Abstract

A multilayered latitude passing device for ribbon loom is disposed at a base of the ribbon loom and includes a latch needle unit and a latitude yarn hook unit. The latch needle unit is disposed at a side of the fastening seat and winds the horizontal shaft to reciprocate and rotate. The latch needle unit has plurality of latch needles. The latch needles are vertically arranged, wherein the length is gradually converged from the top to the bottom. The latitude yarn hook unit is disposed to another side of the fastening seat and winds the vertical shaft to reciprocate and rotate. The latitude yarn hook unit has a plurality of latitude yarn hooks. The latitude yarn hooks are vertically arranged and sequentially spaced at intervals in the rotation direction of the rotary arm. With the latch needles that are vertically arranged and the length that is gradually converged from the top to the bottom, the latitude yarn hooks that are vertically arranged and sequentially spaced at intervals in a rotation direction of the rotary arm such that latitude yarn hooks can be simultaneously moved to corresponding latch needles to complete the latitude passing stroke to achieve the effect of multilayered latitude passing, thereby further improving the entire production efficiency.
