Patent number: 5104196Abstract: A brush filling machine is provided wherein two brush bodies are supplied at one time to one lateral gripping face of a rotary turret while two other brush bodies are being filled with fiber tufts on an adjacent lateral gripping face of the turret. The turret is indexed after each completed brush body filling cycle to present a new pair of brush bodies to be filled with fiber tufts by a pair of filling tools I. A specific arrangement of the various operating units of the machine is disclosed which permits the spacing a between the pair of filling tools, to be minimized thereby reducing the required radial dimensions of the rotary turret. Due to the low inertia of the rotary turret, the indexing thereof can be performed within the time of one filling stroke so that indexing of the turret causes no wait state of the filling tools.Type: GrantFiled: December 12, 1990Date of Patent: April 14, 1992Assignee: G.B.

Patent number: 5087403Abstract: Bristle articles can be manufactured in that the bristle carrier and optionally the ends of the bristles are melted and brought together under pressure, or the bristles are introduced into an injection or foaming mould for the bristle carrier and are embedded in the bristle carrier material by injection moulding or foaming. The cycle time of these processes is extremely long as a result of the thermal processes (heating, melting, injection moulding, cooling). It is possible to significantly reduce the same in that the tools for holding or producing the bristle carrier on the one hand and the clamping devices for the bristles on the other are moved on closed paths and the clamping devices at at least one common station are transferred to the path of the tools and at least during the thermal processes are jointly moved with the tools and are subsequently returned to their movement path.Type: GrantFiled: February 27, 1990Date of Patent: February 11, 1992Assignee: Coronet-Werke Heinrich Schlerf GmbHInventor: Georg Weihrauch
