In one example, an adhesive dispensing assembly has a dispenser and an air supply assembly. The dispenser receives a liquid material therein and discharges the liquid material onto a substrate. The air supply assembly receives pressurized air therein and directs the pressurized air to the dispenser to cause discharging of the liquid material from the dispenser. The dispenser has a first coupler, and the air supply assembly has a second coupler that couples to the first coupler so as to positionally fix the dispenser and the air supply assembly to one another. At least one of the first and second couplers is formed from a thermally insulating material that thermally insulates the dispenser and the air supply assembly from one another when the first and second couplers are coupled to one another.

Performance solenoid assembly

An air manifold for a material dispensing applicator is described. The air manifold has an inlet to receive pressurized air from a pressurized air source, a channel extending therethrough from the inlet, and a plurality of passages in fluid communication with the channel. The air manifold also includes a plurality of pneumatic bolts, where each of the plurality of pneumatic bolts is disposed in a respective one of the plurality of passages and attached to a respective one of the plurality of dispensing modules of the applicator. Each of the plurality of pneumatic bolts directs the pressurized air from the channel of the air manifold to the respective one of the plurality of dispensing modules.

Connector for a material dispensing assembly

An adhesive dispensing system for applying liquid adhesive to a substrate using different nozzles with the same manifold is disclosed. The adhesive dispensing system includes a manifold having a body, a first clamp configured to engage the body of the manifold, a second clamp configured to engage the body of the manifold, and a nozzle. The first and second clamps secure the nozzle to the body of the manifold. The body of the manifold has a first contact surface that engages the first clamp and a second contact surface that engages the second clamp and the nozzle, where the second contact surface is angularly offset from the first contact surface.

Adhesive dispensing system with convertible nozzle assemblies

A method for controlling a recirculation pump assembly is disclosed. The method includes receiving a process-dependent characteristic and determining a recirculation flow rate of adhesive that flows to the recirculation pump assembly based on the process-dependent characteristic. The method further includes determining a recirculation pump speed of the recirculation pump assembly for pumping the adhesive to a supply channel using the recirculation flow rate, and adjusting an operating speed of the recirculation pump assembly to match the recirculation pump speed. A system and storage device for performing the above method are also disclosed.

System and method for active adhesive recirculation control

An applicator for dispensing adhesive onto a substrate is described. The applicator includes a manifold and at least one dispensing module coupled to the manifold. The applicator may include a least one pump assembly removably mounted to the manifold. Each pump assembly can have an outlet in flow communication with the manifold, and an inlet in flow communication with the adhesive. The use of a removable, independently controllable pump assembly can provide an operator of the applicator greater flexibility during adhesive dispensing.

Applicator with at least one pump having an integrated drive

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.

System, nozzle and method for coating elastic strands

The present disclosure describes a method and system for controlling dispensing of adhesive from an applicator. The method includes pumping adhesive from a plurality of pump assemblies to a plurality of dispensing modules and measuring current draw from each of the plurality of pump assemblies. The method also includes determining an adjustment to an operating speed of each of the plurality of pump assemblies individually based on their respective current draws and adjusting the operating speed of each of the plurality of pump assemblies individually.

Applicator having active backpressure control devices

An applicator for dispensing multiple adhesives on a substrate is disclosed. The applicator includes a manifold that includes a first dispensing module and a second dispensing module. The first dispensing module has a first inlet and a first nozzle. The first inlet receives a first adhesive and the first nozzle applies the first adhesive to the substrate. The second dispensing module is adjacent the first dispensing module and has a second inlet and a second nozzle. The second inlet receives a second adhesive that is different from the first adhesive. The second nozzle applies the second adhesive to the substrate.

Applicator with diverter plate

A remote metering station for pumping a flow of adhesive to a dispensing module is disclosed. The remote metering station includes a manifold having a front surface, a back surface opposite to the front surface, a first side surface, a second side surface opposite the first side surface, a top surface, and a bottom surface opposite to said top surface. The remote metering station also includes a modular pump assembly removably mounted to the manifold, where the modular pump assembly includes a bottom surface, an outlet on the bottom surface, the outlet being in fluid communication with the manifold, and an inlet for receiving the adhesive. The modular pump assembly further includes a gear assembly and a drive motor coupled to the gear assembly. The gear assembly is operable for pumping the adhesive from the inlet to the outlet.

Remote metering station

An applicator for dispensing adhesive is disclosed. The applicator includes a manifold, at least one dispensing module coupled to the manifold, a supply channel configured to contain at least a portion of the adhesive, a recirculation channel configured to contain at least a portion of the adhesive, and a recirculation pump assembly connected to the manifold. The recirculation pump assembly includes an inlet in fluid communication with the recirculation channel, an outlet in fluid communication with the supply channel, a gear assembly, and a drive motor coupled to the gear assembly and operable to pump the adhesive, where the drive motor is configured to operate at an adjustable number of revolutions per minute (RPM). The recirculation pump assembly can be configured to move at least a portion of the adhesive from the recirculation channel to the supply channel, such that a first pressure of the adhesive in the recirculation channel is substantially equal to a second pressure of the adhesive in the supply channel.
