Abstract of the Invention In a tack seat lasting machine the wipers are moved lengthwise of the shoe and inwardly thereof under the action of a single piston-and-cylinder arrangement. For setting the appropriate "nail pattern", the action of said piston-and-cylinder arrangement is terminated by adjustable stroke limiting means, comprising a valve actuated by an abutment, the valve moving with the wipers and the abutment being adjustably positioned in the path of the valve. A further abutment, spaced from the first-mentioned abutment, controls the rest position of the wipers. The wipers are arranged symmetrically centrally of the machine, and the heel band is capable of clamping a shoe in the position in which it is presented by the operator, thereby avoiding the need to adjust the wipers for lefts and rights.
