Abstract
An object of the present invention is to provide a manufacturing system and a method for manufacturing sheet-like structures. The manufacturing system of sheet-like structures contains a loosened portion forming apparatus by which plural loosened portions, which are substantially U-shaped, are formed on a cord member, and plural linear portions, which connect each of the plural loosened portions, are formed substantially linearly; and a sewing apparatus by which each of the plural absorbing members and each of the plural linear portions are sewn with a thread member.
Claims14
A manufacturing system for a sheet-like structure comprising:
- a sheet member with a prescribed form;
- and a cord member sewn onto a predefined surface of the sheet member with a specified thread member and having an extended portion extending from an outer edge of the predefined surface on which a non-sewn area without the specified thread member is formed, the system comprising:
- a loosened portion forming apparatus to form plural loosened portions on a cord member reeled out in a specified direction, the loosened portions are substantially U-shaped and extending in the direction different to a specified direction, and plural substantially linear portions which connect each of the plural loosened portions respectively;
- an arranging apparatus to arrange each of the plural sheet members so as to be in contact with each of the plural linear portions formed by the loosened portion forming apparatus;
- a sewing apparatus to sew each of the plural sheet members arranged by the arranging apparatus and each of the plural linear portions which come in contact with the plural sheet members with a thread member;
- a thread member cutting apparatus to cut thread connecting portions which are parts of the thread member formed so as to connect a specified sheet member of the plural sheet members on which each of the plural linear portions are sewn by the sewing apparatus and other sheet members which lie adjacent to the specified sheet member;
- and
- a cord member cutting apparatus to cut cord connecting portions which are parts of the cord member formed so as to connect a specified sheet member of the plural sheet members and other sheet members which lie adjacent to the specified sheet member at a specified position.

A method for manufacturing a sheet-like structure, containing:
- a sheet member with a prescribed form;
- and a cord member sewn onto a predefined surface of the sheet member with a specified thread member and having an extended portion extended from an outer edge of the predefined surface on which a non-sewn area without the specified thread member is formed, the method comprising steps of:
- forming plural loosened portions on a cord member reeled out in a specified direction, the loosened portions are substantially U-shaped and extending in the direction different to a specified direction, and plural linear portions which connect each of the plural loosened portions respectively, substantially linearly;
- arranging each of the plural sheet members so as to be in contact with the respective plural linear portions formed in the step of forming the loosened portions;
- sewing each of the plural sheet members arranged in the arranging step and each of the plural linear portions which come in contact with the plural sheet members with a thread member;
- cutting thread connecting portions which are parts of the thread member formed so as to connect a specified sheet member of the plural sheet members on which each of the plural linear portion are sewn in the sewing step and other sheet members which lie adjacent to the specified sheet member;
- and
- cutting cord connecting portions which are parts of the cord member formed so as to connect a specified sheet member of the plural sheet members and other sheet members which lie adjacent to the specified sheet member at a specified position.
