Abstract
A sewing machine having a cylinder bed feeds cloth in the direction orthogonal to the longitudinal direction of the cylinder bed, with a main feed dog and differential feed dog provided in the cylinder bed projecting from a bed main body of the sewing machine. The main feed bar, differential feed bar, main feed oscillating shaft and differential feed oscillating shaft for moving each feed bar back and forth, and front and rear vertical oscillating shafts for moving both feed bars up and down are provided in the cylinder bed, while all other mechanisms for the main feed dog and differential feed dog are provided inside the bed main body, so that the cylinder bed may be designed thinly.
