  • PROCESS AND AN APPARATUS FOR PRODUCING COARSE COUNT AND TRIDIMENSIONAL CRIMPED MULTIFILAMENT BCF YARNS, YARNS THUS OBTAINED AND APPLICATIONS THEREOF
    Publication number: 20190177885
    Abstract: The invention relates to a process and an apparatus for the production of coarse count and tridimensional crimped multifilament BCF (Bulk Continuous Filament) yarns, starting from polyamide 6.6, which envisages cooling in water and subsequent non-mechanical treatment with a mixture of air and steam, such that the yarns obtained have controlled chemical-physical and mechanical properties; the invention also relates to the yarns obtained by the aforesaid process and/or the aforesaid apparatus, both in a wound form in a cut form. The coarse count and tridimensional crimped multifilament BCF yarns having controlled chemical-physical and mechanical properties according to the present invention are suitable for non-textile applications and are preferably and advantageously employed in the manufacture of carpets for large surfaces.

  • System for producing a ring of abrasive sheet elements from which to form a rotary brush
    Patent number: 5992491
    Abstract: A method and system whereby an abrasive ring having an axis and a given number of abrasive sheet elements projecting with respect to the axis is formed by forming an orderly first pack of abrasive sheet elements having a first number of elements smaller than the given number of the ring; forming at least a second pack of elements having a second number of elements at most equal to the difference between the given number and the first number; curving the first pack to form a base ring; circumferentially compacting the elements in the base ring to form at least one gap; and inserting at least a second pack of elements inside the gap.

  • Method and machine for producing a ring of abrasive sheet elements from which to form a rotary brush
    Patent number: 5922160
    Abstract: A method and machine for producing a ring of abrasive sheet elements from which to form a rotary brush, and whereby the abrasive sheet elements are formed into an orderly row of abrasive elements of a length substantially equal to the mean circumference of the ring, and are connected to one another by feeding towards the row a flexible connecting element, and by connecting the flexible connecting element integrally to each of the sheet elements prior to curving the row to form the ring.
