Abstract
Pinless feeding apparatus for signatures wherein signatures from a printed web are automatically severed and fed to gripping cylinders having gripping fingers on the surface thereof. Positive engagement of each signature with a set of gripping fingers on the gripping cylinder is effected by modifying the rate of transport of each signature as it is severed and by controlling the transporting means so that each signature at any one time is primarily subjected to only one rate of transport.
