(57) A heel seat lasting machine has a shoe support (110) swingable between a loading
position and a lasting position. In the loading position a holddown (5) provides a
three-point (8, 9, 10) contact with the heel seat of the shoe and sets a height datum
against which the shoe support (110) jacks the shoe. The toe support (14) is then
positioned by moving a toe-engaging element (15) into engagement with the shoe toe
and, following such engagement, raising the toe support (14) against the shoe. The
shoe width in the heel breast region is measured by shoe-engaging members (29, 30)
mounted on the holddown support. The members (29, 30) also serve to orient the centre
line of the heel seat on the centre line of the wipers (46). The width measuring function
of the members (in this case mechanically by Bowden cable (42)) serves to position
the heel band (45) lengthwise of the shoe, set up an intermediate position of the
wipers (46) (in which they act as a holddown at the lasting position) and determine
the "end of inwipe" position of the wiper plates (46).
