Definitions

  • the object of this invention is an apparatus that enables the rubber-covered cylinder to be washed and dried mechanically in a short time and with minimum employment of labor.
  • the apparatus in question consists essentially of two side-by-s-ide bands running in closed circuit or elongated loops in a direction parallel to the axis of the cylinder to be washed, said bands, with the outer surface covered with spongy material, being mounted in two frames swinging around an axis parallel to the axis of the cylinder so that by operating an arm integral with said frames either band can alternately be brought in contact with the cylinder, and means being provided to dampen one of the two bands intended for washing.
  • FIGURE 1 shows a cross-section of the apparatus.
  • FIGURE 2 shows a plan view
  • FIGURE 3 shows a detail of the dampening device.
  • FIGURES 4 and 5 show side views along arrows A and B of FIG. 2.
  • the preferred form of apparatus illustrated is made up of a frame formed by a U-flanged plate 1 and an L- flanged plate 2 welded to a coupling 3 that is mounted swingingon two coaxial pins 4-4 fastened to the shoulders of the press, said coupling being provided at one end with arm 5 that can take three positions AB-C to be described below.
  • Both bands 8 and 12 run with one active branch below and in contact with the external planes 1849 of the bottoms of the frame and with the other branch inside said frame, in which two tension rollers 20-21 are set up to regulate the tension of both bands.
  • Members 18 and 19 serve to engage the back sides of bands 8 and 12 so they may be pressed against the surface of the cylinder 30.
  • Washing band 8 is provided with two consecutive dampening devices, each consisting of a hollow roll 23 having radial holes 24 and turning on a pin 25 fastened to frame 1, while through axial hole 26 opposite the one bearing the pin a pipe 27 which pours the washing fluid from the corresponding tank 28 inside roll 23 enters and egresses freely.
  • The. hollow rolls are also cove-red with spongy material.
  • dampening devices there are two dampening devices, one being intended to contain the washing mixture, such as kerosene-benzine, and the other only water. Dampening rolls 23 turn in contact with the spongy covering of the band which therefore receives the fluid coming out of holes 24.
  • a rubber-covered steel scraper blade 29 At the end of the frame and opposite washing band 8 there is mounted a rubber-covered steel scraper blade 29, the slant and distance of which can be regulated to remove the dirty fluid carried by the band which was in contact with cylinder 30 of the press.
  • the means for regulating the blade are mounted inside the frame so that the dirty fluid the blade separates from the band cannot flow off the sides but drops into tray 31 provided with discharge pipe 32.
  • coupling 3 can consist of two semi-cylindrical shells interconnectibly by means of a sliding collar or the like, after they have engaged the two pins.
  • Apparatus for washing and drying the blanket cylinder of an offset press comprising in combination two side-by-side endless absorbent bands, pairs of rollers for supporting and guiding said bands as elongated loops parallel to the axis of the cylinder, a frame pivotally mounted to move about an axis parallel to the cylinder whereby one band or the other may be moved into contact with the surface of the cylinder, means engaging the back sides of the belts for pressing the bands against the cylinder, means for driving one of the rollers of each pair to drive the band-s and means for supplying dampening fluid to one of said bands.
  • the means for supplying fluid to the washing band consists of a fluid supply tank, a perforated hollow roll covered with spongy material and mounted idle on a horizontal pin, into which roll the end of a pipe coming from the fluid tank axially projects, the roll being mounted on the frame so as to turn in contact with the spongy material of the upper reach of the band and to dampen same with the fluid coming out of the holes before it reaches the return roll and passes to the lower reach.
