A dish brush for conventional sweeping machines has a polygonal central base plate and trapezoidal demountable or removable segmental plates each provided with multiple brush plugs. I-shaped radial profiles are equispaced about the periphery of the base plate, are welded to apices thereof, and have respective axes radially directed toward a center of the base plate. The central base plate has contour edge plates 4 fixed to a planar center portion via two of the I-shaped radial profiles and inclined at an angle relative to the planar center portion. The demountable segmental plates are each slidable to mount between two I-shaped profiles and are each bolted to a respective one of the contour edge plates.
The invention relates to a further developed dish brush (1) for sweeping machines, wherein a central base plate (2) has in top view the form of a polygon with raised contour plates (4). Said raised contour plates (4) are mutually coupled with radially I-shaped radial profiles to take with a sliding movement the demountable segmental plate elements (3). So, a very effi- ciently constructed and environmentally friendly dish brush for sweeping machines is developed.
An expander roller for a fold-free expansion of foils, webs, and sheet materials in a width dimension. The expander roller has a central metal axle mounted in a surrounding synthetic tube with placed on its circumference a grid of implanted brush plugs in an axial direction under an angle alpha and with a mutual distancing and in tangential direction under a center angle beta and with a mutual distance. The roller provides a perfect expanding or stretching of thin widths of different materials.

The invention concerns a dish brush (1, 11) for conventional sweeping machines for cleaning, brushing or sweeping paved surfaces, wherein special constructed sweeping elements (4) and steel cable plugs (5) both waste and weeds remove from different types of paved surfaces. The mentioned sweeping elements (4) are fastened with welds (8,9) from the top side of the raised contour edge (2) through slit openings (6,7) and the steel cable plugs (5) are fastened with a weld (10) from the bottom side of said contour edge (2). The advantage is a well applicable sweeping and weeds removing dish brush (1,11) and which can be manufactured in a very economical way.
The invention relates to an improved composite brush core (1) for taking up not shown brush elements between connecting blocks (16). The brush core (1) composed of double-walled segmental parts (5) comprises between the inner wall (10) and the outer wall (11) two type of ribs (12,13) placed in alternate position for coupling said parts (2) in an easy way. In this way a brush core is obtained with a flexible desired length (L) for mounting to brush machines of various types.
