<p>The support (4) is U shaped (5) and is made in elastic material. Its branches (5a,5b) are inclined towards each other, near their free edges. One branch (5b) has tongues (6,7,8,9,10), projecting from the longitudinal base (5c), which are separated.The strip of fabric has rectangular holes along its upper edge and these fit over the tongues. The bottom of the holes rest on the base of the support, parallel to the edge of the fabric. The outer sides of the branches have longitudinal ribs (11,12) which hold the support in the longitudinal groove of a rail.</p> |
