Definitions

  • the invention relates to plastic bristles for the washing brushes from automatic car washes to moving ones Brushes work.
  • Plastic bristles for washing brushes automatic washing systems that work with moving, generally rotating brushes, usually have a cross profile.
  • Bristles are for example in the DE-Z "damage of car paint when washing with synthetic bristles "(reprinted from - ATZ Automobiltechnische Zeitschrift, 71st year, No. 10/1969) described.
  • This cross profile should cause the paint surface a vehicle washing in automatic car washes less stressed.
  • EP-A 0 667 268 describes a brush roller of a car wash with thin, multiply folded strip-like hollow brushes, because of their broad strip-like shape a gentler To allow cleaning, without taking between vehicle parts to get into it and damage it.
  • the invention is therefore the object of the above to solve the mentioned problem.
  • This task is performed by plastic bristles for the washing brushes from automatic car washes to moving ones Brushes work and used hollow profile bristles, solved by that the hollow profile bristles have a round or oval cross-section have and that the hollow profile bristles in cross section a diameter in its longest direction of 0.5 to 5 mm, preferably 0.5 to 1.5 mm.
  • these bristles have the same diameter as the commonly used solid profile bristles (1.0 to 2.0 mm) less Mass up. This means that when washing in the car wash the impact energy of the bristles on the paint lower is. Scratching is less likely.
  • such profile bristles according to the invention have a similar stiffness compared to solid profile bristles. Such stiffness is important because most car washes are controlled by the contact pressure of the brush. If the modulus of elasticity of the plastic bristles, ie the stiffness, is too low, then the control of the system no longer works properly.
  • the advantage of the hollow profile bristles according to the invention is therefore in the much lower mass compared to the solid profile with similar stiffness of the profile bristle.
  • hollow profile frames deform elastically when impacted on the body in contrast to solid profile bristles. In conjunction with the lower mass, this leads to fewer scratches on the car paints.
  • the plastic bristles of the invention can be made of any commonly used materials such as LDPE or polyester, in particular PBT with an addition of 1 to 25 wt .-% polyurethane be prepared.
  • Preferred materials for the plastic bristles of the invention are polyamides or polyesters, preferably polyamides, which are selected from the group PA-6, PA-66, PA-610, PA-612. Of course, such materials can also be used in combination be used.
  • Other preferred materials are Polyester, in particular PBT, preferably with the already mentioned Addition of polyurethane.
  • the plastic bristles of the invention are preferably so in the brush used that the alignment of bristle placement or the bristle set transverse to a direction of rotation of the brush is selected.
  • the hollow profile bristles according to the invention can be of any shape exhibit. However, preferred are forms as shown in the attached Fig. 2, 3 and Fig. 8 are shown, in which case only the For simplicity, the outer circumference of the cross section is shown.
