Abstract: A method and device for feeding signatures on to a fixed horizontal saddle of an input conveyor to a sewing machine; whereby the signatures, arranged with the backs facing rearwards, lying in respective vertical planes parallel to the fixed saddle, and separated by a distance of less than the maximum width of the signatures, are fed along a conveyor sloping downwards in the travelling direction of the input conveyor; the signatures being fed in an oblique direction in relation to the backs; each signature having a top corner projecting laterally from the stream of signatures travelling along the conveyor, which corner is engaged by a number of suction type parting heads located along, and moving reciprocatingly in the travelling direction of the signatures along the conveyor; and the signatures being so fed to an accelerating device designed to successively withdraw the signatures off the conveyor, and transfer the same, now parted, on to the fixed saddle; the parted front corner of each signature being guide

Abstract: A book sewing machine having an incorporated automatic feeder is disclosed. The automatic feeder has two stacks of signatures and acts to remove one signature from each stack simultaneously. The two signatures are both opened and then placed directly astride a sewing saddle of the sewing machine. The sewing saddle carries means for adjusting the spacing of the two signatures, and means for holding the two signatures in place as the sewing saddle moves to the sewing position where the two signatures are both sewn in one operation and then passed for further processing. One embodiment incorporates an automatic paster which applies paste to the signatures adjacent their backbones prior to placing them on the sewing saddle.
