Abstract: An environmentally friendly single sheet calendar is provided, which includes a single sheet of printed material having first and second opposed edges and first and second opposed faces. A non-metallic, biodegradable binder is disposed along the first edge, with the binder including a rigid bar and a securing element for coupling the rigid bar to the first face of the single sheet. The securing element may, for example, include a layer of adhesive for adhesively coupling the rigid bar to the first face. The adhesive may, for example, be heat activatable.

Abstract: An apparatus is provided for binding a single printed sheet with top and bottom binders to form a single sheet calendar. The apparatus includes a binder feeding mechanism for positioning the top and bottom binders relative to the single printed sheet. The apparatus includes first and second spaced, parallel binding units for respectively securing the top and bottom binders to the single sheet, with the first binding unit having an upper member and a lower member to define a sheet-receiving channel there between. At least one of the upper member or the lower member is heated, and at least one of the upper member or the lower member is controllably movable relative to the other of the upper member or the lower member, to secure one of the binders to the single sheet.

Abstract: A calendar binder having a rigid bar with a front surface and a rear surface, a recess centrally positioned on the rear surface of the rigid bar, a tab having a top end and a bottom end, and an adhesive layer on the rear surface of the rigid bar is adapted to secure the rigid bar to a calendar where at least a portion of the tab is positioned in the recess of the rigid bar. The respective materials for the rigid bar, the tab and the adhesive are suitable biodegradable materials.
