Abstract
687,610. Transformers. FIORAVANTI, G. Dec. 29, 1950 [Jan. 11, 1950], No. 31656/50. Class 38 (ii). A transformer core 5 is made by winding spirally a magnetic iron strip 1 from a spool 2, round the transformer winding 6, by means of two drums 3, 4 of which 3 is a driver and 4 a follower, the latter being moved upwards against a spring or weight as the number of turns of the spiral increases. The surfaces of drums 3, 4 may be respectively roughened and covered with rubber or leather. The first turn is made by manually looping the end of the strip through the winding window and welding it to the strip. To fill the winding window, which may be rectangular, more completely, drum 3 may be removed and the winding completed by drums 7, 8, each of which forms a pair with a corresponding drum (not shown) on the other side of the strip. The surface of the winding may be curved to fit the shape of the spiral core (Fig. 4). More than one core may link with one winding.
