| 摘要 | Acting on a column means (3) carrying a shoe (4) being worked is a fluid-operated actuator (19) longitudinally moving the shoe (4) in synchronism with two nailing hammers (37) acting on the opposite shoe flanks. Each hammer (37) is carried by an end plate (39) oscillatably mounted to a movable block (36) along a guide structure (33) for pushing the hammer (37) towards the shoe (4). The lower hammer end (37a) is elastically urged towards the edge of the shoe vamp (5) in order to stretch it when the hammer moves towards the shoe inside before the nail is driven in. The guide structure (33) is capable of oscillation about its own longitudinal axis and acts on the shoe insole (6) in order to transmit to the hammers (37) the variations in height and inclination encountered along the longitudinal shoe. | ||||||
