Abstract
A double wrap brake band is manufactured from three substantially equal length strips of metal which are bonded together in a 'Y' or tuning fork shape. The bonded straps are then formed into a cylindrical shape and friction material is bonded to the inner surfaces. Operating lugs are secured at the outer free end of each strap. In the alternative, the operating lugs can be formed integral with the strap or otherwise secured to the strap either prior to or subsequent to the bonding of the straps. The lugs can be formed integral with their respective strap by deformation of the strap material. The double wrap band can also be manufactured by assembling three pre-shaped hoop members. The hoops are assembled coaxially and have an open face which is angularly displaced from the hoop adjacent thereto. The adjacent hoops are secured by welding or using a tie bar at the adjacent surfaces between the open ends.
