    Abstract: Several small diameter short width rolls (124) of plastic film (108) are wound from a larger width and length of plastic web in a continuous manner. The disclosed apparatus slits the larger width plastic web into several narrower width plastic webs, positions the slit webs on a single large diameter winding drum (110) and then winds each narrower width web at a separate winding turret (112, 114). At each turret, the plastic web is rolled around a first mandrel until the roll achieves the desired size. Then, a second mandrel contacts, the plastic web and the plastic web is severed between the first mandrel and second mandrel and attached to a second mandrel to be rolled into a roll of desired length. The process is repeated at each turret such that the several plastic webs are simultaneously wound in a continuous fashion.

    Abstract: Two cuts are made in the tire. Cut #1 is anywhere on the tire and cuts through the tread stopping at the bead. Cut #2 is placed 3? from Cut #1 and goes all the way through the tire cutting the bead creating the Tire Flap Lock, to be used to lock the tire in its final coiled shape. The tire is placed in a bin and the Tire Coiling Fork is pushed through the tire and begins coiling. The Tire Flap Lock is caught by the Tire Flap Prong and is held stationery while the tire continues to coil. As the tire completes its coiling the Tire Flap Lock is positioned around the tire so that when the Tire Coiling Fork is withdrawn the pressure for the tire to uncoil will be caught by the Tire Flap Lock thereby locking the tire in its new coiled shape as a Tire Building Block.

    Abstract: The invention relates to a cutting assembly for use in thin and ultrathin web winding stations. It also relates to a method for cutting a web using this cutting assembly. According to the invention, the web (1) is cut by a blade (30) with a cutting edge transverse to the web transfer direction; the blade moves between a rearward position and a forward position; in the forward position, the cutting edge is substantially parallel to an axis of the roll (7) receiving the web, and the blade is substantially tangent to a surface of the roll. For cutting the web, the blade is moved from its rearward position to its forward position, so that its speed at the time it engages with said web is at least substantially equal to the speed of the web. This ensures a clean and clear cut of the web. At the same time, it ensures that the leading edge of the web is smoothly and evenly placed on the roll, without any creasing nor folding of the web.

  • Patent number: 6450437
    Abstract: A reel configuration for winding thinly rolled finished strip after passing through a cooling section situated at the end of an installation for the continuous rolling of hot strip cross sections from thin slabs which are cast with near-final dimensions, on one of two expandable reel mandrels arranged such that they float in a horizontal and parallel manner with respect to one another. The mandrels are mounted such that they are rotatably driven independently of one another in a supporting structure which can rotate about a common horizontal center axis and to which the finished strip coming from the finishing train can be fed by means of a driver-shear combination. High speed emergency shears are arranged upstream of the driver-shear combination and have assigned to them a collecting space underneath the plane of the roller table for receiving the residual material from the finishing train.

  • Patent number: 6237870
    Abstract: A cutting device and a wedge shaped separating member are used to cut a packaging material wrapped around an outer perimeter surface of a web roll. The separating member is inserted under the packaging material. A cutting blade is fixed above the separating member to provide for the cutting of the packaging material when the cutting device and separating member are moved along a lateral axis of the web roll. The cut packaging material is completely separated by a second cutting device. The separated packaging material is then rolled and compacted. The result is an automated device which saves time and labor when removing packaging material from a web roll. Furthermore, the removed packaging material is compact, providing for reduced storage and disposal space.

  • Patent number: 6227088
    Abstract: An apparatus for the opening of paper bobbins and other rolls of material is provided. A flat blade is advanced from the side of a wound roll of material such that it intersects the roll over substantially its entire width. A cutting blade or other cutting mechanism then severs the layers of the roll which are outside the flat blade, and the flat blade protects the inside layers from being damaged. In preferred embodiments, a jet of air or other gas may be used to ease the insertion of the flat blade, or a gripping device which pinches the surface of the roll between opposed friction pads creates an arch in the surface of the roll through which the blade is inserted. The device is particularly suitable for use in cigarette making machines which require undamaged paper feeds.

  • Patent number: 6145777
    Abstract: A tail gap winder transfers a web from a first core to a second core by, immediately after the web is cut, pivoting the idler roller to lengthen the distance between the idler roller and the rotating drum to create a gap between the cut ends of the web; removing the first core from the rotating drum surface as the gap passes under the first core location; moving the second core into contact with the rotating drum surface; and winding the incoming cut edge around the second core. The idler roller pivots toward the rotating drum to decrease the distance between the idler roller and rotating drum and to take up the extra length of web during the winding portion of the operating cycle.

The carriages include a primary carriage which is moveable vertically with respect to the turret and a lay-on roll carriage which is moveable horizontally with respect to the primary carriage. The lay-on roll carriage has an arm which is engaged by the turret during movement of the spindle between the above two positions so that arcuate movement of the spindle is translated to movement of the lay-on roll carriage in such a manner that the lay-on roll accurately follows the movement as the building roll moves to the winding completion station.

  • Patent number: 5839689
    Abstract: An air box for use beneath a pair of carrier rolls or a roll winder for a web. The air box disposed beneath the carrier rolls has first and second side walls generally sealed respectively at each of the carrier rolls. The paper web passes beneath one of the carrier rolls and up between the rolls. The web may tear and the paper web then drops into the air box. A connecting wall in the air box between the side walls thereof and above the base receives the paper falling thereon rather than the paper falling into the air box. The connecting wall may be inclined to direct the falling paper toward a side wall where an opening is provided enabling the moving of the paper. The connecting wall may be perforated and the air flow into the air box is beneath the perforated wall so that the air flow through the wall cooperates in moving the falling paper along the connecting wall. As a result, the waste paper can be removed quickly and easily.
