An apparatus for inserting coil branches (13a, 13b) of pre-wound wire coils and cover wedges (14) into slots (11) of a dynamoelectric machine core (10), comprises a first pusher assembly (50) having an insertion stroke for advancing through the bore (10') to insert the coil branches into the slots (11) and a second pusher assembly (96, 97) configured to push the cover wedges (14) into the slots (11) along the coil branches. The second pusher assembly comprises first and second-movable supports (96, 97) for pushing first and second groups of wedges (30, 32, 33, 35, 36, 38) into respective slots (11) during a same insertion stroke. The apparatus is provided with radial arms (5-6', 57', 58') moveable in the radial direction (R) of the core (10) for entering the slots (11) to push coil branches (26") towards the bottom of the slots (11). At least one form member (131-136, 141-143) may be provided for impeding the insertion of a branch of a coil in the respective portion of the slot during at least one insertion stroke of the first pusher assembly (50).
