A method for cleaning a paint spray gun, which comprises a rotating atomization head to apply a coating material while rotating and an outer circumferential tube to cover the exterior of the rotating atomization head, has a cleaning solution application step for applying a cleaning solution to the external face of the outer circumferential tube, and a rotating atomization head rotation step for generating a rotational flow between the rotating atomization head and the outer circumferential tube by rotating the rotating atomization head. The cleaning solution flowing down the external face of the outer circumferential tube applied in the cleaning solution application step penetrates between the rotating atomization head 5 and the outer circumferential tube by way of the rotational flow. Such method uses a small amount of cleaning solution for cleaning external and internal faces of the outer circumferential tube and the external face of a rotating atomization head.

A liquid processing apparatus includes a processing liquid supply including a nozzle configured to discharge a processing liquid; a nozzle mover configured to move the nozzle between a coating position and a standby position; a suction unit including a suction opening toward a leading end surface of the nozzle located at the standby position; a cleaning unit configured to clean the leading end surface of the nozzle located at the standby position with a cleaning liquid; and a control device. The control device controls the processing liquid supply to discharge the processing liquid in a state that the nozzle is located at the standby position. The control device controls the suction unit to suck the processing liquid. The control device controls the cleaning unit to supply the cleaning liquid toward the standby position to clean the nozzle. The control device controls the suction unit to suck the cleaning liquid.

A contact nozzle for simultaneously coating a plurality of elastic strands moving in a machine direction with an adhesive is described. The contact nozzle includes a single fluid inlet for receiving the adhesive from a fluid module, a first inverted V-shaped notch, a second inverted V-shaped notch, a third inverted V-shaped notch, and a mounting surface configured to abut the fluid module when the contact nozzle is coupled to the fluid module. Each inverted V-shaped notch extends along the contact nozzle in the machine direction, has an open bottom end, a circular closed top end. Each inverted V-shaped notch includes an adhesive orifice in fluid communication with the single fluid inlet for receiving the adhesive for directing the adhesive into contact with an upper surface of an elastic strand.

The apparatus can include a water inlet, a control unit, a control unit switch, and a control unit outlet; a reservoir dispenser having a chamber, a reservoir dispenser switch, a reservoir dispenser valve, a reservoir dispenser outlet, and one or more lids or caps having a built-in check valve on the one or more reservoir dispensers; a nozzle assembly having a washing nozzle, connected to the control unit outlet with a water tube, a protective .shield gate covering the nozzle assembly and washing nozzle; and a plurality of nozzle assembly and/or gate cleaning outlets connected to the reservoir dispenser outlet with a water tube tor cleaning and/or disinfecting the nozzle assembly, washing nozzle, and/or the protective gate.

Embodiments of the invention provide a push valve assembly. The push valve assembly includes a valve piston that is movable within a valve body between a fully opened position and a fully closed position, passing through an intermediate rinsing position, to selectively provide pressurized fluid through flow paths defined by the position of the valve piston.

A nozzle cleaning apparatus has one cleaning liquid outlet to which a nozzle is attached, and the other cleaning liquid outlet to which a cleaning attachment is attached. The cleaning attachment includes a nozzle cover, and a cleaning holder attached to the nozzle cover. A cleaning chamber is formed in the nozzle cover. A cleaning liquid inflow chamber, an outer cleaning liquid ejection port, and a cleaning liquid discharge hole are formed in the cleaning holder. A cleaning liquid ejected in a first direction from the nozzle and a cleaning liquid ejected in a second direction from the outer cleaning liquid ejection portion toward the nozzle collide with each other near discharge portions inside the cleaning chamber.
