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.
A dispenser for a supply of continuous strip material, the material having formations that include parting lines spaced at points along the length to define successive units of predetermined length, the parting lines enabling a leading unit to part from the remaining material when the material at the respective parting line is subjected to parting tension, the dispenser comprising
A sheet-form material having first and second sides that carry respective fastener elements, fastener elements on at least the first side comprising a non-woven web of entangled fibers of substantial tenacity having a basis weight of between 1.8 to 2.5 ounces per square yard.
An extended length of fastener material forming a series of detachable strip units suitable for use with a dispenser having a detent, said fastener material having formations that include weakened parting lines at spaced intervals along its length to define the strip units and at least one formation in each strip unit, the formation constructed and arranged to be engaged by said detent to detain the respective unit while a preceding unit is detached by rupture at the parting line by tension applied to the parting line.
A method of forming a composite product having a large multiplicity of hook-form fastener projections extending from the surface of its base portion, the method comprising:
A method of forming a fastener material comprising
