Abstract
A brush conveyor, such as a velvet needling machine, has an assembly of contiguous brushes disposed in transverse rows, and a drive source for this assembly of brushes which forms a conveying plane having a predetermined direction of displacement to constitute an upper face of the conveyor. Each brush includes a body including, on its upper face, holes which are provided for receiving a tuft of hair and, on its lower face, connecting apparatus to fasten this brush to a drive source. The drive source has several parallel drive belts or chains placed between at least two drive cylinders running in the same direction. The conveyor also has a support structure for supporting the brush bodies forming the conveying plane. This support structure includes a support table having several flat support parts separated by spaces provided for the drive belts or chains. With each transverse row of brushes a connecting rail, attached to at least one brush in a row, extends along the width of the conveyor, disposed perpendicular to the direction of displacement. The connecting rail is also attached to the drive belts or chains.
