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.
