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.
Claims9
A method of producing a ring of abrasive sheet elements from which to form a rotary brush having an axis and an abrasive ring where the abrasive ring includes a given number (N) of abrasive sheet elements substantially projecting with respect to said axis, the method comprising the steps of;
- a) forming an orderly succession of abrasive sheet elements;
- b) forming a first orderly pack of said abrasive sheet elements comprising a first number (N1) of elements smaller than said given number (N);
- c) forming at least a second pack of said elements comprising a second number (N2) of elements at most equal to the difference between said given number (N) and said first number (N1);
- d) forming a base ring by curving said first pack;
- e) circumferentially compacting the elements in said base ring so as to form at least one gap;
- and
- f) inserting at least a said second pack inside said gap.
