Types and technical requirements of heald rods

1. Classification of heddle rods
(1) Classification according to the cross-sectional shape of the heddle rods: O-shaped; J-shaped; C-shaped (see Figure 6-1).



(2) Classification according to the purpose of the heddle threading rod:
① Heddle threading rod for closed O-shaped heddle ear healds.
②J-shaped heddle ear piece is used to wear the heddle rod.
③C-shaped heald lug steel sheet heald wear-through rod.
2. Specifications and technical requirements of the heald penetration rod
(1) Specifications and technical requirements of the O-shaped heald penetration rod
(1) According to the usage of the heald penetration rod. O-shaped heald rods can be divided into two types: A-shaped and B-shaped.
①A-shaped: The form and specifications of A-shaped heald rod are shown in Figure 6-2 and Table 6-1.



②B shape: The wedge-shaped end is connected to the drawing-in rod of the Uster automatic drawing-in machine. The form and specifications of B-shaped heald rods are shown in Figure 6-3 and Table 6-2.



(2) The O-shaped heald rod should be cold-rolled from stainless steel (2Cr13, 3Cr13) or manganese steel (60Mn, 65Mn) and other materials, and made by heat
treatment.
(3) The technical requirements of O-shaped heald penetration rods are:
① The tensile strength of the heald penetration rod σb =1300~1500N/mm2.
② The area around the heald rod is completely smooth and has no burrs.
③The surface of the heald rod is flat and clean, with smooth surroundings and no burrs.
④The heddling rod needs to be straightened.
(2) Specifications and technical requirements of J-shaped heald penetration rod
(1) The specifications of J-shaped heald penetration rod are: 16mm×2.1mm, and its main dimensions are shown in Figure 6-4.
(2) J-shaped heald rods should be cold-rolled from stainless steel (2Cr13, 3Cr13) or manganese steel (60Mn, 65Mn) and other materials, and made after heat treatment.
(3) The technical requirements for J-shaped heald penetration rods are:
① The tensile strength of the heald penetration rod σb=1290~1400N/mm2 .
②The surface of the heald rod is flat and clean, with smooth surroundings and no burrs.
③The heald rod needs to be straightened.
(3) Specifications and technical requirements of C-shaped heald penetration rod
(1) The specifications of C-shaped heald penetration rod are: 22mm×1.7mm, and its main dimensions are shown in Figure 6-5.



(2) The C-shaped heald rod should be cold-rolled with 2Cr13 or 3Cr13 and other materials and made after heat treatment.
(3) The technical requirements for C-shaped heald penetration rods are:
① The tensile strength of the heald penetration rod σb=1290~1400N/mm2 .
②The surface of the heald rod is flat and clean, with smooth surroundings and no burrs.
③The heald rod needs to be straightened. Straightness ≤ 0.3m.
