Abstract: An improved blind stitch sewing machine includes a machine table, a main housing fixed on the machine table, a head housing located at one side of the main housing, a needle mechanism unit coupled with the head housing, a driving unit coupled with the machine table and adapted to drive the needle mechanism unit, and a fabric pushing member coupled with the driving unit. The driving unit includes a main shaft, an auxiliary shaft, a first transmission assembly and a second transmission assembly. The main shaft is journalled on the main housing and is drivable to effect a unidirectional rotation. The first transmission assembly interconnects the main shaft and the auxiliary shaft so as to convert the uni-directional rotation of the main shaft into reciprocal rotation of the auxiliary shaft. The second transmission assembly interconnects the auxiliary shaft and the fabric pushing member so as to convert the reciprocal rotation of the auxiliary shaft into reciprocal vertical movement of the fabric pushing member.
