Gripnail Corp. now has a spacing acquisition module or “SAM” to determine pin spacing for its Power Pinner 50 multi-head coil-line welders. The module is mounted on the coil line after the metal has been notched but before it is flanged. It “reads” the notches in the metal’s edge and converts it to data used to fire the pinner. It measures the distance between the notches and calculates the number of pins required to meet spacing requirements. A Power Pinner 50 with a SAM can be installed on most coil lines and used on high- or low-velocity duct, officials say. It can run at speeds up to 50 feet per minute. The module will be on display at booth No. 3937 during the AHR Expo this month in Orlando, Fla.
