ミシンの布送り装置。[Scope of claim for utility model registration] A feed dog that appears and retracts through a guide groove drilled in the throat plate and performs four-movement feeding in synchronization with the vertical movement of the sewing needle;
An adjusting member whose angular position is adjustable and is pivotally supported on the sewing machine frame in order to adjust the amount of horizontal feed movement of the feed dog; In order to apply the needle, it slides back and forth on the adjustment member in synchronization with the vertical movement of the sewing needle,
and a sliding member operatively connected to a feed dog, wherein the adjustment is such that the horizontal feed movement by the feed dog starts from a predetermined position near the front end edge of the guide groove on the operator side. A cloth feeding device for a sewing machine, characterized in that a pivot shaft of the member is provided at a position where the sliding member turns back and forth in its reciprocating motion.
