Definitions

the invention relates to a brush roller, comprising a hollow cylinder on the end, which is held in bearings and rotates about its axis and is provided in the region of its outer circumference with a set of bristles projecting radially outwards.
Such a brush roller is known. It is made of metal and has an extremely high moment of inertia, which requires great forces when accelerating and braking.
the hollow cylinder consists of a polymeric material.
the mass of inertia of the brush roller is thereby greatly reduced, which allows large accelerations and decelerations to be achieved with a small expenditure of energy.
the hollow cylinder has at least one metallic counterweight on the radially opposite side of the bristles, which is embedded in its wall.
the counterweight does not appear to the outside in such a design, which simplifies balancing and risk of accidents be avoided.
the counterweight can also fully compensate for the imbalance caused by the asymmetrical distribution of the bristles.
Brush rollers with an asymmetrical distribution of the bristles are used, for example, in sheet feeders of printing presses. They are usually only provided with a single row of bristles, which is attached at a peripheral location. In such designs, the counterweight is expediently of a strip-like shape and runs parallel to the bristles.
the polymeric material from which the hollow cylinder is produced can be reinforced by fibers and / or threads embedded therein. This allows the strength properties to be markedly increased, in particular in the case of designs in which fibers and / or threads of higher strength are used, for example those made of carbon and / or glass.
the roller body is preferably made of epoxy or phenolic resin.
the bristles are provided with threaded receptacles that can be screwed into the hollow cylinder. Different methods for fixing the bristles are of course also possible.
the brush roller shown in Fig. 1 consists of a hollow cylinder 2 rotatable about its axis, which consists of epoxy resin and is reinforced by fibers 5 embedded therein.
the hollow cylinder 2 is at a circumferential location with one parallel to its axis extending row of bristles 3, which are held in grub screws 6 and are held by means of the grub screws 6 by screwing into threaded holes of the hollow cylinder 2.
the hollow cylinder 2 has on the radially opposite side of the bristles 3 a metallic counterweight 4 which is embedded in its wall and which consists of a sheet metal strip made of steel.
the counterweight 4 is dimensioned such that it cannot be seen from the outside. The balancing and storage of the hollow cylinder 2 is greatly simplified. Furthermore, the occurrence of accident hazards is optimally prevented.
FIG. 2 the brush roller according to FIG. 1 is shown in a longitudinal section.
the end bearing 1 in the embodiment shown consists of end shields which are glued to the hollow cylinder 2 and in turn are accommodated in block bearings. Different designs of bearings are of course also possible.
