Abstract

A method is disclosed for the fabrication of tampon applicator tubes in which the forward ends of thin-walled tube blanks are crimped to provide a plurality of longitudinal fold lines, folded and compressed to form a plurality of pleats, exercised to weaken the fold lines to facilitate ejection of the tampon and refolded under compression to form a pleated, generally conically shaped forward tube end having a relatively smooth exterior surface.

Claims (4)

1. A method for shaping the end portion of a tube comprising: crimping said end portiOn to provide a plurality of longitudinally disposed folds; folding and compressing said crimped end portion into a plurality of pleats, thereby forming said tube end into a generally conical shape; penetrating said folded forward end of said tube with male die means to at least partially unfold said forward end; and, refolding and compressing said forward end portion into said pleated, generally conical shape.
2. A method, as defined in claim 1, in which: said forward end portion is unfolded progressively in successive stages.
3. A method, as defined in claim 1, in which: said tube end is substantially fully unfolded in a single operation by positioning said male die means within said tube and moving said die means forwardly to penetrate said forward end.
4. A method, as defined in claim 1, which includes: forming a small, centrally oriented aperture in said forward end portion of said tube during the refolding step.
