Abstract (en)
[origin: EP0235543A2] The device consists of two rotatable half shafts between which the glass is held by at least one pot-like suction element or an adhesive block (2), which project into tapered slip-on sleeves (1) provided at their inner tapered surface with a radial serration and are driven by these slip-on sleeves (1) upon rotation, the outer tapered surface of the suction element or the adhesive block (2) being provided with a rim (18) consisting of radial ribs (19) projecting into the inner serration of the slip-on sleeve (1). The device is characterised in that only one (19a) of the radial ribs (19) of the ribbed rim (18), extending over a circle of 360 DEG , of the suction element or block (2) has a larger or smaller cross-section than the adjacent ribs (19), and only one (12a) of the recesses (12) of the slip-on sleeve (1) has a corresponding larger or smaller cross-section relative to the other recesses (12) of the sleeve (1).
