The kinematic Design of Beating-up Mechanism for Water-jet Loom Series Modified from Air-jet Loom

For Toyoda looms with air-jet weft insertion,the beat-ing-up mechanisms together with those of Tsudakomawater-jet looms are analyzed.Then by changing thecrank length of the four-bar-linkage for the air-jetlooms to get four specifications of reed travel correspond-ing to the series of Tsudakoma water-jet looms,it canbe proved by comparisons of displacements,velocities,accelerations and transmission pressure angles that thosetwo series of mechanisms have very similar kinematicproperties.So the possibility of developing a series of wa-ter-jet looms modified from Toyoda air-jet looms isproved.It is beneficial to save the machine cost andbroaden the machine types.

The kinematic Design of Beating - up Mechanism for Water - jet Loom Series Modified from Air - jet Loom

For Toyoda looms with air - jet weft insertion , the beating - up mechanisms together with those of Tsudakoma water - jet looms are analyzed. Then by changing the crank length of the four - bar - linkage for the air - jet looms to get four specifications of reed travel corresponding to the series of Tsudakoma water - jet looms, it can be proved by comparisons of displacements, velocities, accelerations and transmission pressure angles that those two series of mechanisms have very similar kinematic properties. So the possibility of developing a series of water - jet looms modified from Toyoda air - jet looms is proved. It is beneficial to save the machine cost and broaden the machine types.
