Knitting machine for needle selection system

摘要

Being the needle selector for the knitting machine which does the selection needle of the working needle making use of the piezoelectric body which possesses the piezo-electric device, time motion making halfway position of the rear end and the point of the piezoelectric body which is supported movable possibly in the housing the housing keep possibly making use of body of revolution, as it is stabilized the vibration of the piezoelectric body, it is vertical to the axis body of revolution 3 in order and also section structure body of revolution 3 with the plane surface which is vertical to the plane surface of the piezoelectric body, for curve of cross direction of piezoelectric body 2 to be smaller controlled than curve of longitudinal direction, to constitute, with that the piezoelectric bodyAs it improves vibrating speed and torque furthermore, the needle selector which achieves the energy conservation is offered.
