A welding station for an installation for manufacturing packages with pads, the welding station including a plurality of longitudinal welding heads. Each welding head is configured to weld to one another two superposed sheets as said sheets advance in a first direction and may include a welder to apply heat on an action area. Each welding head has a main body, a first traction belt wound in the main body and a second traction belt wound to said main body, parallel to the first traction belt and separated from the first traction belt by a separation gap in a second direction which is transverse to the first direction. The action area is arranged in said separation gap, between both traction belts. Each of the longitudinal welding heads is configured to be able to be moved along the second direction.

A packing material including a plurality of discrete cushioning elements and methods for making the same. The discrete cushioning elements may be cellulosic cushioning elements. A flexible linkage may connect the plurality of discrete cushioning elements in the packing material. The packing material may also include a bottom cellulosic sheet connected to a top cellulosic sheet with the plurality of cellulosic cushioning elements positioned between the top cellulosic sheet and the bottom cellulosic sheet. The packing material may also be a molded packing material that includes bonds comprising adhesive and cellulosic fibers. The adhesive and cellulosic fibers of the bonds may be dispersed between the folds of each of the cellulosic cushioning elements.

The present disclosure is directed to a web inflation and sealing apparatus. The device may include a support member for holding a supply of web material and sealing apparatus may include an inflation and a sealing assembly operable to inflate the web material with a fluid by directing the fluid between superimposed plies of the web material and to seal the plies together to seal the fluid therein. The apparatus may include a guide member positioned between the support member and the inflation and sealing assembly such that when the web material is routed from the supply toward the inflation and sealing assembly via the guide member the web material follows a curved longitudinal path. The guide member may define a web-supporting surface extending transversely to the longitudinal path with an elevated profile portion defining at least a portion of the web-supporting surface.

A machine includes an inflation arrangement, a sealing arrangement, and a tensioning device. The inflation arrangement provides air at a first pressure to inflate a first web of a first type of inflatable material, provides air at a second pressure to inflate a second web of a second type of inflatable material, receives the first and second webs, and aligns the first and second webs on the machine. The first pressure is different from the second pressure. The sealing arrangement seals the first and second types of inflatable material. The tensioning device provides a first tensioning force to the first web as the first web moves between the inflation and sealing arrangements and provides a second tensioning force to the second web as the second web moves between the inflation and sealing arrangements. The first tensioning force is different from the second tensioning force.

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.

An inflatable packaging for storing multiple glass bottles made from a sheet that has a longitudinal axis and a traverse axis. The sheet is folded along six or more traverse fold lines spaced from each other to form a row of two or more pouches. The inflatable packaging can have two or more of such rows separated by a line of weakness. Each pouch has a front wall, a rear wall, a base, and an open-top for storing the glass bottle. Two adjacent pouches are separated by a dividing panel, wherein the dividing panel is corrugated in a biconcave shape.

An inflatable web includes an inflation zone, a first inflatable panel in fluid communication with the inflation zone, and a second inflatable panel in fluid communication with the inflation zone. The first inflatable panel includes a first sheet juxtaposed on a second sheet. The first and second sheets are sealed together to form inflatable chambers. The second inflatable panel include a third sheet juxtaposed on a fourth sheet. The third and fourth sheets are sealed together to form inflatable chambers. The inflatable film is configured to be inflated by an inflation and sealing machine configured to direct gas into the inflatable chambers of the first and second inflatable panels via the inflation zone and to individually seal the inflatable chambers of the first and second inflatable panels.

A packing material including a plurality of discrete cushioning elements and methods for making the same. The discrete cushioning elements may be cellulosic cushioning elements. A flexible linkage may connect the plurality of discrete cushioning elements in the packing material. The packing material may also include a bottom cellulosic sheet connected to a top cellulosic sheet with the plurality of cellulosic cushioning elements positioned between the top cellulosic sheet and the bottom cellulosic sheet. The packing material may also be a molded packing material that includes bonds comprising adhesive and cellulosic fibers. The adhesive and cellulosic fibers of the bonds may be dispersed between the folds of each of the cellulosic cushioning elements.
