    摘要: An inflatable-cushion inflation device, comprising:
    an inflation assembly (14) having a fluid conduit (143) configured for inflating with fluid a cushion cavity (114) disposed between first and second layers (105, 107) of a film (100); and
    a cutter assembly (186) that includes:
    a cutting member (192) having an operative position (206) adjacent the inflation assembly to cut the film passing over the inflation assembly;
    a door (218) that is open to expose the cutting member in the operative position and closed to cover a sharp portion (188) of the cutting element in an inoperative position (208).

    摘要: A dunnage crumpling apparatus is provided having first and second entry-side crumpling members and first and second exit-side crumpling members. The first and second entry-side crumpling members define an entry therebetween. The first and second exit-side crumpling members define an exit therebetween that is disposed along the longitudinal path downstream of the entry. A crumpling zone being defined between the entry and exit. The first entry-side crumpling member is configured for moving at an first rate and is associated with the second entry-side crumpling member for moving sheet material through the entry in a first direction along a longitudinal path at an entry rate. The first exit-side crumpling member is configured for moving at an second rate and is associated with the second exit-side crumpling member for moving the sheet material through the exit in the first direction along the path at a exit rate that is slower than the entry rate to crumple the sheet material for producing dunnage. The entry and exit-side crumpling members are displaced laterally along the path with respect to each other to cause shearing of the sheet within the crumpling zone.
