Embossing Machine
Figs. 1 and 2 show a machine used for embossing elastic fabrics. It consists chiefly of a heavy frame A, a case hardened steel roll B on which the design has previously been engraved, and a hard paper roll C. The engraved steel roll B is heated with steam and may be subjected to heavy pressure by turning the hand wheels D.
When putting in a new design and accompanying paper roll, it is necessary to run the machine empty for a few hours, gradually applying the pressure at the hand wheels in order to mesh the design into the paper roll so as to get a strong impress on the goods. When moire-antique or water effects are desired, the embossing rolls are engraved with straight lines of the desired distance apart, and the goods are fed into the machine after passing over irregularly formed rollers, which prevent them from going through the machine straight. Fig. 3 is an example of this effect, with the gros grain in the middle water-marked, and bordered with a fancy effect not embossed.
