<p>A single-cylinder circular hosiery-making or knitting machine particularly for manufacturing tubular items closed at one of their axial ends, the machine comprising a needle cylinder (2) and a circular plate (8) which coaxially faces the needle cylinder (2) in an upward region. The circular plate (8) is composed of two halves (13, 16), a first half (13) of the circular plate (8) being pivoted to a first supporting structure (15) about a diametrical axis (14) which is substantially parallel to the diametrical connecting plane of the two halves (13, 16) of the circular plate (8), the first half (13) of the circular plate (8) being provided with radial grooves (50) which accommodate pairs of hooks (51a, 51b) which can be actuated along the corresponding groove so as to engage or release loops or portions of loops of knitting formed by the needles (4) of the needle cylinder (2). Elements (23, 24, 25, 27) are provided for overturning the first half (13) of the circular plate about the diametrical axis (14) to transfer it from a first position, which is co-planar with respect to a second half (16) of the circular plate (8), to a second position, which is overturned below the second half (16) of the circular plate (8), and viceversa. The first half (13) of the circular plate (8) is rotatable, in the second position, rigidly with the needle cylinder (2) about the axis of the needle cylinder with respect to the second half (16) of the circular plate (8). <IMAGE></p> |
