摘要:
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.
摘要:
Device for processing the web of fibers obtained from a carder, by transforming it into a strip, subjecting it to drawing, and collecting it in a container, in which the drawing means consist of a plurality of drawing stations, each of which comprises two or more pairs of rollers, each of which is actuated by its own motor, and is piloted by a control unit which distributes the drawing between the stations.
摘要:
A device for monitoring and regulating the tension in the sliver produced by a carding unit and transferred from this along a path to a unit for its collection into cans for further processing, comprising a deviator bar pivoted on a pivot and an oppositely located rod provided with an element which opposes the rotary movement of the bar deriving from the variations in tension of the sliver deviated by it, the sliver tension being measured by sensors on the basis of the effect induced by the sliver on the bar, the relative signals being transmitted to the control unit which compares the values received with the allowable limiting values and implements the consequent interventions.
摘要:
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.
摘要:
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.
摘要:
An automatic device for gathering and packaging card sliver in cans, the device having a plurality of gathering stations for cans of different size that have a rotary platform (35, 45) set underneath for rotation of the can receiving the sliver and of a distributor (50, 50′) set above and driven by a motion of revolution, in which the cans are moved according to a single common path and with common members for imparting movement and for driving.
摘要:
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.
摘要:
Method and device for collection of the web, and drawing of the latter into the output unit of a carder, in which the drawing is subdivided for a first part between the compactor unit for the web and the first pair of drawing rollers for the strip, and a second drawing part between the rollers of the drawing unit for the strip.
摘要:
Flat carder in which the main carding drum receives the fibers from a multiple number of briseurs operating in parallel to feed the main carding drum at different points. Each briseur or opening cylinder is equipped and actuated independently from the other.
摘要:
A cogged-belt drive device for drawing along mobile flats of flat cards, in which the cogged belts are equipped, in their development facing the flat guides, with scraping or cleaning elements that eliminate the accumulation of foreign bodies from the guides on which the resting elements of the card flats are drawn along.
