ABSTRACT:
In a pulling over and toe lasting machine the construction of the gripper assemblies (12) and their mountings is simplified firstly to enable the assemblies to be standardized and secondly, by means of a simple manual operation, readily to be located and oriented in relation to the shoe support means (10) in accordance with the shoe style to be operated upon. Furthermore, the most heelwardly disposed gripper assemblies (No. 2 gripper assemblies) are mounted each on a slide-way inclined at about 17.degree. to the longitudinal center line of the machine, and a single mechanism firstly allows their positions along the slide-ways to be simultaneously adjusted and secondly, by means of a fluid pressure operated piston-and-cylinder arrangement, allows them to effect a heelward pull on an upper gripped thereby.
