GEORGE SIMPSON, OF PATERSON, NEW JERSEY COMBINED COLOR AND FLOCK PRINTING MACfiINE Application filed April 24,
P My invention relates more particularly to a textile printing machine, which is adapted to print a pattern or design in one or more colors with which there .is associated a flock 5 printing pattern or design .said color pattern and the flock pattern eing always applied in proper register, by a continuing oper ation of printing from successive synchronized printing rolls cooperating with the same impression or platen cylinder;
The method-"of flock printing employed has been to run the fa heretofore ric through a printing machine for printing the color at- 3 tern and then run it through a separate ock printing machine for printing the flock printing pattern. But the difficulty with this method is that it is almost impossible to ma1n- .tain the flock printing pattern in proper register with the previously printed. color pattern or design. The result is that only a few yards can "be doneata time forthe pattern soon gets out of register, and then the cloth and flock printing roll mustbe adjusted to obtain better registration of the pattern. This causes delay and added expenSe and the work turned out Is imperfect and unsatisfactory.
Therefore, the object of my improvedmethod is to simultaneously complete the color and flock printing designs or patterns, asa continuing operation over the same platen cylinder, so that the color pattern and flock pattern, once brought into register, are
applied successively to the fabric under the 85 same conditions so that proper. register of the attem is maintained without diff culty.
' Thus,.since the entire job is completed 1n one operation by passing the fabric through one machine, there is a considerable saving 1n time and cost. A
.A'further object in my lmproved printing machine is to provide means for mde- 'pendently adjusting-the flock printing roll to bring the pattern thereof into register with ii the pattern or design printed by the color printing rolls.
These and other objects Wlll be more particularly brought out in describing my improved machine, one form OfWlllCll is shown i0 in the accompanying drawings. Fig. 1 is a that the 1924. Serial No. 708,612.
side elevation ofthe upper part of my printing machines, showing the flock printing roll and its bear ngs in section longitudinally of the roll; Fig. 2 is an end elevation with parts of the frame broken away; Fig. 3 shows an '55 enlarged section of the flock printing roll of Fig. 2, and Fig. 4 shows a detail of the adusting device for the doctor blade.
eferring to the drawings, it will be seen usual impression or platen cylinder 1 is mounted in bearing blocks 2, which are slidably supported in the end frame members Any suitable number of color printing rolls 4 (in the present machine three are shown) may be mounted in adjustable beare5 ing; blocks, slidably mounted on Ways 5, formed in the end frame members 3 and extending radially of the main cylinder 1. The usual screws 5 are provided for regulating the pressure of the color rolls on the cylinder 1. Each of the color printing rolls 4 is mounted u on an arbor 6, to one end of which aworm wiieel 7 is secured. A worm 8, cooperating with the worm wheel 7 isyrotatably mounted on the face ofthe usual fitting gear 7;; or pinion '9, concentric with the worm wheel 7 and rotatablejrelative. thereto, thus providries the cloth or fabric to be printed through the machine. o
The machine as thus far described may be of the usual construction of. the ordinary multicblor textile printing machine, and in adapting the machine for carrying out my method,-brackets 12 are mounted upon each of the end frame members 3, for supporting a dock printingroll 13 directly above the platen cylinder 1, as will be seen in Figs. 1 and '2. The brackets "12 are provided with are adjustably mounted." Screws 16 and hand wheels 17 are preferably mounted, between caps 18 of the brackets 12 and the hearing blocks 15, for adjusting the flock printing roll 13 toward and from the cylinder.
The flock printing roller 13 is preferably formed of a thin 'walled copper cylinder; which is-perforated over its entire surface by small holes arranged to form the pattern A to be flock printed upon the cloth. The ends of the copper cylinder preferably may be provided with flanged rings 19 secured by screws 20 to tubular bearing thimbles 21 and 22. The latter are supported by ball bearings 23 in the respective bearing blocks 15, so that the roll 13 is freely rotatable. In order. that the flock printing roll 13 may rotate in synchronism with the color printing rolls 4, the bearing thimble 22 is provided with fitting gear or pinion 24 meshing with the crown wheel or intermediate gear 10. For adjusting the design or pattern of the flock printing roll to register with the color pattern on the fabric the pinion 24 is loosely mounted and provided with a worm 25 meshing with a worm wheel 26, keyed to the outer end of the bearing thimble 22, substantially as shown in For ejecting or forcing the size, varnish, paint or other suitable flock printing material through the holes, forming the design or pattern on the flock printing roll 13, any suitable means may be employed but preferably this is done by the usual doctor. In the present instance, T preferably mount within the flock printing roll 13 a doctor blade 27 on a doctor shear 28, provided with pivot rods 29, extending, parallel to the axis of the roll,'through the end thimbles 21 and 22 thereof. The outer ends of the rods 29 are preferably pivoted in bearings 30 on the ends of arms 31 secured by nuts 32 to studs 33, secured to and projecting from the respective" bearing blocks 15,. as shown in Figs. 1, 2 and 4. The position of the doctor blade 27 relative to the inner wall of the flock printing roll 13 is preferably regulated by screws 34 mounted in lugs 35, located on the pivot bearings 30, (see Figs. 2 and 4-). The ends of the screws 34 engage lugs 36 on arms 37 the latter being secured to the pivot rods 29 and located adjacent the pivot bearings 30, so as to hold the doctor in proper position within the flock printing roll 13. The arms 37 prefeiably have cords 38, attached thereto, which extend over pulleys 39 and carry weights 40, thereby providing resilient means for holding the doctor in adjusted position and for lifting it when the screws 34 are adjusted outward relative to the lugs To supply the interior of the flock printing roll 13 with the size, paint or material to be forced, by the doctor blade 27, through the pattern of the roll, apipe 41 (Fig. 1) preferably extends axially of the flock printing roll and is provided with a plurality'of slots 42, or other suitable openings, through which the material escapes and falls to the lower side of the flock" roll. One end of the pipe 41 is closed by a cap 43 and the other is preferably connected by means of a pipe 44 with a supply or storage tank 45, from which the flock printing material may be forced by com pressed air .or fed by gravity; the quantity of material passing to the pipe 41 being regulated by a valve 46.
From the foregoing, it will be understood that in the operation of my improved color and flock printing machine, it is clothed and power operated, substantially the same as the ordinary textile color printing machine. That is, the impression or platen cylinder 1 is suitably padded and then the blanket, the grey or backing cloth, and the cloth to be printed are threaded between the platen cylinder 1 and the color printing rolls 4 and then between the cylinder and the flock printing roll 13. The three cloths as threaded through the machine are indicated by dotted lines in Fig. 2, and the direction of feed there of by arrows. After the cloths are threaded into the machine, the various printing rolls 4 and 13 are adjusted toward the cylinder 1 to exert the properpressure for printing, and if necessary, the color printing rolls are adjusted by the worms 8 to get the color patterns in register and then the flock printing roll 13 may be adjusted, by the worm 25, to bring the pattern thereof into register with the color pattern. After the flock printed cloth leaves the machine, it is carried horizontally for some distance during which time flock powder is sprinkled over the flock printed design or pattern, and treated and finished in the usual manner.
It will be understood that while I have described one form of printing machine for carrying out my improved method of color and flock printing, 1 do not wish to be limited to the construction shown, for various modifications therein may be made without departing from the spirit and scope of the invention,
