Abstract: 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.

Abstract: The invention pertains to a device adapted to apply thermoplastic cement for assembling shoe vamp sides, comprising a pair of heater units leading to feet suitable to spread cement along the edges of a shoe insole and a pair of supporting arms for said heater units fixedly mounted with respect to each other and connected to each other at their free ends by means of a pin, operated by an actuator, which can be disposed at a predetermined height above the insole. Each of said heater units is provided with a slide bar disposed parallelly to the axis thereof, axially and slidably engaged within a slide hole obtained in a small block carried by said supporting arms.
