Abstract
In a tack seat lasting machine the wiper plates (90) first effect an 'advancing+inwiping' movement and thereafter an 'inwiping only' movement, while a central wiping member (76), about which the wiper plates pivot, advances only. To achieve this motion, the member (76) is supported by an arcuate projection (78) which is accommodated in grooves (83) formed in the wiper carriers (88), the center of curvature of the projection and grooves coinciding with the axis of the wiper plates. Thus, the central wiping member is always brought to the same 'back tack' position (but the shoe can be adjustably positioned relative thereto by varying the fore-and-aft position of the heel band (20)). The nail pattern is adjustable, without affecting the back tack position, by limiting the stroke of the cylinder controlling the operation of the wiper assembly.
