According to the sheet thickness and the different shape, we developed
Pittsburgh lock former machine were divided into forming of 6-station,
7-station, 8-station, 9-station and 10 forms; these machines each were
installed on both sides of Pittsburgh rolls on one side and a set of Standing
Seam Rolls on the other side. for the realization of the use of a machine as
much as possible, one of the 7-station and 8-station of lock former machine a
total of 4 processing station, By adjusting the front positioning plate of 6
types of the different profile, roll these machines by high quality alloy steel
by vacuum quenching system. for safety reasons, on the cover to the strict
restrictions on the work table distance. In order to ensure product quality,
the axial and radial roller shafts are equipped with roller bearings
