Abstract
A carding machine comprises a main drum fed by a feed system with roughly attenuated and cleaned fibers, a plurality of fixed clothed segments, and opening cylinders or briseurs which feed the said main drum at different points of the main drum. The machine is characterized in that it comprises a first set of moving flats which performs a first, gentle parallelization and a second set of moving flats which carries out another parallelization that is more aggressive than the first.
Claims23
A carding machine comprising a main drum fed by a feed system with roughly attenuated and cleaned fibers;
- at least one system of flats for carding the fibers, the at least one system of flats acting on the main drum wherein the feed systems comprises at least two briseurs which feed the main drum at different points of the main drum, and wherein the system of flats comprises a plurality of sets of moving flats arranged downstream of the briseurs, wherein each of the sets of moving flats is capable of moving both against and with a direction of rotation of the main drum.
A carding machine comprising:
- a main drum fed by a feed system with roughly attenuated and cleaned fibers, wherein the feed system comprises at least two briseurs which feed the main drum at different points of the main drum;
- and
- at least one system of flats for carding the fibres, acting on the main drum, wherein the system of flats comprises a first set of moving flats and a second set of moving flats arranged downstream of the first set of moving flats and wherein each set of moving flats has a covering provided with a plurality of teeth having a predetermined population, the population of teeth on the first set of moving flats being less than the population of teeth on the second set of moving flats.
A carding method comprising the steps of:
- feeding a main drum of a carding machine with a first stream of fiber in a thin layer to a first point of interaction with the main drum;
- feeding the main drum of the carding machine, simultaneously with the first stream, with a second stream of fiber in a thin layer to a second point of interaction with the main drum, the second point of interaction being downstream of the first point of interaction;
- performing on the fiber carried by the main drum a first parallelization by means of a first set of moving flats having a covering provided with a plurality of teeth having a predetermined population;
- performing on the fiber carried by the main drum a second parallelization by means of a second set of moving flats situated downstream of the first set of moving flats, the second set of moving flats having a covering provided with a plurality of teeth having a different population than that of the first set of moving flats wherein the first parallelization is less thorough than the second parallelization;
- and taking the thin layer of parallelized fiber from the main drum by means of a doffer system.
