ABSTRACT:
A device for pneumatically tensioning and reversing tubular manufactured articles such as socks, upon completion, by a circular knitting machine. The device includes a small diameter rotating needle cylinder. The device has an external tubular casing and an internal element for forming an interspace with an annular cross section for pneumatic tensioning. The internal element forms an axial passage inside which the manufactured article is turned inward and reversed during a pneumatic operation where the article is reversed and conveyed away. Both the tubular casing and the internal element consist of two sections with different diameters. Upper sections with a smaller diameter are accommodated within the needle cylinder and the lower sections with a larger diameter are located outside and adjacent to the needle cylinder. Structure is provided for forming an annual discontinuity between the two sections of the internal element such that after a phase involving formation with pneumatic tensioning, a second phase involving inward turning and reversal can be performed along the end edge of the tubular section of the internal element with a larger diameter and within the section.
