Abstract
This disclosure relates to a method and apparatus for reliably inserting a tab or other marker into a bobbin of material which is undergoing a converting or other processing step. A spindle having a retention device such as a vacuum or magnetic zone which holds the tab or marker with an adhesive side facing outwardly is described. In operation, the spindle is moved into engagement with the surface of the web and the tab or marker is applied precisely and with considerable force. Reduction in unplaced tabs, paper jams, and tearing may be accomplished by the reduction of user error.
