Abstract

132,804. Wenschow, K. Feb. 14, 1918, [Convention date]. Embossing and forming.-A process of making relief maps, pictures, designs, &c. consists in placing a pattern in a frame, rendering it elastic by impregnation or otherwise, covering its back with a plastic mass while it is in an inverted position, allowing it to sag under the weight of the mass, and then embossing it with hand-tools or a matrix. The pattern a, of paper, silk, linen, &c., is clamped in a frame b, c in an inverted position, and a plastic mass d resting on the pattern causes it to sag. The relief is then produced on the pattern from below by hand-tools or by a matrix f. A cover frame c having a perforated hinged part e<1> may be placed on the frame b, c, and the whole is then inverted and the pattern is produced from above. Instead of the cover frame e, a matrix may be used to co-operate with the matrix f. After a pattern has been transformed into a relief, the plastic mass may be allowed to harden to form a matrix for the production of other matrices, between which patterns may be forced to form reliefs without the use of a plastic mass.
