Abstract
A sewing machine for sewing stationary large surface material (13) includes at least two units (14, 16 and 15, 17) of which includes a sewing head (14, 15) and an associated shuttle box (16, 17) which are displaceably mounted for movement in the first (x) and second (y) directions substantially normal to each other. A common drive mechanism (18, 19, etc.) displaces the unit simultaneously in the first direction (x) while spaced a predetermined distance (D) from each other while an associated disengaging mechanism (35) can controllably disengage one of the units (14, 16 or 15, 17) from the common drive (18, 19, etc.) while the other unit is displaced by the common drive to thereby change the predetermined distance (D) after which the one unit is re-engaged. Preferably holding mechanisms are provided for holding the disengaged sewing head (14 or 15) and the disengaged shuttle box (16, 17) of the disengaged one of the units (14, 16 or 15, 17) substantially stationary during the displacement of the other unit, and preferably the stationary unit is maintained substantially stationary at a parked position (38) during the displacement of the other unit.
