A machine and a method for inserting insulating paper in the slots of armatures (1) for electric motors operating the devices for feeding, cutting, inserting the insulating paper and for indexing the armatures, wherein the automatic change and adaptation of the strokes of such devices according to the dimensions of the armature and the production rate is met. Means are provided for: feeding (12) a continuous web of insulating paper (11), transversal cutting (16) of the web into portions (5,6) of predetermined length; inserting (17) the cut and bent portions (5,6) in the slots, and indexing (24,50) the armatures. Furthermore means are provided: for feeding (14, 30, 31) the web beyond the means for cutting (16), for operating in turn (40, 40a, 41) the means for cutting (16), inserting (17) and indexing (24,50), for giving a signal (31a) proportional to the achievement by the paper (11) of a predetermined position beyond the means for cutting (16); for controlling a programmable way (60) the means for feeding (14, 30, 31) and the means for operating (40, 40a, 41) responsive to the signals of paper feeding (31a) so that portions of paper are cut in turn (5,6) of predetermined length. <IMAGE> |
