  • the invention relates to a paint roller, in which one is made of plastic existing roller roller carries a cover on the outside, in which the Roller roller on both ends or end faces made of plastic existing existing closed circular bearing, at which the bearing is provided for supporting a bow bar and of the bow bar are penetrated and in which each camp one Forehead area and a hub area forms and with the hub area encloses a central long part to support the bow bar.
  • the invention also relates to a method for producing a such paint roller, in which a roller made of plastic is generated, for each end or end face the roller roller is a closed ring made of plastic Bearing that has a forehead area and a hub area forms, generates and is introduced into the roller roller, in which the roller roller is provided with a cover on the outside, in which a Central part is introduced into the two hub areas and the scar areas in a position enclosing a bow bar be brought and in which the central long part in the two Hub areas located on the roller roller inserted is in one hub area from outside the roller roller and in the other hub realm from within the roller roller.
  • paint roller of the aforementioned Each bearing is a separate one from the roller roller Part that forms an outer ring strip that goes into the roller roller is properly inserted and glued to it.
  • the roller roller is designed to match the parts to each other and the bearings are injection molded into molds.
  • the central part is the bow bar, which carries clamping sleeves, which in the hub areas are arranged and are rotatable therein.
  • the Manufacture of the known paint roller is expensive in that the roller roller, the bearings and the holding bushes or clamping sleeves by injection molding and that by separate injection molding processes must be generated to match each other to be assembled.
  • An object of the invention is therefore to provide a paint roller to create the kind mentioned in the manufacture under Avoiding injection molding is simplified.
  • the invention Paint roller is solving this task, characterized in that that at least one of the bearings one with the roller roller one-piece, with the formation of star-shaped folds is turned pipe piece.
  • the roller roller is first generated with the still cylindrical pipe section. Then it will Pipe section after a known manufacturing process inwards turned in, creating the star-shaped folds, i.e. it is folded in. So the camps are not produced by a separate injection molding process, which is the manufacture simplified. Compared to the assembly operations and gluing in is a simplified process. A pipe is drawn in at the end so that the bearing arises. The manufacture of the paint roller according to the invention is simplified by avoiding injection molding processes.
  • the the hub areas provided with the folds are elastic in diameter expandable and thus adapt to the diameter of the inserted Central long section, so that a dimensionally accurate Manufacturing by injection molding is unnecessary.
  • the roller roller can be produced by winding. Particularly useful and it is advantageous if the roller roller with the pipe section is made by extrusion. This simplifies the Production of the paint roller, that is, the production of the roller roller and the camp. One made by extrusion Due to its structure, plastic parts can be pulled through by one Differentiate injection molded plastic part.
  • the indented Pipe piece forms tongues delimited by the folds free end pieces represent the hub area.
  • This design too requires a simple tool for crimping and still gives a sufficiently stable and in terms of dimensional changes adaptable storage area.
  • the move in forms a polygonal cavity in which the central long part or Bow bar is arranged.
  • a particularly useful and advantageous embodiment of the The invention is when the cover is turned in at the front and on the outside of the hub area and the forehead area is pinched in the folds. Because of the The turning-in process is the transition from the roller roller to the forehead area rounded off with a relatively large radius. Since the reference with is turned in, it extends over this pronounced rounding.
  • the paint roller according to the invention with a coating is improved suitable for rolling out corners and the cover is by means of the folds held securely and firmly.
  • the is usually stored free end area of the inserted pipe section. So they store it Tips or end pieces of the tongues delimited by the folds. in the The case with the cover turned in is at the free end area or the tip-bearing area of the cover. This is also feasible if the bar is attached directly to it touches the adjacent area and the roller roller this adjacent reference area rotates relative to the bar.
  • the bow bar the central long part forming the indented hub area immediately adjacent when rotating on the hub area or an assigned reference area.
  • the roller roller rotates immediately on the bar, on which it is relatively loose or can sit with a lot of play.
  • the central long part is a tubular sleeve, which is the bow bar picks up and inserted into the indented hub area, from Hub area is seated clamped.
  • the bow bar is on the hub area supported only indirectly via the tube sleeve and in the tube sleeve rotatable, usually additional means for pivoting the bow bar are provided in the tubular sleeve.
  • the invention also consists in a method of the aforementioned Kind, which is characterized in that a tube length for the roller and at least one at both ends Bearing tube piece is generated and that the bearing tube piece into the roller roller to form star-shaped arrangements Wrinkles are turned over.
  • the camp is therefore one Known inversion process, which makes the overall production of the paint roller overall simplified considerably and is therefore cheaper.
  • the inversion process known per se is used, for example, in the Manufacture of a type of cartridge applied.
  • the cylindrical piece of pipe using a pressing tool to form a truncated cone shaped, the pressing tool going radially inward Has die cutting, which press in the folds.
  • a thrust ram moves in the axial direction against the smaller one free end of the truncated cone and presses it into the inside of the Roller roller.
  • the indentation operation is usually cold Plastic workpiece carried out and can also be heated Plastic workpiece can be carried out.
  • the pipe section that is turned over is closed over the circumference, i.e. not provided with gaps or slits as it is stable as a bearing have to be.
  • the thickness of the pipe section is usually the same Thickness of the roller roller, as this is the production of the bearing tube piece provided roller roller simplified.
  • the one with bearing pipe pieces provided roller roller is e.g. generated by stripes is wrapped.
  • the bow bar is circular in cross section and is usually made of metal and possibly also made of plastic.
  • the plastic of the roller roller is a thermoplastic.
  • roller roller corresponding extruded tube is extruded from the pipe length for the roller and its bearing pipe section is separated.
  • the roller roller provided with the bearing tube piece is not injection molded, but extruded, and this is a less complex creation process. Since it's because of Generation of the hub areas no longer increased by turning in Dimensional accuracy matters, is the production of the roller roller feasible by extrusion.
  • the tube by the meter is continuously provided with the reference when disconnecting the pipe length is also cut off.
  • the one on the meter tube applied cover is either tubular or made of Strips wrapped. In any case it is because of the yard goods Application of the cover simplified.
  • the length of the pipe section that is initially shaped into a truncated cone can be chosen as long as you want.
  • the press tool with the die cutting is for widely varying lengths of the to be deformed Pipe pieces designed. The shorter the pipe section or the Is the truncated cone, the larger after pushing in the truncated cone the hub area through hole. With getting longer Pipe piece can become narrowing storage area through openings produce.
  • the paint rollers according to the drawing each comprise a bracket 1, which forms a handle 2 and a round, straight in cross section Has bow bar 3 made of metal.
  • the bow bar 3 extends through in the middle or central, a cylindrical plastic Hollow roller roller 4, which has a cover 5 on its outer surface wearing.
  • the roller roller 4 takes one each on both end faces Plastic existing bearing 6 or 7, that of the rotatable support the roller roller opposite the bow bar.
  • There are Means are also provided to prevent undesirable axial displacement prevent the bow bar relative to the bearings, and these funds are explained in more detail below. In the embodiments 1 and 2, these means are against axial Moving metal clamping rings 8. In the embodiment according to FIG.
  • the other bearing 6 of the paint roller according to FIG. 1 is of one Inverted pipe section 9 formed with the roller 4 is in one piece and consists of a front area 10 and a hub area 11 exists, which merge.
  • the indented or folded pipe section 9 has distributed over the circumference in the Inside the roller roller 4 directed folds 12.
  • Camp 6 has reference 13 on the outside of the indented pipe section 9 on, in one piece with the reference 5 on the outer surface of the roller roller is.
  • the inlaid pipe section 9 forms with the free End of an edge 14 which defines a through hole, and has thus a very restricted hub area 11 with a relative small support surface.
