Abstract:
1. A mechanism to aid in startup of winding a web onto a winding core to form a roll of the web and to aid in subsequent splicing of the web during unwinding of the roll, the mechanism comprising: a core component comprising a core-attaching portion structured and arranged to attach to the core and having a free end portion joined to the core-attaching portion, the free end portion extending out from the core when the core-attaching portion is attached to the core, the core component comprising a substrate having an upper surface and a lower surface, a layer of release material being disposed on the upper surface of the substrate, a portion of the substrate being folded over along a fold line such that the free end portion of the core component comprises two layers of the substrate and the core-attaching portion comprises one layer of the substrate, the layer of release material forming both opposite surfaces of the free end portion; and a web component comprising an adhesive splicing tape structured and arranged to attach to a tail end of a web with a leading portion of the splicing tape extending out from the tail end of the web, the leading portion being adhered to the free end portion of the core component with sufficient adhesive bonding strength to remain attached to the free end portion when winding tension is exerted between the core and the tail end of the web during startup of winding of the web onto the core to form a roll, yet the release material on the free end portion allowing the leading portion of the splicing tape to detach from the core component at completion of unwinding of the roll such that the leading portion extending from the tail end of the web is exposed for attachment to a leading end of another web being unwound from a new roll to splice the webs together.
