Abstract
An apparatus for manufacturing a brush-type seal comprising wrapping a filament over two spaced elongated mandrels in parallel arrangement to form a filament packing, then securing the filament packing at its ends onto the two mandrels, thereafter dividing the filament packing in a median plane between the mandrels to produce two brushes which are then bent into the desired brush shape. The bristles can be formed at an inclination in their mountings by supporting the mandrels on the base beams of a parallelogram linkage which can be displaced and controlled by cam disks so that the length of winding of the filament remains constant.
