VACUUM COATING DEVICE FOR FLEXIBLE SUBSTRATE
A vacuum coating device for a flexible substrate is provided, including a vacuum coating chamber and a transition chamber which are connected to each other. The vacuum coating chamber and the transition chamber communicate with each other through a slit. The vacuum coating device further includes a cooling roller, which is fixed in the transition chamber through a tension adjusting component. The cooling roller includes a roller body and a shaft, the roller body is fixedly installed on the shaft, and the roller body and the shaft are coaxial. Multiple heat dissipation passages are provided in the roller body along an axial direction of the roller body. Good cooling function is achieved and the flexible substrate is prevented from generating winkles.
MACHINE ARRANGEMENT FOR SEQUENTIAL PROCESSING OF SHEET-TYPE SUBSTRATES
A machine arrangement, for sequentially processing sheet-type substrates, includes a plurality of different processing stations, one of which includes a non-impact printing device that prints the substrates. The processing station, including the non-impact printing device, also includes a printing cylinder, on the circumference of which, the non-impact printing device that prints the substrates is arranged. On the circumferential surface of the printing cylinder, four substrates are or can be placed behind each other in the circumferential direction. Each of the substrates that are to be conveyed are retained in one of a force-locking and a form-fitting manner on the circumferential surface of the printing cylinder by at least one retaining element.

Machine arrangement with printing unit for the sequential processing of sheet-type substrates
A machine arrangement sequentially processes sheet-like substrates with multiple different processing stations each having a substrate-guiding unit and a substrate-processing unit. At least one of the processing stations has, as a substrate-processing unit, at least one non-impact printing device which prints on the substrate. The processing station with the at least one non-impact printing device has a printing cylinder. Each non-impact printing device is arranged at the circumference of the printing cylinder. The printing cylinder is triple-sized or quadruple-sized. A double-sized or a triple-sized transfer drum, or a corresponding feed cylinder, is arranged directly upstream of this printing cylinder. Alternatively, a double-sized or a triple-sized transfer drum, or a corresponding transfer cylinder, is arranged directly downstream of this printing cylinder.

Preventing the fluttering of the tail in film printing
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.
