  • Knife shaft 132 is rotatably mounted and supported by a pair of spaced bearing lugs 136 integral with and projecting from the stationary lower suction chamber 68 (Fig. 1).
  • compression spring 138 surrounding one end-portionof shaft 132 and confined between one of the lugs 136*and a collar 140 on shaft 132 is employed to maintain the desirable spring-urged contact between the ledger plate 130 and knife blade 128.
  • cam shaft 64 To the front end of cam shaft 64 is secured another cam 172 provided with a cam track- 174 which tracks a cam roller 176 pivotally mounted on the free'end of a cam lever 178 (Figs. 1 and 3) which in turn is loosely mounted on a stud 180 held by a yoke-shaped lug 183 secured to the frame 32 of the machine.
  • cam lever 178 From the hub of the cam lever 178 projects an arm 182 'whose free end is suitably connected to one end ofa horizontal rod 184 whose other end is connected toa gate valve plate 186 (Figs. 1, 4 and 6) which by means of a pair of guide rails 188 is slidably mounted to the top of'th'e suction box 76 in suction distributing housing 78.
  • Gate valve 186 is provided with two spaced ports'190 and 192 while suction box 76 consists of three separatechambers 194, 196 and 198.
  • Chamber 194 by means of duct 200 (Fig. 6) is connected to the tube 74 which, as mentioned heretofore, is connected with the hollowstand 70 and the table plate suction charnber 68.
  • Chamber 196 by means of ducts 202 is connected to the tube 112 which is connected to reciprocating upper suction chamber 80, also mentioned heretofore.
  • Chamber 198 by means of a duct 204 connects with two other chambers 206 and 208 in housing 78 which, in turn, by's Adjustble ducts 210 and 212 (Fig; 2), respectively,- 81 connected with the wrapper suction head 214 and surrounding shell 216, respectively, of an intermittently rotating duplex wrapper die turret 218, similar to the one shown and describer in U.S. Letters Patent 2,316,825 granted to me on April 20, 1943.
  • the suction may be supplied from any suitable source (not shown) through a tube 220 connected to a chamber 222 secured and connected to the side of housing 78.
  • cam 172 through cam lever 178, arm 182 and rod 184 shifts the gate valve plate 186 to a position where its port 192 aligns with the chamber 196 of suction control box '76 thus causing a shutting off of the suction to the lower suction chamber 68 and an opening of the suction passage through tube 112 to the upper suction chamber which at this moment is located and dwelling above the lower suction chamber 68-and the leading end portion of the cut wrapper strip S.
  • the change of the suction from the lower suction chamber 68 to the upper suction chamber 80 effects a release of the leading end of strip S from the lower suction chamber 68 and the table plate 66 and an adherence of said leading end to the. perforated bottom side of the upper suction chamber 88.
  • the cut wrapper strip S is also carried forward and finally onto the wrapper suction head 214 of the duplex wrapper die turret 218.
  • the cut wrapper strip S is carried forward by said chamber 80, the feed rollers 12 and 14 feed a new length of web onto the horizontal table plate 66 but, due to a slight difference in ratio of the feed roller driving gear 42 and the rack actuating gear 100, the rack 98 which effects the forward motion of chamber 80, advances the latter and, consequently, the cut wrapper strip S, at a slightly higher linear speed than the leading edge of the web W which at the same time is advanced by the feed rollers 12 and 14 onto the table plate 66, thus creating a gap between the trailing end of the cut wrapper strip S and the leading edge of the web'W on the table plate 66.
  • the cut wrapper strip S lies directly over the wrapper suction head 214 and the leading edge of the web fed forward over the table'plate 66 registers approximately with the extreme forward end of the latter.
  • the cam 172 effects a shifting of the gatevalve plate 186 which causes the suction to shift from the upper suction chamber 80 to the wrapper suction head 214and shell 216 of the duplex wrapper dieturret and also allowing suction to reach the lower suction chamber 68.
  • Brackets 226 are carried by a horizontal rod 228 projecting from and secured to a member 230 (Figs. 2 and 4) carried by and mounted on a suitably shaped carrier bracket 232 slidably supported by a horizontal rail 234 mounted on bed plate 30. To the lower edge of carrier bracket 232 is secured a guide bracket 236 carrying a stud 238 which, by means of a link 24! (Figs.
  • actuating arm 242 which extends from and is integral with the cam lever 56 which, as previously described, represents the actuating means for the feed rollers 12 and 14- as well as the reciprocating upper suc tion chamber 89 which forwards the cut wrapper strip S from the table plate 66 to suction head 214 of the wrapper die turret 218.
  • the cutting operation is accomplished by slightly lowering the suction head within the surrounding die 244 so that when the rollers 224 roll over the sharp upper edges of said die, a desirable shaped wrapper is cut from and out of the wrapper strip S.
  • the suction head is raised and the cut wrapper is picked up by a suitable transfer mechanism (not shown).
  • the suction head is then lowered again with its top surface flush with the upper edges of the die 24dand the turret again turns 180 in the direction of the arrow in Fig. 2 to bring said suction head again into wrapepr strip receiving position.
  • a suction nozzle 246 As the shell 216 passes beneath said nozzle.
  • the latter by means of a suitable tubing 248 is connected to a conventional cyclone separator 250 which in turn by means of tube 252 (Fig. 1) is connected to the chamber 222 of the suction system described heretofore.
  • the suction nozzle 246 and tube 248 is supported by a suitable bracket 254 secured to bracket 92.
