DESCRIPTION:
BRIEF SUMMARY
DESCRIPTION OF THE INVENTION
This invention relates generally to any package formed by wrapping articles by strips or narrow widths of material wrapped around those articles and in particular to a method of wrapping elongate articles, such as pipes, rods, tubes and other elements, which may be substantially straight throughout their length, or of curved or other non-linear form, or even in the form of a closed loop, such elements being wrapped either singly or in bundles, and the term "elongate article" as used herein is intended to encompass all such elements either singly or in bundles. The invention also relates to a package comprising an elongate article, as above defined, provided with a wrapping in accordance with the method hereinafter described.
Conventionally, such articles are wrapped by means of one or more strips of paper or the like which are wound helically around them using appropriate machinery, for example as shown in German Patent Specification No. 2256708, so that adjacent windings overlap somewhat and may be adhesively secured together where they overlap, although not necessarily.
A preferred method of wrapping is described in our European Patent Specification No.0388795 whereby the strip of wrapping material is coated on one side only with an adhesive of a kind (usually known as a "cold seal" adhesive) which without the application of heat adheres strongly only to itself, and a longitudinal edge portion of the strip is turned over in such a manner that as the strip is wound around the elongate article being wrapped thereby, that portion of the adhesive coating which is carried by the turned over portion of the strip engages a remaining portion of the adhesive coating carried by a non-turned over portion of the strip on an adjacent turn of the winding.
In order to open the package formed by either of the above methods, it is necessary to cut or rip the wrapping material along substantially the entire length of the wrapped article. However, the use of a cutting tool may damage the wrapped article and although specially designed cutters have been provided which are intended to prevent damage to the wrapped article, these are often lost so that any cutting implement at hand may be used with attendant risk of damage to the wrapped article. Ripping the wrapping material may be difficult and unacceptably slow, and also is not without risk of damage to the wrapped article, at least in some cases.
Accordingly, it is an object of the present invention to provide an improved method of wrapping, particularly elongate articles to facilitate the unwrapping thereof when required.
According to the present invention we provide a method of wrapping an article by forming a winding thereon of at least one strip of flexible wrapping material wound helically around said article so that successive turns of the wrapping material overlap one another, characterised by the step of laying between the wrapping material and the article a longitudinally extending tear member which extends over substantially the entire length of the article with an end portion of the tear member exposed externally of the wrapping and thereby available to be pulled in a direction away from the article so as thereby to tear through the successive turns of the wrapping material and along substantially the entire length of the article.
The invention also resides in a package comprising an article having thereon a wrapping comprising at least one strip of wrapping material wound helically around the article in such a manner that successive turns of the wrapping material overlap one another and are adhesively secured together where they overlap, characterised by a tear member which extends over substantially the entire length of the article with an end portion of the tear member exposed externally of the wrapping and thereby available to be pulled in a direction away from the article so as thereby to tear through the successive turns of the wrapping material and along substantially the entire length of the article.
Preferably, the tear me
