First and second bodies of fastener material (4, 5) advance in a first direction which is an advancing direction, the advancing direction being changed into a second direction. A pair of turn over bars (12, 13) are spaced from each other, the first and second bodies of fastener material (4, 5) advancing in the first direction to be engaged with the turn over bars (12, 13). The first and second bodies of fastener material (4, 5) are then inserted between and turned over by the turn over bars (12, 13) with the advancing direction being changed into the second direction. |
