Curved brushes, process for making a twisted brush and device for making a twisted brush

摘要

The invention concerns a twisted brush (1) with a brush holder (2) of twisted wire sections (3),which have oval and /or elliptical cross -sections at least in the distal section (4) of the support (2).In addition, a twisted brush (1) is proposed, whose brush holder (2) has an extraction protection (12) at its proximal end (11).With the help of this extraction securing (12), the brush holder (2) can be set securely on the handle (7) of the twisted brush (1).In addition, a procedure for the production of a twisted brush is also proposed, with sections of wire (3), at least one of which is profiled,This means at least two areas (4a, 6a, 13a) with different cross -sections, to which the chest supports (2) are tripled.Another object of the invention is also a brush -making machine (20), which has a wire -forming device (19) with which in at least one area (4a, 6a,13a) a wire section to be profiled (3) a cross section of the wire section to be profiled (3) can be changed;so that the wire section (3) after profiling has at least two areas (4a, 6a, 13a) with different cross -sections.
