is initially a smooth non wavy material such as for example the mentioned knitted textile and applying it to the carrier 10 with a roller having a sufficiently defined contour that will result in a wavy surface on the structural surface 11 the structural surface 11 is directly laminated onto the carrier 10 while the material is warm and has not yet set the material of the structural surface 10 is actually pressed into the material of the carrier 10 and as the material of the carrier 10 sets the two materials become firmly bonded together the wavy structure of the structural surface 190 has peaks 12 and valleys 14 and these valleys 14 are laminated into the carrier 10 the peaks 14 by contrast are not only not incorporated into the carrier 10 but actually do not necessarily make contact with the carrier 10 because of this loose placement of the peaks 14 they remain freely movable and thus readily deformable to some extent to accommodate a portion of the circumference of the object to the held on the retainer panel 1 fig1 illustrates a retainer panel 1 in which the carrier 10 is made of a three dimensionally contoured thermoforming film ribs 2 are formed in the.
