A method of producing a golf ball applies ultrasonic welding on two half shells to form at least one intermediate layer, at least one cover layer, or at least one intermediate layer and at least one cover layer. The ultrasonic welding may include pressing the two half shells together, delivering a high power electrical signal to a welding stack, and converting the high power electrical signal at the welding stack to ultrasonic energy. The converting may include converting the high power electrical signal into a mechanical vibration, modifying an amplitude of the mechanical vibration to generate a modified mechanical vibration, and applying the modified mechanical vibration to an interface of the two half shells to weld them together ultrasonically. Aspects also relate to golf balls, or one or more layers thereof, made using ultrasonic welding.

An ultrasonic processing system (1) which comprises an ultrasonic vibrator (10) having an ultrasonic sonotrode (30) and a working surface (31) for ultrasonic processing of a workpiece. The vibrator (10) comprises a longitudinal axis (L), an enclosed cavity (32, 51) extends along the longitudinal axis at least in the sonotrode (30), a medium inlet (52) through which a cooling medium is fed into the cavity (32, 51), at least one vortex generator (53) which arranged between the medium inlet (52) and the cavity (32, 51) such that a swirl motion of the medium is generated inside the cavity (32, 51) around the longitudinal axis. A cooling channel (34) is fluidly connected to the enclosed cavity (32, 51) to guide the medium in the vicinity of the working surface (31) such that the working surface (31) is cooled. A first medium outlet (33) is fluidly connected to the cooling channel (34).

A protective packaging formation device is disclosed herein. The device includes an inflation assembly that directs fluid between first and second overlapping plies of a web material. The device also includes a sealing mechanism that includes an arcuate web-support surface. The web-support surface includes a heater that defines a heating zone that is operable to heat the plies to create a longitudinal heat seal that seals the first and second plies together as the web is driven over the heating zone in a downstream direction. The web-support surface also includes a cooling zone disposed downstream of the heating zone operable to allow the heated plies to cool at the longitudinal heat seal as the web is driven over the heating zone in a downstream direction, such that the cooled longitudinal heat seal retains the fluid between the plies.

The present invention relates to a self-punching functional element that is adapted for punching into a workpiece, in particular into a sheet metal part. It comprises a head part forming a flange and having a contact surface for contact with the workpiece; and a punching section that extends away from the head part, in particular from the contact surface, and that is in particular arranged coaxially to a central longitudinal axis of the functional element. The punching section has a peripheral punching edge at its free end for punching through the workpiece and surrounds a cavity in a peripheral direction, said cavity having an opening defined by the punching edge. An inner wall of the punching section facing the cavity has at least one elevated slug securing portion projecting radially inwardly into the cavity, in particular wherein the elevated portion has the form of a rib extending in an axial direction.

An apparatus to join two panels together includes a chamber, a horn positioned within the chamber, the horn moving reciprocally within the chamber, and a set of heating elements positioned about the horn to heat the horn. One of the panels has a post molded to it, the post extending through the other panel, and after the horn is heated an end of the horn is placed on top of the post and is ultrasonically vibrated to form a head of the post to join the two panels together.

A microfluidic cartridge, configured to facilitate processing and detection of nucleic acids, comprising: a top layer comprising a set of cartridge-aligning indentations, a set of sample port-reagent port pairs, a shared fluid port, a vent region, a heating region, and a set of Detection chambers; an intermediate substrate, coupled to the top layer comprising a waste chamber; an elastomeric layer, partially situated on the intermediate substrate; and a set of fluidic pathways, each formed by at least a portion of the top layer and a portion of the elastomeric layer, wherein each fluidic pathway is fluidically coupled to a sample port-reagent port pair, the shared fluid port, and a Detection chamber, comprises a turnabout portion passing through the heating region, and is configured to be occluded upon deformation of the elastomeric layer, to transfer a waste fluid to the waste chamber, and to pass through the vent region.

The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatuses may include a pattern roll including a pattern element protruding radially outward. The pattern element includes a pattern surface and includes one or more channels adjacent the pattern surface. The pattern roll may be positioned adjacent an anvil roll to define a nip between the pattern surface and the anvil roll, wherein the pattern roll is biased toward the anvil roll to define a nip pressure between pattern surface and the anvil roll. As substrates advance between the pattern roll and anvil roll, the substrates are compressed between the anvil roll and the pattern surface to form a discrete bond region between the first and second substrates. As such, during the bonding process, some yielded substrate material flows from under the pattern surface and into the channel to form a channel grommet region.

A manufacturing apparatus of a display device includes a first jig configured to hold a first member; a second jig located under the first jig and coupled to or separated from the first jig such that the first member is locatable between the first jig and the second jig; fixing parts located at both ends of the second jig and configured to hold a second member between the first member and the second jig, the second jig including a pad; and a stage located under the pad and provided with a groove formed therethrough and having an area smaller than an area of the pad when viewed in a plan view, wherein one portion of the pad, which faces the stage, is configured to be within the groove.

The present disclosure is directed to a compression belt for inflation and sealing devices. The device may include an inflation assembly, a heating assembly, and a drive mechanism. The inflation assembly may direct fluid between first and second overlapping plies of a flexible web material to inflate chambers between the plies. The heating assembly may be operable to heat the first and second plies of the web material to create a longitudinal heat seal that seals the fluid in the inflated chambers. The drive mechanism may drive the web material in a downstream direction. The drive mechanism may tension the web material against the heating assembly. The drive mechanism may include a first belt including a high grip material on a surface that contacts the web material to grip the web material during heating by the heating assembly.
