Abstract
Abstract The raw metal edge on the inside lap in an adhesively-bonded lap side seam of a tubular body is protected from chemical attack by a corrosive substance from within the tubular body by applying a side seam adhesive along one marginal edge portion of the body blank, bending the other parallel marginal edge portion of the blank to form a crease thereon, rolling the blank into tubular form to place the adhesively-coated marginal edge portion and the creased marginal edge portion in an overlapping, facing position, and imbedding the creased marginal edge portion into a portion of the adhesive on the one marginal edge portion to bury the raw metal edge, the imbedding being achieved by compressing the overlapped marginal edge portions together to assemble the lap side seam of the tubular body.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
166 words
A method of providing a crease on the inside lap in an adhesively-bonded lap side seam of a tubular body, comprising the steps of: applying a side seam adhesive along one marginal edge portion of a body blank; bending the other marginal edge portion of the body blank in a single direction to form a crease thereon which points toward the adhesive on the one marginal edge portion when the blank is formed into tubular form; forming the body blank into tubular form in order to overlap the creased marginal edge portion with the one marginal edge portion so that the creased marginal edge is the inside lap and so that the crease points toward and is proximate to the adhesive on the one marginal edge portion; and imbedding the creased marginal edge portion into a portion of the side seam adhesive on the one marginal edge portion by compressing the overlapped marginal edge portions together to assemble the lap side seam of the tubular body.
Claim 2
Independent Claim
166 words
A method of providing a crease on the inside lap in an adhesively-bonded lap side seam of a tubular body, comprising the steps of: applying a side seam adhesive along one marginal edge portion of a body blank; bending the other marginal edge portion of the body blank in a single direction to form a crease thereon which points toward the adhesive on the one marginal edge portion when the blank is formed into tubular form; forming the body blank into tubular form in order to overlap the creased marginal edge portion with the one marginal edge portion so that the creased marginal edge is the inside lap and so that the crease points toward and is proximate to the adhesive on the one marginal edge portion; and imbedding the creased marginal edge portion into a portion of the side seam adhesive on the one marginal edge portion by compressing the overlapped marginal edge portions together to assemble the lap side seam of the tubular body.
Claim 3
Independent Claim
183 words
A method of providing a crease on the inside lap in an adhesively-bonded lap side seam of a tubular body, comprising the steps of: applying a side seam adhesive along one marginal edge portion of a body blank; bending the other marginal edge portion of the body blank in a single direction toward the surface of the body blank which is opposite the surface on which the side seam adhesive is applied, to form a crease thereon; forming the body blank into tubular form in order to place the other marginal edge portion with the crease thereon and the one marginal edge portion with the side seam adhesive thereon in a slightly offset overlapping, facing position, said other marginal edge portion forming the inside lap and said crease pointing toward and being proximate to the adhesive on said one marginal edge portion; and imbedding the other creased marginal edge portion into a portion of the side seam adhesive on the one marginal edge portion by compressing the overlapped, facing marginal edge portions together to assemble the lap side seam of the tubular body.

Independent Claim
192 words
A method of joining the opposed longitudinal marginal edge protions of a body blank to form the longitudinally extending lap side seam of a tubular body and simultaneously therewith protecting the raw metal edge on the inside marginal lap edge portion from chemical attack by a corrosive substance within the tubular body, comprising the steps of: applying a side seam adhesive along one marginal edge portion of a body blank; bending the other marginal edge portion of the body blank in a single direction to form a crease thereon; forming the body blank into tubular form in order to overlap the creased marginal edge portion with the one marginal edge portion; so tHat the creased marginal edge is the inside lap and so that the crease points toward and is proximate to the adhesive on the one marginal edge portion; and imbedding the creased marginal edge portion into a portion of the side seam adhesive on the one marginal edge portion by compressing the overlapped marginal edge portions together to assemble the lap side seam of the tubular body; and applying a side seam stripe to the inside lap side seam surface.
Claim 6
Independent Claim
192 words
A method of joining the opposed longitudinal marginal edge protions of a body blank to form the longitudinally extending lap side seam of a tubular body and simultaneously therewith protecting the raw metal edge on the inside marginal lap edge portion from chemical attack by a corrosive substance within the tubular body, comprising the steps of: applying a side seam adhesive along one marginal edge portion of a body blank; bending the other marginal edge portion of the body blank in a single direction to form a crease thereon; forming the body blank into tubular form in order to overlap the creased marginal edge portion with the one marginal edge portion; so tHat the creased marginal edge is the inside lap and so that the crease points toward and is proximate to the adhesive on the one marginal edge portion; and imbedding the creased marginal edge portion into a portion of the side seam adhesive on the one marginal edge portion by compressing the overlapped marginal edge portions together to assemble the lap side seam of the tubular body; and applying a side seam stripe to the inside lap side seam surface.
