Summary:PURPOSE: Provided is a stitcher structure for a tire which reduces contact area with a band case in comparison with a cylindrical roller so that it prevents the band case from being released from a band drum. CONSTITUTION: The stitcher structure for the tire comprises the parts of: plural connection bars(3,3',3'') which are attached to lower side of a band supplier(2) by a fixing bolt(4), with fixing a sheet-shaped support plate(5); a cylinder(6) which is fixed at one upper edge of the support plate; a bracket(9) which is connected to a load(6a) of the cylinder; a mobile plate(7) which is moved along lower side of the support plate through a linear motion guide(8); a rotation roller(10) which is connected between a linear motion guide(11) and a bearing; and a drive motor(12) which is placed under the mobile plate. 본 발명은 타이어용 스티쳐의 구조에 관한 것으로, 밴드공급기에 부착된 지지플레이트의 하부에 이동플레이트가 구비되고, 이 이동플레이트의 하부에 회전롤러가 설치되되, 이 회전롤러의 외주면에는 연성우레탄이 설치되고, 이 연성우레탄의 외주면에 다수개의 치차형롤들이 분리/설치되는 구조로 이루어져, 공급되는 재료의 단차에 따라 상기 회전롤러의 외형(높낮이)이 변화되면서 재료에 균일한 압착력을 가할 수 있음은 물론, 기존의 원통형롤러에 비해 밴드케이스와의 접촉면적을 감소시켜 밴드케이스가 밴드드럼으로부터 이탈되는 현상도 방지할 수 있도록 된 것이다.
