Abstract: A rotary cutting device is provided, which comprises a first and a second roller mounted rotatably on a machine stand. Either the first roller is a tool roller and the second roller is a counter-roller, or the second roller is a tool roller and the first roller is a counter-roller. The second roller is mounted on the machine stand to be displaceable on a first displacement axis. A cutting pressure device is provided by way of which a cutting pressure can be exerted between the second roller and the first roller. In a support mode, the second roller is supported against a wedge device. The wedge device has at least one displaceable wedge element. A position of the at least one displaceable wedge element predetermines a spacing between the second roller and the first roller. A drive device enables movement of the at least one displaceable wedge element.

Abstract: A rotary cutting is provided which includes a machine frame, a cutting roll rotatably mounted on the machine frame, and a counter roll mounted on the machine frame. The cutting roll and/or the counter roll are formed from an inner core and an outer sleeve disposed around the inner core. The outer sleeve is spaced apart from the inner core. At least one counter bearing is disposed on the inner core, on which the outer sleeve is supported.

Abstract: The invention relates to a rotary cutting device comprising a rotatable cutting tool and a rotatable anvil roller incorporating a cutting support, wherein a cutting edge, which co-operates with the cutting support, is arranged on the cutting tool for cutting a web of material, and wherein at least one support ring with a support surface is mounted on the cutting tool for supporting the cutting tool relative to the anvil roller.

Abstract: A rotary cutting device is provided comprising a rotatably mounted cutting roller and an anvil roller. At least one support ring is provided for supporting the cuffing roller on the anvil roller. A lifting device is provided for moving the cutting roller and the anvil roller apart.

Abstract: In order to provide a cutting device, comprising a machine frame, an anvil roller which is mounted for rotation on the machine frame and a cutting tool which is mounted for rotation on the machine frame, wherein the cutting tool has a cutting edge cooperating with anvil surfaces of the anvil roller, with which the springing away on account of lateral cutting forces is minimized it is provided for the cutting tool to be biased essentially parallel to its axis of rotation.

Abstract: In order to provide a rotary cutting device comprising a rotatably mounted cutting roller and an anvil roller wherein at least one support ring is provided for supporting the cutting roller on the anvil roller such that the device has increased freedom from malfunction, it is proposed that a lifting device be provided for the purposes of moving the cutting roller and the anvil roller apart.

Abstract: A cutting machine includes an anvil roller rotatable on a machine frame about an axis of rotation. The anvil roller has an anvil surface. A cutting tool is mounted on the machine frame for rotation about an axis of rotation, with a cutter interacting with the anvil surface and with supporting rings which are held on the cutting tool and support it relative to the anvil roller with their supporting ring surfaces and/or vice versa. The quality of the cutting effect can be maintained even when the cutter becomes worn, by enabling the diameter of the supporting ring surface of each supporting ring to be adjustable by radial expansion and contraction.

Abstract: In order to so improve a cutting machine comprising a machine frame, an anvil roller rotatable on the machine frame about an axis of rotation and having an anvil surface, a cutting tool mounted on the machine frame for rotation about an axis of rotation, with a cutter interacting with the anvil surface and with supporting rings which are held on the cutting tool and support it relative to the anvil roller with their supporting ring surfaces and/or vice versa, that the quality of the cutting effect can be maintained even when the cutter becomes worn, it is proposed that the diameter of the supporting ring surface of each supporting ring be adjustable by radial stretching of the supporting ring within the range below an elastic expansion limit of its material by means of an expansion device.

Abstract: A device for cutting to shape advancing material webs, in particular made of fibrous materials, comprises a rotatingly driven shape cutting roller and a rotatingly driven counter cutting roller. The shape cutting roller has a shape cutting edge and the counter cutting roller a smooth cylinder surface. Both rollers are mounted in a machine frame by means of pivot bearings, and the distance between the axes of the rollers is adjustable. The rollers are rotatably mounted in separate, first and second machine frame parts which, for their part, are supported on a common machine base. One of these machine frame parts is held on an adjustable wedge-shaped guide means for adjusting the distance between the axes of the rollers. Each machine frame part is adapted to be secured separately on the machine base.

Abstract: A rotary cutting device for material webs consists of a machine frame with rollers supported in pivot bearings on the machine frame, driven by rotary drives and defining a cutting range, namely a cutting roller and a counter cutting roller, which form a roller gap for feeding the web material between them within the cutting range. The cutting and counter cutting rollers are supported so as to roll directly one over the other using spacing rings located outside the cutting range. At least one of these rollers engages at least one adjustable pressure roller link bar between the spacing rings so that the link bar presses one roller against the other roller with an adjustable force.
