摘要:
A method for the manufacture of scrubbing brushes and/or painting brushes is provided, in which a processing pressure exerted by a processing tool (3, 4) onto a bristle holder (5) to be processed is determined by a pressure sensor (6), which has a pressure-recording surface (7), which is arranged behind the bristle holder (5) to be processed, in the operating direction of the processing tool (3, 4). In this manner, determination of the processing pressure is possible close to the bristle holder (5) to be processed.
摘要:
Device for manufacturing brushes by means of successive operations, which mainly consists of a number of brush holders (9-11) which are provided on a means of transport and which can be moved between different posts (5-8) which are provided along the means of transport, more particularly working posts (6-8) where a processing can take place and/or waiting posts (5) where the brush holders (9-11) can be put in a wait position, characterized in that the means of transport is provided with means which make it possible to move the brush holders (9-11) independently from one another.
摘要:
A brush with a one-piece plastic brush body produced by injection moulding comprises a head covered with bristles and a dimensionally stable handle with a larger cross-section than the head, the brush body being made from an elastomer mixed with a foaming agent and the plastic is foamed in an area of the handle and is solid in the area of the head. The brush is produced by injection moulding in a two-part mould. An elastomer and a foaming agent are mixed during moulding. The mould cross-section for forming the head is smaller than the mould cross section for forming the handle with the elastomer being only foamed in the area of the handle.
摘要:
A brush backing of relatively rigid foamed cellular polyurethane is pierced at a plurality of locations to form openings for receiving unitary bristle tufts. The piercing action creates barbs in the backing which firmly secure the tufts. The pierced openings may be formed to receive circular as well as flat tufts.
