Abstract: A heater unit for heating flexible hair roller curlers includes two spaced pairs of side-by-side, elongated juxtaposed heat transmitting plates. The two plates of each pair are connected to each other in heat transmitting relationship to form a closed heat transmitting path and are so shaped and configured to form a plurality of individual hair curler receiving pockets therebetween. An electric heating element is positioned in the space between the two pairs of plates in heat conductive contact with the confronting plates thereof. The width of the plates is less than the length of the curlers so that the opposite ends thereof extend beyond the edges of the plates and are thus not heated thereby.

Abstract: A heater and holder for soft roller hair curlers includes a base having an openable top cover providing access to a shelf provided with at least one row of spaced holes of a size of to admit a hair curler. Each hole is aligned with an open-ended heat conductive metallic tube extending through a heat conductive metallic plate positioned below the shelf and having spaced top and lower panels with a first section of the tube extending upwardly from the top panel in alignment with the hole and a second section extending downwardly from the lower panel. A flexible electric heating element positioned in the space between the panels in a sinuous pattern heats the tubes and the curler inserted therein. The length of the tube is less than the length of the roller curler so that the opposite ends of the curlers are not heated so as to remain relatively cool whereby the heated curler can be easily handled.
