SPIRALLY COILED PAPER TUBING AND METHOD OF MAKING Filed Feb. 12, 1931 Patented Nov. l, 1932 UNITE STATES RALPH P. BURTON, F CHICAGO HEIGHTS, ILLINOIS lSPIR-ALLY COILED PAPER TUBING AND METHOD 0F MAKING Application led February 12, 1931*.
The purpose of this invention is to make spirally coiled paper tubing interiorly liquidproofed and thereby adapted to be used for the bodies of containers for liquid commercial 3 products, particularly those of the character of grease, such as lard, butter, cream and other animal oils and vegetable oils. y
The invention consists in the method and steps in the process of producing such spiral l0 tubing and the tubing produced by this method.
The drawing illustrates parts of the mechanism Which may be utilized in carrying out the method which constitutes the invention.
Figure l is an axial section of.a piece of spirally coiled tubing made in accordance with this invention.

Figure 4 is a detail sectional elevation of a part of Figure 2, section being made as indicated at the line 4-4 on Figure 2 through a part Which is added to the familiar type ceiling machine for the purpose of the method of this invention.
For the best understanding of the invenr tion, the problem of which it becomes a solution, may be first described.
This problem, as indicated, relates to the economical production of a paper container for commercial substances liquid or semiliquid for which the container must be liquidproofed to prevent waste-'of the content by leakage resulting from the liquid content soaking, saturating and penetrating the container Wall.
For preventing such leakage the container must' be at least interiorly rendered liquidproef. Two methods have been attempted and somewhat employed for rendering paper containers of the familiar type having the Serial No. 515,220.
body made from spirally coiled paper tubing, interiorly liquid-proof.
According to the first method, the containers are mechanically completed through the steps'consisting of ceiling the paper strip into a tube, cutting the tube into container lengths, and securing the bottoms to the bodies. In this condition,of open-mouthed cups or cans,-suitable liquid-proofing substance is applied to the interior of the container by s'praying the same With such liquidproofing substance, which requires to be set by drying in order to serve the purpose of rendering the container liquid-proof.
This method is quite unsatlsfactory for tWo reasons: First, it is impossible to avoid the formation of minute air bubbles in the process of spraying the liquid onto the inner surface of the container; and in the next process-of drying to set the liquid-proofing substance,fthese air bubbles are liable to burst, forming minute holes in the otherwise liquid-proof coating through which the liquid or semi-liquid content of the container gets direct access to the paper, and soon soaks through it, forming a leak at each such broken bubble.
Secondly, this method is unsatisfactory, and almost prohibitively expensive for the reason that for drying and setting the liquidproofing substance on the inner surface of the containers, the latter must be stored in a drying chamber exposed to proper drying temperature for about four hours before the liquid-proofing is sufficiently set to permit the completion of the containers by applying the covers and the necessary exterior labels and markings to fit them for the commercial use for Which they are Wanted. And when it is considered that the containers are delivered 9C at the rate of four hundred per minute from the automatic machine by which the spirally coiled tubing is produced and cut into container lengths and by which the bottoms are applied and secured, and from which they c.; are automatically delivered to the spraying apparatus andlthence to the drying chamber through which they must be automatically fed and from which they must be taken automatically after four hours travel through the 10o drying chamber to the labelling and coverapplying mechanism, it will be seen thatthe drying chamber, large enough to accommodate four hours output of the coiling, bottoming, and spraying apparatus, is a necessary part of the-complete mechanism for continuous automatic manufacture of such containers; it may be understood that the cost of accommodating and operating the organization which includes such extended drying apparatus, is prohibitive.
In the second method above referred to,'
avoiding the difficulty arising from the slow drying of the interiorly coated containers, the liquid-proofing material is applied to the paper in the strip in the process of winding it from the original` storage spool onto another spool, the strip on its way from one spool to the other receiving the coating and running thence through a suitably extended passage in which it is exposed to hot air current for drying, which causes the liquid-proofing to be well set when it reaches and is wound onto the second spool; and the second spool being mounted in the spiral coiling machine, the tube is produced by the familiar method of such machines, the inner coiled strip being coiled with its consecutive coils abutting edge to edge, and an outer coil being simultaneously formed lapping the spiral seam between the abutting edges of the inner coil. Thus the completed tube has its inner surface completely covered with the fully dried and set liquid-proofing.
This method has been found unsatisfactory because it is practically impossible to produce the paper strip with its opposite edges so perfectly parallel and perfectly rectilinear that the spiral seam between the abutting edges of the consecutive coils will be perfectly closed; and on the contrary, in the. operation of this method the opportunity -for leakage between the abutting coils is even greater than that experienced from the bursting of n bubbles of the sprayed liquid-proof coatin the `first described method: ne diiculties and defects of both these previously employed methods are avoided in the method which constitutes the present in? vention.
i In the practice of this method there is rst produced a thin paper strip liquidproofed in the manner above described'for liquid-proofing the inner coiled strip in the second above described method. This thin liquid-proofed paper strip is used as a lining for the inner/coil of the tubing and lis made a little wider than the strip which is to form the inner coil. The two strips are fed together into the coiling mandrel with the inner Wider strip next to the mandrel, and with marginal portions of .the excess width of the liquid-proofed lining strip projecting past the opposite edges of the narrower strip. Suitable adhesive is applied between the two strips in their course from the spools to the mandrel.
The marginally projectin portion of the lining strip at the edge o the two strips whose course onto the mandrel is at an acute angle to the latter, is guided for defiecting it slightly out of the plane of the contacting surfaces of the two strips and away from the axis of the mandrel just before the strips run onto the mandrel, with the effect of causing said marginal portion to be completely folded about the edge of the narrower heavier strip in the spiral advance of the strips around the mandrel. The marginal portion of the liquid-proofed lining strip at the edge of the strips, whose course onto the mandrel makes an obtuse angle with the mandrel, is permitted to take its normal course onto the mandrel and thereby becomes laid on the outer sul'- face of a marginal portion of the immediately preceding coil, and thus is fiexed past and between the abutting edges of the two coils; and in the further movement of the two coils over the convex surface of the mandrel, said marginal portion, now lapped outside the next preceding coil, and over the edge about which the first mentioned marginal portion has been folded, tends to be drawn snugly down uponthe outer surface of said next preceding coil; and by this means there is interposed in the spiral seam between the successive coils a completely liquid-proofed element which, lapping outside the one coil and inside the other coil, effects a complete and completely liquid-proofed sealing of the spiral seam throughout the entire extent of the tubing.
The customary outer coil wound vonto the mandrel simultaneously with the inner coil and its lining strip, and, as in the customary manner of producing spirally coiled paper tubing,-arranged lapping the spiral seam of the inner coil, operates to ensure the com plete sealing of the spiral seam of the inner coil by the liquid-proofed lining strip applied in the manner described.
Referring to the mechanism shown in the drawing for practicing the method above described, the customary construction of this mechanism comprises a frame partly indicated at A, a mandrel, B, mounted iixedly at one end of the frame, and having the other cnd,-the right hand end in Figure 2,-extending free, a pair of endless feeding belts. D, C, passing around driving pulleys, D1, and intermediate said driving pulleys at one side of their endless courses respectively making each a spiral turn about the mandrel for engaging the spirally wound tubing for feeding the paper strips by which it'is formed. 'i
is to constitute the liquid-proofed linin of the tube as described, and a third spool not shown) carries a paper strip, H, to constitute the outer coil ofthe paper tubing lapping the spiral seam of the inner coll.
All the parts of the mechanism as thus far described are of familiar form and construction, and the feeding belt is arranged to be operated by suitable means, not shown, for rotating the pulleys, D1.
The means for initially deflecting the marginally projecting portion of the lining strip first mentioned for causing said mar inal portion to be folded about the edge o the strip, F, as shown, consists of a slender roller, K, carried on a spindle,vK1, which may be understood to be suitably mounted on the frame for positioning said roller, as shown in Figures 2,3 and 4 extending tangentially with respect to the mandrel past the edge of the strip, F, which runs onto the mandrel at an acute angle thereto, for initially flexing the marginal portion of the strip F at that edge past the edge of the strip, G, that is, outwardly with respectl to the mandrel to cause said marginal portion to become folded fully as a binding about the edge of the strip, G, as the strips pass around the mandrel with that marginal portion at the outer side of the strip, G.
