FASTENER STRINGER PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/021409
Kind Code:
A1
Abstract:
Provided is a fastener stringer production device in which a lever-side coupling shaft (35a) for coupling one end of a link (35) and a third end (32C) of a lever (32) and a ram-side coupling shaft (35b) for coupling the other end of the link (35) and a first ram (21) are disposed arranged in a substantially straight line along the front-back direction of the first ram (21), thus making it possible to bring the input position of driving force on the first ram (21) close to the center of gravity of the first ram (21) so as to stabilize the movement of the first ram (21) in the front-back direction, and making it possible to enhance the ability of rollers to follow the rotation of a drive shaft during high-speed driving.
