Abstract

A machine for inserting discs into envelopes including a disc conveyor in which discs are removed one by one from a stack and conveyed past a detecting station to a loading station together with an envelope conveyor in which envelopes from the hopper are conveyed to the loading station in advance of arrival of discs and positioned for receiving the disc through the open end of the envelope. The operation of the envelope conveyor is initiated by passage of a disc by the detecting station so that unless a disc is moving no envelope is picked from the envelope stack. After package formation the packages are conveyed to a transfer conveyor past a detector which determines a predetermined stack of conveyors for each station on the transfer conveyor.
