Device for the cleaning and opening of textile fibre materials, especially of the type resembling cotton, on cleaning installations

摘要

The invention relates to a device for the cleaning and opening of especially cotton-like fibre materials on cleaning installations, which comprises a rotating opening element and a combing strip assigned to this. According to the invention, the combing strip (3), assigned to the working surface of the opening element (10) in the region between feed rollers (2) and grid bars (12), is equipped with rows (9) of saw-like teeth (5). The tips (6) of the teeth (5) lie on an imaginary concave surface (16), and their height decreases in the direction of run of the fibre material. The rows (9) of saw-like teeth (5) form an acute angle ( alpha ) with the direction of run (14) of the fibre material. <IMAGE>
