To provide a strip connecting apparatus and a method therefor which are less costly, short in welding time and high in welding quality. A strip connecting apparatus is provided with: a surface coating removing device for removing insulative surface coating of end portions, to be welded, of a leading strip and a trailing strip before cutting the strips; a cutting device for cutting the end portions, to be welded, of the leading strip and the trailing strip; and a welding device for overlapping the cut end portions of the leading strip and the trailing strip and seam welding the cut end portions with each other.
Claims14
A strip connecting apparatus comprising:
- a surface coating removing device for removing an insulative surface coating from respective surfaces of a leading strip and a separate trailing strip before cutting the strips, said surface coating removing device being operative to remove a portion of said insulative coating, such that a portion of surface coating remains on ends of the respective strips;
- a cutting device for cutting end portions of said leading strip and said trailing strip where the insulative coating has been removed;
- and
- a welding device for overlapping said cut end portions of said leading strip and said trailing strip and seam welding said cut end portions with each other.
A strip connecting method comprising the following steps of:
- removing a surface coating of portions of a leading strip and a separate trailing strip before cutting the strips, said removing of the insulative surface coating being performed at a location separated away from respective ends of the leading strip and the trailing strip such that a portion of surface coating remains on the ends of the respective strips;
- cutting end portions, to be welded, of the leading strip and the trailing strip where the surface coating has been removed;
- and
- overlapping the cut end portions of the leading strip and the trailing strip and seam welding the cut end portions with each other.
