The invention provides a multi-needle sewing machine forming a novel decorative needel-track structure having elasticity under a simulation double-ring compared with conventional decorative needel-track structures under the double-ring. The multi-needle sewing machine consists of a plurality of needles, curved needles and hooks, wherein the plurality of needles are parallel in a direction orthogonal with a textile fabric feeding direction and vertically move, the curved needles are used for maintaining a lower decorative line and only carry out synchronous reciprocating movement with needle vertical movement toward a needle arrangement direction. When in going movement, the curved needles hook a needle thread loop; when in returning movement, the curved needles depart from the needle thread loop. The hooks and a main shaft carry out the reciprocating movement in a linkage manner. When in going movement, the hooks are clamped with the lower decorative line of a front end part of the curved needles and move toward the textile fabric feeding direction and a front side expands to form the next line track in order to form a loop which the end needle enters in. |
