Problems solved by technology

[0009] However, when one roll member is disposed above another roll member, when the unnecessary portion of the upper sheet member is collected, the unnecessary portion hangs down and may inadvertently come into contact with the lower sheet member.
When this contact occurs, the next sheet member may be damaged due to friction with the above-mentioned unnecessary part, or foreign matter may adhere to the next sheet member, resulting in a decrease in quality.
In addition, when the unnecessary part after contact is firmly attached to the next sheet member, it takes unnecessary labor and time to peel off the unnecessary part, so the efficiency will be impaired.

Embodiment Construction

[0024] Next, a method of manufacturing the sheet assembly of the present invention will be described with reference to the drawings. First, the manufacturing apparatus of the sheet assembly used in the manufacturing method of this embodiment is demonstrated.

[0025] like figure 1 As shown, the manufacturing apparatus 10 of a sheet bonded body includes: a turntable unit 11 that places one of the two rolls 3 formed by winding a strip-shaped sheet member 1 on the upper side and the other roll on the lower side, and can Two volumes 3 are supported by exchanging their arrangement, and the sheet members 1 are respectively released from the above-mentioned rolls 3; the joining device 15 cuts off the top sheet member 1a discharged from the turntable part 11, and can make the formed part due to cutting. The end 1aa (cut end) is joined to the lower sheet member 1; the recovery part 13 is used to cut off the unnecessary part 1ab of the sheet member 1a by the joining device 15 (refer to...

Abstract

The present invention provides a manufacturing method for a sheet junction body. The method includes the processes of: dispatching a first sheet member and a second sheet member respectively from a first roll and a second roll arranged on the upper part and the lower part; cutting the first sheet member dispatched in the previous process; winding the unnecessary portion of the first sheet member generated by the cutting upward by using a rotation member to recover the unnecessary portion; and bonding the end of the first sheet member formed by the cutting and the second sheet member.

Description

technical field [0001] The present invention relates to a method of manufacturing a sheet-assembled body in which two or more sheet members are joined to form the sheet-assembled body. Background technique [0002] Conventionally, there is known a method for manufacturing a sheet assembly in which two strip-shaped sheet members are joined to form one sheet assembly. [0003] As a method of manufacturing such a sheet assembly, the following method is employed. That is, the sheet member is unwound from a roll in which one strip-shaped sheet member is wound, and at the time of unwinding, the strip-shaped sheet member is unwound from the next new roll near the rear end portion of the sheet member. Then, the rear end side of the previous sheet member and the front end side of the next sheet member are cut to form the rear end portion of the previous sheet member and the front end portion of the next sheet member, and the rear end portion and the front end portion of the next she...
