With this construction, the strip. It permits the wick to be adjusted to fit the circumference of the burner groove. The strip I3 holds the outer face of the hem 9 pressed against the adjacent face of the burner groove, thus providing a uniform area allarouncl the "groove for the unobstructed flow of gas along the bottomof the groove and upwardly under the actionpf the usual air currents.

1 The strip l3 stiffens the upper edge of the ,wicklil'so that it may be constructed to stand above the adjacent shoulderM upon which the 'iburner sleeve 25 rests without danger thatthe wick may become lodged between the shoulder 24 and the sleeve 25. The height of the wick and the width of the hem 9 creates an extraordinary the ring-like flows to thelarge amount of oil burning surface which insures that the burner may be heated quickly to a temperature at which the distillate vaporizes.

What is claimed as new, is; 1. A tape for a distillateburner wick comprising a substantially rectangular, thin body of absorbent, non-combustible material having a hem along at least one longitudinal edge and a stiffener run through the internal passage in the hem.

I 2. A tape for a distillate burner wick comprising a substantially rectangular, thin body of absorbent, non-combustible material having a hem along at least one longitudinal edge and a stiffener longer than the. tape run through the internal passage in the hem.

3. A distillate burner wick comprising a ring formed from a substantially rectangular, thin body of absorbent, non-combustible material having free ends and a hem along at least one longitudinal edge and means for maintaining the free ends in a predetermined relative position comprising a stiifener longer than the tape run through the-internal passage in the hem, the

opposite ends of the stiffener being overlapped Within the hem. r
