    The invention relates to a device for Bandfinishen with a first roll holder for a roll of tape, a second roll holder for an empty tube, a connected to an oscillating pressure roller and a drive for generating a tape feed of a withdrawn from the tape roll processing belt. The drive is in operative connection with the second roll holder. The withdrawn from the tape roll processing belt is guided around the pressure roller and wound by means of a rotary movement of the second roller holder on the empty tube.
    The described device for Bandfinishen can be used for superfinishing peripheral surfaces of wave-shaped or rotationally symmetrical workpieces. In this case, the workpiece is driven in rotation and superimposed on the rotation of the workpiece an oscillating movement of the tool surface formed by the tool band. The processing belt is mechanically worn at the contact point. By an intermittent or continuous tape feed the finish machining is always provided a non-worn tool surface. In contrast to belt grinding, the processing belt does not run continuously as an endless belt, but is pulled off from a belt roll and wound up on an empty tube. From time to time, a new roll of tape must be used and removed from the wound on the empty tube processing tape.
    A strip finishing device with the features described above is known from practice. In the known device, the roll holder are mounted on one side on a side surface of the housing of the device and are freely accessible on the housing side surface. The tape roll can be attached to a free shaft end of the roll holder and tensioned by means of a shaft end arranged turnbuckle against a fixedly connected to the shaft pulley. Accordingly, the arrangement and fixation of the empty tube is provided. At the rear of the housing side surface joins a housing space, are arranged in the bearing for the roller holder and cooperating with the drive gear parts.
    The workpieces to be processed often have a plurality of bearing surfaces, sealing surfaces and other peripheral surfaces which are to be processed by Bandfinishen. For production reasons, it is desirable to use several devices for Bandfinishen side by side for simultaneous finishing. In the known device is a parallel arrangement of several identical devices side by side only to a limited extent possible. By design, the housing of the device is much wider than the width of the processing belt. Furthermore, when changing a tape roll sufficient lateral clearance is required in order to deduct the tape roll and the empty tube from the roll holders can. The required distance between two parallel arranged Bandfinishgeräten is therefore a multiple of the width of the processing belt, which also represents the useful width of the device.
    Against this background, the present invention seeks to provide a device for Bandfinishen, which has a small width and allows a change of the processing belt in tight spaces.
    The invention and solution to this problem is a device for band finishing according to claim 1.
    The invention is based on a device for Bandfinishen with the features described above. According to the invention, the two roll holders are arranged in a cassette and exchangeable through an upper-side opening of the cassette. The roller holders each have a shaft mounted on both ends and a disk fixedly connected to the shaft for lateral delimitation of the wound-up processing belt. The shaft ends of the roller holders engage in lockable bearing recesses of the cassette. Further, the disc of the second roller holder on a sprocket, which is in engagement with a pinion driven by the drive. It is understood that between the pinion and the drive, a gear train and / or a chain drive can be provided for power transmission. The inventive device is designed as a cassette device. The tape roll can be inserted at the top of the cassette. Accordingly, the empty tube can be taken out with the wound-up processing tape at the top of the cassette. The disc of the second roller holder fulfills a dual function. On the one hand, the disc forms a stop surface for the processing tape wound up into a roll of tape. At the same time, the disc with a circumferentially arranged sprocket is part of a cooperating with the drive gear train and is supported by a pinion, which within the cassette, z. B. in the lower part of the cassette, is stored, directly driven. Due to the inventive design, the device for Bandfinishen is only slightly wider than the bandwidth of the processing belt. Furthermore, the device according to the invention requires no lateral free space for changing the roll of tape and the empty tube.
    The disc of the first roller holder preferably also has a ring gear, which is in engagement with a pinion of a braking device. By the braking device, the belt tension of the processing belt is adjustable and changeable. The roll holder for receiving a new roll of tape and for receiving an empty tube may be of identical construction.
    Between the shaft of the roll holder and an attachable to the shaft sleeve which forms an empty tube or the core of a roll of tape, a rotationally fixed connection must be made. According to a preferred embodiment of the invention, the shaft of the roller holder and the attachable to the shaft sleeve are rotatably connected by a radially acting anti-rotation. The rotation lock can work positively or non-positively. In the context of the invention, it is, for example, the shaft of the roll holder and the attachable sleeve with a complementary profile form, which allows a connector and causes a positive connection in the direction of rotation. According to a preferred embodiment of the invention, the shaft of the roller holder on the periphery projecting, flexible spreading for rotation of a plugged sleeve. This embodiment allows the use of sleeves with a cylindrical inner surface. A particularly effective anti-rotation device, which is effective in both directions of rotation, can be realized by means of a spring plate fastened to the shaft of the roller holder, which protrudes on both sides of the attachment point.
    The bearing recesses for the roll holder are arranged in side surfaces of the cassette and have at the edge of the cassette open insertion openings, which are each closed by a strap. The strap closure can be designed as a pivot closure.
    Preferably, the drive and the oscillation unit are arranged below the cassette. At this additional rollers can be stored.
    The pressure roller is mounted according to a preferred embodiment of the invention on a vibrating head, which is fixed to leaf springs and short-stroke oscillatory movements transversely to the web direction of the processing tape executes. The oscillatory movements can be generated electromagnetically or by an imbalance drive.
    The cassette, the oscillation drive and the drive for generating the tape feed form an assembly that can be arranged on a feed carriage. By a z. B. pneumatic feed movement of the feed carriage, the contact pressure of the processing belt can be adjusted and varied on the workpiece surface. The device according to the invention can also be used as a top-mounted machine for lathes. In the lathe, the workpieces to be machined are tensioned and driven in rotation during the belt finishing. The strip finishing device can be arranged as a self-contained unit on the tool carriage of such a machine tool.
