摘要： 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.

摘要： This invention includes a mechanism for unfolding signatures so that inserts can be put in the central fold. The signature, of which an example is a tabloid, comprises a plurality of folded, substantially identically-sized flat sheets of paper, each folded sheet being inserted within the fold of its next contiguous sheet so that a common center fold for the signature is formed with the successsive sheets formed as embracing layers. Each successive outer layer is underlapped at its free edges relative to the free edges of the layer next innermost to it, by which means a tapered free edge is formed. The means comprises a supporting table, a sucker wheel with an axis of rotation, and a perforated peripheral surface with a peripheral tangential speed equal to the forward speed of the signature so as periodically to engage the uppermost portion of a folded structure. A transfer means moves the folded structure along the supporting table in a path parallel to the center fold at said forward speed. A source of subatmospheric pneumatic (suction) pressure is periodically connected to the perforated peripheral surface by timer means. A shelf overlays at least a part of the supporting table and receives the free edge which is lifted by the sucker wheel. According to a preferred feature of the invention, the sucker wheel is driven by a motor, and the timer means connects the peripheral surface to subatmospheric pressure with a frequency less than the frequency of revolution of the sucker wheel.
