1. An electrical smoking article for generating a tobacco flavor substance from a web having tobacco flavor medium therealong comprising:
- a source of electrical energy;
electrical heating means;
means for supporting a section of the web in thermal proximity to said electrical heating means;
means for advancing the web to present a successive section of the web having the tobacco flavor medium therealong to said electrical heating means; and
control means for applying electrical energy from said source of electrical energy to said electrical heating means for a predetermined period of time to generate a tobacco flavor substance from the section having tobacco flavor medium therealong for delivery to a smoker; and
means for actuating said advancing means independently of applying electrical energy to said electrical heating means to present the successive section of the web to the electrical heating means.

Abstract
An electrical smoking article is provided in which tobacco flavor medium is carried past a heater by a continuous web. The web, which preferably is substantially non-combustible, may bear continuous tobacco flavor medium or spaced-apart portions of tobacco flavor medium. A flavor cassette for such an electrical smoking article is also provided. The cassette resembles a conventional recording tape microcassette, having the web in place of magnetic tape. The cassette may also include the heater past which the tape is indexed to heat individual portions of tobacco flavor medium.
