Method of manufacturing tampons
View Patent ↗A method of manufacturing a tampon includes transporting a web of material in a machine direction. The web of material has a base web and an absorbent web. The absorbent web has a free end and a bonded end wherein the bonded end is bonded to the base web. At least the free end of the absorbent web of the web to is controlled to inhibit movement of the absorbent web relative to the base web. The web of material is cut into discrete web segments while controlling at least the free end of the absorbent web. The discrete web segments is bonded to a substrate.
1. A method of manufacturing a tampon comprising:
transporting a web of material in a machine direction, the web of material comprising a base web for defining a cover material of the tampon and an absorbent web, the base web having opposing longitudinally extending side edges, the absorbent web having a free end and a bonded end wherein the bonded end is bonded to the base web, the free end and bonded end of the absorbent web being disposed inward from the side edges of the base web such that the entire absorbent web overlies and is carried by the base web, the free end including a plurality of slits extending in a cross-machine direction;
controlling at least the free end of the absorbent web of the web to inhibit movement of the absorbent web relative to the base web;
cutting the web of material in the cross machine direction to form discrete web segments while controlling at least the free end of the absorbent web; and
bonding the discrete web segments to a substrate.
2. The method set forth in claim 1 wherein controlling at least the free end of the absorbent web of the web comprises controlling at least the free end of the absorbent web using a hold down device.
3. The method as set forth in claim 2 wherein controlling at least the free end of the absorbent web using the hold down device comprises controlling at least the free end of the absorbent web using at least one of an air-knife, vacuum covers, vacuum conveyor, ski, folding board, nip roll, fold finger, surface coatings, and side vacuum assist.
4. The method as set forth in claim 1 wherein bonding the discrete web segments to the substrate comprises bonding the discrete web segments to a continuous web of fleece material.
5. The method as set forth in claim 4 further comprising transporting the continuous web of fleece material in the machine direction and aligning the continuous web of fleece material with the base web.
6. The method as set forth in claim 5 further comprising bonding the base web of the discrete web segments to the continuous web of fleece material.
7. The method as set forth in claim 1 further comprising inspecting the substrate having the discrete web segments bonded thereto.
8. The method as set forth in claim 1 further comprising registering a string with the substrate, the string being spaced from the discrete web segments.
