Compliant embosser assembly

An embossing assembly for forming an embossment pattern on a tube blank, the embossing assembly comprising:

• a) a first roll comprising:
• i) a first shaft having a first axis of rotation;
• and
• ii) an embossing element joined to the first shaft, wherein the embossing element extends outward from and surrounds the first shaft, the first shaft and embossing element being configured such that a tampon applicator tube blank can at least partially surround the first shaft and the embossing element;
• and
• b) a second roll having a second axis of rotation, wherein the first axis and the second axis are generally parallel, wherein the second roll is configured to engage the tampon applicator tube blank, wherein the second roll comprises a second shaft and a hub joined to the second shaft, wherein the hub comprises:
• i) an engagement region disposed outward from the second shaft, wherein the engagement region is configured to apply pressure to the tampon applicator tube blank adjacent to the embossing element thereby causing part of the tampon applicator tube blank to at least partially conform to the shape of the embossing element, and wherein the engagement region has an arc length greater than a diameter of the embossing element;
• ii) a non-engagement region disposed outward from the second shaft, wherein the non-engagement region transitions into the engagement region at two places about a circumference of the outer support, and wherein the engagement region and the non-engagement region together surround the second roll and,
• iii) an inner support joined to the second shaft such that the inner support at least partially surrounds the second shaft, an outer support joined to the inner support such that the outer support at least partially surrounds the inner support, and a compliant material having a durometer of about 75 Shore D disposed between the outer support and the inner support, wherein the outer support comprises at least a portion of the engagement region, and wherein the compliant material is more compliant than the outer support.

• i) an inner support joined to the second shaft;
• ii.) a compliant material joined to and disposed outward from the inner support, wherein the compliant material has a durometer of about 95 Shore A;
• iii) an outer support joined to and disposed outward from the compliant material, wherein the outer support comprises a pair of shoulders and an engaging surface, wherein the embossing element is received between the shoulders;
• iv) an inner lateral stabilizer extending from the compliant material through the inner support, wherein the compliant material is more compliant than the outer support;
• v) an engagement region disposed outward from the second shaft, wherein the engagement region is configured to apply pressure to the tampon applicator tube blank adjacent to the embossing element thereby causing part of the tampon applicator tube blank to at least partially conform to the shape of the embossing element, and wherein the engagement region has an arc length greater than a diameter of the embossing element;
• and
• vi) a non-engagement region disposed outward from the second shaft, wherein the non-engagement region transitions into the engagement region at two places about a circumference of the outer support, and wherein the engagement region and the non-engagement region surround the second roll.
