Patent number: 8261646Abstract: Transversal cutting machine comprises feeding means (20) that supply a log of paper (15), for example hygienic paper, to a sawing station at which rolls or stacks (16) are cut off from the log (15) by a blade (25). During the cutting step the log (15) is held by a clamping device (1), divided in two parts (2, 3) arranged respectively upstream from and downstream of a slit (17) through which the blade (25) passes. In particular, the first part (2) and the second part (3) of clamping device (1) are movable relatively so that during the cut the log (15) is locally subject to traction at the same time of the blade (25) driven in the log. This way, during the cutting action of the blade (25) an opening (17) is created on the log (15) having a size at least the same as the thickness of blade (25) same. This makes easier the action of blade (25) since it reduces the friction produced between the blade (25) and the log (15).Type: GrantFiled: March 9, 2005Date of Patent: September 11, 2012Assignee: MTC-Macchine Trasformazione Carta S.R.L.Inventor: Alessandro De Matteis

Patent number: 4063480Abstract: Filter rod portions in the flutes of a rotating drum are severed by a rotary disk-shaped knife to yield shorter sections which are used for the making of filter cigarettes. During severing, the filter rod portions are flexed by stationary components to produce tensional stresses in those parts of filter rod portions which move into the range of the knife. This enables the knife to make a clean cut and to become immediately separated from the shorter sections. The stationary components may include annular members which urge the outer parts of successive filter rod portions against sloping portions of bottom surfaces of the respective flutes. If the depth of the flutes is constant, the components further include stationary cams which extend into circumferential grooves of the drum and lift the central parts of successive filter rod portions out of the adjacent portions of the flutes during travel past the knife.Type: GrantFiled: April 30, 1976Date of Patent: December 20, 1977Assignee: Hauni-Werke Korber & Co., KGInventor: Alfred Hinzmann
