14 Claims.

This invention relates to container manufacture and more particularly to the formation of tubular bodies for containers and the like.

It is a principal object of the invention to provide in the manufacture of tubular container bodies a simple, effective and inexpensive process for applying to a web of suitable material as fed from a jumbo roll a coating of surface protective material in predetermined spaced areas thereon followed by the cutting of the web into lengths suitable for forming the container bodies and in which the application of each of the coatings is coordinated with the cutting operation in predetermined timed relationship so that the coating is accurately spotted in desired location.

It is a further object to provide a continuous process in which a protective surfacing is present upon and substantially restricted to that part of the tubular body which is exposed upon the interior thereof by effecting application of spaced surfacings to a web of paper material and cutting the web in predetermined timed relationship with each surfacing application so that such surfacing will be accurately located in its desired relationship upon winding into tubular form.

It is also an object to provide a machine of the character described for forming tubular container bodies as a continuous operation by effecting the application of surfacing material in predetermined spaced areas to a web of paper as fed from a jumbo roll and cutting the web in coordinated relation with the application of the surfacings to provide for locating the surfaced areas upon that part of the web which will be upon the inner exposed surface of the formed tubular container.

It is a still further object to provide a simple and effective machine having provision for applying a surfacing material in predetermined in conjunction with the winding and formation 55 of the lengths of paper into the form-of tubular container bodies;

Fig. 2 is a view on a somewhat larger scale of a portion of the mechanism shown in Fig. 1 which provides for the application of the surfaclng material in spaced areas to the traveling web of paper; and

Fig. 3 is a schematic view showing an arrangement for effecting the multiple application of continuous or discontinuous coatings.

In the formation of tubular container bodies and the like, and particularly with reference to bodies having a surfacing material thereon to provide protection for the container, substantial economies may be effected if the surfacing which is provided for protecting the exposed interior of the container may be substantially restricted thereto. In the manufacture of convolute wound tubular bodies, this may be accomplished by forming the material from which the container is wound with the surfacing located in spaced areas thereon, and by then winding the material in such manner that the surfacing is made available upon the inner exposed surface of the container, leaving the remainder thereof substantially free of surfacing. Economy is effected in this way by reason of the fact that in the case for example of a convolute wound body comprising three or more plies, the surfacing material is required to cover only that part forming the interior exposed surface, with a small amount of underlap if desired, so that it need cover only approximately one-third of the total surface of the sheet of material. And further since the surfacing material is not present throughout the entire wound body, such body may be adhesively secured upon itself relatively simply and through the use of inexpensive adhesives. Where formed of paper material, and with the overlying paper surfaces in contact with each other the requirements as to character and quality of the adhesive to secure the surfaces together is relatively quite simple as compared with the necessity for adhesively securing together plies having a protective surfacing layer thereon of greaseproof or moistureproof material for example.

In the Fisher et al. Patent No. 2,163,316, assigned to the same assignee as this application, there is disclosed a process by means of which discontinuous coatings are applied to a web of paper to provide protection upon the interior of the formed tubular bodies. In the particular arrangement therein disclosed, concurrently with the application of the coatings, indexing markings such as notches are formed in the margin of the web, the web being either wound into a roll for subsequent use, or advanced without intermediate winding to the forming operation for forming the same into container bodies. In the forming operation suitable mechanism is provided for sensing the location of the indexing markings, and the web is then cut into suitable lengths with relation to the coated areas thereon. In this arrangement therefore the web itself is utilized in securing properly coordinated operation, and there is no necessary coordination either as to time or spatial relation between the mechanism which applies the surfacings and that which effects the cutting of the web.

In accordance with the present invention the entire series of operations of applying the surfacing material in spaced areas to the web as fed from a jumbo roll, the feeding and cutting thereof into lengths is effected simply and efliciently upon a single machine as a continuous definitely coordinated operation. The surfacing applying mechanism and the cutting mechanism are located in predetermined spaced relation to each other upon the machine, and are correlated to operate in predetermined time relation through suitable interconnected drive mechanism; in this way the coated web is cut into lengths suitable for winding and having the surfaced areas thereof in such predetermined relation to the sheet that each of them will be present to perform its protective purpose when the web is wound into tubular container form. Being carried out in this manner continuously and upon a. single machine, the necessity for indexing the location of the surfaced areas upon the sheet itself or for sensing their position is dispensed with, and the entire operation is simplified, and made more certain and accurate. With the several operations being carried out concurrently and by interconnected mechanisms, it is not possible for the operations to become out of step with each other, and any desired correlation may be secured and accurately maintained by suitably arranging the driving connections. Also it is not possible for errors in alignment, length of web or the like to accumulate and any such errors arising for example from change in length of the web when wet with a coating solution or from other causes are restricted at most to those occurring within a single blank length and as such are relatively quite simple to compensate for and correct.

When such mechanism surfacing applications may be effected of a character suitable to develop desired protective characteristics, such as resistance to the penetration or transudation of various solvents, moisture, grease, and the like. Likewise through such operations the sheet either with or without a preliminary coating may be treated to provide surfacings thereon consisting of one or more applications of either a continuous character or arranged in predetermined spaced relation to each other to locate the surfaced area upon or within a desired portion of the formed container.

Referring to the drawings which disclose a preferred embodiment of the invention a jumbo roll of paper is shown at ill from which a traveling web II is led, passing around fixed idler roll |2 and around a movable contact roll l3. The fixed position of idler roll l2 permits the motion of movable contact roll l3 without substantially changing tension in the traveling web N. Roll I3 is pivotally mounted as shown at H on an arm I5 supported from bracket l6 and which in is constantly driven by suitable drive means such as a common source of motive power 28, which through sprocket chain 21 drives shaft 23, this in turn being arranged to operate cam 25 in definitely coordinated relation through sprocket chain 23.

The application of the surfacing material is effected by means of a pair of

rolls

30, 3|. These rolls are mounted in horizontal alignment, roll 3| preferably being arranged to be moved longitudinally toward and away from the roll 30 and may be adjusted in predetermined accurate spacing under the manual control of a regulating device 32.

A positive drive mechanism is provided for actuating

rolls

30, 3| comprising a sprocket chain 34, suitably driven from the shaft of cam 25, and driving into a change speed device indicated diagrammatically at 35 which provides for operating a driven sprocket chain 36 at suitably variable rates of speed. Chain 36 passes over

sprockets

31 and 38, carried respectively by

rolls

30 and 3|, in the direction to provide for driving both said rolls in the same angular direction, thereby providing for opposite movement of the surfaces of the rolls at their nip. Preferably as shown the sprocket wheel 31 is of smaller diameter than sprocket wheel 38 and hence roll 30 is caused to rotate at a higher speed, approximately twice the peripheral speed of roll 3|. The peripheral speed of roll 30, from which the coating is transferred to the moving web may be regulated from a speed less than to a speed greater than that of the web, a higher speed of the transfer roll resulting in the application of a thinner coating and vice versa.

Under the control of cam 25, the contact roll I3 is periodically moved to establish a coating transferring relationship between web II and roll 30, such period of transfer preferably being arranged to continue for approximately one-third of the complete cycle so that coating will be applied to only a predetermined portion of the entire length of the blanks.

The material to be applied as the surfacing material is introduced continuously at a regulated rate of flow above the nip of the rolls by suitable means indicated at 39. The material accumulates upon and distributes itself uniformly across the nip and excess, if any, is discharged over the ends of the rolls where it falls upon a collecting trough 40 and is withdrawn for reuse through conduit 42. Ordinarily dams 4| are provided at each end of the nip to return the material in the nip. A stationary scraper or doctor member 43 tends to prevent material from being carried'around the surface of roll 3|, and another similar member 44 is provided to remove material therefrom and discharge it into trough 40 so that the surface of roll 3| as it enters the nip is substantially smooth and clean, and hence is in condition to regulate the quantity of material which is allowed to pass through the nip on the surface of the transfer roll 30.

Certain of the materials desired to be utilized in the surfacing or coating operation have volatile characteristics, and in order to limit and reduce the escape ofsuch volatile constituents and to provide for maintaining a uniform and homogeneous surfacing film upon the transfer roll, a casing 45 is provided which substantially completely encloses

rolls

30 and 3|. An opening 46 is formed in the casing adjacent one side of roll 30, and it is through this opening that the contact roll 13 effects the bringing of the web of paper into transferring contact with the roll 30 in properly timed relation to provide for applying surfacing material thereto as desired. It will be clear that the time in the cycle of feeding during which the web is thus brought into transferring contact may be regulated by varying the position of cam 25 upon its driving shaft, and the length of time during which the web is maintained in transferring relation may likewise be varied by suitable selection of the contour of the cam and the length of rise thereof.

It will thus be seen that material introduced through pipe 39 is caused to collect in a pool at the nip of the coating rolls and is formed into a film of regulated thickness upon the surface of transfer roll 30, being carried around on such surface and at the proper time and for the proper duration being brought into transferring relation with the web, the web being carried across the surface of roll 30 in a direction opposite to the direction of travel thereof as indicated by the arrows in Fig. 2, so that such regulated film is uniformly wiped from the surface of roll 30 and transferred to the web as a smooth homogeneous film of proper weight. By suitably regulating the variable speed device 35 to provide an increased or decreased speed of operation of the coating rolls more or less coating respectively will be transferred to the web. Similarly increasing the spacing between

rolls

30 and 3| will provide for the application of a heavier regulated film and the transfer of such film to the web.

The surfacing material applied by means of the application rolls 30, 3! may be selected to provide suitabl characteristics and to provide protection of the character desired in the final wound container. Also the coating may be applied in one or in a plurality of stages through the provision of additional coating applying means similar to that described above and operating in predetermined correlated relation with the web and with each other. Also the coating may be applied directly to the web of paper as initially produced, orv to a web which has been provided with a lower or base coating of suitable type. Thus as shown diagrammatically in Fig. 3, the web I passes through a first coating applying means I 0| where it may receive an extended or if desired a continuous surface coating following which it is dried or conditioned at I02, and fed to a second coating applying unit I03 which is located in definite and predetermined spaced relation with respect to the first such unit. At the second unit a further coating application is effected, in predetermined overlying relation to the first coating application, and also in predetermined relation to the length of material to be cut from the web for winding into tubular container form. The web may be then additionally treated at I04, and if desired subjected to a still further coating application at I05. Following treatment in the conditioner I06, the web is fed forwardly the proper distance and cut into lengths by knife means I01, and is then wound into the desired tubular container form upon the winding mandrel assembly I08,

the construction and operation of all of these parts being similar to that previously described herein. The several coating, cutting, and winding means are located in proper predetermined spaced relation and are coordinated in proper timed relation through a coordinating drive mechanism I09 to provide for cutting and winding the lengths with the several coated areas thereon occupying the proper desired positions within the formed tubular body.

In the manufacture of tubular container bodies adapted for the packaging of oil, grease, and the like, it is found desirable to utilize a composite coating comprising a lower coating layer having high flexibility and an overlying layer having high greaseproofness. Reference is made to Swan Patents 1,957,368, 1,957,369 and 2,039,361 assigned to the same assignee as this application, such patents showing the provision of composite surfacings of this character. In the practicing of the present invention the web as supplied from the jumbo roll may have a continuous coating of a previously applied suitable base coat as disclosed in said Swan patents, consisting for example of the following parts by weight:

Casein 321 Rubber latex-38% solids 1100 26 Baum ammonia 38 40% formaldehyde 35 Glycerine Water to make gallons 500 The overlying top coat, which is to be applied in predetermined spaced areas, may comprise a lacquer and have a composition as described in said patents. The following is an example of a satisfactory cellulose ester material which may be utilized with plasticizers and applied from solution by means of

rolls

30, 3|:

Nitrocellulose of 5 second viscosity, wet

with 30% alcohol 16.7 Amberol resin 801 5.9 Tricresyl phosphate 7.5 Benzol 38.4

Alcohol 16 Ethyl acetate 15.5

Total (parts by weight with substantially 25% solids) 100.0

When a composition of this character is applied in the manner above described a highly satisfac tory and uniform regulated film thereof may be formed and transferred to the web. Nitrocellulose of lower viscosity may be utilized in place of the above and likewise nitrocellulose having a viscosity substantially above 5 seconds may be successfully applied. Further the character and proportions of the solvents may be controlled to' or if desired the sheet may be formed intiallv with a lower continuous coating which is adapted to resist and limit the penetration of the emulsion into the body of the sheet; a suitable lower coating of this character has been found to be it starch, preferably one of the modified soluble starches which readily gels in water, or similar coating. As an example of an emulsion which produces highly satisfactory results as forming a clear coating film of plasticized nitrocellulose upon the sheet, and making a highly satisfactory greaseproof interior surfacing thereon, the following is given, the parts being by weight:

6 second nitrocellulose wet with butyl al- Solids content 26.4%.

If desired pigments may be added to produce desired color and appearance upon the formed film. For example by adding carbon black, a film is provided having a deep black color and a high gloss, the color being desirable as tending to resist deterioration of the coating under the action of light. Similarly the use of a white mineral fillersuch as titanium dioxide provides the coating with a brilliant white color.

In addition to the use of nitrocellulose as above described, emulsions may be prepared consisting of vinyl resins included in the lacquer phase either with or without nitrocellulose, such resins providing a highly pure and substantially tasteless and odorless material adapted for use in connection with food containers and the like. An example of the use of such resin follows:

Vinylite resin (Gelva 15) -1 1000 Toluol 740 Tricresyl phosphate 100 Total parts by weight 1840 The water phase comprises:

Water 613. Turkey red oil 6.13 Duponol M. E 3.1

Total parts by weight 622.2

The emulsion comprises 1840 parts of the resin solution with the 622.2 parts of water solution.

Also certain thermoplastic materials such as waxes, resins, bitumens, etc. may be applied in a melted condition, rolls 30, 3| and other associated parts being heated as by internal steam pressure, to maintain the surfacing material in a flowable and workable condition.

It is important in the formation of the surfaced areas that the freshly coated films be protected during the period of drying and setting against premature contact with any surface which might cause injury thereto. Inasmuch as the web continues its forward travel through the machine after the application of the coating thereto, to be thereafter wound into the form of tubular container bodies, it is important to provide for the drying and setting of such coating materials before damage can occur thereto. For this purpose the web after receiving the coating thereon passes into a treating chamber 50 in which suitable means are provided for treating the surface of the web to dry and set the coating. A satisfactory means for thispurpose consists in the use of infra-red lamps, arranged in a bank below the web and directing infra-red rays upon the coated surface to penetrate into the body thereof and to cause rapid and thorough drying. Suitable ventilating means may likewise be employed in conjunction therewith. While the use of such light sources is desired in view of their prompt and effective action, other suitable means may likewise be employed to produce a setting of the film, as by the use of heated air, radiated heat, etc., to render the coated web substantially non-sticky and non-adherent to the feed rolls. In the case of the application of thermoplastic surfacings, suitable cooling or refrigerating means may be supplied in chamber 50 for causing rapid setting of such coating.

After leaving the chamber 50, the web passes between feed rolls which are arranged to draw the web through the coating applying means and through the treating chamber, the coating having been sufllciently dried and set at the time it is contacted by the feed rolls 55 so that no damage is occasioned thereto.

The web then travels through an additional feed roll pair 58 and into position on the table 59 where it is subject to shearing action by the cutting means 50. Cutting means 60 is actuated by means of connecting rod 6| from a crank arm 82 suitably driven from a cam 63 mounted upon the shaft 28. Shaft 28 is arranged with suitable mechanism indicated diagrammatically at 54 for driving feed rolls 58 intermittently, providing for feeding a predetermined length of web, and then stopping the web during the actuation of cut-off means 50. Thus the operation of the shearing knife 60 is coordinated with the feeding operation in such manner that the shearing of the web in the desired lengths takes place during periods of stoppage of the feed. Suitable drive means for this purpose are described fully. in Sousa et al. Patent No. 2,163,318, assigned to the same assignee as this application. Sprocket chain 65 provides for driving feed rolls 55 at the same speed and in the same cycle of intermittent movement as rolls 58.

The shearing knife 65 is located in predetermined spaced relation with respect to the coating applying means and the cutting operation takes place in such predetermined time relation to the application of the coating that the web is definitely and accurately cut along substantially the leading edge of the coated portion thereof. Furthermore the parts are so coordinated that the operation of transferring the coating to the web takes place during the forward feeding movement, and not during a period of stoppage of feeding; hence at each period in the cycle when the feeding operation is stopped, the contact roll I3 has moved to position to space the web from the transfer roll 30, thereby avoiding application of an excess of coating material to the web at any time. Such material as remains on the surface of roll 30 during the time that it is out of contact with the web is merely carried back into the pool above the nip of

rolls

30, 3|.

Following the cutting of the web, the cut length is drawn forwardly under a guide member 10 by means of which it is kept flat, under the action of feed roll pairs 1|, l2, and if desired passed under spaced slitting knives I3 which slit the web transversely into a plurality of container blanks each adapted to be wound into the form of a container body. These series of blanks are then supplied to the grippers I5 on a winding mandrel 15, which is arranged in a suitable assembly frame 11 to be rotated through a series of operative positions. In the winding position the mandrel 16 rotates to wind the web upon itself with the coated surface of the web upon the interior, the length of the coated portion being sufiicient to overlie the entire interior surface of the body and preferably an additional portion to provide an underlap. During the winding operation adhesive may be applied thereto from a bath I8 in which there rotates a pickup roll 19 having contact with a movable transfer roll 80 which in turn is selectively brought into engagement with the outer surface of the web at a proper point in the winding operation. Since in the preferred position the web is wound so that the special surfacing is exposed upon and substantially confined to the interior of the formed tubular body and the adhesive is applied to the external surface of the web, the adhesive is almost entirely located on and between surfaces of the web which are free of such coating. Consequently such adhesive may be of relatively inexpensive material and may be applied as desired to be effective upon the entire surface of the web being wound, or only upon a portion thereof. Likewise it may be continued around the outer surface of the wound container to serve as a means for adhesively securing a label or the like thereto.

Following the winding step the mandrel assembly H is rotated to carry the mandrels successively through the series of operating stages in which the formation of the container body is carried to completion, the bodies being stripped in the final position as completely formed tubular container bodies having the protective surfacing material efiective over their entire interior surface.

The invention provides a, highly simple and effective arrangement for producing tubular container bodies from a traveling web of paper as fed from a jumbo roll, and having a surface coating applied thereto in such postion as to be effective upon the entire interior surface to afford protection thereto, and substantially restricted thereto leaving the remainder of the bodies free of surfacing and such that they may be secured quickly and easily through the use of inexpensive adhesives. The operations are carried out in definitely correlated time and space relation with each other so that the coating is applied accurately and economically to a limited portion of the web, avoiding difficulties of securing register and assuring the uniform production in continuous operation of tubular bodies provided with effective and impervious inner surfacings.

While the process and apparatus herein described constitute preferred embodiments of the invention, it is to be understood that the invention is not limited to this precise process and apparatus, and that changes may be made therein without departing from the scope of the in vention which is defined in the appended claims.
