Definitions
- the present invention relates to a device for process-- ing webs of textile fabric and other materials, according to which processing operations known per se are carried out in a single operation while the material passes through the device in a continuous manner.
- FIG. 1 diagrammatically illustrates a cross section through a new processing device according to the present invention for processing textiles and other materials.
- FIG. 2 illustrates a view of FIG. 1 as seen in the direction of the arrow A.
- FIGS. 6 to 15 diagrammatically illustrate the working positions of the individual parts of the multi-purpose processing machine during the various processing operations carried out thereon. 7
- FIG. 16 illustrates in form of a perspective view further details of the, arrangement according to the invention.
- the machine according to the invention makes possible the simplest as well as ing merely minor and quickly effected adjustments of machine elements.
- the machine according to the present invention also makes it possible to carry out completely new types of multi-phase operations which could not be realized on heretofore known machines, as for instance warp printing in combination with sizing, dyeing and printing and simultaneously therewith fixing ;the dye and the print.
- the motor driven drive shaft has associated therewith Va tiltably journalled processing roller which is adapted to be subjected to various pressures, said processing roller being exchangeable for at least another processing device or printing roller.
- said drive shaft has associated therewith at'least one working group comprising a driven shaft and a squeeze roller carried along by the latter, and also a liquid container.
- the processing roller cooperating with the drive shaft is advantageously exchangeably'journalled on a tiltable lever which is adapted under a desired high pressure to. rest against the drive shaft.
- two working groups are provided in the machine together With the liquid containers associated therewith.
- the arrangement is such that one working group is located in the upper half of the machine whereas the other working group is located in the lower portion ranged symmetrically with regard to a central plane and when the rollers of each roller group are substantially identical to each other.
- the groups of rollers may also be preceded or followed by so-called spreader arms or rods in such a way that the webs of materials are fed to each roller group in a certain predetermined direction.
- each roller group is preceded by a special roller on which the material to be processed or a back gray cloth is wound up.
- a dust removing device which may be provided with a brush known per se and a suction device, the effect of which may be improved by an electrifying apparatus.
- This dust removing device has the purpose, prior to the first processing operation, to remove any impurifications such as fibers or the like from the web to be processed.
- laterally sealed squeezing gaps are provided between said individual rollers where likewise a humidifying, wetting, coating, or other chemical treatment of the goods maybe effected.
- a further important feature of the multi-purpose processing machine according to the invention consists in the small space required by said machine. This advantageous feature is obtained primarily by journalling each of the rollers on a shift lever, while two shift levers in the same direction are actuated by a power accumulator only such as a pressure cylinder.
- a power accumulator only such as a pressure cylinder.
- the pressing rollers located in front when considering the direction of movement of the material have associated therewith a preferably manually operable adjusting device.
- the processing roller associated with the drive shaft may, depending on the particular processing operation to be carried out, have associated therewith a simple squeezing roller, a heated calender, a multi-dye roller with solid dye.
- the processing roller journalled on the tiltable lever operable by a power cylinder may be exchanged for a rouleau or roller printing basket in which for instance two rouleau printing cylinders are mounted with chassis and doctor blade as well as a pattern register adjusting device.
- the lower printing roller of the two printing rollers journalled in the rouleau printing basket has associated therewith a separate accumulator which presses these pressing or printing rollers against the drive shaft proper of the machine.
- a motor driven trueing or dressing device is mounted on that tiltable lever arm in which the various processing rollers may be journalled in exchangeable manner.
- This trueing or dressing device has associated therewith a drive motor which latter after tilting out the processing roller with tilting shaft, will drive on one hand the support of the trueing device and on the other hand the color roller or printing roller to be dressed.
- the dressing device permits a dressing or trueing of the color roller in order to eliminate unevenness which might form due to uneven wear of the individual dye layers of the roller during the printing operation.
- the multi-purpose processing device may be operated in different manners by simple adjustment of individual parts thereof.
- one-phase processing operations such as dyeing, permeating, printing, impregnating and the like, may be carried out by said multi-purpose processing machine.
- webs of goods may be coated unilaterally or may be glued together to another web ,of goods.
- one and the same web of goods will during a single passage through the machine successively be subjected to different one-phase operations.
- a web of goods to be processed may first be moistened, then be impregnated in a different phase, and subsequently be provided with multi-color print.
- bined operations on one and the same machine during one and the same passage of the goods to be processed cannot be carried out on any of the heretofore known devices of the type involved.
- the processing operations which will be set forth below are merely examples of an almost infinite number of other possibilities of application of the machine. These possibilities from the simplest one-phase operation to the most complicated combined operation may be varied merely by a slight adjustment in the machine.
- FIG. 1 shows a multi-purpose processing machine designed as multi-color-printing machine of the so-called Devina printing machine type.
- FIG. I mounted on the left-hand side of the machine (with regard to FIG. 1) are two rollers W1, W2 having wound thereon the fabric material which is to be fed through the machine.
- the lower roller W1 contains the fabric material St to be processed, whereas the upper roller W2 has wound thereon the back cloth M.
- a device E for withdrawing dust from the goods.
- the material to be processed passes through the dust withdrawal device E via a roller or bar 2 to the lower three-roller-Foulard A1.
- the intermediate roller 4 of the three rollers 50, 4, 6 is driven.
- the goods are passed between the left-hand roller 50 and the intermediate roller 4 and then move through a liquid container or trough 3.
- the goods St are wetted by a liquid which may consist of pure water or a chemical.
- the goods are passed over a deviating roller 3a in the liquid container 3 and then pass over a spreader or roller 5.
- the goods are squeezed between the right-hand roller 6 and the intermediate roller 4.
- 'Aftr leaving the squeezer rollers, th goods pass over a spreader or roller 7 and a deviating roller 8 to the driving roller or cylinder 9, the so-called press cylinder and then around the dye cylinder 10.
- the roller 10 has associated therewith two further pressing rollers 11 and 12 for purposes of increasing the looping angle, each of said rollers 11 and 12 being individually pressed against roller 10 by separate pressing means, such as the pressing cylinders 31, 32 and levers 11a, 12a.
- the dye roller 10 which may also be called printing roller
- the goods are approximately vertically conveyed in upward direction and are then passed through a drier not shown in the drawings.
- the upper roller W2 carries a follower material M which is passed over a roller or bar 15 and from there moves between the squeezer rollers 16 and17 into a trough 18. From here the material M is passed over roller 19, between squeezer rollers 17 and 20 and over roller 21 to the press cylinder 9.
- the follower material M passes around the rollers 9 and 10 in the same manner as the goods St, however on the'back side thereof This possibility of carrying out so-called com-' sothat the follower material is printed upon only on the.
- the follower material M also takes care that the dye protruding beyond the printing Width on printingroller will be worn up to the same extent as that on the intermediate roller portion which prints upon the goods St.
- Thefollower material M then likewise moves upwardly and, more specifically, is deviated toward the left from printing roller 10 below the drier because the follower material does not have to be dried. After about 300 yards of the goods have been printed upon, the dye roller is worn olf irregularly because, not all dye concentrations are uniformly conveyed to the goods.
- the shift lever 22' has mounted thereon a trueing device B which includes two supporting bars B1, B2 and a draw spindle Z which moves the support or carriageSu mounted on the supporting bars B1, B2 toward the left and toward the right.
- Said support or carriage Su is shown in FIG. 2 and is driven by a motor I drivingly connected to two shafts Ia, lb.
- Shaft Ia at the left side of motor I drives the draw spindle or feed spindle Z of the carriage Su of the honing device .13.
- the feed spindle Z is automatically turned off when the carriage Su has reached its end position and has to be turned on anew while the direction of rotation has to be reversed.
- Shaft Ib on the right-hand side of motor I drives the printing roller 10 when the latter is tilted outwardly (see FIG. 3) and is to be trued.
- FIG. 3 shows a cross section through the machine with the tilting frame 22 in tilted-out position.
- This tilting is' effected by means of a power cylinder, preferablya compressed air cylinder 23.
- a power cylinder preferably a compressed air cylinder 23.
- motor I and trueing device B are tilted.
- motor I mounted on the' tilted frame 22 is turned on through the intervention of switch SH shown inFIG. 2.
- Motor I is a threeephase. pole reversible motor and thus is adapted to rotate at obtained.
- By means of the knurled hand wheel 24 knife" 25 may be moved against the printing roller 19.
- a preferably hydraulically effective brake 23' is required which is actuated in steps.
- the piston of said hydraulic brake cylinder 23' passes-s by certain bores in the wall of said cylinder, the oil stream passing from the front to the back of the piston is decreased or increased as to its cross section.
- the upper roller 11 and lower roller 12' are pressed against the printing roller 10 by means of two preferably likewise pneumatically effective pressure cylinders 31 and 32, cylinder 31 acting upon the upper pressure roller 11 and cylinder 32 acting upon the lower pressure roller 12. Therefore, when tiltable frame 22 is to be tilted outwardly for tr-ueing or changing roller 10, frame 26 has to be lifted. To this end, first the two pressure rollers 11 and 12 are lifted off the printing roller 10. As soon as this has been done, the cylinder 28 is subjected to compressed air so that the entire tiltable frame 26 tilts upwardly by an angle of approximately 90. When 6 the tiltable frame 26 is in its upper tilted out position shown in FIG. 3, the two rollers are tilted into their stretched position so that the goods St move upwardly and the follower material M can not be displaced from its substantially vertical withdrawing direction.
- the motor employed for driving the trueing' device B and for simultaneously driving the dye roller 10 to be trued has a still a further task.
- This additional task consists in driving the dye mechanism ofthe rouleauprinting basket 33.
- the basket 33 according to FIG. 4.
- two copper intaglio printing rollers 34 and 35 have to be fed with dye.
- two dye feeding means are provided which pick up the dye from troughs 36 and 37 and respectively convey the dye uniformly through brushes 38 and 35 to a distributing roller 40 and 41 respectively which in their turn convey the dye to the two intaglio printing rollers 34 and 35.
- Excessive dye is stripped ofi by means of a stripper, a so-called doctor blade, which is preferably made of brass sheet or of sheet metal and isresiliently arranged and variable as to its position and in particular with regard to the pressure at which it may be pressed against the rollers.
- the two doctor blades 42 and 43 are clearly shown in FIG. 4.
- the excessive dye is stripped off by the doctor blades from the rollers 34 and 35 and returns to the troughs 36 and 37.
- the mounting of the rouleau basket 33 in the tiltable frame 22 is effected in the tilted out condition of the tiltable frame 22. Basket 33 is inserted into the same bearing means which support the printing roller 10. In this way, among others, a mutual pressure influence will be avoided when the two intaglio copper printing rollers are subjected to pressure.
- the copper roller 35 is thus subjected to pressure by means of cylinder the machine only when the latter is employed for copper.
- Cylinder 45 is connected to the supporting pipe of the tiltable frame 22 by means of vice 46.
- FIG. 5 shows a section through the lifting off device operable by said hand wheels H1, H2.
- the said lifting off device comprises a spindle 51 having a head 52 acting upon a packet of cup springs 53. Further-more, a bolt 54 passes through spindle 51 at a point which is spaced from the head 52.
- Spindle 51 is provided with a flattened portion 55 the purpose of which consists in preventing a turning of the spindle 51.
- Bolt 54 is arranged at a point which is determined by the effort not to overload 17 and 4 respectively. This, however, has no influence upon the oppositely located rollers 20 and 6. This is due to the fact that the pressure at which the rollers 20 and 6 are pulled against rollers 17 and 4 depends on i the pressure prevailing in the two cylinders 57, 58 while the cylinders 57, 58 act upon lever arms 6a, 50a and Zita, 16a and turn the same about shafts '6', 50' and 20', 16'. It may be added that the drive of the multi-purpose processing device is effected by a motor II (FIG.

v 19 Claims. (Cl. 68-22) -The present invention relates to a device for process-- ing webs of textile fabric and other materials, according to which processing operations known per se are carried out in a single operation while the material passes through the device in a continuous manner.
Heretofore, the various operations for webs of textile fabric and other materials had to be carried out'on structurally different machines or devices such as Foulards or padding machines, jigs, full width wet treating devices, impregnating devices, driers, and thermosetting devices, or, if a processing by printing was involved, the operations had to be carried out on different printing machines. These heretofore known devices have the drawback that one phase only, i.e. one type of processing only, could be carried out on such machines. 7
Devices are known with which also different types of processing operations, in other words multi-phase operations, can be carried out during one passage of the respective material to be processed through the'machine. In such instances, however, pure aggregations are involved of known individual devices for carrying out one-phase operations. The mere structural arrangement side by side of such one-phase individualdevices to form a larger machine for carrying out multi-phase methods result in relatively huge devices.
the material and printing. These known devices, however, are not suitable for'carrying out a plurality of fundamentally different processes.
When carrying out processing or finishing operations in connection with webs of various types, especially of A further drawback of these known devices consists in that they are suitable for one definite multi-phase method only, for instance for priming 7 United States Patent the most complicated method combinations while requir textiles, yarn warps, fleeces of textile material and other A materials, papers, foils, 'films, plastic and other mate-,
rial, it is of particular advantage to carry out the operational phases in one operation and in as small a space as possible or to subdivide such processes which heretofore were'carried out in one stage only into two or more stages,
and to carry out such operations in a continuous working operation whereby the method will be greatly increased in efliciency. V
It is, therefore, an object of the present invention to provide a multi-purpose processing device of the general type mentioned above which will overcome the drawbacks outlined above. I g
It is another object ofthis invention to provide a multipurpose processing device of the typeset forth in the preceding paragraph which will be suitable for carrying out completely different processing operations which are independent of each other and can be carried out after minor simple adjustments have been effected.
It is also an object of this invention to provide a device as set forth above which will require a minimum of space.
These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings, in which:
FIG. 1 diagrammatically illustrates a cross section through a new processing device according to the present invention for processing textiles and other materials.
FIG. 2 illustrates a view of FIG. 1 as seen in the direction of the arrow A.

FIGS. 6 to 15 diagrammatically illustrate the working positions of the individual parts of the multi-purpose processing machine during the various processing operations carried out thereon. 7
FIG. 16 illustrates in form of a perspective view further details of the, arrangement according to the invention.
General arrangement While heretofore the machines for carrying out so-' called one-phase operations, such as dyeing, permeating, printing, impregnating, and also machines for carrying out two-phase operations, such as adhesive impregnating, lining of at least two webs of textiles or priming, printing and dyeing, have been known, the machine according to the present invention allows the combination of the above.
mentioned one-phase operations with the likewise above mentioned two-phase and multi phase operations. Thus, by means of the machine according to the invention it is possible for instance to pre-dye and subsequently during the same passage of the goods to print upon the goods, in order to mention merely one of the numerous examples of combination. Thus, the machine according to the present invention makes possible the simplest as well as ing merely minor and quickly effected adjustments of machine elements. In addition thereto, the machine according to the present invention also makes it possible to carry out completely new types of multi-phase operations which could not be realized on heretofore known machines, as for instance warp printing in combination with sizing, dyeing and printing and simultaneously therewith fixing ;the dye and the print.
The new multi-purpose machine for processing or fin;
ishing webs of textile fabrics, yarns, and other materials in which the materials to be processed pass between roll" ers engaging each other and having containers associated therewith for receiving processing material, is characterized in that the motor driven drive shaft has associated therewith Va tiltably journalled processing roller which is adapted to be subjected to various pressures, said processing roller being exchangeable for at least another processing device or printing roller. For purposes of carrying out multi-purpose processing operations, said drive shafthas associated therewith at'least one working group comprising a driven shaft and a squeeze roller carried along by the latter, and also a liquid container. The processing roller cooperating with the drive shaft is advantageously exchangeably'journalled on a tiltable lever which is adapted under a desired high pressure to. rest against the drive shaft. According to an advantageous embodiment of the multi-purpose processing machine, two working groups (groups of rollers) are provided in the machine together With the liquid containers associated therewith. The arrangement is such that one working group is located in the upper half of the machine whereas the other working group is located in the lower portion ranged symmetrically with regard to a central plane and when the rollers of each roller group are substantially identical to each other. In addition to the liquid containers mentioned above, advantageously the groups of rollers may also be preceded or followed by so-called spreader arms or rods in such a way that the webs of materials are fed to each roller group in a certain predetermined direction. Furthermore, each roller group is preceded by a special roller on which the material to be processed or a back gray cloth is wound up. Between one of these rollers or docks and a group of rollers, there is provided in conformity with a further feature of the present invention, a dust removing device which may be provided with a brush known per se and a suction device, the effect of which may be improved by an electrifying apparatus. This dust removing device has the purpose, prior to the first processing operation, to remove any impurifications such as fibers or the like from the web to be processed. In addition to the so-called liquid containers, laterally sealed squeezing gaps are provided between said individual rollers where likewise a humidifying, wetting, coating, or other chemical treatment of the goods maybe effected.
A further important feature of the multi-purpose processing machine according to the invention consists in the small space required by said machine. This advantageous feature is obtained primarily by journalling each of the rollers on a shift lever, while two shift levers in the same direction are actuated by a power accumulator only such as a pressure cylinder. In order to adapt the pressing pressure of the power-interlocked rollers, the pressing rollers located in front when considering the direction of movement of the material, have associated therewith a preferably manually operable adjusting device.
The processing roller associated with the drive shaft may, depending on the particular processing operation to be carried out, have associated therewith a simple squeezing roller, a heated calender, a multi-dye roller with solid dye. Furthermore, the processing roller journalled on the tiltable lever operable by a power cylinder may be exchanged for a rouleau or roller printing basket in which for instance two rouleau printing cylinders are mounted with chassis and doctor blade as well as a pattern register adjusting device. The lower printing roller of the two printing rollers journalled in the rouleau printing basket has associated therewith a separate accumulator which presses these pressing or printing rollers against the drive shaft proper of the machine.
According to a further important feature of the invention, a motor driven trueing or dressing device is mounted on that tiltable lever arm in which the various processing rollers may be journalled in exchangeable manner. This trueing or dressing device has associated therewith a drive motor which latter after tilting out the processing roller with tilting shaft, will drive on one hand the support of the trueing device and on the other hand the color roller or printing roller to be dressed. The dressing device permits a dressing or trueing of the color roller in order to eliminate unevenness which might form due to uneven wear of the individual dye layers of the roller during the printing operation.
The multi-purpose processing device according to the present invention may be operated in different manners by simple adjustment of individual parts thereof. As has been mentioned above, one-phase processing operations, such as dyeing, permeating, printing, impregnating and the like, may be carried out by said multi-purpose processing machine. Furthermore, webs of goods may be coated unilaterally or may be glued together to another web ,of goods.
By means of the machine according to the present invention, when providing a roller printing basket on the shift lever carrying the processing rollers, deep printing or photogravure or copper plate printing may be carried out. If the webs of goods to be printed upon are subjected prior thereto to a dyeing operation, for instance a pigment dyeing operation, the carrying out of multi-phase processing operations such as pigment dyeing, can be effected with subsequent roller print. In addition thereto, at least two webs of material may be laminated toether. When webs of material are to be provided with multi-color print, the webs of material may prior thereto be impregnated or treated chemically. For instance a web of goods may first be provided in a chassis with a primer and subsequently may be printed upon in multicolor print. It is also possible that one and the same web of goods will during a single passage through the machine successively be subjected to different one-phase operations. For instance, a web of goods to be processed may first be moistened, then be impregnated in a different phase, and subsequently be provided with multi-color print. bined operations on one and the same machine during one and the same passage of the goods to be processed cannot be carried out on any of the heretofore known devices of the type involved. The processing operations which will be set forth below are merely examples of an almost infinite number of other possibilities of application of the machine. These possibilities from the simplest one-phase operation to the most complicated combined operation may be varied merely by a slight adjustment in the machine.
Structural arrangement Referring now to the drawings in detail and FIG. 1 thereof in particular, this figure shows a multi-purpose processing machine designed as multi-color-printing machine of the so-called Devina printing machine type. As will be seen from FIG. I, mounted on the left-hand side of the machine (with regard to FIG. 1) are two rollers W1, W2 having wound thereon the fabric material which is to be fed through the machine. The lower roller W1 contains the fabric material St to be processed, whereas the upper roller W2 has wound thereon the back cloth M. Between the two rollers W1 and W2 there is arranged a device E for withdrawing dust from the goods. When looking in the direction of movement of the goods, the material to be processed, for instance the material St to be printed upon, passes through the dust withdrawal device E via a roller or bar 2 to the lower three-roller-Foulard A1. The intermediate roller 4 of the three rollers 50, 4, 6 is driven. The goods are passed between the left-hand roller 50 and the intermediate roller 4 and then move through a liquid container or trough 3. In the said liquid container 3 the goods St are wetted by a liquid which may consist of pure water or a chemical. The goods are passed over a deviating roller 3a in the liquid container 3 and then pass over a spreader or roller 5. Finally, the goods are squeezed between the right-hand roller 6 and the intermediate roller 4. 'Aftr leaving the squeezer rollers, th goods pass over a spreader or roller 7 and a deviating roller 8 to the driving roller or cylinder 9, the so-called press cylinder and then around the dye cylinder 10.
In order to obtain a suificient contact of the webs of the goods St to be processed with the dye roller 10, the roller 10 has associated therewith two further pressing rollers 11 and 12 for purposes of increasing the looping angle, each of said rollers 11 and 12 being individually pressed against roller 10 by separate pressing means, such as the pressing cylinders 31, 32 and levers 11a, 12a. After the goods have passed over the dye roller 10, which may also be called printing roller, the goods are approximately vertically conveyed in upward direction and are then passed through a drier not shown in the drawings.
The upper roller W2, as mentioned above, carries a follower material M which is passed over a roller or bar 15 and from there moves between the squeezer rollers 16 and17 into a trough 18. From here the material M is passed over roller 19, between squeezer rollers 17 and 20 and over roller 21 to the press cylinder 9. The follower material M passes around the rollers 9 and 10 in the same manner as the goods St, however on the'back side thereof This possibility of carrying out so-called com-' sothat the follower material is printed upon only on the.
edges protruding beyond the goods St. The follower material M also takes care that the dye protruding beyond the printing Width on printingroller will be worn up to the same extent as that on the intermediate roller portion which prints upon the goods St. Thefollower material M then likewise moves upwardly and, more specifically, is deviated toward the left from printing roller 10 below the drier because the follower material does not have to be dried. After about 300 yards of the goods have been printed upon, the dye roller is worn olf irregularly because, not all dye concentrations are uniformly conveyed to the goods. In order to equalize the uneven Wear of the dye roller after a certain time of operation, the shift lever 22' has mounted thereon a trueing device B which includes two supporting bars B1, B2 and a draw spindle Z which moves the support or carriageSu mounted on the supporting bars B1, B2 toward the left and toward the right. Said support or carriage Su is shown in FIG. 2 and is driven by a motor I drivingly connected to two shafts Ia, lb. Shaft Ia at the left side of motor I drives the draw spindle or feed spindle Z of the carriage Su of the honing device .13. The feed spindle Z is automatically turned off when the carriage Su has reached its end position and has to be turned on anew while the direction of rotation has to be reversed. Shaft Ib on the right-hand side of motor I drives the printing roller 10 when the latter is tilted outwardly (see FIG. 3) and is to be trued.
FIG. 3 shows a cross section through the machine with the tilting frame 22 in tilted-out position. This tilting is' effected by means of a power cylinder, preferablya compressed air cylinder 23. When frame 22 is tilted inwardly, also motor I and trueing device B are tilted. In the outermost tilted out position, motor I mounted on the' tilted frame 22 is turned on through the intervention of switch SH shown inFIG. 2. Motor I is a threeephase. pole reversible motor and thus is adapted to rotate at obtained. By means of the knurled hand wheel 24 knife" 25 may be moved against the printing roller 19. After the tiltable frame 22 has been tilted through the intervention of a pneumatic cylinder 23, a preferably hydraulically effective brake 23' is required which is actuated in steps. In other words, when the piston of said hydraulic brake cylinder 23' passe-s by certain bores in the wall of said cylinder, the oil stream passing from the front to the back of the piston is decreased or increased as to its cross section.
Inasmuch as when tilting out the tiltable lever 22, the pressure rollers 11 and 12 must be tilted away from the printing roller 10, the tiltable frame 26 is turnable about pivot point 27 as will be evident from FIG. 1. The tilting away of rollers 12 and 11 with lever 12a, 11a is effected in conformity with FIG. 3 by means of a power operable piston, for instance a pneumatically operable cylinder 28 which is indicated by dash lines in FIG. 3. Piston rod 29 of cylinder 28 is connected to one end of a lever 30 the other end of which is pivotally connected to the tiltable frame 26. When moving piston rod 29 outwardly, lever 30 is turned about shaft 27 and thus moves away parts 12, 12a, 11, 11a with cylinders 31, 32 by means of lever 26 connected to lever 30. The upper roller 11 and lower roller 12'are pressed against the printing roller 10 by means of two preferably likewise pneumatically effective pressure cylinders 31 and 32, cylinder 31 acting upon the upper pressure roller 11 and cylinder 32 acting upon the lower pressure roller 12. Therefore, when tiltable frame 22 is to be tilted outwardly for tr-ueing or changing roller 10, frame 26 has to be lifted. To this end, first the two pressure rollers 11 and 12 are lifted off the printing roller 10. As soon as this has been done, the cylinder 28 is subjected to compressed air so that the entire tiltable frame 26 tilts upwardly by an angle of approximately 90. When 6 the tiltable frame 26 is in its upper tilted out position shown in FIG. 3, the two rollers are tilted into their stretched position so that the goods St move upwardly and the follower material M can not be displaced from its substantially vertical withdrawing direction.
The motor employed for driving the trueing' device B and for simultaneously driving the dye roller 10 to be trued has a still a further task. This additional task consists in driving the dye mechanism ofthe rouleauprinting basket 33. The basket 33 according to FIG. 4.
has mounted thereon two copper intaglio printing rollers 34 and 35. These two rollers 34 and 35 have to be fed with dye. To this end, two dye feeding means are provided which pick up the dye from troughs 36 and 37 and respectively convey the dye uniformly through brushes 38 and 35 to a distributing roller 40 and 41 respectively which in their turn convey the dye to the two intaglio printing rollers 34 and 35. Excessive dye is stripped ofi by means of a stripper, a so-called doctor blade, which is preferably made of brass sheet or of sheet metal and isresiliently arranged and variable as to its position and in particular with regard to the pressure at which it may be pressed against the rollers. The two doctor blades 42 and 43 are clearly shown in FIG. 4. The excessive dye is stripped off by the doctor blades from the rollers 34 and 35 and returns to the troughs 36 and 37. The mounting of the rouleau basket 33 in the tiltable frame 22 is effected in the tilted out condition of the tiltable frame 22. Basket 33 is inserted into the same bearing means which support the printing roller 10. In this way, among others, a mutual pressure influence will be avoided when the two intaglio copper printing rollers are subjected to pressure. The copper roller 35 is thus subjected to pressure by means of cylinder the machine only when the latter is employed for copper.
intaglio printing. When other working operations are to be carried out, cylinder 45 it to be removed. Cylinder 45 is connected to the supporting pipe of the tiltable frame 22 by means of vice 46.
Referring back to FIG. 1, two hand wheels H1 and H2 are I shown in side view on the left-hand side of the two rollers W1 and W2. hand Wheels H1 and H2. consists in lifting off the rollers and 15 fro-m the driven Foulard rollers 4 and 17 or to reduce the pressure exerted thereupon. FIG. 5 shows a section through the lifting off device operable by said hand wheels H1, H2. The said lifting off device comprises a spindle 51 having a head 52 acting upon a packet of cup springs 53. Further-more, a bolt 54 passes through spindle 51 at a point which is spaced from the head 52. Spindle 51 is provided with a flattened portion 55 the purpose of which consists in preventing a turning of the spindle 51. Bolt 54 is arranged at a point which is determined by the effort not to overload 17 and 4 respectively. This, however, has no influence upon the oppositely located rollers 20 and 6. This is due to the fact that the pressure at which the rollers 20 and 6 are pulled against rollers 17 and 4 depends on i the pressure prevailing in the two cylinders 57, 58 while the cylinders 57, 58 act upon lever arms 6a, 50a and Zita, 16a and turn the same about shafts '6', 50' and 20', 16'. It may be added that the drive of the multi-purpose processing device is effected by a motor II (FIG.
2) which through a V-belt or the like acts upon a transmission III which in its turn through the intervention a quickly disengageable clamping de-.
The purpose of these two.
of separate chain drives or the like conveys driving power to shaft 9a of drive shaft 9 and to shaft 4a of that roller of the working group A2 which corresponds to the driven Foulard roller 4 of the working group A1 and 17a. 7 FIGS. 6 to 14 diagrammatically show a number of possible applications of the machine according to the invention.
FIG. 6 shows the simplest method, namely the squeezing of wet goods or the withdrawal of Water therefrom. The wet goods are passed from the roller W1 over a roller 2 between the squeezer rollers 4 and 5t and after being squeezed pass around roller 4 between rollers 4 and 6 for further squeezing and from there over a deviating roller 66 into a drier T. The deviating roller 60 is arranged above the material directly in front of the inlet into the drier T.
FIG. 7 shows a method according to which the goods St are unilaterally coated. The goods St pass from the roller W1 over a roller 7', the roller 8 to pressing cylinder 9 and are by means of roller 35 unilaterally coated. The coat, for instance a dye or a cement or a synthetic material, is stored in trough 37 and is conveyed to roller 35 by means of a distributing roller 39. In order to prevent the pressing cylinder 9 from being soiled laterally by the respective impregnating layer, it is advisable to pass a follower material M from roller W2 over deviating roller 64 and roller 21 to the pressing cylinder 9. After the coating has been effeotcd,.the follower material M is passed away from the goods St and over a deviating roller 65 below the drier T toward the left where it is again wound up. The goods St are conveyed over roller 65 to the dried T.
FIG. 8 diagrammatically illustrates how the copper intaglio printing method may be carried out on the machine according to the invention. The goods are passed from the roller W1 over roller 7 to roller 8 and from there to the pressing cylinder 9. Below the goods there is again a follower material M which is withdrawn from roller W2 via deviating roller 64 and roller 21 and passes to the pressing cylinder 9. The webs are printed upon in conformity with the description of FIG. 4 by copper intaglio printing rollers 34 and 35 which are fed by dye . applicators 38 and 39 with dye from the troughs or reservoirs 36, 37. The goods leave the machine in upward direction and are deviated by rollers 65 and 65'. The printed goods St pass through the drier T whereas the follower material is passed toward the left below the drier.
FIG. 9 shows the pigment coloring by rouleau printing. To this end, the goods St are passed from roller W1 via roller 2 to the squeezer bite 67 where they are chemically pre-treated and passed through the two rollers 50 and 4 into the trough 3 where the goods are pigment dyed. The thus dyed goods are passed via roller 5 between the two rollers 4 and 6 and over roller 3 to the printing cylinder 9 where the goods are printed upon by the two copper intaglio printing rollers 34 and 35. Also in this instance, the follower material M passes below the goods after being withdrawn from roller W2 and guided over the deviating roller 64 and roller 21 and between goods St and drive roller. After the printing has been effected, the follower material M is passed upwardly by means of rollers 34 and 35 over deviating roller 65 and conveyed toward the left whereas the goods move over the deviating roller 65' into the drier T.
The arrangement is also suitable for unilateral pigment dyeing, if a doctor blade is mounted above roller 6, and the goods St are guided accordingly.
FIG. illustrate the laminating of two webs of goods. The webs of goods St are passed from roller W1 over the deviating roller 66 to roller 5 into the bite between rollers 4 and 6 and then over the deviating roller 7 and roller 8 to the roller 9. The webs of goods St are withdrawn from roller W2 and passed over the deviating roller 64 to roller 21 and then likewise to the roller 9.
The binder, for instance rubber, employed for lining is located in the bite 67. By means of the relief device according to FIG. 5, roller 54) is withdrawn from roller 4 to a certain extent. This extent determines the thickness of the rubber coating. Roller 4 driven by a motor now draws a rubber layer into the bite between the rollers 4 and 6 and coats the upper side of the goods St. This upuper side will during the movement around the pressing cylinder 9 contact the goods S2. For making the intermediate layer permanent, a roller 63 is provided which is mounted on the tiltable frame 22 and may be heated. The two webs of goods St and St are connected to each other by pressure and the temperature between the rollers 9, 68, and via the deviating roller 65' leave the machine. If it should be necessary, they may be passed through drier T for hardening the binder.
Above roller 6 there may be provided a doctor blade (not shown in the drawings). Such doctor blade will be indispensable when the laminating or lining mass is being deposited on one side only, namely the inner side of the web St. In such an instance, the outer sides of the two webs St and St remain without laminating or coating mass.
FIG. 11 shows the lining of three webs of goods. The webs of goods St pass from roller W1 via rollers 7 and 8 to the pressing cylinder 9. The webs of goods St pass from roller W2 to roller and from there between rollers 16 and 17, through trough 18 and from there over roller 19, roller 20, deviating roller 64' and roller 21 likewise to the pressing cylinder 9. The web of goods St will be coated on both sides during the passage thereof through trough 18. The trough 18 contains the coating material in liquid form. The web of goods St" passes from roller W3 over deviating roller 64 to roller 21 and from there directly to the pressing cylinder 9. By pressing against the heated calender 68 which may be pressed against the pressing cylinder 9 by means of the tiltable frame 22, the said three webs of goods are connected to each other and while moving vertically upwardly pass over the deviating roller 65' and are conveyed through the drier T which, if necessary, will harden the binder.
FIG. 12 illustrates the multi-color printing according to the so-called Devina method. The goods are withdrawn from roller W1 and passed over the dust withdrawing device E, roller 2, then between rollers 4 and into the trough 3 and from there over roller 5 between rollers 4 and 6, over deviating roller 7 and roller 8 to the pressing cylinder 9 where the goods are printed upon by the printing roller 10. The goods are looped around the printing roller 10 and are pressed thereagainst by an upper roller 11 and a lower roller 12. The goods then leave the machine via deviating roller and are dried in the drier T. In order to prevent soiling of the pressing cylinder 9, a follower material or back cloth is passed between pressing cylinder 9 and the goods to be printed upon. This back cloth is withdrawn from roller W2 and passed over. roller 15, between rollers 17 and 16 into the trough 18 and over roller 19 and then squeezed between rollers 17 and 2t). The trough 18 contains wetting liquid. The back cloth M is introduced between the pressing cylinder 9 and the goods St to be printed upon. The designation Devina relates to the printing method by means of a mosaic roller 10 on which the dyes are deposited in form of consistent masses.
If a simultaneous priming or bottom dyeing of the goods St to be printed upon is desired, the method according to the present invention will be carried out in conformity with FIG. 13. As will be evident from FIG. 13, the goods are withdrawn from roller W1, passed over dust withdrawing means E, roller 2 and are further passed between rollers 50 and 4.. The squeezing gap or bite is filled with wetting liquid while known lateral seals fitted to the rollers at the end of the gap will assure that the wetting liquid will not flow oif laterally from the rollers 54 4. After the goods St have passed the squeezing gaps 67 they pass through trough 3 where they are dyed and then pass over roller 5 and between the rollers 4 and 6 and leave the working group A1,-while the goods St are stripped of excessive dye. The goods then pass via deviating roller 7 to roller 8 and to the pressing cylinder 9; the path of the back cloth M corresponds to that of FIG. 12. Also in this instance, a multi-color roller It) coated with dye material rests against the pressing cylinder 9, said multi-color roller being pressed against the pressing cylinder 9 by upper and lower rollers 11 and 12. After the goods have been printed upon, they leave the machine via roller 65' and move into the drier T whereas the back cloth leaves the machine via roller 65.
It is, of course, .to be understood that a dyeing may also be effected with the bite of rollers 4 and 6 of FIG. 12. In this instance, a doctor blade is to be arranged above roller 6, and the web is to be guided accordingly. It is also possible by means of the doctor blade unilaterally on that side of the web which is not to be printed upon, to deposit a mass such as which will prevent the Davina print from passing through the web, thereby keeping the non-printed-upon side of the web clean and without designs.
' FIG. 14 illustrates a method according to which the webs of the goods St are not only processed in the working group All 'but also additionally in the working group A2. The goods St are in addition to being subjected to a wetting operation also subjected to a dyeing operation. If two further treatments of the goods are required, the goods are passed over the dust withdrawing device E, the deviating roller 2', roller 2 and then passed to the. squeezing gap 67 in front of the rollers 16, 17 which squeezing gap 67 is filled with wetting liquid. This wetting liquid simultaneously serves for wetting the follower material M withdrawn from roller W2. The goods leave the squeezing gap between rollers 16 and 17 and move vertically downwardly via roller 2 into the squeezing gap 67 between the rollers 50 and 4. In this squeezing gap 67, the goods are subjected to a further chemical treatment, such as a dyeing operation. This chemical treatment may also be an impregnating operation or any other chemical operation as they are customary nowadays with synthetic materials. After the goods have left the squeezing gap between rollers 59 and 4, the goods enter the trough 3 where they are treateda third time. The
goods are passed via holders or rollers 5, 6, 7, 8 to the pressing cylinder 9 and to the printing roller pressed thereagainst. Pressure rollers 11, 12 press against the printing roller 10. After the goods have been subjected to the multi-color printing operation, they are withdrawn in customary manner, whereas the follower material M, the purpose ofwhich consists in protecting the pressure cylinder 9 against soiling, will in a manner known per so be passed over the deviating roller 65 below the drier.
FIG. illustrates a further processing, namely a twophase dyeing method,such as the naphthol dyeing. With this dyeing method, the goods withdrawn fromrollerWl will be primed or impregnated in the working group A2 and will be naphtholated in working group A1; In order to be able to increase the speed of passage of the goods also when heavy goods are involved and in order to assure a uniform dying effect, the priming operation is carried out twice in the working group A2, namely in the laterally sealed squeezing gap 67' and also in trough 1%.
The squeezing in squeezing gap 67 immediately following the priming will assure a good venting of the goods. After squeezing the goods once more between the .rollers'17 and 18, the goods are passed .over the deviating roller and the roller 2 into the squeezing gaps 67 where the goods are naphtholated or coupled for the first time. Following the squeezing operation between rollers 50 and 4, thegoods are naphtholated a second time in trough 3 and are subsequently squeezed again between rollers 4 and 6. The goods are then passed over the rollers 7, 8 and 65' into the drier T. Advantageously, the rollers 11 and 12 are coated with an elastic material, for in stance elastic-rubber or Mipolan.
In the drawing, the webs of goods are indicated by dot-dash lines, whereas the follower material which is not printed upon and is employed merely for protecting the pressure cylinder, is indicated by two dot-dash lines.
In order to permit the changing ofthe machine from one phase to another operational phase and to simplify such change, the lateral walls of the machine are provided with bores for mounting the various rollers and deviating rollers which according to the invention may be mounted in different positions so that the respective rollers can without dimculty be moved to their predetermined position.
With regard to the arrangement shown in FIG. 16, it will be noted that the spindle Z has mounted thereon a nut 66 fixedly connected to the support Su. Rotation of spindle Z in clockwise direction causes the nut 66 to move in the direction of the arrow 67, whereas rotation of spindle Z in counter-clockwise direction will cause nut 66 to move in the direction of the arrow 68'.
The alternate rotative movement is produced by a control transmission through the intervention of two oppositely toothed ratchet wheels 69 and 70. Mounted on shaft Ia is a crank.71 which, by means of a connecting rod 72 is adapted to allow a tiltable yoke 74to ,oscil-, late about a shaft 73. The ends of the two yoke halves 75, 76 have mounted thereon two rollers 77, 78 which resiliently rest against the two pawls 79, 80. The resiliency is made possible by a torsion spring 81 built into shaft 73. a i When occupying its ordinary position, shaft 73 is held in its intermediate position by a torsion spring 82 which is likewise built into shaft 73. In this way, pawl 79 cannot engage the ratchet 69, nor can pawl $0 engage the ratchet wheel 70. If, by means of lever 83, shaft 73 is tilted in the direction indicated by the arrow 34, the yoke 74- and roller 77 will bring pawl 79 into engagement with ratchet wheel 69. The spindle Z will then movein clockwise direction, while nut 66 will move in the direction of the arrow 67. In order to bring about said engagement, lever 86 is displaced axially, after said tilting movement, in the direction of the arrow $5 so that it will also displace shaft 73 axially. Lever 86 at this time engages key 87 by the groove 88 in the hub of the lever which will hold the lever in its tilted position.
In this position, nut 66 will move in the direction of the arrow 67 until support Su abuts the hub of lever 83, and moves the same toward the left in the direction of the arrow 89 until the key 87 leaves groove 88 and the torsion spring 82 returns shaft 73 to its intermediate position. As mentioned in the intermediate position of shaft 73, neither of the pawls 79, 8t) engages the respective ratchet 69, 70. Spindle Z will now be at a standstill and consequently, also support Su.
If the opposite movement a nut 66 is to be initiated, lever 83 or lever 86, depending on whether the operator is located toward the right end or toward the left end of the machine, will be tilted'in the direction of arrow 99 whereby roller 73 presses against the pawl to cause pawl 80 to engage ratchet 70, and whereupon spindle Z will begin to rotate in counter-clockwise direction. 1
, In view of this rotation, nut 66 moves in the direction of the arrow 68. In order to lock shaft 73 in the last mentioned position, key 91 is mounted on the left-hand side of the machine and which key engages a groove 92 in the hub of lever 83. To efifect this engagement, shaft 73 is displaced axially in the direction of the arrow 89 toward the left with regard to the drawing. When support Su reaches its right-hand end position, it abuts the hub of lever 86 and displaces the shaft in the direction of the arrow until the key 91 has left groove -92. Due to the torsion spring 82, shaft 73 will be tilted to its center position so that the support will again come to astop.
It is, of course, to be understood that the present .in-
ii a
