Appeal No. 2003-1575 Page 6 Application No. 09/420,306 invention wherein the forward roller 30 is outside the suction chamber 56 and the rearward roller 31 is within the suction chamber 56. Bleeker teaches (column 7, lines 52-65) that the forward roller 30, viewed in the given operating direction 29, is wholly made of a comparatively hard material, the circumferential surface 37 of the roller 30 advantageously having a surface roughness ranging between 0 µm and 2 µm. The interior of the rearward roller 31, viewed in the operating direction 29, is also made of a comparatively hard material but is surrounded by a shell of a comparatively soft material, the circumferential surface 38 of the rearward roller 31 having a higher surface roughness than the circumferential surface 37 of the forward roller 30. The surface roughness of the circumferential surface 38 of the rearward roller 31 may range approximately between 3 µm and 6 µm. Bergmann discloses an apparatus for shampooing, which may be used for this purpose alone, or for simultaneously shampooing, beating and rubbing the body. The apparatus as shown in Figure 9 includes a knobbed roll a, a smooth roll c and a handle g. Bergmann teaches (page 2, lines 41-44) that (1) the knobbed roll a consists of a metal core provided with a knobbed covering of india rubber or other suitable material; and (2) the smooth roll c is made of metal covered with wash leather or other similar soft material. In the rejection of claim 4 in the answer (pp. 3-4), the examiner (1) ascertained that Bleeker differs from the present invention in that Bleeker's rearward roller 31 has aPage: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
