A hole cutter/punch arrangement that can be changed over quickly to a different hole cutter or punch or slitter, or can instead be converted to a sealer in manufacture of items from plastic film. A reciprocating drive such as an air cylinder is coupled to a transverse mount or holder, of a T-shaped profile and the punches and sealers each have a mounting shoe with a transverse T-profile channel to slide onto the mount where a detent holds the shoe releasably in place. A triple-tree arrangement of a center drive post and left and right guide posts connects to the transverse holder.

A heat-sealing apparatus for forming a composite heat seal structure, includes a belt conveying, heating and press bonding portion configured to convey and heat a heat seal material to form a band-shaped peelable seal, and a die roll press bonding portion configured to add a linear peelable seal to the band-shaped peelable seal in a longitudinal direction of the band-shaped peelable seal for forming the composite heat seal structure.

To provide a method for readily forming an easily separable portion having an adhesive strength that is required as a package bag on packaging film, a package bag having an easily separable portion formed by this method, and a filling-packing machine utilizing this method. A method forming an easily separable portion in packaging film by interposing at least two packaging films between a horn emitting ultrasonic waves and an anvil oppositely disposed to the horn, and vibrating the packaging films by the ultrasonic waves, in which a vibratable layer is provided on the packaging film in at least one of the horn side and the anvil side.

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.

A method and installation for joining a cover layer to an object in a continuous process. Joining is effected with the aid of a joining material having thermoplastic properties, wherein the joining material is arranged between the cover layer and the object and is liquefied using ultrasonic vibration energy. Before application of the ultrasonic vibration energy, the joining material is preheated in a contactless manner with the aid of electromagnetic induction in the region of the glass transition temperature of the joining material or above this glass transition temperature. The object is in particular a chip board and the cover layer an edge strip to be joined to an edge of the chip board.

A technique for stable, high-speed treatment of reinforcement fiber. In a state where a unidirectional fiber bundle is held between a supporting surface of a support and a pressing surface of a resonator ultrasonically vibrating in a pressing direction perpendicular to the supporting surface, a pressed part of the unidirectional fiber bundle pressed by the pressing surface is moved in a longitudinal direction of the unidirectional fiber bundle. By doing so, the unidirectional fiber bundle can be stably treated at high speed when the unidirectional fiber bundle is opened or impregnated with a resin.

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. The sealing mechanism includes a heating zone and a cooling zone. The sealing mechanism also includes a heating element that extends along both the heating zone and the cooling zone, with the heating element having a first profile in the heating zone and a second profile in the cooling zone.

A protective packaging formation device is disclosed herein. The protective packaging formation device can include an inflation assembly having a fluid conduit that directs fluid between first and second overlapping plies of a web material and a sealing mechanism. The sealing mechanism can include a heating zone of the sealing mechanism 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 sealing mechanism can also include a pinch zone that overlaps longitudinally with the heating zone. The pinch zone defined by an isolation element that applies a first pressure to the web material along a first region. The pinch zone is also defined by a support structure and a compression element that applies a second pressure to the web material there-between along a second region transverse to the first region.

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.
