Process for manufacturing a semifinished item for the production of briefs with a circular knitting machine for knitwear,stockings and the like

摘要

The process comprises: a first step of formation of an elastic border (1), a second step of formation of a tubular body (2) of knitting starting from the elastic border (1) for a preset number of complete rows, a third step in which a first group of needles and a second group of needles of the machine, which operate on mutually angularly spaced portions of the tubular body, are excluded from working to define a pair of missing portions (3a,3b) which constitute the leg apertures of the briefs; the needles excluded from working gradually increase in number for a widening of the missing portions (3a,3b). In the second step, during the knitting of the last complete rows of the tubular body (2), a preset number of needles, which operate in the mutually angularly spaced regions, and, in the third step, a preset number of needles proximate to the first group and to the second group of needles, are fed with yarn and with elastic thread for the formation of an elastic border (6a,6b) around the leg apertures.
