Definitions

  • ABSTRACT A delivery mechanism for a single or double folder in which underneath each individual folder a pair of fan shafts are mounted to which fan paddles may be removably secured so that, if both folders of a double folder [30] Foreign Application Priority Data are in operation, one fan shaft of each pair is left with- APL 3 19 9 Germany I p 9 17 235 out paddles and only the paddles on the other fan shafts receive the folded products from the associated folders 52 us. c1. 270/6, 270/10 and deposit them on separate conveyer belts, while [51] Int.
  • the present invention relates to a folder delivery mechanism for a web-fed rotary printing press.
  • an intermediate transfer conveyer which is located between and adapted to connect the two separate delivery conveyers of the two cylinder groups of a double folder and to be controlled so as to run in one or the other direction toward the particular delivery conveyer underneath the folding cylinder group which has been stopped.
  • FIG. 1 shows a double gear folder of theconventional 3:2 ratio in double production per cycle group
  • FIG. 2 shows a double gear folder in double production or collect run with one cylinder group
  • FIG. 3 shows a double jaw folder of a conventional design in double production
  • FIG. 4 shows the double jaw folder according to FIG. 3, but in double production or collect run with one folder and with an additional delivery fan;
  • FIG. 5 shows the double jaw folder according to FIG. 4 in double production or collect run with one folder and with the shaft of the normal fan and the additional fan each carrying only one paddle;
  • FIG. 6 shows a gear folder which may also be employed for a double-collect run
  • FIG. 7 shows a single 2:1 gear folder in double production
  • FIG. 8 shows a single 2:] gear folder in collect run
  • FIG. 9 shows a single jaw folder with two jaw cylinders for a straight run; while FIG. 10 shows the single jaw foldler according to FIG. 9 with two jaw cylinders for a collect run.
  • FIG. 1 illustrates two gear folders running straight in quadruple productionQ
  • the paper webs 101 and 102 are cut to copy length by the cutting cylinders 103 and 104, and then transferred to the folding blade cylinders I05 and 106 and folded in the two pairs of folding rollers 107 and 108. Thereafter, by means of the fans 109 and 110, the folded products are delivered to the conveyer belts 111 and 112 which transport them in the usual manner to the conveyor chains.
  • the paper webs 102 are transferred, for example, to the left folder, while the right folder is stopped.
  • the apparatus is provided in addition to the fans 109 and with further fans 113 and 114 which are adapted to deliver the. copies upon a transfer belt 115 which may be driven so as to convey the copies either to the right or to the left.
  • the transfer belt 115 is driven so as to convey the copies either to the right or to the left.
  • the right folder is stopped as shown in FIG.
  • the transfer belt 1 15 is driven so as to convey the copies toward the right toward the moving delivery belt underneath the stopped folder.
  • the fans of the apparatus are for this purpose designed so that their paddles are re movably secured to their shafts.
  • two of the paddles are removed from the fan 109 and connected to the formerly bare shaft of fan 113 in a position so as to be peripherally offset at an angle of 90 to the paddles of fan 109.
  • the stream of products which is produced in a straight run by the left folder is now divided by the fans 109 and 113 so that one half of the stream will be conveyed toward the left by the conveyor belt 111 and the other half toward the right by the transfer belt 115 from which this right stream will then be taken over and further conveyed toward the right by the right conveyer belt 112.
  • fans 109 and 113 For a collect run, the speed of fans 109 and 113 is reduced to one half of their normal speed and the successive folded products will be delivered alternately to ward the right and toward the left. It is, however, also possible to run both fans 109 and 113 at the normal speed if the number of paddles on each fan is further reduced.
  • the direction of travel of the transfer belt 115 is likewise reversed so that the latter will convey toward the left, and, for example, two of the paddles of fan 1 are removed from its shaft and connected to the shaft of fan 114.
  • the stream of folded products coming from the right folder will then be divided into two separate streams in the same manner as previously described with reference to the operation of the left folder.
  • FIG. 3 illustrates the operation of two jaw folders while folding the paper webs coming from the rotary press.
  • the paper webs 201 and 202 are cut into sheets by the cutting cylinders 205 and 206 which cooperate with the grooved folding cylinders 203 and 204.
  • the sheets are then taken up by these folding cylinders and transferred to the folding jaw cylinders 207 and 208.
  • the folded products are then fed by these cylinders to the fans 209 and 210 and are successively deposited by the latter upon the conveyer belts 211 and 212.
  • this apparatus is improved by the provision of an additional shaft for a fan 213 in a position underneath the fan 209.
  • both fans 209 and 213 are driven at one half of the normal speed of fan 209 so that the folded products will be alternately deposited upon the two delivery belts 211 and 212. It is, however, also possible to drive both fans 209 and 213 at the normal speed if they are provided with a still smaller number of paddles. Thus, for example, as illustrated in FIG. 5, each fan 209 and 213 is only provided with a single paddle which is mounted on its shaft in such a position that when the paddle of fan 213 just receives one folded product, the paddle of the other fan 209 is peripherally offset at an angle of about 180 to its receiving position.
  • FIG. 6 illustrates a gear folder which is designed so as to permit a straight, collect or double-collect production as disclosed in my copending application, Ser. No. 765,189, filed on Oct. 4, 1968 now US. Pat. No. 3,521,878, patented July 28, 1970.
  • This folder may be changed over from a straight run to a collect run by stopping one gear folding cylinder group, for example, the cylinders 307 and 308 together with the associated fan, while the right conveyer belt 306 continues to run.
  • the present invention as already described with reference to FIGS.
  • 1 to 5 may also be applied to this apparatus by providing an additional fan 301 and a transfer belt 302 so that the stream of products will be equally divided by the two fans 301 and 304 which will alternately deposit one folded product of the stream upon the conveyer belt 305 running in one direction and the next product upon the transfer belt 302 which runs in the opposite direction and then passes these products to the conveyor belt 306.
  • both conveyer belts 111 and 115 may also be driven in the same'direction so as to deliver the folded products toward the same side
  • the two conveyer belts 211 and 212 may also be movable in opposite directions to each other so as to deliver the products to different sides.
  • FIG. 7 illustrates a single 2:1 gear folder with a conventional split delivery by means of two fans 401 and 402.
  • FIG. 9 illustrates a single jaw folder with two jaw cylinders 501 and 502 in a straight-run production, whereas in a collect-run production as shown in FIG. 10, only one of the two jaw cylinders, for example, the cylinder 501, will be operative and transmit the folded products to the delivery means.
  • the invention therefore again provides a second fan 503 in addition to and laterally adjacent to the fan 505, and a transfer conveyer belt 504 for receiving the products from this second fan 503 and passing them to the other delivery belt.
  • One half of the number of paddles of fan 505 is then again removed from its shaft and connected to the formerly bare shaft of fan 503 so that the two fans 503 and 505 will then alternately deposit the folded products upon the two belts underneath.
  • a folder delivery mechanism wherein there is only one press feeding to said two folders, one of said folders having its two spaced apart delivery fans delivering the printed product from said one folder alternately to said conveyor under one of said fans while the other cooperating delivery fan delivers to said conveyor therebelow serving as said transfer conveyor, and
  • said last conveyor also receiving the products conveyed by said transfer conveyor.
