  • Patent number: 4531930
    Abstract: In wound, preferably cylindrical paper containers, reinforcing rings of a synthetic plastic material are applied to the upper and possibly to the lower cut edges and joined by welding with the jacket. In order to insure that the core of the ring remains cold during welding and only the surface becomes liquid, thin-walled projections are provided in locations of the ring where welding is desired and are rendered flowable immediately prior to the placing of the ring on the jacket. Thus, the ring retains its structural integrity while being rendered weldable.

  • Patent number: 4531392
    Abstract: A method of controlling a rolling mill at high exit strip speed in which eccentricity of one or more of the roll assemblies causes undesired variations in the gauge of material exiting the mill. The method includes storing a model of the response of the load cells that measure the force at which the rolls of the mill engage the material in the mill, and a model of the response of actuator mechanisms of the mill that provide the force. In addition, the frequency of any eccentricity of one or more of the rolls during rotation. This frequency and the stored models are utilized to provide an estimate of possible phase errors caused by the lag in the response of the load cells in measuring the occurrence of cyclic changes in force due to eccentricity of the rolls and by the lag in the response of the actuator mechanism in moving to a particular position upon command from a controller.

  • Patent number: 4530694
    Abstract: To re-orient the position of a sheet, or package of sheets (3), for example after having been folded in a folding former, cut, and transversely folded in a folding knife cylinder, a pair of vertically aligned dish-like plates, or disks (4,5) are moved in an endless transport path. The plurality of such pairs of plates or disks may be provided, each pair being moved in a path by a gear belt (16, 29) driven by a gear or sprocket wheel (20, 30). The plates or disks receive a sheet, or package of sheets (3) therebetween, then are moved towards each other to clamp the sheet therebetween, for example under cam control (25) and a spring (24), and, when the sheets are clamped, additional rotation is supplied to one (4) of the plates or disks, the other (5) being freely rotatable, for example by a stepping motor (37) coupled thereto via a gear transmission and a bushing or sleeve concentric with the shaft driving the sprocket wheel.

  • Patent number: 4530227
    Abstract: In a hydrostatic support member a piston which is axially movable in a pressurized fluid medium-supplied cylinder carries at the end thereof which is remote from the cylinder at least two bearing shoes which are axially movable independently of each other and which can be inclined relative to each other. There is achieved an automatic adaptation of the bearing or running surface of the support member to a counter surface changing in distance, shape and curvature even throughout a wide tolerance range. Such a support member is particularly suited for supporting the working rolls in a rolling mill, the diameter of which decreases during the operating or service life thereof, or for the support of back-up or supporting rolls backing-up the working rolls.

  • Patent number: 4520614
    Abstract: Relatively tall stacks of paper sheets are introduced into successive cartons from above while the cartons are confined in the chamber of a receptacle whose side walls prevent excessive outward bulging of the adjacent side walls of the carton when a stack descends toward the carton in a vertical duct whose cross-sectional area is just sufficient to allow the stacks to descend. Each descending stack pushes a column of air into the carton wherein the air is compressed and urges the side walls of the carton against the respective side walls of the receptacle. The upper end of the duct receives stacks from an upright container having a bottom wall which is movable between open and closed positions. A side wall of the receptacle is detachable or otherwise movable to an open position so as to allow for insertion of empty cartons into or for removal of filled cartons from the chamber.

  • Patent number: 4519233
    Abstract: A rolling stand comprises a housing defining a pair of parallel and spaced inner axes and a pair of parallel and spaced outer axes flanking the inner axes and defining therewith a plane. Respective inner rolls are journaled in the housing at the inner axes and have bodies axially symmetrical about the respective axes and having centered on the respective axes roll-body surfaces of noncylindrical shape and each formed by rotation of a continuously curved generatrix about the respective axis. One of the inner rolls is displaceable axially relative to the other inner roll from an end position to another position. The inner-roll surfaces are spaced in the plane in the other position at a uniform distance and in the plane in the end position at a nonuniform distance. Respective outer rolls journaled in the housing at the outer axes bear toward each other on the respective inner rolls.

  • Patent number: 4515003
    Abstract: A method of shaping the gudgeon pin bores formed in gudgeon pin bosses of pistons comprises introducing into the bores portions of a pin-shaped tool before the insertion of the gudgeon pin. A load is applied to the pin-shaped tool and the direction of the load and the shape of the pin-shaped tool are chosen so that areas of bore-defining walls of the bosses subjected to high stresses by the gudgeon pin in use, and therefore liable to crack, are radially outwardly deformed to reduce the incidence of cracks.
