Method of bonding strip-shaped members to each other and apparatus configured to bond strip-shaped members to each other

An apparatus configured to bond a long strip-shaped first member and a long strip-shaped second member to each other, the apparatus comprising:

• a conveying portion configured to convey the first member in a longitudinal direction of the first member;
• and
• a bonding portion configured to bond the second member to the first member being conveyed by the conveying portion and send out the second member along with the first member conveyed by the conveying portion, wherein
• a width of the second member in a shorter direction of the second member is larger than a width of the first member in a shorter direction of the first member,
• the second member is arranged in a state of being wound around a center axis along the shorter direction of the second member in the bonding portion to form a roll of the second member such that respective ends of the second member in the shorter direction of the second member are freed,
• the bonding portion includes a pair of support rollers arranged so as to sandwich the roll of the second member in a conveying direction of the first member and configured to support the first member being conveyed and wrap the first member on an outermost layer of the roll of the second member so as to bond the second member to the first member, and
• the bonding portion is configured to bond the second member to the first member such that the shorter direction of the first member is aligned with the shorter direction of the second member and respective ends of the first member in the shorter direction of the first member are placed between the respective ends of the second member in the shorter direction of the second member.

• the conveying portion is configured to convey the first member above the roll of the second member,
• the bonding portion includes a roll holding unit configured to hold the roll of the second member to bring a side face of the roll of the second member into contact with the first member being conveyed by the conveying portion,
• the bonding portion is configured to bond the second member to the first member such that the shorter direction of the first member is aligned with the shorter direction of the second member and respective ends of the first member in the shorter direction of the first member are placed between the respective ends of the second member in the shorter direction of the second member, and
• the roll holding unit is configured to shift a position of the roll of the second member relative to the first member so as to change the size of a contact area between the first member and the side face of the roll of the second member.
