摘要： A mechanism in a web-fed rotary press for cutting a continuous web ( W ) of printed paper into discrete sheets ( W 1 ) and folding the successive sheets into the form of signatures ( W 2 ). Included are a cutting cylinder (1) having a cutting blade (4), a folding cylinder (2) held opposite the cutting cylinder and having pins (7) on its surface for piercing the web of printed paper so as to cause the same to enwrap the folding cylinder, there being a counter cutting bar (5) in the folding cylinder for receiving the cutting blade on the cutting cylinder in order to have the web of paper thereby severed successively into sheets ( W 1 ), a foldng blade (8) mounted to the folding cylinder for travel radially thereof in order to push each sheet off the folding cylinder surface, a jaw cylinder (3) held opposite the folding cylinder and having a cavity (10) extending parallel to its axis and opening to its surface for receiving the folding blade on the folding cylinder together with the sheet being pushed thereby, and a movable jaw (13) arranged in the cavity for movement toward and away from a fixed jaw (11) in order to crease the sheet that has been pushed into the cavity, by catching the sheet between the jaws.
In order to keep the printed surfaces of each sheet ( W 1 ) folded, superimposed and contacted each other from being ink-stained by pressing hard against the jaws (11, 13) upon insertion in the cavity, an indentation (17) is formed in the fixed jaw (11) so as to be in opposed relationship to an insert part (21) of the folding blade on the folding cylinder (2) in the cavity as the folding blade is inserted in the cavity (10). Preferably, a similar indentation 19 is formed also in the movable jaw (13).

摘要： A mechanism in a web-fed rotary press for cutting a continuous web ( W ) of printed paper into discrete sheets ( W 1 ) and folding the successive sheets into the form of signatures ( W 2 ). Included are a cutting cylinder (1) having a cutting blade (4), a folding cylinder (2) held opposite the cutting cylinder and having pins (7) on its surface for piercing the web of printed paper so as to cause the same to enwrap the folding cylinder, there being a counter cutting bar (5) in the folding cylinder for receiving the cutting blade on the cutting cylinder in order to have the web of paper thereby severed successively into sheets ( W 1 ), a foldng blade (8) mounted to the folding cylinder for travel radially thereof in order to push each sheet off the folding cylinder surface, a jaw cylinder (3) held opposite the folding cylinder and having a cavity (10) extending parallel to its axis and opening to its surface for receiving the folding blade on the folding cylinder together with the sheet being pushed thereby, and a movable jaw (13) arranged in the cavity for movement toward and away from a fixed jaw (11) in order to crease the sheet that has been pushed into the cavity, by catching the sheet between the jaws. In order to keep the printed surfaces of each sheet ( W 1 ) folded, superimposed and contacted each other from being ink-stained by pressing hard against the jaws (11, 13) upon insertion in the cavity, an indentation (17) is formed in the fixed jaw (11) so as to be in opposed relationship to an insert part (21) of the folding blade on the folding cylinder (2) in the cavity as the folding blade is inserted in the cavity (10). Preferably, a similar indentation 19 is formed also in the movable jaw (13).
