    摘要: First and second body materials are overlapped on each other and fed along the length direction thereof. A side gusset material is temporarily joined to the second body material and subsequently divided by a dividing device to form a pair of opening edges. When the first and second body materials are overlapped on each other, the opening edges come into alignment with a fragile line of the first body material. The side gusset material is temporarily sealed to the first and second body materials by a temporary sealing device to form a temporary sealing part. The first body material is guided, divided along the fragile line, and folded at the divided edge. Due to the guiding of the body material and to the temporary sealing part, the side gusset material is opened at the position of the opening edges, and an open surface is formed. An end surface material is then positioned on the body material, and is overlapped on the folded portion of the body material and the open surface of the side gusset material.

    摘要: A joint apparatus (40) that joins a pouch body (210) to a spout (200), including: a spout holding unit (26) that holds the spout (200); a positioning mechanism (70) that positions the pouch body (210) with respect to the spout (200); and a joint mechanism (65) that joins a pouch mouth (212) of the pouch body (210) to the spout (200). The positioning mechanism (70) has a pouch-body moving unit (95) that moves the pouch body (210) toward the spout (200), a contact member (120) having a contact part (122) that comes into contact with an end (214) of the pouch mouth (212), and an absorption mechanism (103) that absorbs a part of a force acting on the pouch body (210) when the end (214) of the pouch mouth (212) comes into contact with the spout (200) or the contact member (120).
