Abstract
An adhesive lifting mechanism for retrieving retractable material from an underlying surface includes a housing having a retrieval opening. A tape spool, as well as applicator and, retrieval rollers, are mounted within the housing. The rollers have circumferential engagement surfaces that protrude through and outwardly from the retrieval opening. The rollers are engaged by successive segments of tape extending from the supply spool and across the retrieval opening. Each roller is positioned in the housing for being driven rotatably across an underlying surface with the peripheries of the respective rollers simultaneously bearing against the underlying surface such that a first segment of tape lifts extractable matter from the underlying surface and is retrieved into the housing. A fresh, second segment of tape from the supply spool is then pulled across the opening and peripherally engaged with the applicator roller.
