Abstract (en)
[origin: EP2617884A1] A cloth feed adjusting device of a sewing machine includes a turning unit (86) configured to change a stitch pitch, a cam member (78, 79) configured to change a rotation angle of the turning unit, first and second adjusting members (76, 77) configured to set a rotation angle of the cam member, and a pitch switching actuator (80) configured to switch a contacting state between a cam portion (781,791) and contact portions (731, 741) of the turning unit. The cam portion is formed such that a forward feed adjusting portion (785, 795) for adjusting a forward feeding pitch and a backward feed adjusting portion (786, 796) for adjusting a backward feeding pitch face each other and have a border at an intermediate position (784, 794) at which a stitch pitch becomes 0. The cloth feed adjusting device includes a feed direction switching actuator (81) configured to moves the contact portion between the forward feed adjusting portion and the backward feed adjusting portion to switch a stitch direction, and a control unit (90) configured to drive, at the time of starting the operation of the pitch switching actuator, the feed direction switching actuator in a range in which the stitch direction is not switched.
