ML 301/G-500 - Jigs for assembling and welding bicycle frames. Quite simple and extremely sturdy jigs have been studied to assemble and weld bicycle frames with all possible geometrical dimensions without moving the frame from the jig. These units are indispensable for designers of both custom made frames and prototypes and necessary for manufacturers of standard frames since they enable to quite easily pass from the smallest to the biggest of frames. Dimensions and angles are easy to set; just a few data are necessary and the jig provides for the remaining ones with the possibility of storing dimensions and tube lengths on a proper chart for an easier repetition of the same frame production. A unique detail of jigs ML 301/G is the fact that they not only have the distance of 500mm. between the frame centerline and the base plate, but that they also rotate 360 degrees around a horizontal axle, wherefore the operator has access to all frame points, even the ones that are quite difficult to weld. The jigs are provided with a pneumatically controlled brake to stop the jig in any optimal position while it rotates. The most important aim of these rotating units is to assemble and weld the frame and its small parts while it is positioned in the jig (this technical condition is especially necessary for steel and aluminum TIG welding), in order to ensure an optimal final frame alignment.
