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 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.

The sealing device includes a heatable base plate that cooperates with a heatable split plate to simultaneously form three intersecting seal lines. The split plate includes an alpha plate and a beta plate. The alpha plate and the beta plate each include a first heated surface that cooperate with the base heated surface to form a pair of co-linear seal lines. In addition, the alpha plate and the beta plate each include a second heated surface that cooperate together to form a third seal line that extends in a direction perpendicular to the co-linear seal lines and intersects the co-linear seal lines. A method of forming a complex seal joint is also described.

The invention relates to an ultrasonic welding device comprising a sonotrode (14) transmitting ultrasonic vibrations and an anvil (15) disposed on an anvil carrier (17), the anvil (15) being disposed on the anvil carrier (17) in an exchangeable manner so that an mounting surface (21) of the anvil (15) rests against a support surface (22) of the anvil carrier (17) by means of a normal force exerted by a pretensioning device, the mounting surface (21) of the anvil (15) having a surface hardness greater than the surface hardness of the support surface (22) of the anvil carrier (17), the mounting surface (21) having a surface structure at least in the area of a partial surface, and the mounting surface (21) having a surface roughness of R.sub.z/R.sub.a≥2 at least in the area of the partial surface.

A method for manufacturing at least one elastomeric article is provided. The method includes placing into a mold an assembly of an uncured elastomeric sheet, a first film fully covering the elastomeric sheet and a second film covering the first film, such that the second film is in contact with and positioned between the first film and an interior surface of the mold. The method further includes curing the assembly in the mold, such that the first film is laminated onto the elastomeric sheet thereby forming the at least one elastomeric article.

A sonotrode includes multiple layers of a material melted to one another to form a structure. The structure provides a base that has an attachment feature that is configured to operatively secure to an ultrasonic converter. The structure includes a shaft that extends from the base to a terminal end that provides a working surface that is configured to selectively engage a workpiece.

It is provided an electronic control device including a resin molded body, a metal body, and an electronic component, wherein the resin molded body and a main surface of the metal body are bonded, and at least a part of a side surface continuous to the main surface of the metal body is in contact with a side contact portion provided in the resin molded body.

Provided are a metal clad laminate and a method for producing the same. The metal clad laminate at least includes a thermoplastic liquid crystal polymer film and a metal sheet bonded to each other, wherein the thermoplastic liquid crystal polymer film has a surface with a glossiness (20) of 55 or higher in accordance with JIS Z 8741 on the opposite side of the bonding surface to the metal sheet. The method for producing a metal clad laminate at least includes: providing a thermoplastic liquid crystal polymer film 2 and a metal sheet 6; and introducing the thermoplastic liquid crystal polymer film 2 and the metal sheet 6 between a pair of heating rolls so as to laminate them.
