Abstract
There is disclosed a process for manufacturing a body of fibers for use in a brush as well as the brush so produced. This process comprises inserting a plurality of fibers into an opening of a plate, separating the fibers into a plurality of fiber bunches or curtains, applying an adhesive to the end of the fibers which is at the base of the plate, and removing the body of fibers from the plate, such that the body of fibers contains at least one parallel space or passage between the curtains of fibers. The body of fibers is then inserted into a brush handle. This brush may be used to apply coating liquids such as paints and varnishes.
Claims9
A process for manufacturing a body of fibers for use in a brush for applying a coating liquid to a surface, which process comprises
- (a) inserting lengthwise a plurality of fibers into the elongated opening of a plate such that said fibers are tightly held within said opening,
- (b) separating said fibers into a plurality of curtains by inserting separation means into the end of said fibers, said end being opposite from the end which is inserted in said plate, said separation means causing said body of fibers to be separated by at least one space or passage between said curtains of fibers, said separation distance being such that substantial dripping of said coating liquid does not take place,
- (c) maintaining said separation means within said fibers while applying to the ends of said fibers which are at the base of said plate means for adhering substantially all of said fibers into a body of fibers,
- (d) removing said separation means from said body of fibers, and
- (e) removing said body of fibers from said plate, such that said body of fibers contains at least one space or passage between said curtains of fibers.
A process for manufacturing a paint brush comprising
- (a) inserting lengthwise a plurality of fibers into the elongated opening of a plate, such that said fibers are slightly held within said opening, said opening being such that it has a smaller perimeter at its base than at its top,
- (b) separating said fibers into a plurality of curtains by inserting separation means into the end of said fibers, said end being opposite from the end which is inserted in said plate, said separation means comprising a comb with at least one board tooth having a blunt edge or end, and said separation means causing said body of fibers to be separated by at least one space or passage between said curtains of fibers, said separation distance being such that substantial dripping of said coating liquid does not take place,
- (c) maintaining said separation means within said fibers while applying to the ends of said fibers which are at the base of said plate means for adhering substantially all of said fibers into a body of fibers,
- (d) removing said separation means from said body of fibers,
- (e) removing said body of fibers from said plate by pressing said body with ejector means which comprise a male punch for pushing said body of fibers out of said elongated opening of said plate and guide means which may be inserted through holes which are contained in said plate, such that said body of fibers contains at least one space or passage between said curtains of fibers, and
- (f) inserting said body of fibers within a cavity which is contained within a brush handle, said cavity containing arrow shaped projections for holding said body of fibers within said cavity.
