PROCESS FOR THE PRODUCTION OF ROLL GOLD STAMPING FOILS UPON-PLATES OR BANDS Filed Jul 24, 1950 remind Sept'25, 1934 PATENT oFFic E PROCESS FOR THE PRODUCTION OF ROL L- GOLD STAMPING FOILS UPON PLATES OR BANDS Karl Wirth, Berlin-Charlottenburg, Germany,
assignmto Julius A. 0. Flchtmueller, Stapleton, Staten Island, N. Y.
Application In July 24, 1930, Serial No.470,254 Germany April 2, 1930 2 Claims. (01. 204-8) Roll-gold stamping foils haveso far been so produced in a commercial form, that known qualities, in most cases orange or lemon coloured beattinuous paper of limited width in accordance with 1 known methods in conjunction with an adhesive substance or gluten having a low melting point.
This process is extremely troublesome, requires highly skilled workers, specially trained to the work, and is about 50% more expensive than the beaten, unmounted lea! gold of the same size. It has been attempted, instead of employing beaten leaf gold, to produce the so-called party-gold with the aid of electrolytically produced gold deposits in conjunction with other'metals, e. g. silver and the like, in accordance with known methods, and to transfer these metallic layers or the gold only, also by means of adhesive sub stances or glutens, to suitable paper or other mounts or carriers ready to receive the foil, for instance, pergamyn paper, cellophane etc. All such endeavours, however, have not produced the desired result, owing to the fact, that the removalof the electrolytically produced layer or layers, without leaving a trace, with the .aid or abovementioned expedients requires the employment of an adhesive substance or gluten of considerable adhesiveness, which, however, was the cause, that during the stamping operations proper the metallic layers did not allow 0! being transferred to the object to be stamped, because they adhered too i strongly to the auxiliary layer or carrier, whereas in conjunction with the employment of adhesive substances or glutens with lesseradhesive properties .the removal of the electrolytically produced layer without leaving a trace is impossible.
The process in accordance with this invention is based upon the idea of employing a slow combustible carrier, which renders it possible, with the aid of little or no adhesive substance or gluten at all, to remove, without leaving a trace, electrolytically produced metallic layers and which, when stamping with a hot die, loses its own adhesiveness, thereby releasing, without leaving a trace, the metallic layers in form of the stamping die, which with the bucket the gold foil or layer being correspondingly grounded, securely adhere to the object being stamped. The carrier in accordance with this invention serves, on the one hand, as transfer medium of the metallic layer from the mount and on the other hand, as carrier of the removed metallic layer and simul- .lytically deposited, upon which the liquid carrier metal stamping foil which consists in depositing taneously as delivering agent of the metallic layer to the object to be stamped. I
In consideration of the fact that by emplo a liquid carrier considerable surface tensions are caused, rendering it possible to remove the metallic deposits without leaving a trace, e. g. as known by employing liquid gelatine, it was ascertained, that electrolytically produced deposits upon metal plates or hands for the production of roll-gold B5 stamping toils, may be removed without leaving a trace through the medium of a liquid carrier, produced irom a cellulose esterwith a certain degree of acetylation which is a well known commercial product and varied by means of softening or hardening media. This renders it possible to undertake stamping operations upon a big scale, resulting in a saving of work and material. A further saving of gold is effected owing to the iact that the gold, which does not adhere to the object to be stamped, remains upon the carrier. The waste-gold, resulting from the stamping operations, may be entirely recovered, and the carrier proper, by being reduced 'to a liquid state, may also be employed again. r
In the drawing the process has been represented by way of example on aconsiderably emlarged scale. Upon a bandor leaf-like base a one or more metallic layers 12 have been electro- 0, consisting of acetylated ester, is applied. After the carrier has solidified, the layer 12, together with the layer c may be removed andconstitutes a roll-gold-stamping toil which, after being correspondingly grounded in a known manner, may be employed for stamping purposes without any further preparation.
I claim: I
1. The process for the production of rolled metal upon a support, covering the metal with an acetylated cellulose ester in liquid form, allowing it to solidify and mechanically separating the solidified sheet and deposited metal together from said support.
2. The process for the production of rolled metal stamping toil which consists in electrodepositing the metal upon a metal support, covering the deposited metal with an acetylated' cel-' lulose ester in liquid form, allowing it to solidify and mechanically separating thesolidified sheet and deposited metal together from said support.
