Abstract
A flexible structure inflation device, comprising an inflation assembly configured for insertion between first and second overlapping film layers of a web of material, the inflation assembly having a fluid conduit configured directing a fluid in between the layers to inflate the web; and a cutting member held magnetically in an operative position adjacent the inflation assembly to cut the film passing over the inflation assembly.
Claims30
A flexible structure inflation device, comprising:
- an inflation nozzle configured for insertion between first and second overlapping film layers of a web of material, the inflation nozzle and having a fluid conduit extending therethrough configured for directing a fluid in between the layers to inflate the web, and defining a lateral opening;
- and
- a cutting member held in an operative position, in which the cutting member is partially received in the lateral opening of the inflation nozzle to cut the film passing over the inflation nozzle;
- and
- a guide associating the cutting member with the inflation nozzle to guide the cutting member between the operative position and an inoperative position, in which the cutting member remains associated with the guide, with the guide directing the cutting member into and from the lateral opening, wherein when the cutting member is in the inoperative position, it is spaced from the inflation nozzle.
A flexible structure inflation device, comprising:
- an inflation assembly having a fluid conduit configured for inflating with a fluid a cushion cavity disposed between first and second layers of a film;
- a cutting member having an operative position adjacent the inflation assembly to cut the film passing over the inflation assembly;
- and
- a guide associating the inflation assembly with the cutting member to guide the cutting member between the operative position and an inoperative position, wherein in the operative position, the cutting member is partially received in the inflation assembly;
- and in the inoperative position, the cutting member is spaced from the inflation assembly.
An inflatable-cushion inflation device, comprising:
- an inflation assembly having a fluid conduit configured for inflating with fluid a cushion cavity disposed between first and second layers of a film;
- and
- a cutter assembly that includes a cutting member held magnetically in an operative position, the operative position having the cutting member being partially received in an opening on the inflation assembly to cut the film passing over the inflation assembly, the cutter assembly including a door that is open to expose the cutting member in the operative position and closed to cover a sharp portion of the cutting member in an inoperative position;
- and in the inoperative position, the cutting member is spaced from the inflation assembly.
A flexible structure inflation device, comprising:
- an inflation nozzle having a fluid conduit configured for inflating with a fluid a cushion cavity disposed between first and second layers of a film;
- a shuttle configured to hold a cutting member in an operative position, in which a sharp portion of the cutting member is exposed and adjacent the inflation nozzle to cut the film passing over the inflation nozzle;
- a guide associating the inflation nozzle with the cutting member to guide the shuttle between the operative position and an inoperative position, in which the sharp portion of the cutting member is covered;
- a cutter holder that holds the cutting member;
- and
- a door movable with respect to the cutter holder;
- a second guide operable to partially manipulate the door to open, to expose the sharp portion of the cutting member when the cutting member is moved to the operative position, and to close to cover the sharp portion of the cutting member in the inoperative position;
- and in the inoperative position, the cutting member is spaced from the inflation nozzle.
