PCT No. PCT/SE87/00196 Sec. 371 Date Dec. 16, 1988 Sec. 102(e) Date Dec. 16, 1988 PCT Filed Apr. 14, 1987 PCT Pub. No. WO87/06217 PCT Pub. Date Oct. 22, 1987.Method of gathering signatures wherein signatures lying face to face in a stack and standing on the back edge, are fed to a delivery position with the face engaging an abutment (15). The signature (S1) in the delivery position is pushed up so that it projects from the stack at the opposite edge. Then, it is gripped at said edge so as to be carried by a continuous movement in an unchanged moving direction successively through the steps of being extracted from the stack, turned up-side-down and opened while being deposited upon a conveyor path (11). The invention also relates to a machine for gathering signatures comprising means (16) for feeding the signatures in the manner described above to the delivery position. A device (32) having carriers (33, 34) to be engaged with the face of the signature (S1) in the delivery position, can be reciprocated along the plane of the signature in the delivery position to lift said signature to a position wherein the opposite edge projects from the stack tangentially to one (22) of two drums (22, 23) forming part of the extraction means, said drums having grippers (26, 27, 28, 29) and being continuously rotated about parallel axes in opposite rotational directions.
