摘要： PROBLEM TO BE SOLVED: To shorten the winding time of strip material blocks and moreover, to make it possible to manufacture a high-winding accuracy wound core by a method wherein in a state that the point part of the strip material block, which is wound on a winding shaft, is superposed on the rear end part of the preceding strip material block, the following strip material block is transferred. SOLUTION: In the state earlier than the time when the rear end part of a strip material block (a strip material block A) 3 is wound on a winding shaft 1, the point part of the following strip material block (a strip material block B) 3 is guided by guide pastes 65 and 66 and is arranged in such a way as to overlap with the side of the block A without colliding with the rear end part of the block A. A pressing cylinder 64 presses this point part to a transfer roller 63 and a belt 13 is made to travel in the direction shown by an arrow D by the rotation of a roller 12. Thereby, the block A is wound on the winding shaft 1, while the roller 63 is rotated by the travel of the belt 13 and the block B is transferred in synchronization with the block A in a state that the point part of the following block B is superposed on the rear end part of the block A. Accordingly, the winding time of the blocks is reduced to half and a high- accuracy winding work can be executed.
