PROBLEM TO BE SOLVED: To solve the problem that the number of members may be increased or a work process may be complicated if trying to give a high grade feeling to a surface (trim cover) of a sheet with a wadding material.SOLUTION: Portions which are one-side ends of a plurality of trim cover pieces 14-1a to 14-1c and are not lined by a wadding material 20 are defined as sewing margins 14-1ar, 14-1bl, 14-1br and 14-1cl and a first sewing part 31 is formed by sewing the sewing margins. A long wadding material 22 is overlapped on a rear side of the continuously formed trim cover piece, and a second sewing part 32 is formed by sewing the trim cover piece, the wadding material and the long wadding material in both ends of the continuous trim cover piece. A third sewing part 33 is formed by sewing the trim cover piece and the long wadding material in the sewing margins on both sides of the first sewing part, and a plurality of trim cover pieces with the wadding material are continuously formed, thereby forming the trim cover.
【課題】ワディング材付シートの表皮(トリムカバー)に高級感を持たせようとすると、部材数が増加したり作業工程が複雑化する。【解決手段】複数枚のトリムカバー片14−1a〜14−1cの一端でワディング材20で裏打ちされていない部分を縫い代14−1ar、14−1bl、14−1br、14−1clとし、縫い代を縫製して第1の縫製部31を形成する。連続成形されたトリムカバー片裏側に長尺のワディング材22を重ね、連続したトリムカバー片の両端でトリムカバー片、そのワディング材、長尺のワディング材を縫製して第2の縫製部32を形成する。第1の縫製部の両側における縫い代でトリムカバー片、長尺のワディング材を縫製して第3の縫製部33を形成して、複数のワディング材付のトリムカバー片を連続成形してトリムカバーが形成される。【選択図】図3
