A discrete attachment tab 80 is extending from the sleeve end 38 and is attached to the person's hand. The attachment tab extends from the attached portion 88 to the extended end 89.

(29) Referring now to FIGS. 12 to 16, an exemplary method of making an inverting digit bandage requires a multi-step method or process. As shown in FIG. 12, a form 230 is used to form the inverting digit bandage. A dressing 60 is applied to and covers the form, and then a bandage adhesive 50 is applied. However, a dressing may be configured on the form already having an adhesive. As shown in FIG. 13, an absorbent material 40 or portion is attached to the dressing by the adhesive. Note that the dressing layer extends down further than the absorbent material, as it will form the attachment tab. As shown in FIG. 14, the assembly shown in FIG. 13 is then inverted onto a second form 230. The dressing 60 is now on the outside surface and the absorbent material 40 is on the inside surface, or faces the second form 230. Note that the deployment strip 90 and deployment loop 94 are placed on the second form 230 before the assembly was inverted onto the second form. This step configures the deployment strip in the correct location for later use. As shown in FIG. 15, a portion of the extended end of the bandage, or the attachment tab 89, is inverted and adhesive 50 is applied. Note that adhesive may be applied to the dressing in FIG. 12 or 13, that extends to the attachment tab. However, the exposed adhesive has to be covered prior to inverting the bandage onto the second form 230. As shown in FIG. 16, the deployment strip 90 and release layer 86 are attached to the attachment tab 80. The deployment strip may be coupled to the release layer prior to placement on the second form. Alternatively, the deployment strip and release layer may be attached prior to placement on the second form. With the release layer attached to the exposed adhesive 50, as shown in FIG. 16, the inverting digit bandage is ready to be rolled up, or inverted. The inverted digit bandage 10 shown in FIG. 17 produces an inverting digit bandage, as shown in FIG. 2, when inverted to expose the deployment loops and form a toroid portion 34.
