(54) | Machine for operating progressively along marginal portions of shoes |
(57) For operating on shoes marginal portions of which have broken seams, resulting in
the possibility of the top portion of such seam being loose, a facility is provided
for moving the tool (250) out of operative contact with such marginal portion while
travelling in a first direction, in which the seam would be engaged with the top portion
thereof "downstream" of the seam (thus giving rise to the possibility of the top portion
being lifted by the tool), whereafter the tool and shoe are returned into operative
contact and the direction of movement of the tool relative to the marginal portion
is reversed so that the tool is caused to operate in the reverse direction progressively
along the particular marginal portion, and then the tool is once more moved out of
engagement with the shoe and moved in the first direction above the marginal portion
which has been treated as aforesaid in the reverse direction, the tool and shoe once
more then being returned into operative contact and the treatment of the marginal
portions of the shoe with the tool moving in said first direction then being continued.
