- Process in accordance with Claim 1, characterised by the fact that the said re-stitching comprises the operation of transferring the stitches (4) to a re-stitching mounting.
- Process in accordance with Claim 1, characterised by the fact that if the number of stitches (4) in the first half-row is different from the number of stitches (4) in the second half-row (y), those stitches (4) which are not included in the aforementioned association are likewise re-stitched.
- Process in accordance with Claim 1, characterised by the fact that the inverting and subsequent re-positioning of the stocking (5) are effected by means of a pneumatic turning tube (8) which is coaxial with the stocking (5), being subjected to a predetermined reciprocal movement in the direction of its own longitudinal axis (a-a), in such a way as to allow insertion into the stocking (5) on the side of the toe (51), to engage the border of the top (50), and to allow the extraction for turning the stocking (5) with the top (50) thus engaged.
