A joint and device for joining ends of at least two fiber webs together, the joint being formed of at least one cut provided to penetrate through the ends of the fiber webs in an overlapping position, which cut has at least one side part and from the side part extending at least one substantially straight part and which cut, which forms at least one flap, being configured to remain attached to the fiber webs by at least one folding line substantially aligned with the direction of the movement of the fiber webs. The device comprises a tool with a cutting edge and a counter element with a groove and located on the opposite side of the fiber webs, and the tool protrudes into the groove. The groove has a greater cross-sectional area than the cross-sectional area of the tool such that a loose and spacey fitting is provided.

A method for joining ends of fiber webs with a device comprising a tool element with a gripping device and a traversing punching device. A run of the fiber web from the emptying parent roll is moved to a joining position at the tool element. The trailing end of the parent roll fiber web is cut upstream from the joining position and the fiber web is attached to the tool element by a gripping device of the tool element. An end of a new roll fiber web is guided to contact with and to an overlapping position with the trailing end of the parent roll fiber. The traversing punching device is moved across the width direction of the fiber webs and makes at least one joint cut and joins the fiber webs. The new fiber web is cut downstream from the joint, and then tension control is turned on.

A vacuum station comprising a main housing and a pair of arms extending from the main housing. The arms are configured to hold a roller. The main housing has a front face and a rear face, with the front face having a recess therein. An air path extends from the front face to the rear face. The vacuum station also includes a removable plate having a plurality of suction holes therethrough located within the recess in the front face of the main housing. The removable plate is removably connected to the main housing by magnets. A sheet of labels can be held to the removable plate by a suction force through the air path in the main housing and the suction holes in the removable plate.

An assembly comprises a device for producing a corrugated board web laminated on one side comprising a fluting device for fluting a first material web and a pressing device for pressing the glued corrugated web and a second material web against one another. The assembly comprises a first transverse position detecting device, upstream the fluting device, for detecting the first material web, a second transverse position detecting device, upstream the pressing device, for detecting the second material web and a signal processing unit, which is capable of actuating a unrolling device for unrolling the second material web so that in the device for producing a corrugated board web it is transversally displaced correspondingly.
