Abstract (en)
The invention relates to a cloth feeding device of a sewing machine. The cloth feeding device includes a feed dog (101) configured to feed a workpiece in a horizontal direction (X), a horizontal feeding shaft (104) configured to rotate about its axis in a reciprocating manner to move the feed dog (101) back and forth, a transmission mechanism (106-109, 20) configured to convert a rotation of a driving shaft of the sewing machine into the rotating motion of the horizontal feeding shaft (104) such that an amount of rotation of the horizontal feeding shaft (104) is adjustable, a feeding amount adjusting mechanism (10), and a forward-reverse switching means for switching the workpiece feeding direction between a forward feeding direction and a reverse feeding direction. The feeding amount adjusting mechanism (10) has a feed adjusting dial (44, 64) operable to set a cloth feeding pitch, an abutting member (50, 70) configured to linearly move in accordance with a rotating operation of the feed adjusting dial (44, 64), and a feed adjusting member (42, 62) having a cam face (42a, 62a) on which a distal end of the abutting member (50, 70) abuts. The feed adjusting member (42, 62) is coupled to the transmission mechanism (106-109, 20) and rotatably supported by a sewing machine frame. The cam face (42a, 62a) of the feed adjusting member (42, 62) is continuously smooth and flat.
