Description

Technical Field

[0002] The heald frame is a crucial component of the loom, responsible for controlling the up-and-down movement of the warp yarns during the weaving process, allowing the weft yarns to pass through. Heald frames are typically constructed from sturdy metal materials such as steel or aluminum alloy to ensure stability and durability even at high speeds. They typically consist of multiple healds, each of which independently controls the raising and lowering of a group or a single warp yarn. The up-and-down movement of the heald frame achieves the desired rise and fall of the warp yarns, forming the desired fabric structure and pattern. The design and quality of the heald frame directly impact key fabric characteristics such as density, thickness, pattern clarity, and production efficiency.

[0003] In high-speed looms, the heald frames must be able to withstand rapid and frequent movements, making the selection of materials and processing technology crucial. Currently, heald frames are primarily manufactured from high-strength alloys to ensure sufficient strength and toughness. However, this use of alloys as the primary structural material increases the overall weight of the heald frames, reduces their flexibility, and places heavy loads on their side structures, shortening their overall service life.
