PURPOSE:To enable to simply and seemly coat a cover by a method wherein firstly two sheets of skin material are put one on the other opposing their face sides to each other and secondly only the edges of openings are joined from the back side in advance and finally the outer peripheral edge of the one sheet is past through the joined openings successively in order to turn the one sheet of the skin material inside out with the joined part as the boundary of inversion. CONSTITUTION:Firstly, two sheets of skin material 1 and 1 are put one on the other opposing the respective face sides 1c and 1c to each other and only the end deges 1d and 1d of openings 1a and 1a are sewed up each other from the back side along the whole periphery, excluding notches 1b and 1b. Secondly, only the one peripheral edge 1e of un-joined edges 1e and 1e is past through the joined openings 1a and 1a successively so as to invert the whole cover with the sew line as the boundary of inversion in order to form the cover A into an empty sack with an opening near its center, within which a cushionig body is arranged so as to be housed therein. Thirdly, the un-sewed-up outer peripheral edges 1e and 1e are joined by sewing-up from the face sides after being tucked in. Because the cushioning body is wrapped in the cover, which is formed into one sheet by inverting the one side of two sheets of skin material 1 and 1 joined together in advance as mentioned above, the joining between the outer peripheral edges can be simply performed and further the joined part of the outer peripheral edges can be prevented from being exposed to the outside of the cover. |
