Abstract: A marker insertion apparatus automatically removes a marker from a roll of marker material and applies the marker to an applicator. The markers mount to a backing sheet and are peeled from the sheet by passing over a peel bar. Jaws are positioned near the peel bar and configured for gripping an end marker. An applicator member inserts intermediate the jaws and has the end marker pressed onto the applicator and torn from the roll. In a first embodiment, the applicator is a paddle applicator for inserting markers between opposing pages, and in a second embodiment the applicator is a bayonet: applicator for inserting markers into the spine of a book.

Abstract: A face mask (10) covers the nose and mouth of the wearer and includes a band (24) to retain the mask member (12) in position.

The band (24) extends around the back of the neck and provides for retaining the mask (10) at the front of the wearer when not worn. Ends (26) of the band (24) are elastic to provide a snug fit for the mask (10).
