Abstract
Non-slipping wheel (1) comprising an elastomer layer (3) which covers at least the radially outer part of the wheel, characterized in that the elastomer layer has been provided with bubbles which are continuously torn open during use of the wheel thereby generating a suction effect. The bubbles can be provided by foaming the elastomer. The elastomer can be polyurethane, and the wheel can further comprise an inner core layer (2) of a different material which is elastic, e.g., rubber. The wheel is particularly useful for floor cleaning machines: due to their use on ground which is covered by a cleaning solution, the wheels face traction problems—on the other hand, the wheels should not leave additional residues or markings on the floor.

Non-slipping wheel comprising an elastomer layer which covers at least the radially outer part of the wheel, characterized in that the elastomer layer has been provided with bubbles which are continuously tom open during use of the wheel thereby generating a suction effect and enhancing the roughness of the outer surface of the wheel.
Method for manufacturing a non-slipping wheel, comprising the following steps:
- providing an elastomer and creating bubbles therein;
- applying a radial inner wheel core to a rim and grinding or polishing the radial outer surface of the inner core in order to obtain a surface appropriate for gluing or vulcanizing;
- gluing the radial outer surface of the core together with the foamed elastomer or vulcanizing the latter thereto such that a radial outer elastomer layer containing the bubbles is formed which are continuously torn open during use of the wheel thereby generating a suction effect and enhancing the roughness of the outer surface of the wheel.
