Abstract
Apparatus for binding a plurality of sheets of paper or other media, including an assembly for clamping a plurality of sheets together with binding edges of respective sheets in alignment, and an assembly for coating the binding edges of the sheets with a quick-drying adhesive. The coating assembly advantageously includes an applicator member such as a porous pad, a supply of adhesive to the applicator member and a slidable mounting for the applicator member to guide the member along the binding edges of the clamped sheets. The applicator pad and adhesive may be contained in a telescoping housing which opens to expose the applicator pad during the process of sliding the housing toward and along the binding edges of the sheets. Although such binding apparatus may be used alone for 'padding' the sheets, it is preferably used in conjunction with a cover folder which includes a stiff spine having a band of pressure sensitive adhesive within an inner channel to which is secured the adhesive-coated edge of the sheets. Advantageously such folder also includes front and back covers. The inner adhesive coating in the channel may be covered with a protective tape to be removed either before or after insertion of the adhesive-coated sheets.
