    摘要： A speed-responsive jaw spacing adjustment system for a jaw cylinder ( F 3 ) at the folding station ( F ) of a web-fed printing press where a printed paper web ( W ) or a plurality of such webs in superposition are cut into successive sections ( PC ), and each web section folded into a signature. The jaw cylinder has pairs of fixed and movable jaws ( J 13 and J 12 ) for engaging and folding each web section as its midpart is inserted therebetween.
    For automatically adjusting the spacing between the fixed and movable jaws to the running speed of the printing press, the adjustment system comprises a press speed circuit (50) for providing a press speed signal indicative of the current running speed of the press, a jaw spacing circuit (70) for providing a jaw spacing signal indicative of the current actual spacing between the fixed and movable jaws, and a jaw spacing adjustment circuit (90) responsive to the press speed signal and jaw spacing signal to cause an electric motor (31) to drive a jaw spacing adjustment mechanism (20) for adjustment of the jaw spacing to the current press speed.

    摘要： A blanket cylinder for use in offset lithography in combination with a blanket assembly (T) including a blanket (28) and a carrier sheet (C) therefor. The carrier sheet of the blanket assembly has a major portion (20) to which the blanket is attached, a first flange (21) at an acute angle to the major portion, a second flange (27) at an obtuse angle to the major portion and a rim (23) at an acute angle to the second flange. The blanket cylinder comprises a cylinder assembly (B) having formed therein an undercut groove (7) with an entrance slot (6) bounded by and between a first (24) and a second (25) longitudinal edge, the first longitudinal edge being cross-sectionally shaped to be engaged by the first flange (21) of the carrier sheet (C), and a retainer spindle (12) mounted in the undercut groove in the cylinder assembly for bidirectional rotation therein.
    In order to hold the blanket assembly (T) closely wrapped around the cylinder assembly (B), the retainer spindle (12) is cross-sectionally shaped to include a pull-in hook (16) for engaging the rim (23) of the carrier sheet (C) in order to pull the second flange (27) thereof into the undercut groove (7) with the rotation of the retainer spindle in a first direction, and a push-out ledge (28) for abutment against the rim (23) of the carrier sheet in order to push the second flange (27) out the undercut groove with the rotation of the retainer spindle in a second direction. The retainer spindle (12) is biased by a pair of torsion springs (17, 18) to turn in the first direction.
