tubular cover against the lower sheave 65 to press the glued edge over the opposite edge and cause it to properly adhere to form a tube, the glued edge having been previously coated by the glue-roller 55. In the process of turning the fiat strip into tubular form the trough or recess 30, previously provided in the bottom strip 7, is taken up. This provision of a trough or recess in the bottom strip is necessary in order to furnish an extra width to be taken up in the process of bending or rolling the united strips into a tubular form; otherwise the lower or outer strip would tear and the upper or inner strip would buckle.

67 67 represent the feed-rollers, which draw the finished tube and feed it to the cut-off. As the tube passes between the rollers it is pressed into a flat shape and carried along the guideway 68 to the revolving cut-off wheel 69. The cut-off wheel is provided with two oppositely-loeated.shear-knives 70 70, which impinge against the cutting edge o'f the stationary cutting-plate 71, attached to the end of the guideway 68.

72 represents bevel -gears conveying the power from the main shaft 5 to the lower feedroller 67, which is geared to the upper feedroller by the gears 73 in order to secure a positive revolution of both rollers. The springs 74 74 serve to press the upper roller downwardly to provide a proper tension.

75 75 are adjusting-screws to hold and regulate the springs 74 74.

'Ihe pressure-rollers 67 67 are geared so as to revolve twice as fast as the pressure-roller IOO 40 and are constructed of a diameter slightly in excess of the radius of the -pressure-roller, so as to constantly pull the strip taut, as hereinbefore described. The feed-rollers 67 67 thereby always provide a draw, which is relieved automatically by the ratchet-wheel 47, as hereinbefore described.

76 represents a shaft journaled to the frame 1 and operated from the main driving-shaft 5 by means of the gears 77. The shaft 76 operates the crimping device. The crimping device consists of two cams 78 78, between which the circular bottle-cover is drawn after it is cut off by the cutting-wheel 69. The cams are operated toward each other by the gears 79 79, and the motion is transmitted by means of the intermediate gears 80 81. The crimping-cams are provided with both a top plate 82 and a lower plate 83, which support the cover as it is being drawn through. The action of the cams 78 78 crimp the top portion of the cover84, as shown in Figs. 7 and 8.

In making wrappers with the machine herein described rolls of paper for the outer and inner portions of the covers are mounted upon the rolls 9 and 10, the former being mounted in the lower portion of the machine, so that the web of paper drawn from it may be led to the under side of the assembled portions of the wrapper, while the other web being mounted above the machine will form the cover or top of the completed strip. The web of paper taken from the roll 9 is led to forming- rolls 18 and 19. The passage of the web of paper between said rolls forms a longitudinally-extending trough or depression in the paper. The trough thus formed affords ample space for the lling placed between the upper and lower web of the paper and also provides sufficient slack for permitting of the combined strips being turned into a cylindrical form Without crowding or crimping the inner strip of material. The strip of paper thus formed is led beneath the end of chute 11, the iiexible filling material8 Abeing permitted at this point to fall upon the upper surface of the lower web and iill the recess or trough formed therein. The strip with the filling material upon it then passes beneath the roller 32, which presses upon the filling material in such a manner as to press and partially pack the same in place. The lower web thence passes to the rolls 40 and 41. UJ ust before entering these rolls the upper web 7 meets the lower web, and the two webs pass through the rolls 40 and 41 together. Before the web 7 reaches the said rolls 40 and 41 it isvpassed over gluing-rolls 85, by which it receives adhesive megrial upon its edges and upon one face theref. As the-two webs pass through the rolls 4G) and 41 the edges thereof are pressed togethier by the said rolls, as clearly illustrated in Figi'. 4, and since the upper web is applied Withjits glue the adhesive material face downwardly the said adhesive material will be brought between theedges of the strips as they are pressedtogether and secure them against separation. The combined webs, with the filling material between them, form a packing-strip, which is now in readiness for bending and securing in a cylindrical form. In order to provide means for holding the strip of material in its cylindrical form, glue or adhesive material is applied thereto,and although it may be applied to bothv edges of the strips of the material it isV preferably applied to one edge only. The adhesive substance or glue is placed upon the strip of material by passing it from the rolls 40 and 41 over a glue-vat. Arranged above the glue-vat are rolls 55 and 57, one only of which extends into the gluevat 56. Both rolls are needed to hold the packing-strip in proper position; but since it is only desired to apply the glue to one edge of the strip it is suliicient to have the roller 55 extend into the adhesive material. As the packing-strip passes over the rolls 55 and 57 the glue will be deposited by the roll 55 upon one edge of the combined strip. The packing-strip is now in readiness for formation into a cylinder, and it is led from the gluevat to the roll 62 and is passed beneath the stationary former 60. The roller 62 is formed with a concave periphery and begins the'operation of curving the packing-strip longitudinally. f From this point the web is extended to successively converging rolls arranged about the former 60. Thus from the roll 62 the strip passes to the roll 63, which is concaved to a greater extent, and from the roll 62 the strip passes to the still more concaved roll 64. At this point the strip will be pressed around the lower half of the former 60. The strip then. passes along the former to the rolls 65, which are arranged to bear upon the sides and top of the former, and the final pressureroll 66, arranged directly upon the top of the former 60, will press the glued edge of the material strip upon the other edge thereof, so as to hold the said strip in its cylindrical form. rlhe packing-strip is now in readiness for cutting to reduce it to proper lengths. To facilitate the cutting operation, the strip is preferably flattened, and for this purpose is passed between the rolls 67, which press the cylindrical strip of material at and then feed it into the trough 68, which leads to suitable cutting mechanism. The rolls 67 not only perform the function offlattening the packing material for thev cutting apparatus, but also grip the packing material with suiicient tightness to feed it through the machine, pulling it through the successive rolls and treating apparatus above described. pose that the rolls 67 are positively driven by the gearing hereinbeforedescribed which connects it with the shaft 5. The iiattened packing-strip is forced along the trough 68 and through the open cutter-wheel 69, where it is cut off in suitable lengths by the knives 70.

IIO

It is for this pur- ISO The movement of the knife-wheel is so timed with respect to the feed of the packing material that the said material will only be engaged by the successively-presented knives after the said material has been fed through the open portion of' the wheel asuitable distance to form the right length of bottle-wrapper. As the successive wrappers are cut by knives their ends are gripped between the crimpingcams 78. The cams .7 8 are formed with crimping' portions which extend only a short distance around the periphery of the body portions of the cams, as will be herein seen by reference to Fig. 2b. The movement of' the cams is so timed with respect to the cut of the packing' material that when the material is severed from the main strip the outer end of the cut piece will be gripped between the projecting' crimping portions, which will contract and crimp the end of the severed wrapper for a short distance-that is, suiiicient to `[it upon the neck or tapering portion of a bottle. The remaining periphery of' the cams 78 will not act upon the wrapper, but the wrapper will then be in readiness to be dropped from the machine and can be used for applying to bottles to pack the same.
