are reduced that is to say decreased in extension as a result of which on the inside of the heel there come to be formed small inclined connection sections indicated by t1 these extend approximately until halfway through the development of the heel subsequently in the zone of the augmentations that is to say increases there come to be formed similar and opposite connection lines indicated by t2 which can be barely slightly staggered in relation to the lines t1 in fig2 the courses of the part rows in the heel t are indicated in a rough manner clearly with a very limited number of part rows even with regard to a structure made using very thick yarns in fig3 and 4 and in particular in fig3 a very simplified diagram is shown which has a greatly reduced number of decreases and increases in order to describe the structure of the heel and the method of constructing it in fig3 at indicates the arc of needles for the formation of the fabric and n needles are assumed as maximum limit of the extension of the part rows of stitches the production of the heel is carried out using a single command of the needles in order to obtain the decreases that is to say the reductions and the augmentations that is to say the increases of the individual arcs of needles and thus of the individual part rows this can be achieved very easily using the modern selection systems of the electronic type and advantageously with the exclusion of the needles by means of their release at a low level especially just higher than that.
