Needle bar drive in a sewing machine comprising a crank driven by a connecting rod provided on the main shaft for transmitting reciprocating motion to the needle bar and by a rod connected to the needle bar gate and driven by a linear motor in order to impart to the needle bar transverse movements relative to the sewing direction. A joint type connection between the connecting rod and the needle bar is provided in order to allow a smooth rational operation to the assembly.
