Abstract
An apparatus for end-rounding bristles in a brush having different heights. The apparatus includes pins disposed in pre-determined locations such that they will contact selected bristles in a brush abutting the apparatus when the pins travel a two-dimensional path. The height of the pins is adjusted according to the heights of the selected bristles.
Claims39
An apparatus for end-rounding bristles for a brush, comprising:
- a plurality of pins disposed on a base;
- and
- an abrasive coating disposed on at least an end of the pins,
- wherein, when a plurality of bristles are disposed adjacent to the pins, two-dimensional motion of the base will cause the pins to polish ends of the bristles.
1 more element
A method of end-rounding bristles in a plurality of bundles, comprising:
- selecting a two-dimensional motion path for a plate;
- identifying a point on the plate that travels a path intercepting a position of a first bundle of bristles that is disposed in a polishing position with respect to the plate;
- and
- selecting an abrasive pin to place at the identified point having a height such that, when the first bristle bundle is disposed in the polishing position, the pin will polish ends of bristles in the first bristle bundle.
1 more element
A method of end-rounding a plurality of bristles, comprising:
- disposing ends of the bristles in a path of a translatable abrasive pin;
- and
