Abstract
An apparatus for folding envelope blanks comprises a plurality of platform assemblies which are rotatably mounted on a base. The platform assemblies are incrementally advanced around the base, and separate mechanisms located around the periphery of the base perform the individual folding operations. Particular advantages are achieved by including the side flap folding mechanism on the platform assemblies so that the folded flaps are held firmly in place until the envelope is removed from the machine.
