ABSTRACT:
A simplified, low-cost method and apparatus for transferring inked design images from preprinted, design bearing waxed sheets to elongated, cylindrical, solid wax candle bodies or the like which permits gravure or lithographically applied halftone and shaded design images to be used as candle decorations, eliminates costly and tedious manual operations characteristic of decal applications and other prior methods and devices, and produces a finished candle having perfectly aligned decorative images thereon which are not susceptible to undesirable torching as the candle burns. The method comprises applying a design-bearing, waxed sheet to the candle body in closely conforming relationship thereto while the latter rotates in pressurized, bridging engagement between a pair of spaced, adjacent, rotating transfer rollers. Heat is applied to the sheet through one transfer roller to thereby effect transfer and partial wax encapsulation of the design image on the candle body, whereupon the transfer sheet is stripped from the candle and discarded. Means are also provided for sequentially heat treating separate candles to remove surface irregularities thereon, followed by water-cooling and air drying thereof prior to the image transfer step. Novel ink formulations are also disclosed which are especially adapted for gravure printing of design images onto waxed subtrates without smearing or offsetting thereof, and which facilitate ultimate transfer to solid candle bodies.
