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 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.

摘要： A support for one or more rolls of sheet stock material includes a sloped support surface for supporting at least one roll, an operating stop toward a lower end of the support surface that defines an operating position at which a stock roll is held for paying out sheet stock material from the roll, and a holding stop. The holding stop extends above the support surface. The holding stop holds one or more rolls at a location spaced from the operating position, and is movable to allow a stock roll to move down the support surface, past the holding stop to the operating position.
