Abstract: The invention relates to a method of manufacturing a fastener device by extrusion of a thermoplastic material through a shaped drawplate. The extruded strip includes a plurality of rows of longitudinal ribs connected at their bases by legs integral therewith at one end and connected at their edges to two contiguous longitudinally extending flat zones. The ribs are cut throughout their height and then the strip is stretched providing spaced apart ribs and openings in the base of the strip. The tops of the ribs are enlarged and are of greater width than the width of the openings thus providing a plurality of male and female connecting elements on the same strip.

Abstract: A method for producing an article-catching strip consisting in starting from a preferably extruded strip of material provided on at least one side with longitudinal ribs and in cutting across said ribs notches defining between same substantially hook-shaped elements adapted to catch a similar strip or a piece of fabric. The invention covers also the corresponding arrangement which includes an extruding machine, a drum or the like guiding means feeding the ribbed strip to a cutting system beyond which the strip provided with its article-catching elements may be stretched in a drawing frame to more widely space said elements.
