  • Patent number: 10532903
    Abstract: A winding device for a web-shaped material has at least one first frame and at least one first roller holding device, with at least one roller holding assembly which can rotate about a first rotational axis. The winding has device at least one pressing element, and the at least one pressing element is arranged to be movable relative to the first frame in at least one adjustment direction and opposite that at least one adjustment direction. The at least one adjustment direction has at least one component which points towards the first rotational axis. A guide system for at least one drawing device, for drawing at least one material web, is arranged such that a first guide section of the guide system is arranged in a stationary manner relative to the at least one first frame. At least one linear connection between the at least one pressing element and the first rotational axis always intersects a second guide section of the guide system, regardless of the position of the at least one pressing element.

  • Patent number: 8001899
    Abstract: A printing device, which is usable to produce printed products, is supplied with a material web of a predetermined length. The length of the required web is defined by the printed product to be produced. The material web is assembled from several partial webs, having defined lengths. The supply of these partial webs to the printing device is provided automatically with the use of a material management system. A control unit of this system determines the length for the partial webs that have been chosen for a certain production request. These partial webs are sent to the printing device in a certain sequence so that the last one of these partial webs to be used has the least web length of the several partial webs. The minimum length of the last partial web is determined by an end of the partial web finishing the production. This sequence is determined, at the earliest, after the cycle time has ended.

  • Patent number: 7832682
    Abstract: A material roll is transported to a roll changer by being arranged on a transport carriage. The material roll and transport carriage are placed on a transfer table which is moved into position between journal bearings of the roll changer. The transfer table is adapted to move the material roll transversely and along a longitudinal axis of the material roll and can pivot in a horizontal plane. An inclined position of the material roll, arranged on the transfer table, is determined by sensors. In this determined, axially aligned position, the material roll is axially aligned on the bearing journals. The roll size of the material is determined. An axially aligned position for roller support arms of a roll carrier of the roll changer is determined as a function of the determined roll size. An axially aligned position of the transfer table is determined as a function of the determined roll size and the determined inclined position of the material roll.

  • Patent number: 7784730
    Abstract: A device is provided for use in covering a danger area on a roll changer that can carry at least one roll of material to be directed to a rotary, web-fed printing press. A cover is provided with a drive that can move the cover. A control unit is provided to control the drive for the cover. The cover is closed in a first operational state and is open in a second operational state. The roll of material, that is supported by the roll changer, has a first rotational speed or web speed when the cover is in the first, closed operational state. In the second, cover opened, operational state, the roll of material also has a second rotational or web speed which is greater than zero. A method for controlling a device on a roll changer is also disclosed.

  • Patent number: 6111235
    Abstract: In a godet for advancing and guiding an advancing synthetic filament yarn, the bearing housing for supporting a shaft consists of an inner bearing support and an outer cooling body, which are in a heat conducting contact with each other. Cooling of a bearing within the bearing support is enhanced because the material of the cooling body has a coefficient of thermal conduction which is greater than the coefficient of thermal conduction of the bearing support material. In a heated godet, a cup-shaped godet casing fits over the end of the shaft, and a stationary hollow cylindrical support is fit over the shaft within the godet casing. An annular space is defined between the support and the shaft, and a heating element is mounted to the circumference of the support. The bearing housing at least partially defines openings that provide cooling air to the annular space.

  • Patent number: 4260113
    Abstract: Chips of scrap wood having a length at least twice the desired length of shavings for the making of particle board panels, as considered in the direction of grain, are fed into a rotor having an annulus of blades which split the chips in the direction of grain and feed the comminuted chips into the range of stationary comb-like knives serving to subdivide the split chips into shavings of ultimate length.
