Abstract
Apparatus for forming a form wound stator coil from a bobbin has means for clamping the straight portions of the bobbin to define the straight portions of the each leg of the coil. It also has means for bending the bobbin to predetermined radii to form arms extending from the straight portions of each leg of the coil to each nose of the coil. Means are provided for bending each arm to a predetermined radius. Means are further provided for bending the nose portions to a predetermined angle. Means for providing a drop to the arm portions of the coil relative to the stator bore are also provided. Means for forming the leads of the bobbin to a predetermined configuration are also provided. Hydraulic means for powering the apparatus and a system for controlling the hydraulic means are also disclosed.
