Apparatus for applying tear strips to wrappers
Abstract
Abstract Apparatus for applying a tear strip or the like to a wrapper web comprises a sun gear about which a planet carrier is rotated. A first planet gear meshed with the sun gear and also with a second planet gear, both being mounted on the planet carrier. A suction wheel is eccentrically mounted on the second planet gear, which results in the suction wheel rotating about the axis of the second planet gear and a the same time traversing a substantially rectilinear polygonal path as the planet carrier is rotated. A device for cutting tear strips or the like from a web is positioned adjacent to one side of the polygonal path and as the suction wheel moves along this side the tear strip is wound on to the suction wheel. The wrapper web is guided over a platform, having a resilient covering, and has a line of adhesive applied to it. The platform is positioned adjacent to a different side of the polygonal path and while the suction wheel is traversing this side the tear strip contacts the adhesive and is unwound from the suction wheel and deposited on to the wrapper web.
