  • Registration means 202 is interposed between said die and segmenting wheels to insure that said wheels are immeditely brought into proper registration.
  • Registration means 202 includes pin 216, extending normally from and secured to the side face of sprocket wheel 198, latch dog 218 pivotably mounted by means of pin 220 to the side face of sprocket wheel 192, and spring 224 fixed at one end to said side face of sprocket wheel 192 and adapted to bias latch dog 220 against intermediate shaft 196 to rotate same.
  • shaft 196 carries with it sprocket wheel 192 which is fixed thereto.
  • sprocket wheel 192 rotates, face 228 of latch dog 220 engages against fixed pin 216 and rides therealong once during each rotation to pivot said latch dog about pin 222 against the bias of spring 224, said spring returning said latch dog back into engagement with shaft 196 when pin 216 clearsface 228.
  • Idler motor 204 could be coupled through an override clutch directly to shaft 72.
  • said shaft would be journaled through gear 196 and registration means 200 would be interposed directly between said gear and said shaft, means being provided for mounting latch dog 220 on shaft 72 for pivoting relative thereto.
  • the foregoing drive and connecting arrangement insures that the web marking apparatus is fully responsive to the rotation of the segmenting wheel of the segmenting means to which said web marking apparatus is connected, while insuring continued registration between the indicia imprinted on web and the segments into which said Web is later divided. Further, said driving and connecting arrangement provides a means for continuously rotating die wheel 36 while the segmenting means is stopped to keep the ink stirring and to insure that the ink on the die wheel does not dry out.
  • Web marking apparatus 10 is particularly adapted for connection to a segmenting means and for operation as a slave to the segmenting wheel thereof. Further, the abovedescribed driving and connecting arrangement and said web marking apparatus are particularly adapted for driving a die wheel selected from a group of the wheels of different diameters at a circumferential speed substantially equal to the circumferential speed of the segmenting wheel without regard to variations in the angular velocity of said segmenting Wheel. Particularly, the provision of means for readily removing die wheel 36 for the replacement thereof by a die wheel of a different diameter; the adjustment means for the displacement of impression roller 38, well 40 and doctor blade 122; and the hinged mounting of plate carrying gear 184 on frame 20 to permit the substitution of gears of different diameters for gear 176, constitute substantial advances over the prior art.
  • Apparatus for marking a moving continuous web said web to be operated on by segmenting means having a rotatable segmenting wheel engaging said web for defining a plurality of segments in said marked web, and driving means for rotating said segmenting wheel, which comprises marking means having a rotatable die wheel engaging said moving web for marking same; connecting means operably connecting said driving means and said die wheel for rotating said die wheel at a circumferential speed substantially equal to the circumferential speed of said segmenting wheel, said markings being disposed in predetermined locations on said web for registration with said segments; an override clutch means; and an idler motor coupled to said die wheel through said override clutch means; said override clutch means being adapted to transmit the rotative drive of said idler motor to said die wheel when said segmenting wheel is stopped, and to permit said die wheel to rotate in response to said driving means when said segmenting wheel is rotating, said connecting means including registration means interposed between said die wheel and said driving means for coupling said die wheel and driving means during the rotation of said segmenting wheel, permitting the rotation of
  • Web marking apparatus as recited in claim 1, wherein said segmenting means comprises a strip packaging system, said segmenting wheel being a sealing wheel.
  • marking means includes a frame; a shaft rotatably mounted on said frame, said die wheel being mounted on said shaft for rotation therewith; and a driven means coupled to said connecting means for rotation in response to said driving means, said driven means being removably mounted on said shaft for rotation of said shaft and die wheel, the portion of said connecting means coupled to said driven means being displaceable relative to said driven means to accommodate a driven means selected from a group including driven means of different diameters.
  • Apparatus for marking a continuous web as recited in claim 1, wherein said marking means includes a frame; mounting means for removably supporting said die wheel on said frame for substitution of a die wheel selected from a group including die wheels of difierent diameters, said mounting means being adapted to permit removal of said die wheel in a substantially upward direction; a well for carrying ink, a portion of said die wheel extending within said well for inking the peripheral surface thereof; doctor means engaging the peripheral surface of said inked die wheel for controlling the amount and distribution of ink thereon; a rotatable impression roller pressingly engaging said moving web against said rotatable die wheel; and adjustment means for mounting said well, doctor means and impression roller on said frame for lateral displacement relative to the axis of said die wheel to accommodate a die wheel selected from said group thereof.
  • said registration means includes a shaft coupled to said clutch means for rotation by said idler motor and to said die wheel for rotation thereof in response to either said idler motor or said driving means; drive wheel means having said shaft journaled therethrough and having a pin extending from a side thereof; a latch dog mounted for rotation with said shaft and pivotable into and out of en- 12 gagement therewith; and spring means for biasing said pivotably mounted latch dog against said shaft, said latch dog having a first surface engageable by said pin for rotatably driving said latch dog and shaft to rotate said die wheel in response to said driving means, and a second surface engagable by said pin to pivot said latch dog out of engagement with said shaft to provide clearance for said pin when said drive wheel means is stopped in response to the stopping of said segmenting wheel while said shaft and latch dog continues to rotate in response to said idler motor.
