Abstract
Method of continuously winding a saddle-shaped deflection coil flaring from a rear connection portion towards a front connection portion, in which at least one connection portion is given a convex shape during winding and in which after winding the convex connection portion is given a concave shape by means of a die, whereafter the coil turns are united to a compact assembly by means of a heating step.
