Document Type and Number:
WIPO Patent Application WO/2019/021413
Kind Code:
A1
Abstract:
Provided is a fastener stringer production device in which a lever-side coupling shaft (55a) for coupling one end of a link (55) and a third end (52C) of a lever (52) and a ram-side coupling shaft (55b) for coupling the other end of the link (55) and a second ram (41) are disposed arranged in a substantially straight line along the vertical direction of the second ram (41), thus making it possible to bring the input position of driving force on the second ram (41) close to the center of gravity of the second ram (41) so as to stabilize the movement of the second ram (41) in the vertical direction, and making it possible to enhance the ability of rollers to follow the rotation of a drive shaft during high-speed driving.
