Manufacturing method, manufacturing apparatus and manufacturing jig of trim cover surface material

A manufacturing apparatus of a trim cover surface material, the trim cover surface material including:

• an outer material which is formed with a plurality of through holes by a predetermined pattern;
• and a wadding material laminated on the outer material, the trim cover surface material being formed with stitches that sew together the outer material and the wadding material at gap portions between through hole patterns, the manufacturing apparatus comprising:
• a drilling machine and a sewing machine which are installed sequentially on a production line;
• and
• a jig which holds the outer material and the wadding material, wherein:
• the jig includes:
• a first frame configured to hold an outer periphery of the outer material;
• and a second frame configured to hold an outer periphery of the wadding material by overlapping the wadding material on the outer material which is held by the first frame;
• the drilling machine includes an installing part on which the jig is installed;
• the drilling machine forms the through holes at the outer material which is held by the jig which is installed on the installing part;
• the sewing machine includes an installing part on which the jig is installed;
• and
• the sewing machine forms the stitches at the outer material and the wadding material which are held by the jig which is installed on the installing part.
