摘要： 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.

摘要： 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.

摘要： A splice tape is provided. The splice tape includes two internal support layers bonded at interface between opposing inner surfaces of the internal support layers. The support layers are formed utilizing a process and/or materials that ensure that the two internal support layers separate cleanly and consistently along the interface of the two internal support layers.

摘要： A web handling system and method for controlling tension in a web of material is disclosed. For instance, the web handling system is particularly well suited for maintaining web tension within predefined setpoints during temporary interruptions in the process, such as during splicing operations. The web handling system includes an accumulator or festoon that accumulates amounts of the material as the material is being fed downstream. At least one guide roll within the festoon is coupled to a drive device, such as a motor. The system also includes at least one tension sensing device. The drive device accelerates or decelerates the guide roll based upon information obtained from the tension sensing device. In one embodiment, the system further includes an electronic gearing configuration between a roll of material being unwound and the guide roll within the festoon for better synchronization and further minimizing tension swings. The electronic gearing can include a diameter calculator for the roll of material being unwound based on speed feedback of a driven guide roll.
