Abstract
In an elongate strip material which can be severed into lengths to form at least a part of a fastener. The strip material comprises a backing and a multiplicity of lengths of polymeric monofilament having cross sections defining a plurality of radially projecting lobes, each length including a central bight portion secured in the backing, and two stem portions extending from opposite ends of the bight portion and projecting away from the backing. Enlarged heads are formed by heat at the ends of the stem portions opposite the backings, and the heads include hook-like portions spaced from the stem portions and projecting along the stem portions toward the backing that result from heating the ends of the monofilaments because of their lobed cross sections.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
