Furthermore, re-use of such because of their resiliency and then snap into spools is very undesirable from the point of view engagement at a point above the centre of the of the ink ribbon manufacturer because such reprojection and thereby lock it frictionally against use may result in the winding thereon and use accidental or unintended separation from the therewith of other ribbons inferior in quality toV socket.
