Process and apparatus for operating a machine of the tobacco processing industry. The process includes guiding at least one wrapper strip along a conveyor path from a wrapping strip supply to a garniture device, and fixing the at least one wrapper strip in at least one preset position along the conveyor path The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

The leading end of a running fresh web of cigarette paper or the like is spliced to the trailing end of a running expiring web while the ends travel at the same speed, in the same direction and next to each other. The splicing unit includes a rotatable roll at one side of the path for the advancing ends, and a rotary carrier at the other side of such path opposite the roll. The carrier is provided with a segment having a convex knurling surface which cooperates with the peripheral surface of the roll to provide the webs with a splice while the segment engages the adjacent web. Prior to splicing, the carrier is rotated in a first direction to move the segment away from the path for the webs, and such movement is followed by rotation of the carrier in a second direction to accelerate the knurling surface at least close (a) to the common speed of the webs and (b) at least close to the speed of the peripheral surface of the roll. Those remnants of the webs which project beyond the splice are separated from the webs, preferably by tearing.

Method of and apparatus for splicing running webs of paper and the like

The invention relates to a process and to a machine for splicing the trailing end of a running expiring web (e.g., a web of cigarette paper) to the leading end of a fresh web while the ends of the webs travel next to each other, in the same direction and at an at least substantially identical speed between a rotary knurling surface and a complementary second rotary surface which may but need not be a knurling surface. The rolls which constitute or mount the carriers for the two surfaces are driven in such a way that each n-th (e.g., each tenth) revolution results in the making of a splice between the leading and trailing ends of the webs. The forwardly and/or rearwardly extending remnants of the fresh and expiring webs are torn off the spliced-together webs at the respective ends of the splice.

A machine tool, particularly a grinding machine, wherein one or more machine elements (such as a wheelhead, a table or a saddle) are movable along guideways in or on the machine frame. Each of the guideways is overlapped or shielded by a guard, and each guard is movable by a discrete prime mover in synchronism with the respective machine element so that the width of clearances (if any) between the guards and the respective machine elements remains constant. The provision of discrete prime movers for the guards ensures that the machine tool can treat workpieces with a higher degree of accuracy because the prime movers for the machine elements are not affected by the weight, inertia and/or other parameters of the guards.
