Patent number: 6581248Abstract: A card is equipped with a regulating drafting system at the card delivery arrangement. The measuring values for regulating the drafting system are obtained from the drafted fibre sliver. The sliver depositing device can be pre-controlled relative to the drafting system in order to keep the stresses in the fibre sliver between the drafting system and the sliver depositing device within limits. A fibre sliver storage device (11) is arranged upstream from the regulating drafting system (13) with relatively small capacity. In order to enable timely action if long term deviations are detected in the fibre sliver mass (m) delivered, a sensor (10) can be arranged between the card (1) and the regulating drafting system (13), and the base rotational speed (U14) of the drive (25, 26) of the regulating drafting system (13) can be adapted based on signals transmitted by the sensor (10).Type: GrantFiled: September 5, 2000Date of Patent: June 24, 2003Assignee: Maschinenfabrik Rieter AGInventors: Christian Müller, Jürg Faas

Patent number: 6408221Abstract: To optimize the cleaning of cotton in a spinning milk, there is entered into a control original data concerning fiber characteristics and proportions of different types of contamination inherent to the origin of fiber cotton bales. Also there is entered into the control a desired degree of cleaning and a throughput quantity of the carded fiber sliver. The control delivers predetermined control signals based upon the entered original data, the throughput quantity of the carded sliver and the desired degree of cleaning. These control signals set adjustable operating members governing the rate of opening of the cotton bales by bale opening machines, the degree of cleaning of the cotton fibers by cleaning machines and the rate of processing of the cotton fibers by at least one carding machine.Type: GrantFiled: March 21, 1997Date of Patent: June 18, 2002Assignee: Maschinenfabrik Reiter AGInventors: Robert Demuth, Jürg Faas, Peter Fritzsche, Eduard Nüssli
