A form-fill-and-seal (FFS) packaging machine is described wherein a zipper is attached to the package simultaneously with the sealing operation at the sealing and evacuation station. The attached zipper is thereafter welded in place at the zipper welding and cutting station. A zipper blank feeder and a channel-forming die with an impulse sealer are integrated into the sealing die of a packaging machine forming a combination work station. The zipper is installed at an existing work station and shares the existing lifting device. This enables the retrofitting of an FFS packaging machine to include a zipper attachment function without changing the footprint thereof. The combination work station forms a channel for the zipper blank between the thermoformed web and the lidstock. While the sealing die is providing a seal about the lid, the impulse sealer in the channel-forming die attaches the zipper to an initial attachment portion of the packaging film. Upon completion of the package, this initial attachment portion, if retained, becomes the tamper-indication portion of the package. Both the sealing and evacuation station and the zipper welding stations of this invention are of jacketed construction enabling the temperature control of the zipper blank throughout the installation procedures.

The cleaning device of claim 1, wherein the head includes at least ten of the transverse slots. 3. The cleaning device of claim 1, wherein each ridge further includes opposing side walls, and further wherein at least one of the opposing edges for each of the plurality of slots is a corner defined by an intersection between the outer surface and respective side wall. 4. The cleaning device of claim 1, wherein the outer surfaces combine to define a uniform radius of curvature. 5. The cleaning device of claim 4, wherein the radius of curvature is at least 5 mm. 6. The cleaning device of claim 5, wherein the radius of curvature is not greater than 20 mm. 7. The cleaning device of claim 1, further comprising: a data storage tape cartridge including an enclosure and a storage tape wrapped about a tape reel assembly; wherein the cleaning head is disposed within the enclosure and positioned to selectively engage the storage tape. 8. The cleaning device of claim 1, further comprising: a tape drive including an enclosure configured to receive a data storage tape cartridge; wherein the head is disposed within the enclosure. 9. The cleaning device of claim 1, further comprising: a feeding mechanism associated with the head and configured to drive a magnetic tape across the tape-receiving face as part of a magnetic tape manufacturing process. 10. A method of removing debris from a tape media, the method comprising: providing a cleaning head having a front and a plurality of transverse slots formed in the front to define a plurality of spaced ridges each having an outer surface extending between opposing transverse edges, the outer surfaces combining to define a curved, tape-receiving face; driving the tape across the face in a generally perpendicular fashion relative to the transverse edges such that a transverse chordal segment of the tape contacts a leading transverse edge of at least three of the ridges as the tape is driven across the face; and removing debris from the tape via the driven contact between the tape and the leading transverse edges. 11. The method of claim 10, wherein the cleaning head includes at least ten of the ridges, and further wherein the step of driving the tape includes causing the transverse chordal segment to contact a leading transverse edge of at least ten of the ridges. 12. The method of claim 10, wherein the outer surfaces combine to define a radius of curvature in the range of 5-20 mm. 13. A tape media cleaning device comprising: a head having a front defined by opposing outer regions and a central region; a plurality of transverse cavities formed in the front to define a plurality of lands in the central region each having a flat outer face extending between opposing sides with opposing corners being formed at an intersection between the outer face and the opposing sides, respectively; and first and second outriggers formed at the opposing outer regions, respectively, wherein each of the outriggers are spaced from a corresponding, adjacent land; wherein the plurality of cavities are configured to establish a sub-ambient condition as a tape is driven across the outer faces in a generally perpendicular fashion relative to the lands such that the tape at least partially wraps about a leading corner of at least three of the lands to effectuate removal of debris. 14. The cleaning device of claim 13, wherein the head includes at least four of the lands. 15. The cleaning device of claim 13, wherein the plurality of cavities include opposing outer cavities s
