Fastener material advancing direction changing apparatus

摘要

First and second bodies of fastener material 4 and 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 and 13 are spaced from each other, the first and second bodies of fastener material 4 and 5 advancing in the first direction to be engaged with the turn over bars 12 and 13. The first and second bodies of fastener material 4 and 5 are then inserted between and turned over by the turn over bars 12 and 13 with the advancing direction being changed into the second direction.

主权项

1. A fastener advancing direction changing apparatus in which first and second bodies of fastener material are fed longitudinally thereof to advance in a first direction which is an advancing direction, the advancing direction being changed into a second direction, the apparatus comprising:
a pair of turn over bars spaced from each other in a third direction normal to the first and second directions and inclined at a predetermined angle with respect to the first direction; and a guide device by which the first and second bodies of fastener material are guided to advance in the first direction to be directed to and engaged with the turn over bars, the first and second bodies of fastener material being then inserted between and turned over by the turn over bars with the advancing direction being changed by the turn over bars from the first direction into the second direction so that the first and second bodies of fastener material come close to each other and then advance in the second direction in a state of being opposed to each other, the first and second bodies of fastener material being disposed parallel with each other and along a plane when advancing in the first and second directions.
