Abstract: A sealing arrangement having a rod seal for sealing a cavity for a flowable medium in the region of a rod includes an output apparatus for discharging the flowable medium. The rod is movably supported in a housing to be displaced in an axial direction. The housing has a bearing portion, wherein the rod seal is supported in a fixed manner and wherein the rod extends through the bearing portion and the rod seal so that a first rod portion and a second rod portion are arranged at different sides of the bearing portion. The first rod portion is located at a side facing the cavity and the second rod portion is located at a side facing away from the cavity. The rod seal is arranged at the side of the bearing portion facing the first rod portion and has a first sealing lip and a second sealing lip that are spaced apart from each other in the axial direction and circumferentially contact the rod.

Abstract: A fastening system for fastening an article to a heating hose, a corresponding heating hose and an application system having a corresponding fastening system. The fastening system is provided for a holder of the fastening system to be fastened magnetically to an end cap of the heating hose.
Abstract: A heated hose for passage of a free-flowing medium, for example for the passage of a hot-melt adhesive. The heated hose has an angled attachment piece, wherein the attachment piece has a first limb and, angled with respect to the first limb, a second limb, wherein the attachment piece has a through-channel which runs through the limbs to allow the free-flowing medium to pass through the attachment piece, and wherein the attachment piece has a coupling connector for producing a fluidic connection between the heated hose and an external apparatus, by coupling the external apparatus along a coupling axis of the coupling connector.

Abstract: A melter for preparing a molten medium, in particular for preparing a molten adhesive, has a melting tank that has a melting chamber for receiving and melting a medium to be melted. The melter has a heating device for heating the melting chamber. The melting chamber has an upper chamber section and a lower chamber section. The melting tank has a dispensing opening that can be fluidly connected to a delivery device for delivering the molten medium. The melting tank further has a drain opening. The dispensing opening and the drain opening open into the lower chamber section. The melter further has a closure body for closing the drain opening. In a closed position, the closure body closes the drain opening and an end section of the closure body projects into the lower chamber section.
