  • 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.
