Abstract: A method and device for carrying out a reel splice to avoid the fluttering of tails makes it possible to allow the tail to also adhere across its entire length, in particular on a web with high mechanical strength. When using a fluid-repelling substrate, an adhesive-free liquid is applied to a new roll and/or to at least a portion of the side of the tail facing the web. The method and device can be used in reel splicers which process fluid-repellent substrates, such as for example plastic films, metal films or laminated laminates, so that a sticking out or fluttering of the tail is avoided.

Abstract: A webbing apron of a device for webbing up a printing substrate web in a printing press, namely a web-fed printing press, is disclosed. The webbing apron includes a cable, which is used for engagement of a tension element that is embodied in particular as a chain, and a flat element, where the flat element wraps around the cable at least in sections and is connected to the cable. The flat element is embodied of fluorinated rubber and the cable is permanently connected to the flat element made of fluorinated rubber by vulcanization.

Abstract: To sense misalignment between a clamping mandrel (1, 2) of a web roll carrier and a web center sleeve or tube (5) into which the mandrel is to be inserted, the mandrel is formed with a sensing head (8, 10, 11, 14) which is spring-loaded and projects by a distance (a) beyond an end face (9) of the tip portion (3) of the mandrel. Upon engagement of the sensing head, for example due to misalignment, with the sleeve or end face of the roll, the sensing head can resiliently slide into the mandrel and, at the same time, by coupling to an electrical switch pin (19), cause engagement of the switch pin with terminal rings (18, 19) located in the mandrel body, to cause reversal of movement of the mandrel from a forward or inserting movement (F) to reverse or retract (R) the mandrel, thus effectively and simply eliminating damage to the sleeve or tube and/or the roll of web material, and/or the mandrel.
