Abstract
Individual bristles and/or batches of bristles are withdrawn from one or more magazines and are mechanically or pneumatically transferred to positions of alignment with the sockets of one or more forms. The individual bristles and/or batches of bristles are thereupon drawn into the aligned sockets by suction prior to being welded or glued to an adapter which constitutes or forms part of a brush body and defines the open ends of sockets during drawing of bristles into the form or forms.
Claims70
A method of making brushes from bristles in at least one form which is permeable to gaseous fluids and has bristle-receiving open-ended sockets, comprising the steps of establishing and maintaining at least one supply of bristles;
- conveying predetermined numbers of bristles from the at least one supply to the sockets of the at least one form, including drawing air from the sockets through the at least one permeable form so that the bristles are introduced into the sockets by suction and portions of the thus introduced bristles are located at the open ends of the respective sockets;
- and enlarging said portions of the bristles at the open ends of the respective sockets.
Apparatus for making brushes from bristles, comprising at least one source of bristles;
- an assembling unit including at least one permeable form having bristle-receiving open-ended sockets;
- means for conveying predetermined numbers of bristles from said source to said sockets, including means for drawing air from said sockets through said form so that the bristles are introduced into the sockets by suction and portions of introduced bristles are located at the open ends of the respective sockets;
- and means for enlarging said portions of the bristles at the open ends of the respective sockets.
