Loom rapier, water jet machines with dobby ... etc., Heddle frame is an important part of weaving loom, the dynamic performance will directly affect the normal working of the loom. Loom warp breakage occurs mainly in the neighborhood of heddle frames.

Heddle frames loom photogenic links by the same carabineer control the warp law of motion are the same heddle frame lift the warp shed in accordance with certain rules under the staggered formation, and then woven into cloth on interleaved movement, so heddle frames the composition is divided into heddles, heddle frame.

Heddle frame Type

Observed heddle frame during the movement of the weaving, the dynamic forces will cause the impact force of the vertical movement of the heddle frame and the fabric tension Cause bending phenomenon. Heddle frame in the ambient temperature changes produced by the deformation force.All these factors will make the heddle frame vibration occurs in varying degrees in the operation of the loom process.The heddle frame vibration not only cause off which will also affect the production efficiency; beams also cause breakage and even the frame off opening J with resonance loom speed.So during the design of the heddle frames, necessary to study the dynamic characteristics, the heddle frame to further enhance and improve the dynamic performance.

Heddle frame Graph

Heddle frame is the structure of the thin framework classes, loom work, Heddle frame up and down the back and forth movement, under the warp tension, dynamic load, and the severe vibration is passed to the warp accelerated the warp in the comprehensive in the eyes of the friction, so you must consider to the work of the Heddle frames when the bearing and deformation factors, so when the Heddle frame production and design, the materials used must ensure that its stiffness and strength.
