DEVICE AND METHOD FOR GUIDING BANDS TO BE JOINED TO EACH OTHER ALONG THE LONGITUDINAL EDGES THEREOF USING GUIDE ROLLERS

摘要

A device and a method for guiding bands to be joined to one another along their longitudinal edges, in which bands are guided via deflection rollers to a joining position. The device according to the invention provides that the deflection roller located closer to the joining position is configured as a conical roller, the deflection roller arranged upstream of this conical roller in the running direction of the band being also configured as a conical roller or as a deflection roller having a cylindrical lateral surface, and the conical roller last mentioned tapering in the direction of the other longitudinal edge of the band, or the rotational axis of the deflection roller having a cylindrical lateral surface spatially approaching the rotational axis of the conical roller arranged downstream in the running direction of the band on the edge side of the band opposing the longitudinal edge to be joined.
