A stand for assembling leaf-chain webs of transport-technological systems of machines, which is made in the form of a frame, on top from two sides of which molding heads are installed with a drive of axial and rotary motion, drive mechanisms in the form of driving and driven shafts with sprockets for displacing the web for a step, plates with guides of dovetail type, a hydraulic cylinder, moreover on each shaft for example four pairs of sprocket drives are coaxially fastened with distances between them equal to the length of U-shaped bars, and the sprockets are in interaction with special chains, in which evenly, periodically and in staggered order special coupling links are rigidly fixed, from below under the sprockets of driving and driven shafts a horizontal support is installed with area, which is greater than the area of leaf-chain web, on which for example four chains are rigidly fixed, which are in interaction with the sprockets of driving shaft, and dies with elements of fixing rivets of connection of the chain with U-shaped bars are installed on the left downstream of the sprocket drives of driving shaft.
