Abstract: The invention relates to a device for receiving, transporting onwards and unwinding coils of rolled strip (WB) which are successively transported to the device from a strip rolling mill or a rolled strip storage unit. The device consists of a carousel-type support (KT) which can be driven in rotation about a vertical axis (VA) and on which a pair of radially projecting, rotationally mounted support mandrels (TD) with axial locking elements are located, these support mandrels being angularly offset from each other about 190°. The carousel support (KT) pivots the support mandrels out of a receiving position (A) for the coils of rolled strip (WB), into an unwinding position (C), about a pivot angle of 180°. The carousel support also has at least two other support mandrels (TD II and TD IV) which are offset from the two aforementioned support mandrels (TD I and TD III) by 90°, respectively.

Abstract: The present invention refers to a device for locking the descent of the reel-holder trolley along a sliding guide under the control of a traction belt in a fixed column winding apparatus. The device comprises a clamp of connection between belt and trolley, that is attached to the belt and is mobile in respect to the trolley between a first raised position in which the clamp is held by the upward traction exerted by the belt and holds in turn a pair of levers in such a position as not to interfere with side walls of the sliding guide of the trolley and a second position in which it moves automatically by gravity in the event the traction of the belt is released and in which it permits said pair of levers to be elastically stressed in such a position to enter transversally openings of the side walls of the sliding guide of the trolley to lock the descent of the latter.

Abstract: A paper web feeder is provided, which allows easy operations of maintenance and replacement to be achieved on occurrence of a malfunction. In addition, even if the number of wires is increased and connection means is up-sized due to expanded functions of support arms, no influence is given to bearings in support frames for a rotary shaft. A paper web feeder (A) for a rotary press comprises a pair of support frames (16, 17) opposing to each other. A rotary shaft (1) is rotatably supported by the pair of support frames (16, 17). Support arms (3, 4) are provided in plural and radial about the rotary shaft (1) for supporting a paper web (Q1, Q2, Q3) rotatably at each arm tip and configured to rotate integrally with the rotary shaft (1). Rotary conduction means (B) is located at a displaceable angle associated with rotation of the rotary shaft (1) for conducting to an electric device. The electric device displaces in angle associated with rotation of the rotary shaft (1).

Abstract: An improved web material dispenser that is designed to dispense web material, such as toilet tissue or the like. The dispenser is able to retain a roll containing tissue at a dispensing position until the tissue has been exhausted from the roll. The dispenser senses that the tissue is exhausted from the roll, and only then permits a reserve roll to be rotated into a dispensing position. Thus, the dispenser ensures that the tissue from each roll is used up before permitting access to a reserve roll. The invention also provides a new web material roll that utilizes a “double core”, as well as a method of making the “double core”.

Abstract: A paper roll driving apparatus for use in a paper roll feeding apparatus comprises a prime mover moving mechanism being freely reciprocally movable along a guide rail and having a moving body on which a prime mover is mounted, and a driving transmission mechanism comprising a relay shaft provided on the moving body so as to be in parallel to the rotating shaft and rotatable, an arm mounted on the moving body so as to be pivotable around the axial center of the relay shaft and driven by the prime mover at least via the relay shaft, and a driving transmission mechanism having a pivoting means for pivoting the arm at a predetermined angle; wherein both the prime mover and the driving transmission mechanism being adapted so as to be integrally movable with respect to the paper roll support in parallel with the rotating shaft.

Abstract: A rotary beam has mounted thereon a pair of carrier arms for rotatably supporting a roll of web from which the web is fed into the press, and another such arm pair for supporting another such web roll to which the web is to be spliced upon consumption of the first web roll. One of each pair of carrier arms has rotatably mounted thereto a hollow spindle to be partly inserted in the tubular core of the web roll. The hollow spindle has detents arranged at circumferential spacings thereon for fluid pressure actuation into frictional engagement with the inside surface of the web roll core. The other of each carrier arm pair has a second spindle rotatably mounted thereto which is to be held endwise against the web roll core via a spring-loaded end cap. How hard the web roll core is urged against the first spindle by the second spindle, resisting the unwinding of the web therefrom, depends upon whether the second spindle is held fast against the end cap or spaced therefrom by the spring.

Abstract: A wire uncoiler for holding coils of wire on mandrels for uncoiling and drawing by a downstream wire drawing machine. The movable restraining arm of each mandrel is biased by a spring mechanism to control wire payoff to the downstream drawing machine. The spring mechanism can be manually adjusted by a crank handle to control the tension in the spring and therefore the amount of restraining force applied by the restraining arm. The manual adjustment can be done while the wire drawing machine is actively drawing wire from the mandrel.

Abstract: Apparatus for introducing fresh bobbins containing supplies of convoluted web material into and for evacuating expired bobbins from web consuming machines has a reservoir for a horizontal row of coaxial fresh bobbins and a conveyor system for delivery of selected fresh bobbins directly to one of several stub shafts on a turntable which is indexible about a horizontal axis parallel to the common axis of the fresh bobbins in the reservoir. The conveying system includes an elevator which is movable into the reservoir from below to engage and lift a selected fresh bobbin and to thereupon transport it directly onto the selected stub shaft. An expired bobbin, normally in the form of a hollow core, is engaged by a gripper which moves it off the respective stub shaft and into a magazine which is adjacent and parallel to the reservoir.
