  • FIG. 7 is a fragmentary view of the roller of FIG. 1 illustrating a modification incorporating the distributors of FIG. 4.
  • an inking roller 10 in accordance with the invention comprises a cylindrical outer shell 12 of a porous material and closed at opposite ends by respective non-porous caps 14, 16.
  • the roller is mounted, by means of oil seals 18, one in each end cap l4, 16, on a central spindle or shaft extending through and coaxial with the roller shell 12.
  • the interior of the shell I2 is partially filled with wadding in the form of several rings 22 of felt or other ab sorhent material. for example expanded polystyrene.
  • the rings 22 are arranged coaxially within the shell 12, the outer peripheral surfaces of the rings abutting the inner surface of the shell. and the inner peripheral sur- 2 faces of the rings lying concentric with, but spaced from the spindle 20.
  • the spindle 20 is hollow for at least part of its length from one end to a position within the shell 12, the hollow portion 24 of the spindle within the central part of the shell 12 being perforated at apertures 26.
  • a disc 30 of rubber or other resilient material seals the spindle at one end of a portion 32 which extends beyond the end cap 16.
  • the disc 30 is slotted to permit insertion of an ink injection nozzle 40 into the interior of the spindle.
  • the rings 22 are packed into the shell and the end caps l4, 16 are snapped into the end portions of the shell 12.
  • the end caps l4, 16 are then located on the spindle and are retained relative to the spindle by circlips 42 which engage in annular grooves 44 of the spindle.
  • the ink injection nozzle 40 for example the needle of a graduated syringe 46, is inserted into the slot in the rubber sealing disc 30 and a measured quantity of ink is injected into the spindle.
  • the slot automatically re-seals itself.
  • the ink flows along inside the spindle and enters the interior ofthe shell through the perforations 26 in the spindle 20, the annular-section chamber formed between the inner peripheral surfaces of the rings 22 and the surface of the spindle constituting an ink reservoir.
  • Ink within the reservoir is absorbed from the reservoir by the rings 22 and is fed thereby to the inner surface of the porous shell l2, the ink passing through the shell to its outer surface in a controlled manner under the effect of capillary action.
  • the reservoir can be re-charged by injecting a further measured quantity of ink into the hollow spindle 20.
  • the shell 12 is formed from porous, high density, sintered polyethylene with a pore size of between l00 and 300 microns and a thickness of 3.2 mm (1/8 of an inch).
  • Felt forms a particularly suitable wadding in as far as it has good absorbency characteristics enabling rapid ink flow both radially and axially of the roller, while being sufficiently retentive to ensure controlled flow from the ink reservoir to the shell.
  • the interior of the shell can be filled with glass or other balls suitably having a diameter of between (0.50 and 0.75 mm) 0.02 and 0.03 inches.
  • the balls are retained in position by axially spaced annular baffles.
  • the ink used to fill the roller is a liquid ink having a suitable viscosity to allow injection filling.
  • the arrangement comprises an inner sleeve 48 having apertures 50 each having a diameter of approximately 1.6 mm (l/l6 of an inch) and these are distributed as indicated in FIGS. 3A to SE at positions 1, 2, 3 and 4.
  • An outer sleeve 52 has a single row of aligned apertures 54 each approximately 0.8 mm diameter 1/32 of an inch). As illustrated all apertures 54 will be aligned with apertures 50 of the sleeve 48 and so all parts of the roller will be supplied with ink. If a knob 56 at the end of the sleeve 48 is rotated anti-clockwise through 90 there will be no flow to the central aperture 54 and to the apertures 54 to the right thereof.
  • the knob is rotated anticlockwise through a further 90, then the left-hand and right-hand end apertures 54 will receive no ink and the central three apertures will be supplied. A further 90 rotation will result in closure of the two apertures 54 at the left-hand end portion and the central aperture, while the two right-hand end apertures will be open.
  • the respective apertures 50, of each set of apertures associated with a single aperture 54 are angularly spaced. Alternatively however the respective apertures of each set can be axially spaced whereby the ink distribution can be varied by an axial push-pull movement of the knob 56 or of the sleeve 52.
  • An ink distributor 60 shown in FIG. 4 comprises an annular member 62 carrying outwardly-directed radial arms 64 each formed with a passage 66 extending lon gitudinally thereof.
  • Each distributor is mounted as shown in FIG. 7 within the shell 12 with the roller spindle 20 extending through the annular member 62 so that the inner end portion of each arm (and thus of the passage) lies within the ink reservoir fed from the apertures of perforations 26.
  • the outer end 68 of each arm is spaced from the inner surface of the shell 12 preferably by about 3.2 mm l/S ofan inch) so that the distributor acts to feed ink directly from the reservoir to the absorbent material 22 adjacent the inner surface of the shell 12.
  • a number of such distributors can be arranged spaced axially within the shell as shown in FIG. 7.
  • the distributor can be in the form of a plastics or metal molding consisting of two identical parts. joined together in a median plane extending at right angles to the axis of the annular member 62, by means of interengaging studs and recesses on the adjacent faces of the two parts.
  • the distributor has five arms 64 evenly arrayed about the axis of the annular member. the arms having an outer diameter of mm and the passages therein having a diameter of 3mm.
  • the ink distributors 60 can be assembled from their two identical parts with the aid of the device illustrated in FIG. 5.
  • the parts themselves are conventional thermoplastics moldings and further details of the molding process need not be given.
  • the device is capable of assembling. in stages. a plurality of distributors as shown in FIG. 4 and comprises an elongate base 70 having a central upright member 72 and a pivot assembly 74 which carries a shaft 76 arranged to receive. with a free sliding fit, a plurality of distributors 60 in their dis-assembled parts form.
  • the parts are held in position by end plates 78, 80 which have cut-outs 82, 84 for a purpose which will appear hereinafter.
  • the base 70 carries on one portion of the member 72 an elongate support bar or rod 86 which serves to support the shaft 76 whilst the distributor parts are being loaded on to the shaft 76.
  • the opposite portion of the base 70 carries a heated bar 88 which is substantially symmetrically arranged about the member 72 with respect to the support bar or rod 86. It will be apparent that the cut-outs 82, 84 of the end plates 78, 80 are complementary to the upper surface of the heated bar 88.
  • the bar 88 is heated by an electrical heating element.
  • a control knob 90 of which is conveniently mounted in the base 70.
  • FIGS. 6A to 6C The operation of the device is illustrated in FIGS. 6A to 6C.
  • distributor parts are threaded on to the shaft 76 face-to-face and once a load is completed the end plate is replaced and locked in position. for example by a circlip (not shown J.
  • the shaft 76 is then pivoted about the upright member 72 (FIG. 6B) and the distributor parts are engaged in a first position on the heated bar 90 which is of appropriate cross-section.
  • the shaft 76 is pivoted anti-clockwise (as shown) through a small angle and the distributors are then rotated in unison to a second position.
  • the distributors are then placed on the heated bar 88 in this second position and. after sealing has taken place.
