(57) The present invention relates to an improved industrial-use sewing machine adapted
to perform two sequential seams, and to vary either leftwardly or rightwardly the
stitch felling direction. The sewing machine comprises two sewing units, respectively
a horizontal needle bar sewing unit and a vertical needle bar sewing unit, arranged
in a proper sequence, along a feeding direction of a cloth article to be seamed. Along
this feeding direction, under a supporting panel for supporting the cloth article
to be seamed, are arranged: a first guide defining a first passage for the two parts
of the cloth article to be seamed or sewn, which parts are arranged with a mutually
facing relationship in a substantially vertical plane near the horizontal needle bar,
and a second guide which is arranged between the first guide and the vertical needle
bar sewing unit. The second guide, in particular, defines a second passage for the
two parts of the cloth article being sewn, and is provided with means for bending
the two sewn parts in a direction transversal of the cloth article feeding direction,
so as to bring the two parts under either one or the other of the two cloth article
portions extending on opposite sides starting from the two mentioned parts and which
are arranged on the bearing panel so as to allow the vertical needle bar sewing unit
to perform a felling sewing or seaming operating, either leftwardly or rightwardly,
depending on requirements, without requiring any fitting operations on the sewing
machine.
