Abstract
Method and device for feeding a band or web into a downstream machine, including two grips that serve for the stepwise advancing of the band, the grips moving in synchronism to and fro in opposing directions. The grips are alternately coupled with the band or web each during its course in a determined direction in order to impart to the latter a zigzag advancing motion. The driving frequency of the advancing device is in this case half as high as the cadence of the following tool and very high cadences can be achieved.
