Abstract
Apparatus for counting sheets in stack (17) thereof and inserting tabs (27) between the sheets at predetermined counts, as well as a tabbing method, uses a rotatable counting disc (10) engageable with an edge region of the stack and including a sheet transfer slot (12) to transfer the next sheet to be counted from one face of the disc to the opposed face, upon rotation of the disc. There are means (30) to count the number of sheets transferred and also to advance the disc relative to the stack, as the counting progresses. A tabber (31) is arranged to insert a tab (27) between two sheets of the stack (17) when a predetermined sheet count has been achieved, which tabber (31) projects a tab in a generally radially outward direction with respect to the disc (10), immediately adjacent one face (13) of the disc and in a timed relationship to the rotation thereof. The disc includes a tabbing recess (20) in its one face (13) and into which a projected tab is received for insertion between the last and next sheets to be counted, at the moment of projection of the tab.
