Abstract
Abstract A coil winding machine for forming edge-wound or flat-on-flat coils, featuring an indexable and rotatable die, against which the material from which the coil is to be formed is held under pressure by a wiper bar. Edge-wound coils are acted upon by a wiper bar having a surface formed thereon which serves to motivate the coil turns upwardly as they are formed so as to make room for the incoming material. The flat-on-flat coils are acted upon by a powered roller wiper bar which is actuated so as to press the material against the die, and particularly about the ends thereof as the die is rotated.
