Abstract
Abstract An elongated article is wrapped by forming thereon a winding of a strip of a flexible wrapping material (12) which has a first face (13) carrying first and second portions (13a, 13b) of a coating of an adhesive substance of a per se known kind which without the application of heat adheres strongly only to itself, the second face (15) being free from such adhesive substance, and by turning over a longitudinal edge portion of the strip which includes said first portion (13a) of the coating, as the strip is wound around the article, so as to bring it into face-to-face with the second portion (13b) of the coating on a previously formed turn of the winding.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
207 words
A method of wrapping an elongate article by forming a winding of at least one strip of flexible wrapping material helically around said article so that successive turns of the wrapping overlap one another, characterized by the use of a strip of wrapping material wherein a first face of the strip carries first and second portions of a coating of an adhesive substance of a per se known kind which without the application of heat adheres strongly only to itself and wherein a second face of the strip is free from said adhesive material, and by the steps of turning over a longitudinal edge portion of said strip which includes said first portion of the coating so as to fold the second face of the strip onto itself, and laying the folded strip onto the article with the second portion of the coating on each turn of the winding in contact with the first portion of said coating on an adjacent turn of the winding while said second portion of said coating on said first face of the strip is directed away from the article being wrapped and said longitudinal edge portion is turned inwardly, said first portion of the coating facing towards the article being wrapped.
Claim 2
Independent Claim
207 words
A method of wrapping an elongate article by forming a winding of at least one strip of flexible wrapping material helically around said article so that successive turns of the wrapping overlap one another, characterized by the use of a strip of wrapping material wherein a first face of the strip carries first and second portions of a coating of an adhesive substance of a per se known kind which without the application of heat adheres strongly only to itself and wherein a second face of the strip is free from said adhesive material, and by the steps of turning over a longitudinal edge portion of said strip which includes said first portion of the coating so as to fold the second face of the strip onto itself, and laying the folded strip onto the article with the second portion of the coating on each turn of the winding in contact with the first portion of said coating on an adjacent turn of the winding while said second portion of said coating on said first face of the strip is directed away from the article being wrapped and said longitudinal edge portion is turned inwardly, said first portion of the coating facing towards the article being wrapped.
Claim 3
Dependent Claim
18 words
A method according to claim 1 wherein said first and second portions of the adhesive coating are contiguous.
Claim 4
Dependent Claim
20 words
A method according to claim 2 wherein said adhesive coating extends across substantially the entire width of said first face.
Claim 5
Dependent Claim
25 words
A method according to claim 1 wherein said first and second portions of the adhesive coating are spaced apart across the width of said strip.
Claim 6
Dependent Claim
20 words
A method according to claim 1 wherein said adhesive substance is substantially nonadherent to said second face of said strip.
Claim 7
Dependent Claim
18 words
A method according to claim 5 wherein said adhesive substance is substantially nonadherent to the article being wrapped.
Claim 8
Dependent Claim
18 words
A method according to claim 1 wherein said adhesive substance is substantially nonadherent to the article being wrapped.
Claim 9
Independent Claim
188 words
A method of wrapping an elongate article by forming a winding of at least one strip of flexible wrapping material helically around said article so that successive turns of the wrapping overlap one another, characterized by the use of a strip of wrapping material wherein a first face of the strip carries first and second portions of a coating of an adhesive substance of a per se known kind which without the application of heat adheres strongly only to itself and wherein a second face of the strip is free from said adhesive material, and wherein said adhesive substance is substantially non-adherent to said second face of said strip and substantially non-adherent to the article being wrapped, and by the steps of turning over a longitudinal edge portion of said strip which includes said first portion of the coating so as to fold the second face of the strip onto itself, and laying the folded strip onto the article with the second portion of said coating on each turn of the winding in contact with the first portion of said coating on an adjacent turn of the winding.
Claim 10
Independent Claim
188 words
A method of wrapping an elongate article by forming a winding of at least one strip of flexible wrapping material helically around said article so that successive turns of the wrapping overlap one another, characterized by the use of a strip of wrapping material wherein a first face of the strip carries first and second portions of a coating of an adhesive substance of a per se known kind which without the application of heat adheres strongly only to itself and wherein a second face of the strip is free from said adhesive material, and wherein said adhesive substance is substantially non-adherent to said second face of said strip and substantially non-adherent to the article being wrapped, and by the steps of turning over a longitudinal edge portion of said strip which includes said first portion of the coating so as to fold the second face of the strip onto itself, and laying the folded strip onto the article with the second portion of said coating on each turn of the winding in contact with the first portion of said coating on an adjacent turn of the winding.
Claim 11
Independent Claim
178 words
A method of wrapping an elongate article by forming a winding of at least one strip of flexible wrapping material helically around said article so that successive turns of the wrapping overlap one another, characterized by the use of a strip of wrapping material wherein a first face of the strip carries first and second portions of a coating of an adhesive substance of a per se known kind which without the application of heat adheres strongly only to itself and wherein a second face of the strip is free from said adhesive material, and wherein said adhesive substance is substantially non-adherent to the article being wrapped, and by the steps of turning over a longitudinal edge portion of said strip which includes said first portion of the coating so as to fold the second face of the strip onto itself, and laying the folded strip onto the article with the second portion of the coating on each turn of the winding in contact with the first portion of said coating on an adjacent turn of the winding.
