A device for applying viscous material to workpieces includes a rotary lance in a holder apparatus and rotatable about a longitudinally-extending rotation axis, the lance having at least one material outlet. A needle valve associated with each material outlet has a longitudinally-extending valve needle used to close each material outlet on a valve seat. Each valve needle has an associated cylinder with a plunger chamber in which a plunger is movable by pressure applied by a fluid, the valve needle being permanently connected to the plunger. A tappet is connected to each plunger, the tappet, at its upper end facing away from the at least one valve seat, being sealingly guided out of the associated plunger chamber. The rotary lance has a measuring element which can be acted upon by the tappet and moved longitudinally; and the holder apparatus has a sensor for determining the measuring element position.

This installation for application of a coating product comprises a print head equipped with a plurality of nozzles each controlled by a valve supplied by a product source. A product accumulator, installed on a product circulation circuit, comprises a deformable or movable wall delimiting, at least in part, a first chamber of variable volume supplied with coating product and a second variable-volume chamber supplied with gas, under a predetermined pressure equal to a nominal operating pressure of the print head. The first chamber of variable volume is supplied or purged with coating product due to a difference between an instantaneous coating product ejection rate from the print head and a supply rate to the print head from the source. A control unit adjusts an operation setpoint value of the source as a function of the difference between instantaneous ejection flow rate and supply flow rate, to reduce this difference.

A nozzle arrangement applies fluids, in particular thermoplastic adhesives, to a substrate. The nozzle arrangement and the substrate move relative to one another in a first direction. The nozzle arrangement has a main body which is exchangeably connected to a mounting region of a distributor and which has an end-side side surface extending in a second direction running at least substantially perpendicular to the first direction.
