HERBERT S. WILSON, OF ST. LOUIS, MISSOURI.
PROCESS OF FORMING PAPER RECEPTACLES.
Application filed March 14, 1910. Serial N 0. 549,199.
To all whom it may concern:
Be it known that I, HERBERT S. WILSON, a citizen of the United States, residing at the city of St. Louis, Missouri, have invented a certain new and useful Process of Forming Paper Receptacles, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to'the accompanying drawings, forming part of this specification.
My invention relates to a process for forming paper receptacles and more particularly for forming water-proof recep. tacles for containing liquids and the like. Such water-proof receptacles are usually formed by coating the paper with melted paraffin. One difliculty in forming tubes from such paper is that the parafiin is not adhesive until it begins to harden and consequently there is great difiiculty experiended in retaining the paper in cylindrical form while the paraflin is hardening.
The object of my invention is to overcome the above difiiculty and this I do by curling one end of the sheet of paper from which the tube or cylinder is to be formed and then rolling the paper into form with the uncurled end inside of the curled end so that the tendency of the inner part of the tube to expand and the outer part to contract firmly holds the layers of paper together while the coating hardens.
In the accompanying drawings which illustrate one form'of apparatus for carrying out my invention, Figure 1 is a diagrammatic view; Fig. 2 is a view of some of the parts shown in Fig. 1 but in different position; Fig. 3 is a diagrammatic vievs of one of the sheets of paper after being curled; Fig. 4 is a side elevation of the completed receptacles partly in section, and Fig. 5 is a diagrammatic view'of apparatus for securing the caps in the receptacle.
10 represents the roll of paper. The strip of paper passes from the roll 10 between the pair of rolls-11 and 12 respectively. The roll 12 may be provided with suitable printing characters to print any suitable matter upon the paper. After the strip of paper passes from the- rolls 11 and 12 it is cut into suitable lengths by means of a pair of knives 13. From the knives 13 the strip of paper passes to feeding rolls 14. It will be understood that the web of paper is carried for- Speciflcation of Letters Patent.

' ward by conveyers which are not shown as the form no part of the present invention an are full referred to elow.. Beyond these feedin rolls 14 are a second pair of rolls 15. Arranged between the rolls 14 and 15 is a spring blade 16 and a pivoted blade 17 having a sharp edge. During the passage of the first part of the strip of paper between the rolls 14 and 15 the pivoted blade 17 is in the position shown in Fig. 2 so that'the first part of the paper'is uncurled. When, however, about one-half of the paper-has passed beyond the spring blade 16, the blade 17 is moved-into the positionshown in Fig. 1 so that the remainder of the paper is drawn across the sharp edge of the blade 17 and caused to curl. The stri of paper after this is accomplished, if le t to itself,'would assume the formshown in Fig. 3, the first half 18 of the paper being uncurled as shown in said figure and the last half 19 curled.
After passing from the rolls 15 the paper passes under a roll 20 so as to immerse the paper 111:3. bath 21 of any suitable material for holdlng the layers of paper together and also preferably water-proofing the paper at p the same time. I prefer to use melted parafiin for this purpose.
ofpaper passes between a pair of rolls 22 and thence to the mandrel 23 upon which it is wound to form a cylinder or tube. Rolls 24 serve '0 press the paper firmly against the mandrel. A guard 25 also preferably partially surrounds the mandrel 23. As the uncurled end 18 of the strip of paper is fed first to the mandrel 23this end of the paper will be rolled inside of the curled end 19. The uncurled. end 18 of the paper will tend to expand while the curled end 19 will tend to contract and as the uncurled end is rolled inslde of the curled end the contrary tendency of movement of the two parts will hold described in my application .85 After passing out of the bath 21 the strip the layers of paper firmly in position while of the bath 28 and fans 30 are pre erably supplied for cooling;
the receptacles 26 and thus hastening the ardening of the melted In other words, the discharged tube retains (during the setting of the adhesive) the form and diameterg-iven to it by the mandrel because of the initial curling of the paper which prevents its unwinding.
The apparatus which I prefer to use in carrying out my invention is shown in detail in application Serial No. 522,350, filed by me Oct. 11, 1909. While I prefer touse such apparatus I do not-wish to be understood as limiting myself to the use of any particular form of apparatus for carrying out my invention.
. Having fully described my invention, what I claim as new and desireto secure by Letters Patent of the United States is:
1. The process of forming a laminated paper tube moisture-proof throughout substantially its entire thickness, which consists in preliminarily giving a strip of paper a tendency to curl up in a plurality of concentric convolutions, then applying thereto a coating of moisture-proof'adhesive, then winding said coated paper strip intotubular laminated form on a cylindrical mandrel,
and then removing the tube from said mandrel before the adhesive has had an opportunity to set, the tendency of the paper to curl'up' after removal of the tube from the mandrel and during .the setting of the adhesive causing the laminations of the tube to hug one another and the tubeto maintain the form and diameter given to it by the mandrel, substantially as described.
2. The process of forming a laminated paper tube which consists in preliminarily giving 'a strip of paper a tendency to curl up in a plurality of concentric convolutions, then-applying thereto an adhesive coating, then winding said coated strip into tubular laminated form on .a cylindrical mandrel, and then removin the tube from said mandrel before the a hesive has had an opportunity to set, the tendency of the paper to curl up after removal of the tube from the mandrel and during the setting of the adhesive causing the laminations of the tube to hug one another and the tube to maintain the form and diameter given to it by the mandrel, substantially as described.
3. The process of forming a moistureproof laminated paper tube, which consists 1n curling a strip of paper to give a portion of the same a more acute curvature than that of the remainder of the strip, applying a moisture-proof adhesive to said strip, and
then winding the strip into tubular form with the portion of sharper curvature outermost whereby the convolutions are held together in position during the setting of the adhesive which secures them together, substantially as described.
4. The process of forming ,a laminated expand and the outer convolutions to contract, substantially as described.
5. The process of forming a laminated paper tube, which consists in curling a portion only of a strip of paper, applying an adhesive to said strip, and Winding the strip into tubular form with the uncurled portion innermost, whereby the convolutions are held together in position during the setting .of the adhesive securing them together by the tendency of the inner convolutions to expand and the outer convolutions tocontract, substantially as described.
