Definitions

  • the invention relates to an adhesive connection formed by two adhesive fastener parts, in which a first adhesive fastener part is provided on an active side of a film-shaped carrier with a plurality of hooking means protruding from the carrier, which have thickenings at the free ends of flexible stubble, which become during Press on the active side of a second fastener part with the same hooking means provided on it.
  • European patent specification 37 652 discloses an adhesive connection of this type, in which the stubble on each fastener part is arranged at substantially equal distances from one another in each direction and in each direction the number of stubble present on a fastener part per unit length varies from the number of distinguishes stubble present on the other fastener part per unit length and does not form an integral multiple of this number in the other fastener part.
  • the aim of this is to ensure that when shear forces acting parallel to the film-shaped carrier act on the adhesive connection, the two adhesive fastener parts cannot move relative to one another.
  • this effect is in the known fastener parts not reached to the same extent in all places, so that when shear forces occur, the two fastener parts can twist against each other or even shift in some places.
  • the invention has for its object to provide an adhesive connection in which the adhesive fastener parts cannot move against each other when shear forces parallel to the film-shaped carrier occur.
  • the two fastener parts can not move against each other in the two directions mentioned even when shear forces occur. Since shear forces in other directions can be divided into two components that extend in the two directions mentioned, the two adhesive fastener parts can also are not displaced against each other by shear forces which act on the two adhesive fastener parts in the adhesive connection in directions deviating from the first or from the second direction.
  • the distance of the grid lines from one another is at least as large as the sum of the thickness of a stubble of the first closure part and measured in the direction of this distance a thickening of the second closure part.
  • the two directions mentioned form an acute angle with one another.
  • the first direction is perpendicular to the second direction.
  • the thickenings can be shaped differently in plan view.
  • the cross section of the stubble can be shaped differently.
  • the thickenings are round and the diameter of the thickening is approximately twice as large as the diameter of the essentially round cross section of the stubble. Hooking means of this type are known and are also referred to as "mushroom heads".
  • Different shaped adhesive fastener parts can be produced by joining the repeats in different ways. However, it is expedient to arrange the repeats in such a way that the adhesive closure part is in the form of a band and the one, preferably the second, direction extends in the longitudinal direction of the band. Adhesive fastener parts of any length can then be cut off from such a tape, it then being irrelevant whether the interface is currently on a dividing line of two repeats or a repeat cuts through.
  • the centers of the hooking means are arranged at every second crossing point of straight lines forming a grid, which are parallel to two mutually perpendicular directions and whose distances from one another are half as large as the distances from the grid lines of the first fastener part.
  • each hooking means consists of a flexible stubble 13, which protrudes vertically from the film-shaped carrier and carries a mushroom-shaped round thickening 14 at its free end.
  • the stubble 13 is round in cross section and has a diameter of 0.5 mm.
  • the diameter of the thickening 14 arranged coaxially to the stubble 13 is 1 mm.
  • the arrangement of the hooking means 11 in the repeat 10 is based on a grid which consists of two grid lines 15 extending parallel in a first direction, namely in the longitudinal direction of the repeat, and four parallel to one another, in one to the other first direction perpendicular second direction, namely the width direction of the repeat, extending raster line 16 is formed.
  • These six grid lines intersect at eight crossing points 17 and thereby form four angles at each crossing point.
  • At each crossing point 17 only one hooking means 11 is arranged such that each stubble 13 is arranged at an angle and thereby touches the two legs of the angle. As a result, each stubble 13 touches one of the two mutually perpendicular grid lines 15 and 16.
  • each grid line 15 and 16 there is therefore a series of hooking means 11, the stubble 13 of which touch this grid line.
  • the angles at which the hooking means 11 are located are selected such that in each of these rows touching a grid line 15 or 16, the hooking means are alternately on different sides of the grid line 15 or 16 concerned and for each pair of grid lines, for example 15, the stubble 13 touching a grid line 16 are arranged either on the sides facing away from one another or on the sides of the grid line 15 facing each other.
  • FIG. 2 shows the top view of a section of a band in which the hooking means 11 are arranged after the repeat of FIG. 1, two repeats arranged alongside one another in the longitudinal and in the width direction being shown in this exemplary embodiment.
  • an adhesive fastener part formed by a portion of this tape has a much larger number of repeats in both the length and width directions.
  • the width direction of the repeat that is the horizontally extending direction in FIG. 2, as the longitudinal direction of the band, contrary to the impression resulting from FIG. 2.
  • FIG. 4 shows the top view of the active side of a second adhesive fastener part, which forms a particularly good adhesive connection with the first adhesive fastener part.
  • this second adhesive closure part is based on a grid which is formed from two sets of grid lines 25 and 26 which are parallel to one another, which are parallel to two mutually perpendicular directions and whose distances d 'are equal to one another. These distances d 'are half the distances d of the grid lines of the first adhesive fastener part.
  • the hooking means 21 are arranged such that center points 27 of their plan view coincide with the crossing points of the grid lines 25 and 26, with a hooking means 21 being arranged on every grid line 25 and 26 only at every second crossing point.
  • the distance b of the grid lines of the first closure part from each other in both directions is 1.81 mm. This is less than the sum of the double diameter of a stubble of the first adhesive fastener part and the simple diameter of a thickening of the second adhesive fastener part, which together gives 2 mm.
  • any thickening of the second fastener part strikes the stubble of the first fastener part in an attempt to move it in a direction parallel to the two mutually perpendicular grid lines, these directions in which the stubble of the first fastener part stops form for the thickening of the second fastener part, are different with each thickening of the second fastener part.
  • the two fastener parts are thereby secured against movements parallel to the carrier. It is therefore essential that the distances between the grid lines of the first closure part are smaller than the sum of the double thickness, measured in the direction of these distances, of a stubble of the first adhesive closure part and a thickening of the second adhesive closure part.
  • the distance between the grid lines 15 and 16 of the first adhesive fastener part should be at least as large as the sum of the thickness of a stubble 13 of the first adhesive fastener part and a thickening 21 of the second adhesive fastener part measured in the direction of these distances.
