Definitions

  • ABSTRACT The raw metal edge of the inside lap of an adhesively bonded lap side-seam of a tubular bodyis coated and protected from chemical attack by a corrosive substance contained within the tubular body by applying a ribbon of side seam adhesive along one marginal edge portion of the body blank, the ribbon having a fillet thereon located along its inner edge, forming the blank into tubular form, bringing the marginal portions together in an overlapping opposing relation, and pressing the marginal portions together to assemble the lap side seam in a manner such that the raw metal edge of the inside lap is pressed into a portion of the fillet and is overlapped, coated and thereby protected by thatportion of the fillet.
  • each overlapped marginal edge usually terminates in raw metal edge.
  • the outer surface of the tubular body and the raw edge of the outer lap can readily be protected against various forms of chemical attack by the application thereover of one or more suitable protective coatings.
  • tubular body is a container used to package particularly corrosive substances such as a carbonated beverage.
  • the present invention is concerned with a novel method and apparatus for coating the raw metal edge on the inside lap in an adhesively bonded lap side seam of a tubular body, during the assembly of the lap side seam.
  • the advantage or benefit, therefor, to be gained by treating the raw metal edge with a coating is the protection of the raw metal edge on the inside lap from chemical attack by a corrosive substance within the tubular body.
  • This raw metal edge treatment is especially valuable in making adhesively bonded lap side seam container bodies suitable for carbonated beverages.
  • the advantage in treating the raw metal edge on the inside lap is in the substantial reduction of iron pickup by a corrosive carbonated beverage which will ultimately be packaged within the container. Whereas heretofore iron pickup values were inconsistent and often as high as 3 ppm, under this invention, iron pickup values are consistently below 1 ppm.
  • This invention relates to a method and apparatus for coating and protecting the raw metal edge of the inside lap of an adhesively bonded lap side seam of a tubular body.
  • a ribbon of side seam adhesive is applied along one marginal portion of a body blank, the ribbon having a fillet thereon adjacent to and along the length of its inside edge.
  • the body blank is then made into tubular form to adjacently overlap one marginal portion with an opposite marginal edge portion. When this is done the overlapped marginal portions are pressed together to form the lap side seam.
  • FIG. 1 is a schematic view in perspective illustrating the method and apparatus of the present invention.
  • FIG. 2 is an enlarged sectional view of an extruder die orifice taken substantially along lines 2-2 of FIG. 1.
  • FIG. 3 is an enlarged fragmentary side view taken substantially along line 3-3 of FIG. 1..
  • FIG. 4 is an enlarged fragmentary sectional view of the overlapped marginal portions of a tubular body before an adhesively bonded lap side seam is formed.
  • FIG. 5 is an enlarged fragmentary sectional view of an adhesively bonded lap side seam formed with the marginal portions of FIG. 4.
  • FIG. 1 shows a sequence of operations for forming a substantially rectangular body blank, generally designated 10 into an open ended tubular body generally designated 12, wherein such sequence of operations, novel steps are provided which will be described hereinafter.
  • tubular as used herein is meant to denote elliptical, rectangular or polygonal cross sectional-shaped as well as circular.
  • a body blank 10 is moved along a path of travel from left to right by any suitable means, such as a conveyor as shown in the aforementioned U.S. Pat. No. 3,481,809.
  • a first step marginal portion 14, also called a marginal edge portion, adjacent its side edge 16, can be heated by heating means such as radiant heat elements 18.
  • body blank 10 is conveyed along the path of travel to where its side edges 16 and 17 are engaged by gauging means such as guiding rollers 20 (only a few shown) which guide the blanks into a desired position as will be explained later.
  • heated marginal edge portion 14 passes between upwardly positioned applicator means which can include an applicator wheel 22 and extruder die 24, and an underlyingly positioned back-up roller 26.
  • Extruder 24 can continuously extrude at a substantially uniform linear rate a ribbon 28 of a suitable organic cement or adhesive which is directed into contact with surface 21 of a preferably bon 28 is extruded onto applicator wheel 22, fillet 29 is aligned or registered with an annular groove 23 in the applicator wheel 22. This preserves the shape of fillet 29.
  • Fillet 29 of ribbon 28 can be so aligned and can be applied to the same desired marginal edge portion 14 of each body blank because guiding rollers 20 bring the respective side edges and marginal portions of the blanks into linear alignment with each other and with respective groove 23 and 32 of applicator wheel 22 and ironing roller 30.
  • ribbon 28 can be brought into'contact with and applied to any predetermined portion of heated marginal edge portion 14, preferably, the outer edge of ribbon 28 is removed up to 0.015 inch from side edge 16. This prevents adhesive material from extending over side edge 16 and from appearin on the outside of the tubular body.
  • ribbon 28 is extruded from extruder 24 at a linear rate less than the peripheral speed of surface 21 of rotating applicator wheel 22 so that a stretching force is exerted on the intermediary free portion of the ribbon 28.
  • This stretching force or tension uniformly decreases the width and cross section of the ribbon and eliminate irregularities therein due to the extruding process.
  • This slight stretching maintains a slight tension on that portion of the ribbon and thereby minimizes the possibility of the ribbon shifting transversely on surface 21 of applicator wheel 22 and on the marginal edge portion 14 of body blank 10.
  • the amount of stretching can be controled by adjusting applicator wheel speed and by changing the distance between extruder 24 and wheel 22. 1
  • Body blank 10 is next conveyed further along its path of travel, to pass marginal edge portion 14 of blank 10 having adhesive ribbon 28 thereon between ironing means which can comprise pinch rolls such as ironing roll 30 and back-up roll 34. Passing the ribbon between such rolls aids in the obtaining of additional adhesion of ribbon 28 to marginal edge portion 14.
  • lroning roll 30 preferably is chilled and has an annular groove 32 therein aligned. or registered with fillet 29, so that its shape is not ironed out or substantially effected by ironing roll 30.
  • applicator wheel 22 and ironing roll 30 are chilled so that ribbon 28 will be pulled away from and properly transferred to body blank 10 by the forces exerted on ribbon 28 by heated marginal edge portion 14 of body blank 10.
  • marginal edge portion 14 having adhesive ribbon 28 thereon can pass through conventional cooling means (not shown) to cool the material and render it relatively solid and self supporting so that the ribbon can then be severed at a free interconnecting portion thereof to produce individual separated body blanks.
  • cooling means not shown
  • This can be accomplished by means such as a cutter wheel 36 having cut.- ting means such as cutter 38 thereon and timed to rotate faster than the speed of passing body blanks so that cutter 38 severs interstitial free portions of ribbon 28 I without contacting the blanks.
  • body blank 10 can be moved to a conventional notching station (not shown) to provide notched corners therein which facilitate formation of the lap side seam.
  • Body blank 10 is then formed into an open ended tubular body 12 by any suitable means, for example on a high-speed automatic, can bodymaker by wrapping the blank around a mandrel, heating the side seam adhesive to a semi-fiuid, tacky condition and compressing the overlapped marginal edge portions into intimate contact with the tacky "side seam adhesive. Immediately thereafter the adhesively bonded lap side seam is chilled to set the adhesive and to secure the lapped marginal edge portions together. Details of a particular bodymaker and other means which may be used in carrying out the above described operations are shown in U.S. Pat. No. 1,625,091 issued on Apr. 17, 1927 and U.S. Pat. No. 3,508,507 issued on Apr. 28, 1970.
  • body blank 10 is rolled clockwise through a l80 path into tubular body 12 to place marginal edge portion 14 having the side seam adhesive ribbon 28 thereon and marginal edge portion 15 in overlapping facing positions (as shown in greater detail in FIG. 4). ln such position, the outside surface of marginal edge portion 14 is heated by heating means such as burners 39 to render adhesive ribbon 28 tacky.
  • Marginal edge portion 14 becomes the outside lap 14 and marginal edge portion 15 now becomes the inside lap 15 (See FIG. 4) which will subsequently be adhesively bonded into a lap side seam (See FIG. 5).
  • Compressing means comprising an upper spline means 44 and a lower hammer means 45, then bring the inside lap 15 into contact with side seam adhesive ribbon 28 on the inside surface of the outside lap 14 to thereby assemble and form the lap side seam 40 (See FIG. 5) of tubular body 12.
  • compressing means 42 brings inside lap 15 down into engagement with a portion of fillet 29 so that raw metal edge 17 is abuttingly overlapped, coated and thereby protected by the engaging portion of fillet 29.
  • FIG. 2 is an enlarged sectional top view taken through extruder die 24 showing a ribbon-shaped orifice generally designated 46 and having a notched fillet orifice'48 therein.
  • Orifice 46 is shaped larger than the size of ribbon 28' as it appears on body blank 10 because, as previously indicated, the counterclockwise rotation of applicator wheel 22 applies stretching force or tension upon ribbon 28 which pulls it out of the extruder and reducing its width and cross sectional dimensions.
  • Notched orifice 48 has a slightly upwardly angled upper surface which coincides with that of fillet 29.
  • FIG. 3 is an enlarged cross section taken through applicator wheel 22 showing a portion of ribbon 28 and its fillet 29 being applied'to the marginal edge portion 14 of body blank whose lower surface is in abutting engagement with back-up roller 26.
  • FIG. 3 shows that the planar width of ribbon 28 is narrower at the point of application shown in FIG. 3 than at the point of origin at orifice 46 of FIG. 2.
  • FIG. 3 also shows that surface 21 of applicator wheel 22 is but need not be serrated with small annular ridges 50 and channels 51 therein which aid in preventing ribbon-28 from shifting transversely on surface 21 of applicator wheel 22.
  • FIG. 4 is an enlarged fragmentary sectional view showing marginal edge of the inside lap in overlapping adjacent opposing relationship with'outer lap marginal edge portion 14 which has on its inner surface ribbon 28 inwardly offset from side edge 16.
  • Marginal edge portions 15 and 14 can each have an interior organic coating 54 and an exterior coating 56 on their respective interior and exterior surfaces.
  • FIG. 4 also shows angled upper surface of fillet 29 as imparted by notched fillet orifice 48 and as maintained by respec' tive grooves 23 and 32 of applicator wheel 22 and ironing roll 30, and it shows small annular peaks 52 andvalleys 53 in the wider planar portion of ribbon 28 as imparted by serrated surface 21 of applicator wheel 22.
  • F 10. 5 is an enlarged fragmentary sectional view of Q the overlapped side seam after the marginal edge portions 15 and 14 have been compressed by compressing means 42 of FIG. 1.
  • Marginal portion 15 is compressed into a portion of fillet 29 in a manner such that its side edge 17 is embedded into and is -abuttingly overlapped, coated and thereby protected by that portion of fillet 29. It is significant to note that only a small portion of fillet 29 overlaps a short length of marginal portion 15 which is parallel to the inside surface of marginal edge portion 14.
  • the offset between the outer lap side edge 16 and the edge of ribbon 28 is not appreciably effected although part of the material in fillet 29 is often moved leftwardly.
  • the side seam adhesive utilized as ribbon 28 can be any suitable conventional organic cement or adhesive known in the art, preferably the adhesive is a high strength superpolyamide generally characterized by having an intrinsic viscosity of at least 0.4, and by having recurring aliphatic amido groups separated by alkylene groups having at least two carbon atoms. These superpolyamides and the definition of intrinsic viscosity are disclosed in US. Pat. No. 2,130,948.
  • superpolyamides which are useful in the present invention are polypentamethylene sebacamide, polyhexamethylene adipamide, polyhexamethylene sebacamide, polydecamethylene adipamide, polydecamethylene sebacamide, poly-m-phenylene sebacamide, 6-amino-caprioic acid polymers, 7-amino-heptanoic acid polymers, 1 l-amino undecanoic acid polymers and l2-amino-stearic acid polymers, with poly-1 1 amino undecanoic being preferred.
  • side seam adhesive ribbon 28 is not usually applied directly to the interior and exterior body surfaces of body blank 10 but rather to respective surface coatings 54 on the interior surface of marginal portion 14, and to the exterior surface coating 56 applied thereover.
  • coatings 54 and 56 can be any suitable organic coating used in the art, it has been found that very strong lap side seams with high burst resistance strength especially advantageous for containers of carbonated beverages, can be obtained when ribbon 28 is the aforementioned preferred linear superpolyamide and it is applied directly to interior and exterior coatings 54 and 56 which preferably contain a 1,2-epoxide resin having before curing an epoxide equivalent of from 425 to 6000 and a number average molecular weight from 1 ,000 to 4,000.
