  • Patent number: 5518199
    Abstract: An elongated support roller centered on and rotatable about a horizontal axis radially engages at least one row of takeup rolls coaxial to a takeup-roll axis parallel to the support-roller axis and including at least one central roll and a pair of end rolls axially flanking the central roll. A relatively wide paper web fed to the support roller passes through a slitter between the web supply and the support roller for slitting the web into a plurality of strips including at least one central strip and a pair of end strips flanking the end strip. The central and end strips pass at least partially around the support roller and are wound on the respective central and end rolls. The support roller is rotated about its axis so that the strips wind at least partially around the support roller and at least the central roll is rotated by engagement with the support roll. Respective end-roll periphery drives radially engage the end rolls for rotating same at a greater peripheral speed than the support roller.

  • Patent number: 4458853
    Abstract: An apparatus for the separate winding of slit webs onto at least two web rolls, comprising a pair of parallel driven rolls, a web roll bearing on each support roll at or in proximity to its uppermost generatrix, and an unloading means of adjustable force engaging the shaft of each web roll, whereby the winding force on each web can be varied as the diameter of its web roll increases.

  • Patent number: 4415128
    Abstract: In an apparatus for winding a web on a roll 7 supported by two driver rolls 1,2 and including a rider roll 8 bearing on the top of the web roll and mounted for vertical displacement in lateral guides 17, the improvement which comprises two further rider rolls 9 mounted on either side of the web roll and with their axes parallel thereto so that they make contact with the circumference of the web roll only after the latter has attained a predetermined diameter. A corresponding process is described.

  • Patent number: 4379012
    Abstract: There is provided an adhesive tape for the joining of webs, comprising a first tape provided on both its faces with adhesive, second and third cover tapes adhering to the faces of the first tape, and adhesive on the outside of the second cover tape, the adhesive on the outside of the second cover tape being stronger than the adhesive on its inside. The joinder is made by securing the outside face of the second cover tape to a carrier bar, removing the third cover tape, adhering the exposed face of the first tape to the tail end of a first web, removing the second cover tape with carrier bar attached from the first tape which continues to adhere to the web, and then adhering the freshly exposed face of the first tape to the head end of a second web.

  • Patent number: 4155515
    Abstract: A winding station for webs comprises a plurality of knives disposed side by side and which are laterally displaceable along the width of a web to predetermined positions for slitting the web into a plurality of narrower webs. A guide roller is disposed downstream of the knife and a plurality of pairs of winding frames are disposed in at least two rows in a staggered relationship on opposite sides of the guide roller. The winding frames are laterally displaceable into positions corresponding to the positions of the knives by means of servomotors. The winding frames bear projecting chucks for receiving winding spools thereon and gripper cones over the winding chucks which are expandable radially by axial displacement. A program control effects the positioning of the winding frames to align the gripper cones with the knives.

  • Patent number: 3944152
    Abstract: The application relates to an improvement in a rewinding machine for continuous individual webs of paper cut from a wider web, and including a backing cylinder, a plurality of winding shafts alternately arranged diametrically opposite one another relative to the backing cylinder, a roll on each of the winding shafts, and bearing blocks for each of the rolls, whereby the individual webs contact the backing cylinder and alternate individual webs are taken up on the rolls arranged on the winding shafts on each side of the backing cylinder, the bearing blocks permitting the shafts and rolls to move away from the backing cylinder as the roll diameters increase due to webs wound thereon, all known in the art.
