(2) Classification according to the use of heddle rods:
\u2460 Heddle rods used for closed O-shaped heddle ear healds.
\u2461The J-shaped heddle ear piece is used for the heddle threading rod.
\u2462C-shaped heald lug steel sheet heald wearing 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.
\u2460A-shaped: The form and specifications of A-shaped heald rod are shown in Figure 6-2 and Table 6-1. <\/P>
