Abstract
A dispenser for strip materials, e.g. hook and loop fastener material, which automatically finds formations in a continuous fastener strip during its dispensing and, at that point in the dispensing procedure, produces a resistance to the remaining supply, that enables parting of the lead unit from the remaining supply, thus dispensing a discrete unit. The dispenser has a receptacle to hold the supply of fastener strip material; it employs a retarding device to provide light drag against the motion of the strip as the leading strip unit moves from the dispenser in response to pull by a user. A detent downstream of the retarding device engages a corresponding formation in the strip material to resist movement of the remaining strip material, so that the strip ruptures along a line of weakness under a user's tension. Also disclosed are dispensable fastener strips of various forms, some advantageously formed by use of needled bat, and methods of forming the fastening strips.
