Definitions
- the invention relates to apparatus for semi- Wet development of photoprints, adapted to apply a thin film of the developing liquid to the material to be developed, said apparatus being provided with a rotary liquid-applying-roller, having in its circumferential surface a plurality of channels or grooves extending transversely to the axis of the roller and further of the type in which a rotary liquid-transmitting-roller is interposed in the path of the liquid supply to the grooved applying roller.
- Apparatus of the kind referred to is well known from U. S. Patent 2,241,104 (to compare page 4, right column, lines 39-55) where the transmitting-roller has been called an auxiliary roller. If certain requirements described in this patent, are satised, apparatus of the kind referred to applies an even liquid layer of definite thickness (e. g. 8 cubic centimeters, viz. 8 grammes when the specic gravity of the liquid is l, per sq. metre) to the material to be developed. The thickness oi the layer (expressed in the number of grammes per sq. metre) which the apparatus supplies to the photoprint material, however, is dependent on the speed with which it is operating (compare e. g. U. S.
- definite thickness e. g. 8 cubic centimeters, viz. 8 grammes when the specic gravity of the liquid is l, per sq. metre
- Patent 2,241,104 page 4, left column, lines 66-69).
- the apparatus For a required thickness of the liquid layer, i. e. for a required application, determined by the requirements of the necessary development, the apparatus has to be operated at a fixed speed i. e. its speed has to be controlled.
- the object of the invention is to make the application of liquid less dependent on the operating speed, meanwhile however maintaining an application roller having grooves or cross channels for the sake of its inherent advantages. These advantages are that such channeled rollers only cause a small stained edge at the end edge of the sheets to be developed and only little starter (under development) at their starting edge. (For this starter compare U. S. Patent 2,241,104, page 2, left column, line 33).
- the capillary liquid applying roller in a developing machine of the kind referred to the capillary liquid applying roller is operated in contact with a liquid transmitting or auxiliary roller which replenishes the channels of the applying roller, and the transmitting roller is caused to cooperate with a raking or doctor- 2 device which limits the quantity of liquidtransmitted via its surface.
- the developing machine according to the invention is not in all its parts equipped for socalled "parallel run i. e. that the surface o1' the material under treatment and that of the roller cooperating with it are moving in the same direction.
- the material to be developed Will be made to run with a speed equal or almost equal to that of the grooved roller.
- stationary doctoring parts which may cause troubles, preferably will be avoided. Diioulties e. g. may occur owing to the formation of crystal crusts from the developer, to iilthiness of the developer and of the material to be developed, to particles detached from the crusts etc. Consequently the doctor-device is preferably of the kind comprising at least one rotating roller.
- FIGS 1-5 are diagrammatic sectional elevations of various embodiments of the liquidapplication-section of developing'apparatus.
- Fig. 6 is a partial longitudinal section of a cross grooved roller.
- Fig. '7 shows part of a doctor-blade or doctor'- knife.
- Fig. 8 is a partial elevation of a roller adapted to be used as an auxiliaryor doctoring-roller.
- v Fig. 9 represents part of the surface of another embodiment of such an auxiliaryor doctoring-roller.
- I represents a roller of a diameter of millimetres consisting of a metal core 2 coated with 21/2 mm. of a suitable synthetic material 3, which contains helically wound cross grooves 6 (see Fig. 6).
- the helix has a pitch of 0.5 mm.
- the grooves have a Width of 0.15 mm. and a depth of 0.8 mm. So this cross grooved roller has a passage" of 2v00 0.8 0.15 :24 mm2 per decimeter of axial roller length.
- Fig. 5 there are two applying-rollers I and -I with cross grooves. This equipment is used for two-sided development. S represents in Figs. 1-5 the material to be developed, which passes in the direction of the arrow over the grooved roller(s).
- 'I and 'I' are auxiliary-transmission rollers cooperating with the cross grooved roller I and I' respectively.
- 'I'he guttershaped reservoirs 9 and 9 contain the developer liquid I0 and I0'.
- the auxiliary "I in Figs. 1 to 4 function in essentially the same way, except that .in Fig. 3 roller 'I does not dip into the reservoir.
- the various rollers rotate in the directions indicated by the arrows.
- the transmission roller 'I by its rotation carries the liquid I0 upwards.
- the doctor blade I3, illustrated in Fig. 'I has recesses I4 at distances of 4 mm. that are 0.1 mm. deep and 0.3 mm. wide.
- Roller 'I has a smooth surface.
- the quantity of liquid that passes through and is limited by this passage and which is carried to the cross grooved roller I is such that roller I at speeds of cm. to 6 metres per min. applies about 8 grammes viz. 8 cubic centimetres per sq. metre to the material S that is to be developed.
- roller 'I can also be provided with helically wound canals I5 on its surface, as represented by Fig. 8.
- helix of these canals has a pitch of 4. mm.
- the canals I5 have a cross section of 0.1 x 0.3 nini. and when the doctor blade I3 is without recesses, consequently with a straight sliding edge, the result obtained will be quite analogous to that of a smooth roller 'I' combined with a doctor blade according to Fis. 7.
- Fig. 2 illustrates an arrangement that is identical in principle to that of Fig. 1.
- roller 'I has been substituted by a doctoring-roller I6. chosen for this doctoring roller it will be possible to equip roller 'I with canals as described and as represented by Fig. 8. If on the contrary roller 'i has a smooth surface, roller IS is to be equipped with appropriate canals. t is also possible to equip the rollers 'I or IG with pits lI as represented in Fig. 9, which pits have been evenly distributed over the surface of the roller, in such a manner that the contents (the total volume) of the pits is approximately the same as the contents (the total volume) of the canals described for roller I.
- roller I and roller I5 both with canals or pits; the limitation of the liquid then is determined by the sum of both the passages
- this system of liquid limitation can also be applied to the apparatus according to Fig. 1 and also to those according to the Figures 3 to 5.
- the limiting passages cause the cross grooved roller I to produce an application of about 8 grammes per sq. metre at various speeds. If desired this passage and consequently the liquid application can be decreased or (which, however, as a rule is undesirable) increased.
- the doctoring roller I 6 also acts as a supplying roller for the transmission or auxiliary roller 'I. It is mounted on the right-hand side of roller 'I, i. e.
- rollers I and I5 both act as supplying rollers.
- the upper part of the roller I, above the line of Contact with roller IG provides for the transmission of liquid to the appli-- cation roller I.
- rollers l and I in r'g. 5 are the cross grooved rollers that apply liquid to both sides of the material S to be developed.
- Cross grooved roller I cooperates with transmission roller ⁇ I; cross grooved roller I with transmission roller 'I'.
- the roller 22 doctors off roller 1 and roller 22 doctors off roller 'I'.
- the applying rollers I and I can also be supplied with liquid via a series of rollers instead of one roller (a series of rollers arranged one behind the other and contacting each other in succession).
- developing apparatus are particularly adapted for use in combination with an exposure apparatus for continuous exposure of photoprinting material e. g. diazotype paper.
- printing is preferably done on a long uninterrupted If a smooth surface is' band of light-sensitive paper, which passes through the exposure apparatus e. g. over a glass cylinder surrounding a tubular lamp, the tracings to be copied being carried along between the glass cylinder and the band of light-sensitive paper.
- the transparency of the tracings varies in practice and in order to obtain the right exposures the exposing cylinder is made tok run quickly in case of a more transparent tracing and slowly in case of a less transparent one. So the band cf material to be developed that leaves the exposure apparatus will have a speed that is variable Within rather wide limits.
- this band will nevertheless be required to pass as a Whole continuously through the developing machine immediately after the tracings have been exposed and removed.
- the developing machine according to the invention is extremely suitable for that purpose, and its driving mechanism is advantageously adapted to move with more than one speed, while in the combination with a continuously operating exposure apparatus the driving devices advantageously can be chosen in such manner that the developingand the exposure-sections are operated at speeds adapted to one another, the speed of the combination being variable.
- the speed variation can amount from a certain minimum speed to a fold speed.
- the developing section according to the invention is advantageously given a speed. of some per-cents greater than that of the exposure section. Owing to this procedure some slip arises in the contact zone between the material S to be developed and the developing roller I and it is notoriously an advantage of the developing machine according to the invention that no drawback is experienced from such difference in speed.
- the various rollers in the machine according to the invention can be made of any suitable material.
- the only general requirement for the material to be used is that it has to be non corrosive. So preferably iron or brass is avoided but e. g. stainless steel, rubber, synthetic materials glass etc. are recommended.
