Abstract: A double molding process whereby at least one sign is produced on a product while the product is molded. The product has an inner core and an outer cover. In the process, the inner core is molded with a first molding material. The inner core has at least one side provided with a groove in the shape of the sign to be produced. The inner core also has at least one other side provided with at least one channel leading within the inner core to the groove. The outer cover is then molded onto the inner core with a second molding material in such a manner that the one side of the inner core is not covered by the second molding material and thus remains visible. The channel of the other side and the groove of the one side are both filled up with the second molding material to produce the sign on the side of the product.

Abstract: A sanding tool having a plate with opposite sanding and supporting sides, a handle mounted onto the supporting side of the plate, and at least one fastening device operatively connected to the supporting side of the plate for fastening a sandpaper onto the sanding tool in such a manner that most of the sandpaper rests against the sanding side of the plate. Each fastening device has a clamping device and a guiding device. The clamping device is movable with respect to the supporting side of the plate between a first position where the clamping device is away from the supporting side and a second position where the clamping device rests operatively against the supporting side. The guiding device is used for guiding movement of the clamping device along a predetermined path between the first and second positions. In operation, a portion of the sandpaper is removably clamped between the supporting side of the plate and the clamping device when the latter is in the second position.
