<p>A method and a device for stretching hosiery articles such as socks, knee socks and the like on a steaming form. The straight portion (12) opposite to the foot shape (11) of the steaming form (10) has a friction surface for engagement with the band portion (1d) of the sock (1) and means are provided for varying the friction surface and releasing the band portion at the end of the steaming step, in order to withdraw easily the sock in an unloading station. The friction surface may comprises a plate (31) having a plurality of holes (33); a plurality of retractable tangs (34) that engage with the holes (33); means for reciprocating the retractable tangs with respect to the holes. This way the tangs hook the band portion of the sock when they protrude from the holes and leave it free to slide on the plate when they are retracted. The reciprocation between plate and sheet causes the movement of the blades to protrude or to retract with respect to the holes. <IMAGE></p> |
