Abstract (en)
[origin: EP0394637A2] The hollow cylinder 2 has an inner body 3 whose part-cylinder surface 12, which is arranged centrally with respect to the hollow cylinder 2 and made with a smaller radius than the inner radius of the latter, forms a sickle-shaped space in which a vacuum is generated upon rotation of the hollow cylinder 2. Air is thereby extracted through the bores 11 of the hollow cylinder from the region in which a web encompasses the hollow cylinder 2. This results in a firmer adhesion of the web on the hollow cylinder 2. <IMAGE>
