The tool-support apparatus has a tool-support, which can be secured on a machine frame or housing of the grinding machine, for the support during the grinding process of a tool that is to be ground, and an arresting apparatus for securing the tool support on the machine frame or housing. The system also includes various color schemes associated with the first and second line-ups in order to facilitate consumers’ identification and selection of the appropriate absorbent article configuration for a particular wearer.
