Abstract
A method of, and apparatus for, fabricating a bristle support or carrier for a brush, especially a hair brush, having pin-like bristles is disclosed. In a first method step there are produced the rows of bristle pins interconnected with one another at their rear end by means of a web. The individual bristle pin rows are retained in their position after forming the same to accomplish the next method step. In this next or second method step the bristle pins, at the region of their rear end, together with the webs, are cast in the material of the bristle support, so that the bristle pin rows are embedded in the bristle support.
