PCT No. PCT/EP95/02474 Sec. 371 Date Dec. 16, 1996 Sec. 102(e) Date Dec. 16, 1996 PCT Filed Jun. 26, 1995 PCT Pub. No. WO96/00544 PCT Pub. Date Jan. 11, 1996A machine for manufacturing adhesive dressings having an adhesive support, absorbing material compresses laying on the support and a protective layer, includes a cutting element for cutting compresses to a desired size and placing them at the desired intervals onto the adhesive layer. The cutting element includes a first cylindrical counter roll that has a smooth surface and a second roll acting on the first roll. The second roll has projecting sectors, alternated with recessed sectors, provided with at least a transversal cutting knife for cutting the absorbing tape by compressing the same against the counter roll. The tape is drawn during the synchronous rotation of the rolls by the projecting sectors cooperating with the surface of the counter roll. Each knife is positioned close to the transition region between a projecting sector and a subsequent recessed sector to provide a trailing projection portion for each projecting sector so that the absorbing material compresses are held between the first and second rolls by the trailing portion after being cut and before being supplied to the adhesive support.
