Definitions

  • the present invention relates to a dye printing apparatus, in general, and to a multiple dye feeding to the printing cylinder of a particular.
  • FIGURE 1 is a fragmentary elevation, partly in section, of the outlet portion of a multiple-dye attachment, together with a doctor blade and a portion of the printing cylinder, the rear portion of the multiple-dye attachment being broken off;
  • FIG. 2 is a rear elevation of the printing frame with the multiple-dye attachment
  • FIG. 3 is an end View of the printing frame with the multiple-dye attachment.
  • the multiple-dye attachment 13 is subdivided into a plurality of separate compartments and at the front end of each of the partitions fitting members 1 are provided, which have a concave front end face and fit closely the printing cylinder 2.
  • the bottom of the attachment 13 has secured thereto a resilient blade 3, which is capable of resiliently adjusting itself to bulges and vibrations of the rotating printing cylinder 2 when applied thereto.
  • the resilient blade 3 does not extend as far as to the surface of the cylinder 2, but leaves a clearance 4, which is closed by a conventional doctor blade 5.
  • the doctor blade 5 scrapes the surplus dye from the printing cylinder 2, the surplus dye is returned through the small gap 4 into the corresponding dye chamber.
  • a slide 6 extending throughout the length of the attachment serves the purpose to regulate the width of the gap 4 and is roller dye printing apparatus, in
  • the slide 6 and the leaf spring 8 are formed with slots 9, through which the bolt 7 extends to serve as a guide pin when the slide 6 is pushed forwardly against the cylinder 2.
  • the leaf spring 3 is turned in at its rear end to form an open ring serving as a support and stop for the slide 6.
  • the blade 3 is held in its desired position by a clamping rail 10.
  • the resilient support 11 on the underside of the slide 6 ensures a good seal between the doctor blade 5 and the edge of the slide 6.
  • the adjustable bearing means for the multiple-dye attachment 13 is disclosed in FIGS. 2 and 3.
  • the multiple-dye attachment 13 is held in position between two bearing plates 14 and a clamping stirrup 15; the bearing plates 14- and the clamping stirrups 15 are interconnected by bolts 16.
  • the bearing plates 14 support the multiple-dye attachment 13 only at its outer ends. This enables a deflection of the attachment 13 under the influence of a deflected printing cylinder 2. This deflection may be adjusted by a set screw 19 mounted on the clamping stirrup 15.
  • the clamping stirrup 15 comprises two laterally protruding pivot pins 2%, each of w ich extends into an elongated slot 22. of the side parts 21 of the bearing frame.
  • the elongated slots 22 extend substantially in the direction of the pressure applied to the cylinder 2 and have on the side remote from the cylinder 2 a downwardly protruding portion 22 and at the top an opening 22 for introducing and removing, respectively, the feed system.
  • the multiple-dye attachment 13 is forced against the cylinder 2 by sleeves 23 pivoted by means of pins 27 to the side parts 21 of the frame and screw bolts 26, the latter being in engagement with inner screw threads and acting by means of a compression spring 25 and a loosely inserted bolt 24 on the pivot pins 29.
  • the set screw 26 is turned.
  • the coarse adjustment is effected by means of screw bolts 28 attached to both sides of the frame and nuts 29 affixed to the frame base 3th for the side parts 21.
  • a hugging pressure is exerted by two adjustable tension springs 31, which act on the rear edge of the bearing plate 14 at a point which is eccentric with respect to the bearing pins 29 and bring about a lever action which forces the outlet portion 32 towards the cylinder 2 in a direction opposite to that of rotation thereof.
  • fitting templates 33 can be applied on both sides. The guidance of the multiple-dye attachment 13 by means of the bearing pins 2%?
  • the set screw 26 is turned back on both sides to reduce the pressure on the pin 24, until the sleeves 23 can be swung about their pivot 27, whereby the pivot pins 20 are displaced in the elongated slots 22.
  • the entire multiple-dye attachment 13 with the clampi g stirrup 15 and the bearing plates 14 is then retracted by hand, the two pivot pins 20 being received and locked in the downwardly inclined protruding part 22 of the elongated slots 22.
  • the bottom of the multiple-dye attachment 13v slides along the top edge of the rail 34 of the bearing frame 21.
  • the multiple-dye attachment 13 is axially retained by clamping rings 35 provided on the pivot pins 28.
  • the reservoir 36 having plurality of compartments, is loosely mounted on the multiple-dye attachment 13.
  • the compartments of the former are connected to the compartments of the multiple-dye attachment 13 by a rod valve 37, which tightly bears on the attachment 13 under the action of the weight of the reservoir.
  • the pressure reduction due to the loss of weight resulting from the consumption or" dye would be effective by the lever action at the pivot pins 20 on the outlet portion 32.
  • the rod valve 37 may also be applied close to the stub shaft 20. Another compensation can be efiected by supporting the reservoir 36 below its center of gravity.
  • the illustrative embodiment shown relates to the application of the device to the last rollers of a roller printing apparatus. Some arrangements must be laterally inverted when the device is to be applied to the material input side of the printing apparatus.
  • a printing cylinder a dye attachment including a doctor blade, both said dye attachment including said doctor blade extending over the length of said cylinder
  • said present invention residing in the fact that said dye attachment is a multiple-dye attachment having a bottom portion and including said doctor blade, said multiple-dye attachment being resiliently defiectablc in the longitudinal direction of said printing cylinder and resiliently adjusting to a bulge of said printing cylinder in its longitudinal direction, and said bottom portion of said multiple-dye attachment being connected longitudinally with at least one resilient blade defining a gap between the longitudinal edge of said blade and said printing cylinder, and said doctor blade bridging said gap.
  • the apparatus as set forth in claim 1, which includes a slide disposed between said resilient blade and said doctor blade, said slide being resiliently deflectable in longitudinal direction of said cylinder and movable in the direction of escape of said dye for closing said gap.
  • the apparatus as set forth in claim 1, which includes at least two oppositely disposed bearing plates supporting the ends of said. multiple-dye attachment, said bearing plates having an intermediate part which is deflectable and is adaptable to any deflections of said printing cylinder.
  • said multiple-dye attachment comprises a plurality of compartments and includes a removable reservoir having a plurality of compartments, and a rod valve in said reservoir adjacent said multiple-dye attachment, said rod valve connecting each of said plurality of compartments of said reservoir to a corresponding one of said plurality of compartments of said attachment, and said rod valve comprising a rod resting sealingly 'on said multiple-dye attachment and liftable therefrom.
