Abstract: The invention relates to a device for cutting off and guiding an edge strip from one part of a paper or board machine to another in connection with the threading of a paper or board web. The device includes air jet nozzles for guiding the edge strip, and a threading plate which is provided with a cutting mechanism for cutting off the edge strip. In order to provide a device reliable in operation, the cutting mechanism including at least one blade member which is arranged to be displaced during the cutting of the edge strip in a plane substantially parallel to the plane of the threading plate from the front side of the threading plate towards the front edge thereof and to cut off the edge strip on the side facing away from the front edge of the threading plate and to guide the edge strip further on to the threading plate.

Abstract: The invention relates to a device for displacing a reeling drum of a web-like material from a store on a primary fork of the reeler of a paper machine or the like. The device comprises a displacing arm mechanism mounted pivotably around a stationary horizontal shaft and arranged to grip an empty reeling drum positioned in the store in an upper position and to deliver the reeling drum in a lower position on the primary fork. In order to provide a simple device reliable in operation and easy to automate, the displacing mechanism comprises a lever and a hook. The hook is journalled displaceably on a journal point provided in the lever so as to be displaced during the pivoting movement of the displacing mechanism.
