<p>A support for a roller-type load-carrier consisting of a carrier-body (1) and one or several transport rails (2), whereby the carrier-body (1) and transport rails (2) are rigidly connected to one another. The materials from which these two components of the support are made possess a different hardness. The carrier body (1), which has a locating face, or parts of the body, is made of a soft material, i.e. can be more easily deformed under pressure without tension; the transport rails (2) are made of a harder material and are more difficult to deform under pressure, so that the transport rails (2), when subjected to a directed pressure, can with their locating surface (14) oriented towards a stop surface (5) of the pressing tool (arrows 3, 30, 31, 32) be pressed into the carrier body (1) and anchored in it. In accordance with a further embodiment of the invention, the opposed contact surfaces of the two components of the support are smaller before the pressing-in of the transport rails (2) than in the secured position.</p> |
