An improved sheet forming machine and method of making same are provided wherein such machine employs a first set of clamp assemblies and associated moving devices for serially moving the sheet or sheet material along fixed parallel rails through a succession of working stations and a second set of clamp assemblies which cooperate with the first set of clamp assemblies in a non-interfering manner and grasp and hold opposite side edge portions of the sheet material the full extent of the stations along the rails, and the second set of clamp assemblies are adapted to provide precise grasping and holding of such opposite side edge portions of the sheet material along such full extent to enable modification of the sheet material at each successive station with optimum precision. The machine also has improved apparatus for adjusting and holding the distance between the parallel rails.
