Title:
SEWING MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/166107
Kind Code:
A1
Abstract:
Provided is a sewing machine such that, when the feed dogs are retracted, the feed dogs can be located at an adequate distance below the upper surface of the throat plate. Feed dogs 3 protrude and sink from a throat plate 1. A horizontal feed driving part 8 converts the rotation of a drive shaft 7 into a reciprocating motion in the horizontal direction and transmits the same to the feed dogs 3. A vertical driving part 9 converts the rotation of the drive shaft 7 into a reciprocating motion in the vertical direction and transmits the same to the feed dogs. A vertical position-modifying part moves the turn-back points P at both ends of the outgoing path and the return path when the feed dogs 3 reciprocate in the horizontal direction below the throat plate 1.
