Definitions

  • ABSTRACT An apparatus for winding paper or the like onto two shafts driven by a rotating cylinder which they contact at diametrically opposite locations.
  • the shafts are urged at their ends toward and into contact with the cylinder.
  • a pair of rollers rotatably mounted on a frame articulated to a pivot arm urge said shaft toward the cylinder to make certain of uniform contact along the length of the shaft so as to prevent bowing and wrinkling.
  • the pivotal mounting of. the arm permits displacement as the package builds up. After the package is large enough so that the paper reinforces the shaft and itself ensures uniform contact without bowing, the pivot arm is moved to inoperative position where the rollers no longer act on the shaft.
  • the invention relates to a method and apparatus for winding material in web form, such as paper or the like, by means of two winding shafts located on diametrically opposite sides of a supporting cylinder.
  • the undesirable bending or sagging is caused by the fact that the wound roll is supported at the ends of its shaft i.e., there are no intermediate supporting means and thus the roll is wound substantially without any support from below.
  • a force acting in the direction of the supporting cylinder is applied to the end supports of the roll being wound, thereby urging the roll against this cylinder, and in this manner it is supposed to be subjected to a uniform linear pressure. Since the roll being wound is still very flexible in its initial stages, however, the axial pressure cannot be distributed uniformly over the entire width of the roll being wound, so that the terminal portions of the roll are subjected to greater pressure than its central portion. This results in a deformation or bowing of the roll under the contact pressure corresponding to the line of curvature of a cylinder being stressed at each end with a point load.
  • The'invention is addressed to the problem of winding rolls having a uniform tightness all along their width.
  • the roll being wound is provided in its initial stage with such inherent stability that the winding process can thereafter be completed without auxiliary supporting means while achieving a' uniform tightness.
  • the winding process which is started under simultaneous, radially directed pressure at the ends of the winding shaft as well as intermediate the ends, is completed under complete freedom of pressure intermediate the shaft ends after a certain roll diameter has been reached, and the remaining axial pressure on the ends of the shaft of the roll being wound is varied in accordance with its diameter.
  • a pair of pressure rollers which supply the intermediate radial pressure on the circumference of the roll being wound are disposed on the free end of a lever which is itself mounted so as to be displaceable to inoperative position where it does not affect the movement of the roll.
  • the pivot point of the lever is located in such a manner that the force vectors of the individual pressure rollers intersect one another throughout the winding process in a plane determined by the supporting cylinder axis and the axis of the roll being wound.
  • FIG. 3 shows the pair of pressure rollers on a larger scale
  • FIG. 4 shows the manner of operation of the pair of pressure rollers.
  • FIG. 1 a web of material 1 is drawn from a supply roll 2 and fed over guide rolls 3, 4 and 5 through a longitudinal slitting means consisting of bottom knife 6 and top knife 7, to a driving support cylinder 8 from which I one of the longitudinal divisions of the web is delivered to winding station 9 and the other is delivered to winding station 10.
  • Winding cores l1 and 12, each of which respectively receives the strips 1' and 1" of the slit web 1" are received in carriages 13 and 14, respectively, and urged against the supporting cylinder 8 by a conventional lever system (not shown).
  • the corresponding pivot arms 17 and 18 are suspended in a pivotally displaceable manner about round guiding means 23 and 24.
  • the arrangement of the pivot arms or levers 17 and 18 is such that the pairs of pressure rollers 19-19 and 20-20 are able to follow the constantly growing diameter of the wound packages -26 within their range of action, with both pressure rollers bearing constantly against the circumference of the packages being wound.
  • the arms 17 and 1 8 with pressure roller pairs 19-19 and 20-20 are swung up out of-range about the round guiding means 23 and 24 which serve as their pivot point or fulcrum (by means of the phantom structure in FIGS. 1 and 2).
  • Rolls 25 and 26 then continue to be wound and are urged against the supporting cylinder 8 with an axial pressure that is constantly diminished by means of levers (notshown) as their diameter increases, until the final diameters 27 and 28 are achieved and the carriages 13 and 14 are in their outermost position on the guiding means 29 and 30.
  • levers notshown
  • the next winding cycle can be performed in the same manner.
  • an apparatus for winding of material in web form including a pair of winding shafts for receiving respective material to be wound thereon, a supporting cylinder contacting and driving said shafts, said shafts being diametrically opposite one another about said cylinder, and means urging the axes of said shafts adjacent their ends radially toward said cylinder, the improvement which comprises a pair of spaced pressure rollers urging each of said shafts intermediate its ends radially toward said cylinder, a pivot arm for each of said intermediate urging means, means coupling said intermediate urging means to said pivot arm, whereby as said material is wound upon each shaft and the diameter of said shaft and material thereon increases said intermediate urging means and pivot arm are pivotally displaced while still urging said shaft intermediate its ends, and means for displacing each of said pivot arms with its associated intermediate urging means to inoperative position wherein said intermediate urging no longer operates upon said shaft while material continues to be wound on said shaft, whereby the intermediate urging means may be rendered inoperative after said shaft has become stabilized due to receipt thereon of
