A method for joining composite rods with tubular shape without expensive, machined connectors and without compromising the structural integrity of the composite rod includes internal and external collars applied to the ends of the composite rod and deformed via unidirectional compressive load applied by a clamp in the radial direction of the composite rod cross-section. The resulting plastic deformation of the metal collars and composite rod interlock those components to support both compressive and tensile loads. The deformed metal collars are easily joinable to other components via off-the-shelf hardware.

A method for joining at least two joining partners includes performing a plurality of ultrasonic joining operations in direct succession, wherein performing an individual ultrasonic joining operation includes, with a second joining tool, applying pressure to a second joining partner arranged adjacent to a first joining partner, thereby pressing the second joining partner against the first joining partner, and, with the second joining tool, applying high-frequency ultrasonic vibrations to the joining partners. The method further includes, during at least one intermediate time interval between two directly successive ultrasonic joining operations, at least one of actively cooling and heating the second joining tool. The second joining tool is heated or cooled by a temperature unit. The temperature unit is inactive during each of the plurality of ultrasonic joining operations.

The invention concerns a manufacturing process for producing hermetic single-use food containers, including: forming a container body (30) having an peripheral rim (31), placing the container body in a sealing head having a first die (2) and a second die (8) having cooperating annular sealing surfaces (4, 10) facing the rim (31), sealing a closing lid (34) placed over the container body with the rim (31) by applying the first die (2) and the second die (8) one against the other. According to the invention, the first die (2) is provided with a continuous annular rib (6) in its sealing surface (4), the rib having a height (h) which is at least equal to a maximum depth of wrinkles that might appear on the rim upon forming the container body, whereby a sealing groove (12) is formed by the rib (6) in a side of the rim during the sealing.

A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have connected thereto, a source of power that is an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire ay be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones ma include temperature zones, cartridge heaters, cooling air, or hated air, or a source of ultrasonic, microwave or radiative energy.

A method for automatically replacing reels in an unwinding assembly capable of carrying out the handling operations of the reels, as well as preparing and joining the tail of the web of the finished reel with the head of the web of the new reel in a simple, efficient way, reducing the risk of malfunctions and maintaining the correct orientation of the new web as that of the finished web.

An applicator mitt assembly system comprises an applicator mitt tooling including: a tooling body having a mitt-perimeter cutter and weld bead thereon which are shaped to a perimeter of a mitt to be cut; a heating element associated with the tooling body which is shaped so as to substantially match a shape of the weld bead to create a perimeter weld for the mitt when engaged with the tooling body; and an ejector platen which is actuatable relative to the tooling body to eject a cut and welded mitt. A conveyor device is adapted to feed mitt material towards the tooling and a tooling actuator adapted to actuate the tooling relative to the conveyor device to allow the cutter to cut mitt material at the conveyor device. A discrete applicator mitt tooling, method of assembling an applicator mitt, and welded applicator mitt are also provided.

Manufacturing capsules, comprising preparing a first and a second capsule element, at least the first element containing a cavity, each element, being provided with a peripheral ring, bringing the elements together, so that the rings are superimposed, placing the two elements between a sonotrode and an anvil, the anvil containing an anvil recess and a striking surface, surrounding the anvil recess, the sonotrode including a sonotrode recess, with the same cross-section as the anvil recess, and a working surface surrounding the sonotrode recess, wherein the striking and working surfaces are configures to come into contact with each other on a working area, extending around the recesses, clamping the rings between the working surface and the striking surface by the proximity of a sonotrode and the anvil, activating the sonotrode and directing the ultrasound towards the anvil, whilst maintaining the clamping action, wherein the rings are detached from the capsule.

Dispensing devices can include buffers. This obviates the need for continually pumping the device to dispense spray or foam. A buffer can be spring loaded, spring loaded combination, elastomeric or gas, and can be in line or adjacent to a piston chamber. Such sprayers and foamers can be mounted upside down. With a buffer, a piston chamber can deliver a greater amount of liquid per unit time than can be dispensed through the nozzle(s). The fraction of liquid that cannot be dispensed can be sent to the buffer for dispensing after the piston downstroke has completed. Volume of the piston chamber and buffer, pressure response of the buffer, throughput of the nozzle, and the minimum opening pressure of the outlet valve can be arranged to restrict the outlet pressures of liquid droplets exiting the nozzle within a defined range.

The invention relates to a device comprising a first fixing element, a further fixing element and a folded planar composite; wherein the first fixing element comprises a first fixing surface and the further fixing element comprises a further fixing surface; wherein the folded planar composite is at least partially fixed between the first fixing surface and the further fixing surface; wherein the folded planar composite comprises a first composite region; wherein the first composite region comprises a first layer sequence comprising a first composite layer comprising a first carrier layer, a second composite layer comprising a second carrier layer, a third composite layer comprising a third carrier layer and a fourth composite layer comprising a fourth carrier layer; wherein in the first composite region the second composite layer is joined to the third composite layer and the third composite layer is joined to the fourth composite layer; wherein in the first composite region the third carrier layer is characterised by a smaller layer thickness than in each case one selected from the group consisting of the first carrier layer, the second carrier layer and the fourth carrier layer or a combination of at least two of these; wherein the first fixing surface or the further fixing surface or both comprises a recess comprising a first recess region; wherein the first composite region is located at least partially between the first recess region and the first fixing surface or the further fixing surface.
