Abstract: A board inserter for use with a conveyor belt system provides for the automatic insertion of paper boards, or like materials, into a continuous stream of shingled paper sheets moving along the conveyor belt system. The boards are inserted into the shingled paper stream without disrupting the flow of the stream.

Abstract: A stack of printed sheets is divided into individual tablets by inserting paper boards at intervals of a predetermined number of sheets in the stack. A continuous filament is threaded in zig-zag fashion across each successive board before a binder is coated on one face of the stack to secure the edges of the sheets and boards together. With one end of the filament anchored, the other end is pulled out from between each board and the adjacent sheet in a direction to sever the coating at the edge of the board. As each loop of the zig-zag filament is withdrawn, it cuts the coating at each successive board, dividing the stack into separate tablets.

Abstract: A board inserter for use with a printing press provides for the automatic insertion of paper boards or the like between predetermined numbers of printed sheets as they emerge from the printing press. The board inserter is used to make note pads or the like in which stacks of paper are attached to a heavier paper board backing.
