PVC (polyvinyl chloride) is a versatile polymeric plastic.
Many industrial fabric companies use welding technology to
join panels using overlapped or butt seams. In overlap seams, one
sheet of vinyl-coated fabric is welded to another piece, usually of
the same type, by laying one sheet on the other along the intended
joint with anywhere from a one half to three inch wide contact area.
In a butt seam, the two primary sheets are aligned with no overlap
and an additional third piece, a narrow strip of a compatible
fabric, is welded behind the joint. By thus joining sheets of fabric
which are usually woven and coated in sizes no wider than five
meters (about 16 feet), fabricators can build many types of
industrial barriers, tarps and covers, tents and tensile structures,
grand format banners and building wraps, agricultural covers, and
other large structures. Because the polyester webbing inside PVC-coated webbing is essentially the same as regular polyester webbing, PVC-coated webbing can also still be sewn using traditional stitching machinery. This method is used in heavy applications such as reinforcing fold-backs behind tent hardware and in lightweight applications such as for smaller signs and banners where the waterproof characteristics of the PVC-coating may be desired but when welding is impractical. Once sewn, PVC-coated webbing offers the advantage that if can be slightly re-melted with a heat gun to seal needle holes. In small sign shop applications, PVC-coated webbing can also be applied using PVC-specific solvent adhesives or with double-sided banner tape without any welding at all..

It has come to our attention that one company is attempting to corner the market on the term “weldable webbing”. Our position is that the term “weldable webbing” is generic. The term “weldable webbing” was coined by Jim Logan in a previous job. In the ten or more years since the term was first used, it has become a world-wide, generic term used, in several different industries, to describe webbing products that can be molecularly welded to other textile products that have similar coatings. The term is used by producers and sellers of the product everywhere. It is usually used in reference to webbing coated with polyvinyl chloride (PCV) but it is also used to describe webbings coated with other materials such as urethane. Since the term has come into standard usage, there has been no attempt by anyone who uses it to prevent anyone else from doing so. That it because it is clear in the industry that the term has become a generic description for the product and also because no single entity, including the Louis A. Green Corporation, possessed a valid trademark on the term. In fact, no one has ever attempted to apply for a legal trademark on the name until Louis A. Green Corp did so, only in Massachusetts on April 15 of this year (2010), a full ten years after the wording had spread around the world as a generic term. |
Our position is that there has not been any trademark protection for use of the term for over a decade since its first use, and that there should be none now. It is interesting to note that the actual manufacturer of the product that the Louis A. Green Corp distributes, Bowmer Bond Narrow Fabrics Ltd in Ashbourne, England, has never attempted to trademark the term as a name for its own product. The term is now used internationally by dozens of manufacturers and distributors. (Click here to see a partial directory of companies using the term generated by a simple internet search engine.) There should be no doubt that “weldable webbing” has become a worldwide generic term. We hope that this answers any questions users of the products may have. Until we are instructed by a legal ruling, we – along with the rest of the world – will continue to use the expression “weldable webbing” as a generic term describing webbing that can be welded. We welcome any legal challenge to our stance because it will provide a judge the opportunity to disallow any scurrilous or deceptive actions taken by any parties improperly attempting to claim ownership of the words.
