Abstract

PURPOSE: To match slots and thus to prevent a band steel from getting out of position widthwise by punching slots and projections in a band steel at a pitch variant at every number of turns so that the projections will fit in each other vertically.
CONSTITUTION: A slot 4 and a projection 5 are punched on a die 3 in a band steel 1 coming from a material feed motion 2 in the direction indicated by arrow. The band steel is then taken up on a winding core 6 to form a wound core 7. In this case, the slot 4 and the projection 5 are punched at a pitch variant at every number of turns so as to come necessarily at a given angular position, at P for example, thus lying one upon another vertically. Then, a closer fitting between a concavity of the band steel 1 wound earlier and the projection 5 of the band steel 1 wound later is obtainable from shaping the projection 5 in a trigonal pyramid and forming it gradually higher in the winding direction.
