Abstract: An automatic armature winding machine that is capable of winding straight and skewed stack armatures of various diameters and lengths and of achieving high percentages of slotfill is disclosed. A transfer plate for directing a plurality of wires for winding the core of the armature to a winding area in preparation for the winding operation is mounted in translational relationship to the armature core to be wound. The wires within the concentration area are simultaneously wound into the slot of the armature core by moving the wires through the armature core so that the wires are forced into the slots of the armature core. Upon completing the first winding stroke, hydraulic actuated forming blocks are radially activated to push the wires further into the slots of the armature core to make space for the subsequent turns to be wound. Thereafter, the winding stroke is repeated by moving the wires back through the armature core, after which the blocking function is repeated.
