Most of the coil feeders are one-way feeding. In other words, it forwards in one direction, and quantitative step feeding. However, after metal strip feeds in one direction by these coil feeders, the edge material left after the circle blanking line is broad and challenging to reuse. Consequently, it is low utilization and massive waste in the metal stamping process.
One the other hand, HE zigzag coil feeder has two-way travel. And based on different circle sizes, it adjusts the feeding length from the horizontal or vertical direction. As the distance of each circle can set in 0.5mm, and each feeding accuracy will keep in 0.08mm. So, it will save material 7% in each feeding movement.
For example, in the case below, it will save 10% of the material cost.
