The present invention relates to an apparatus and a method for supporting tubes in extrusion lines, with a tube support mechanism that is adaptable to a respective tube diameter that is to be supported, and that is provided with an articulated link chain which rests against at least part of a circumference of the tube, and the chain links of which have end faces directed toward the tube. The object of the invention is to make available a further apparatus as well as a method of this type for adjusting a tube support mechanism. This object is realized in that the articulated link chain (15) is comprised of chain links (17) that are disposed in at least two planes and that overlap one another from plane to plane, wherein the chain links are pivotably connected to one another in the overlap zones, whereby the chain links (17) of each plane have at their facing ends identical gear wheel contours (30) that mesh with one another. The object is furthermore realized in that the adjustment of the tube support mechanism (14) is effected, from one nominal diameter to another nominal diameter, by the pressure effect, onto the tube support mechanism (14), of the conical tube transition piece (5.1) that results during a change in diameter as operation continues, whereby the angle of contact of the tube support mechanism (14) against the tube that is to be supported successively changes.
