A static mixer is disclosed. The static mixer comprises a housing (22) defining an internal mixing cavity (36) that longitudinally extends along a central axis between an inlet (38) and an outlet (40) and is adapted for axial flow of a fluid therethrough. The static mixer also comprises a mixing element (42) disposed within the mixing cavity (36). The mixing element (42) is configured to be free from an impingement surface oriented substantially perpendicular to a main direction of fluid flow through the internal mixing cavity (36). The mixing element (42) comprises an elongated mixing blade that is oriented longitudinally within the mixing cavity (36) and comprises a nose axially oriented toward the inlet (38). The static mixer may comprise a heat-exchanging jacket integrally formed with the housing (22). An additive manufacturing system comprising the static mixer, and methods of making and using the same, are also disclosed.

An apparatus and method for application of a line of resin along a crease line of a garment for increasing the life of the crease line. The apparatus in one embodiment allows a simultaneous application of lines of resin along respective crease lines of one or more garments to provide an increase in productivity. The apparatus and method allows the operation of a source of a pressurised fluid source used in dispensing of the resin from one or more cartridges held on mounting apparatus to be achieved by an operator's hand which, at the same time, is used to hold gripping portion on the mounting apparatus to move the cartridges and mounting apparatus with respect to the crease line to apply the resin.

A robot end effector (100) for dispensing an extrudable substance (102) comprises a chassis (110), a static mixer (101), and cartridge bays (122), extending from the chassis (110). Each of the cartridge bays (122) is shaped to receive a corresponding one of the two-part cartridges (104). Fluidic communication between the selected one of the two-part cartridges (104) and the static mixer (101) is established when the cartridge bays (122) are rotated about an axis (190) to a predetermined orientation with respect to the chassis (110). The robot end effector (100) also comprises a dispensing valve (130), attached to the chassis (110), and a head assembly (150), comprising an inlet manifold (152). The inlet manifold (152) is configured to selectively supply compressed air from a pressure source (199) to contents of a corresponding one of the two-part cartridges (104).

A mixing tip for mixing multi-component materials exiting a multi-component cartridge includes a code that is stored in or at the mixing tip indicating at least one of a type of mixing tip, a manufacturer of the mixing tip, a date of production of the mixing tip and a list of materials compliant with the mixing tip.

A valve including a feed mechanism, a mixing element operably connected to the feed mechanism, wherein the feed mechanism delivers at least two fluids to the mixing element, the at least two fluids being mixed in the mixing element, and an air cap disposed proximate an outlet of the mixing element to atomize the mixed fluids exiting the outlet of the mixing element, is provided. Furthermore, an associated method is also provided.

A dynamic mixer for mixing a multi-component material includes a mixing rotor capable of being rotated about an axis of rotation, the mixing rotor having a coupling socket configured at an end thereof. The coupling socket has a reception space configured to receive at least a part of a polygonal shaped coupling plug of a drive shaft to transfer torque from the drive shaft to the mixing rotor. The reception space has an inner length in the direction of the axis of rotation and has an inner surface extending over the inner length and surrounding the axis of rotation.

A container with two inner chambers (6, 7) running in its longitudinal direction and separated by at least one partition wall. An aerobic adhesive is stored in one inner chamber (6). A hydrophilic, gel-like activator is stored in the other inner chamber (7); a mixing unit can be attached to the front end of the container. The aerobic adhesive is fed to the mixing unit from the first inner chamber (6), and the hydrophilic activator is fed to the mixing unit from the second inner chamber (7), in a specified mixing ratio via a supply device and mixed together there. This mixture is discharged via an outlet opening (13) of the mixing unit.

A valve including a feed mechanism, a mixing element operably connected to the feed mechanism, wherein the feed mechanism delivers at least two fluids to the mixing element, the at least two fluids being mixed in the mixing element, and an air cap disposed proximate an outlet of the mixing element to atomize the mixed fluids exiting the outlet of the mixing element, is provided. Furthermore, an associated method is also provided.

The disclosure relates to an application device for multi-component substances, in particular multi-component adhesives or multi-component sealants, including: at least two cartridge receiving devices for receiving replaceable cartridges with substance components that are to be mixed; a discharging device for discharging the substance components from the cartridges; a mixing device for mixing the substance components, wherein the mixing device includes a rotary mixer which is driven via a drive shaft, the drive shaft having at least one flexible portion with a first end and a second end.

A dispensing apparatus simultaneous discharges at least two flowable components of a multi-component mass from different storage volumes. The dispensing apparatus includes a passive mixing unit having a central mixing passage extending along a flow direction and being configured to guide the components mixed with one another, and including at least two inlets opening into the central mixing passage, the inlets being associated with the same storage volume and open into the mixing passage at different positions along the flow direction.
