The principalv purpose of the invention is to
produce 'a two-ply or laminated welt which ‘is '
molded to serve the purpose of GoodyearV _welting
but avoids the necessity of grooving or beveling
of the Welt strip, while providing a proper con
tour at the inseam'edge; which may be built into
a shoe with a minimum of beating to afford a
tighter seam and a wider welt extension than
desired,

When the improved, preformed welt is stitched
to a lasted upper in accordance with the custom
ary Goodyear welting process, the welt exten
` sion projects outwardly along the sides of the
shoe and the toeportion thereof may be easily
flattened.> As the fibres of the inseam lips have
been stretched at the v'fold of the ñange by bend
ing them downwardly under pressure, internal
strain on the welt during the welt turning and
beating operations is substantially eliminated,
and only sufficient rolling or beating to flatten
the underside of the Welt extension i-s required
to prepare the welted shoe for bottom finishing
and outsoling. The distortion and damage Vto
the shoe, frequently caused by the ordinary welt
beating operation, is thus obviated by the use of
the improved welt in shoe manufacture.`
