Wire mesh making machines’opening movement

To interweave warp and weft yarns on a weaving machine, the warp wires must be separated up and down to form a gib, and then the weft yarns are drawn in, at which time each warp wire should pass through the heald eye in a certain order. When the heald frame moves up and down, the warp wires that pass through the heald eyes are lifted up and down together with the heald frame; this movement is called the shedding movement. The shedding motion is accomplished by the shedding mechanism.

The opening movement is not only a decisive element in the formation of metal nets, but also has a great influence on the structure of the nets, warp breakage and loom productivity. Therefore, a careful study of the opening process is very necessary.
