Abstract: An ink bar is provided with a control device for bringing back printing ink into the ink duct (20) of a printing machine when required. The aim of the invention is to arrange all the essential function pieces in a space-saving manner, whereby said pieces are used for adjusting the ink level. The ink bar (1) is made from a hollow rod prifile having an undercut groove (4) on the lateral outer wall. Said groove serves for receiving cables (5). Discharge valves (8) and the supply device of an ink valve are arranged in the inner chamber of the rod profile. The ink valve is coupled to a sensor (9) and said valves are connected by means of the cable (5).

Abstract: An adhesive tape pack, in which an adhesive layer (3), preferably a hot-melt adhesive layer, is arranged on at least one carrier element (2). In order to provide adhesive tape packs of this type with tape sections (5), which can be easily separated from one another, the present invention provides for providing the carrier element (2) with notches (4) transversely to the longitudinal direction of the tape, which cut through the carrier element (2), but not the adhesive layer (3). In this way, the tape sections (5) are held together by means of the adhesive layer (3) and can be separated by lightly cutting through the adhesive layer (3) along the notches (4).

Abstract: The present invention pertains to a treating device 1, especially a rotating transverse gluing mechanism for high-speed, register mark-related paper or film webs 2. The movements of the transverse gluing mechanism 1 are synchronized with the web 2, and the transverse gluing mechanism has an independent synchronous drive 6 with a drive motor 7 and a regulating unit for this purpose. The electronic regulating unit compensates variations in the synchronism of the running web 2.
