Abstract: An annular core holder form supports in rotatable fashion a toroidal core in connection with a pair of fixed support members to comprise a core holder assembly for winding wire coils on the core through the action of a revolving wire-carrying shuttle of a coil winding machine. The core holder form is intergally wound to the core through the wrapping action of the shuttle and is removable with the core. The pair of support members and the holder form have generally central first openings extending axially therethrough to permit the shuttle to thread the core, support members and holder form in order to wind the wire coils axially about the annular wall of the core. The support members have respective second openings communicating with the first openings and which are aligned with each other to permit the passage of a winding wire strand. The core holder form has two axially spaced rows of outer tooth-like projections, either or both of which can be used to rotatingly drive the holder form and toroidal core as a unit. Precision and closely wound coils of wire are continuously wrapped about successive arcuate segments of the annular walls of the holder form and core as they are exposed through the second openings to the shuttle operation. The two rows of projections of the holder form are used to restrain the axial loops of each coil of wire for securing the same against lateral movement along the ends of the core and for maintaining the alignment of the axial loops in substantially perpendicular traversement of the ends of the core.
