摘要：A signature transfer device in a folder for a rotary printing press includes aplurality of adjustable-pressure rollers for holding down upper tapes for transferring asignature with a strong force to prevent the upper tapes from slipping on the signatureand hence, to prevent the latter from being inclined while the signature is being

transferred toward a position in which the signature will be folded on itself by a chopperblade. The signature transfer device includes an adjustment mechanism for adjustinggaps between the upper tapes and the lower tapes to reduce the force with which thesignature is sandwiched between the upper and lower tapes, so that the signature isprevented from being forcibly pressed against front lays in the folding position. With thisarrangement, the signature is prevented from getting wrinkled upon abutment againstthe front lays, and from becoming inclined relative to the chopper blade when thesignature approaches and arrives at the folding position. Therefore, desired

perpendicularity of the signature relative to the chopper blade can be maintained duringoperation of the signature transfer device.
