Claims12
In a method wherein overlying portions of generally flat, non-metallic strap are secured by a metallic seal having a web and flanges, said method including the steps of applying forces to the seal web and flanges to fold the flanges at the seal corners onto overlying strap portions and to crimp the seal in a transverse direction thereof, the improvement comprising causing the overlying strap portions and the seal web to assume a similar bow away from the seal flanges under opposing component forces applied to the seal flanges to seat longitudinal edges of the overlying strap portions snugly within the seal corners, whereby such seated strap portions serve as fulcrums about which the seal flanges are folded during the continued application of the opposing component forces and are firmly interlocked with the seal during crimping.
