Carding engine is fitted with one or more electrodes at fiber transfer zones to give adjustable controlled fields to determine the electrostatic adhesion to prevent fibers clinging to rollers and the transport assembly

摘要

The carding engine has at least one electrode (6), which generates a field at the transfer zone from the doffer roller (3) to the following compression roller (4). The electrode produces an ion field which gives an adjustable electrostatic control on the adhesion of the fibers and the fiber web on the rollers (3,4) and/or the transport assembly (7). A number of electrodes (6) are at the same or different rollers (3-5). At least one electrode (6) is at the transfer between the take-off roller (5) and the transport assembly (7). The electrodes (6) operate with a high voltage. The ionizing electrode (6) is fed with a cycled direct voltage.
