Abstract: Device for cleaning the guides of travelling flats in a flat carding machine, to eliminate from these deposits of foreign material found in the carded fibrous material, consisting in fitting the travelling flats assembly with flats provided with scraping or cleaning elements which come into contact with the surfaces of the guides on which the elements on which the flats rest are pulled.

Abstract: A flat card fed with fibers by means of a plurality of feed devices comprising licker-in rollers that operate in parallel so as to feed different fibers onto different points of the main carding drum, where the feed points are set sequentially and are staggered in such a way as to constitute, on the main carding drum, a series of pre-carding areas that are specific for the fibers fed at each point and that are provided with equipment adjustable for each type of fiber that is being processed.

Abstract: An opening machine for separating the fibres from intermingled impurities in cotton tufts comprises a storage bin into which cotton tufts to be processed are introduced, and an opening cylinder associated with cleaning blades for separating the impurities from the fibres and with suction openings for removing the impurities and the fibres separately. The opening machine comprises a pre-opening roller for performing a preliminary opening of the tufts. The cotton material is withdrawn from the bin by feed rollers, is processed by the pre-opening roller, and is introduced into a chamber in the form of pre-opened tufts. A final feed roller withdraws the tufts from the chamber and supplies them to the opening cylinder. The final feed roller works at a withdrawal rate greater than that of the feed rollers to prevent accumulation of the tufts in the chamber.

Abstract: A device and a process for controlling the motor drives (121) of textile machines, comprising at least one “encoder” (101), capable of controlling the number of revolutions of each motor (121), and at least one central electronic unit (111) processing the data originating from all the motor drives (121), based on an application program containing the synchronizing data between the individual motors (121) and the technological operating parameters of the textile machine.

Abstract: A control unit (10) for “pilgrim step” operation of the detaching cylinders (22, 23) in a combing machine, comprising a first electric motor, which rotates the circular comb (18) of the combing machine with uniform motion and a second electric motor (11), rotating a shaft (12), which houses the components to transmit motion to the detaching cylinders (22, 23). The first electric motor also operates at least one of the components that transmit motion to the detaching cylinders (22, 23), and the motor (11) is operated with a law of motion comprising acceleration and deceleration phases. Both motors mesh at all times and the first motor operates the components to transmit motion to the detaching cylinders (22, 23) by means of a differential device to obtain motion of the “pilgrim step” type.

Abstract: Device and process for cleaning web-squeezing rollers (5, 6) at output from a carding machine, and their scraper blades (17), in which the said blades are mounted so that they can move tangentially away from and up to the web-squeezing rollers (5, 6) and are equipped with nozzles (29) for blowing fluid into the gaps between the blades (17) and the rollers (5, 6) for removal of the material that accumulates in the said gaps.

Abstract: Automatic device for packing in a container, of the strip provided by a carding unit, consisting of an eccentric distributor which rotates relative to the collection container, which is rotated by an underlying rotary platform, and also comprises a device for movement and centring of the collection containers.

Abstract: Method and device for collection of the web at the output of a carder, and concentration of the web into a strip, in which the drawing is carried out simultaneously with the concentration of the web into a strip, between the compactor unit for the web and the pair of calenders of the discharge unit.

Abstract: Silo for supply of flock fibers to a carder, which silo is subdivided into superimposed chambers, between which there is interposed a set of rollers which regulate the descending flow, and carry out breaking and separation of the fibrous material, in which a supply roller, an auxiliary supply roller and a breaker roller are disposed in a triangle, in which the surface of the auxiliary roller opposite that which is tangent to the supply roller is exposed to the flow of air which descends downwards, together with the fibers worked by the breaker roller.

Abstract: Method and device for discharge and cleaning of the web produced by a carder, by the effect of suction applied to the web, in its passage from the detachment cylinder to the web-presser cylinders, preferably combined with drawing of the web in this section, by the effect of actuation of the web-presser cylinders, at a linear speed which is higher than that of the detachment cylinder.
