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.

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 apparatus and method for making a three-dimensional object from a solidifiable material using a linear solidification device is shown and described. The apparatus includes a solidification substrate assembly that is tiltable about a tilting axis to peel a solidification substrate from a recently formed object surface and to level the solidification substrate assembly and squeeze out accumulated solidifiable material between the solidification substrate and the recently formed object surface. Intelligent peeling and leveling may also be provided by providing a tilting parameter database that is used to adjust tilting parameters based on object geometry and/or solidifiable material properties.
