Abstract
A method of joining sheet members together, which enables two sheets to be joined while conveying these sheets and reducing a cause of inferior products as much as possible. The method of joining sheet members includes: bonding an end of a new sheet member to a surface of a preceding sheet member through an adhesive material to form a joined part; and cutting the preceding sheet member at a position rearward of the joined part to join the preceding sheet member with a new sheet member, wherein the preceding sheet member is secured to the new sheet at a position rearward of the joined part. In addition, in the method of joining sheet members, the securing is carried out by welding using laser beam.
Claims3
