Abstract
1,142,785. Tobacco smoke filters. COURTAULDS Ltd. 3 June, 1966 [4 June, 1965], No. 23870/65. Heading A2C. [Also in Division D1] Cigarette filter tips are made by spraying with plasticizer a crimped cellulose acetate tow made by spinning cellulose acetate from a number of individual jets, combining the separate ends into a compact ribbon or rope, opening the ribbon or rope into a band, crimping the opened band of tow, and further opening the tow by conventional means. A ribbon of tow may be produced by laying a relatively small number of ends side-by-side in each of a number of layers. Suitably, the tow is opened by passage over one or more guide bars of curved profile, especially two or more guide bars. The opening guide bars may be preceded by a roller over which the ribbon or rope of tow passes with some lap, or by a pair of nip rollers through which the tow passes. The tow may be opened by an air spreader after passage through a pair of nip rollers at which the tension is relaxed, and is desirably crimped substantially immediately after opening.
