ABSTRACT:
A cycle sewing machine equipped with an improved cloth feeding mechanism which is so arranged that, through rocking control of oscillating levers by a cloth feeding cam via cam rollers, a feed table is displaced in longitudinal directions of a sewing machine bed (i.e. in X directions) or in directions intersecting at right angles with the longitudinal directions (i.e. in Y directions), and by the composite movements as described above, the garment to be sewn is moved as desired with respect to sewing positions for two sewing needles vertically moving at predetermined positions, and thus, it has been made possible to simultaneously form the same seams at two positions of the garment in an efficient manner.
