  • the hard surface, hydrophilic roll is positively rotated to have the same surface speed as the rotating printing plate and the resilient metering roll is driven at a speed which is adjustable to adjust the relative surface speeds between the hard surface, hydrophilic roll and the resilient metering roll to control the amount of dampening fluid delivered to the hydrophilic roll.
  • the present invention relates to a printing press or other apparatus in which a rotating applicator such as a form roll applies a fluid material, e.g., ink, dampening fluid, or both, to the surface of a printing plate or the like.
  • a rotating applicator such as a form roll applies a fluid material, e.g., ink, dampening fluid, or both, to the surface of a printing plate or the like.
  • An important object of the present invention is to provide a new and improved lithographic printing press having a dampening mechanism in which the flow of dampening fluid is controlled by varying the relative surface speed of cooperating rolls in the dampening mechanism and in which the dampening mechanism includes a positively driven roll which runs in engagement with a form roll, the driven roll being driven at the surface speed of the plate to minimize the effect of scumming on the plate.
  • Another object of the present invention is to provide a new and improved lithographic printing press wherein the printing plate has dampening fluid applied thereto by a form roll frictionally driven from the plate with dampening' fluid being supplied to the form roll from a positively driven hard surface transfer roll whose surface speed is the same as the surface speed of the plate cylinder and in which the dampening fluid on the hard surface transfer roll is controlled by varying the speed of a resilient surface running in pressure engagement with the hard surface transfer roll.
  • Another object of the present invention is to provide a new and improved lithographic printing press in which dampening fluid being fed to the printing press is first metered by a roll running in pressure relationship with a variable speed roll having a resilient surface with the amount of fluid being transferred by the dampening mechanism being controlled by varying the speed of the variable speed roll to vary the surface speed between the variable speed roll and a positively driven hard surface hydrophilic roll rotating at a predetermined surface speed, preferably at the surface speed of the plate.
  • Still another object of the present invention is to provide a new and improved lithographic printing press in which a dampening mechanism for feeding dampening fluid to the :printing press has the dampening fluid metered and smoothed out by a resilient surface roll which operates as a pan roll and delivers dampening fluid to a cooperating roll having a resilient surface with the surface speed of the cooperating roll and the pan roll being the same but variable to vary the amount of dampening fluid transferred to a hard surface roll running in pressure engagement with the cooperating roll and having a predetermined surface speed.
  • Yet another object of the persent invention is to provide a new and improved printing press in which a dampening fluid is transferred by a plurality of rolls from a supply therefor to a printing plate and wherein the distribution and amount of dampening fluid is controlled by varying the speed of a roll having a resilient surface to change its surface speed relatively to a hard surface roll with which it has a pressure engagement.

  • the present invention is susceptible for use in various machines where it is desirable to apply a coating of a fluid material onto a moving surface with an applicator roll or other type of rotating applicator but it is particu larly useful to apply dampening fluid to the surface of a printing press plate cylinder.
  • ink and dampening fluid are applied to the printing plate and in the illustrated press, ink is fed to the printing plate through an inking mechanism which includes form rolls 16, 17, 18, 19 which run in engagement with the surface of the printing plate.
  • a vibrating roll 20 is disposed between the form rolls 16, 17 and runs in engagement therewith while a similar vibrator roll 21 engages and runs in contact with form rolls 1'8, 19.
  • a vibrator roll 22 also engages form rolls 17, 18.
  • the vibrating rolls 20, 21, 22 are conventional vibrator rolls having a hard smooth ink receptive metal surface while the form rolls 16, 17, 18 and 19 have conventional resilient surfaces.
  • the ink is fed to the vibrator rolls 20, 21 from an ink fountain 24 by a duct roll 25 and a plurality of ink transfer rolls shown in the drawing.
  • the train of ink rolls shown for supplying ink to the form rolls is that of a conventional inker and therefore will not be described in detail.
  • dampening fluid is applied to the plate on the cylinder by a dampening mechanism which feeds the dampening fluid through the first form roll 16 which is larger than the other form rolls.
  • the dampening mechanism includes roll 28 having a hard hydrophilic, smoothly finished surface, preferably chrome, which rotates in pressure relationship with the first form roll 16, a resilient surface variable speed roll 30 which runs in pressure relationship with the hard chrome roller 28 and a cooperating metering roll 31 having a resilient surface and rotating in a pan 32 containing the dampening fluid.
  • the metering pan roll 31 picks up dampening fluid from the pan 32, transfers it to the roll 30, which in turn transfers the dampening fluid to the chrome transfer roll 28 running in engagement with the first form roll 16 to feed the dampening fluid to the form roll and from the form roll 16 to the plate.
  • the roll 30 is driven at a speed which is variable to vary the relative surface speeds of the metering roll 30 and the chrome transfer roll 28.
  • the variable speed metering roll 30 and the metering pan roll 31 are driven to rotate at the same surface speed.
  • the metering pan roll 31 is rotated at the same surface as the metering roll 30 but this surface speed is variable to control the amount of fluid transferred between the roll 30 and the roll 28 which rotates at a fixed surface speed for a given press speed.
  • the rolls 28, 30 and 31 each preferably rotate in an opposite direction to the roll or rolls which it engages, but the rolls 30, 31 may be driven so that the roll 30 rotates in the same direction as the chrome roll 28.
  • the chrome transfer roll 28 is positively driven from the plate cylinder and is rotated at the same surface speed as the plate cylinder.
  • the vibrator roll 20 is also positively driven from the press at the same surface speed as the plate cylinder in a conventional manner and the form roll 16 is frictionally driven from the vibrator roll 20, the chrome transfer roll 28 and the plate cylinder.
  • the chrome transfer roll 28 is shown as being driven from a gear 33 which is on the plate cylinder and rotates therewith.
  • the gear 33 drives a gear 34 which drives a shaft 37 through bevel gears 35, 36.
  • the shaft 37 is connected by bevel gears 38, 39 to drive a shaft 40 which in turn drives a shaft 41 through a clutch 42.
  • the shaft 41 has a bevel gear 43 thereon which meshes with a bevel gear 44 on the shaft of the transfer roll 28.
  • the spline connection of the gear 43 allows the transfer roll 28 to be moved into and out of engagement with the form roll 16 while maintaining a drive thereto.
  • the chrome roll is preferably driven at the surface speed of the plate cylinder to frictionally drive the form roll 16 at this speed to thereby prevent any drag on the form roll which may occur when a roll which runs in engagement therewith rotates at a slower surface speed.
  • variable speed metering roll 30 is driven by a variable speed motor 45 through a positive drive shown as a chain drive 45a.
  • a chain drive 45b may also be used to drive the metering roll 31 from the roll 30 to rotate them in a 1 to 1 relationship so that they have the same surface speeds.
  • the chrome transfer roll 28 and the form roll 16 are of the same length but the metering roll 30 is longer than the chrome transfer roll 28 so as to extend beyond the opposite ends thereof.
  • the pressure relationship between the metering pan roll 31 and the metering roll 30 is adjustable to smoothly meter the flow of dampening fluid between the nip of the rolls to provide an evenly distributed thin film of dampening fluid on the roll 30.
  • the pan metering roll 31 preferably has shaft portions extending from the opposite ends thereof to be supported in bearing blocks which may be moved toward and away from the metering roll 30 to adjust the pressure relationship between the rolls 30, 31.
  • Bearing blocks of this type are conventional and well known in the art and a simplified bearing support for the roll 31 is shown in FIG. 5. As shown in FIG.
  • the shaft portion 31a extending from one end of the roll 31 is received in a self-centering bearing 46a in a bearing block 46 which is supported in an inverted U-shaped recess in a guide block 47 mounted on a support member 48 of the frame F of the press.
  • the open end of the U-shaped recess is closed by a plate 50 and a pressure adjusting bolt 50a is threaded through the plate 50 to engage the bearing block 46 and is adjustable to move the roll 31 upwardly into an adjustable pressure relationship with the roll 30.
  • the mounting block 47 is mounted onto the support member 48 by screws 47a which are received in elongated slots in the mounting block to allow the mounting block 47 and the bearing block 48 to be shifted laterally, i.e.
  • the mounting block 47 is shown as being adjustable laterally by the operation of a plurality of adjusting screws 51. Since the metering pan roll 31 is supported at both ends by the same type of support the metering roll 31 can be moved to a skewed position relative to the roll 30 as is best shown in FIG. 7.
  • the bearings 46a at each end of the roll 31 pivot in the respective block 46 to accommodate the skewing of the re A skewed position for the metering roll 31 is advantageous to obtain a thin evenly distributed film on the roll 31.
  • the roll 31 may be a crowned roller as indicated in FIG. 8.
  • the roll '31 tapers in an arcuate manner from the central portion thereof to the ends so that when the pressure relationship is established between the rolls 30, 31, the rolls engage over an area of substantially constant width.
  • the area of contact is a narrow strip extending the length of the rolls 30, 31.
  • crown may be determined empirically and varies in accordance with the length of the roll and its strength and in accordance with the materials involved.
  • a crowned roll may be used in combination with skewing or in lieu of skewing.
  • the resilient roll 30 and the chrome roll 28 also run in pressure relationship and this relationship may be adjustable by the use of movable bearing blocks similar to those on the roll 31.
  • the form rolls 17, 18 and 19 are supported for movement to an inker off position in a conventional manner while the form roll 16 is moved from its position against the plate by operation of the dampening mechanism.
  • the dampening mechanism as a whole is supported for movement toward and away from the cylinder to move the chome roll 28 into and out of engagement with the form roll 16.
  • a roller 55 on a pivoted actuating arm 56 may be swung to the position shown in FIG. 1 to move the dampening mechanism from the position shown in FIG. 2 to establish the pressure relationship between the relative positions of the chrome roll 28 and the form roll 16 shown in FIG. 1.
  • the roller engages an adjustable plate 57 on the dampening mechanism to move the latter against the action of a spring 60.
  • Stops 61, 62 may be provided to limit the movement of the arm between the inker on and inker olf position. In its on position, the pivoted arm 56 is in a dead center or locking position slightly over dead center. Adjustment of the plate 57 determines the on position of the dampener and the pressure relationship between the rolls 16, 28.
  • the arm '56 is rotated to allow the dampening mechanism to be moved away from the impression cylinder by the spring 60.
  • the form roll 16 is mounted for limited movement about the axis of the vibrator roll 20.
  • the dampening mechanism When the dampening mechanism is moved to clear the chrome roll 28 from the form roll 16, the form roll is moved by a spring 65 against a stop 66 to move the form roll out of engagement with the plate cylinder.
  • the dampening mechanism When the dampening mechanism is again moved to its operative position, the chrome roll 28 engages the form roll 16 and moves it against the spring 65 to a position against the plate cylinder and against a stop 67 which limits the pressure that the form roll may apply to the plate cylinder and provides a resisting force to the chrome roll 28 to establish a pressure relationship between the chorme roll 28 and the form roll 16.
  • dampening mechanism can be operated when the mechanism is in its retracted position to form films on the rolls of the dampening mechanism and to cause the chrome roll 28 to be operating at press speed when it is moved into engagement with the form roll.
  • the dampening mechanism can be moved to engage the form roll 16 with the chrome roll 28 rotating at the surface speed of the press, prior to the form roll engaging the plate. This enables the form roll 16 and the chrome roll 28 to be rotating at their proper speeds when the form roll 16 engages the plate.
  • the chrome roll 28 will be driven at its proper speed when it is moved into engagement with the form roll 16 and the form roll 16 will be driven from both the vibrating roll 20 and the chrome roll 28. This will also keep the form roll 16 rotating at a surface speed corresponding to the surface speed of the plate cylinder when the gaps in the cylinder 10 are moving past the form roll 16.
