Definitions

  • ABSTRACT OF THE DISCLOSURE Apparatus for decurling a web as it is being fed from its supply roll including a frame having a pivotable decurl member mounted on a pivotable linkage and positioned in a web path and a rubber-covered roll operatively connected to the linkage and engaging the supply roll surface such that the angle said decurl member makes with the web path is caused to change to vary the degree of decurl in response to the changes in the roll diameter.
  • the decurl member comprises a generally circular member subtended by a chordal portion forming a decurling edge thereon.
  • This invention relates to an improved apparatus for decurling web material fed from a supply roll for feeding the web in flat condition free from curls and surface irregularities.
  • FIG. 1 is a generally side elevational view of a decurler apparatus according to the present invention
  • FIGS. 2 and 3 are exploded elevational views of the straightening member illustrating the angle of entry of the web at the beginning and end of supply roll feed, respectively;
  • FIG. 4 is a sectional view of the decurler apparatus taken along line 44 of FIG. 1 with parts broken away to show details therein;
  • FIG, 5 is a sectional view of the decurler apparatus taken along line 55 of FIG. 4 illustrating the apparatus in a position as it appears after the web has been fed out from its roll.
  • the invention is achieved by feeding a web from a supply roll through a path along which is positioned a straightening or decurl member which imparts a straightening action to the web depending on the angle of the web as the latter passes over or around the straightening member.
  • the straightening member is displaceable in coaction with a control member which is in contact with the web surface, such that the angle of the straightening member with the web is continuously changed to meet changing conditions in the curl of the web, i.e., the diameter of the roll.
  • the angle of entry of the web to the straightening member is such as to maintain the proper straightening action to the web which then is fed to any suitable utilization device such as a paper cutter for producing cut sheets for use in a copying/duplicating machine as described, for example, in copending application Ser. No. 664,474, filed Aug. 30, 1967. It should be understood that the decurler apparatus of the invention is not limited to copying/duplicating machines but may be used in other suitable machines as well.
  • a web of material W carried on a supply roll 10 is fed along a path around the lower surface of a straightening or decurl member 12 and over an edge 14 thereof at a predetermined angle to obtain a desired straightening effect on the web.
  • Straightening member 12 has a generally circular shape except for a small chordal portion at which edge 14 is formed. It will be noted that the degree of straightening imparted to the web depends upon the angle of entry of the web relative to the edge 14 of the straightening member. This angle at which web W is received by the straightening member changes and depends upon the position at which the straightening member deflects the Web path as shown by the solid and dashed line portions of FIG. 1 and also in FIGS. 2, 3 in a manner as will be explained more fully hereinafter.
  • the Web W After passing across the surface of the straightening member, the Web W is then fed around an idler roll 15 which redirects the Web path towards a web processing station P which may be in the form of a cutter mechanism or any other suitable utilization device.
  • a drag is imparted to the web by a follower roll assembly 16 which rides in contact with the surface of the web on the supply roll 10.
  • the follower roll assembly 16 is operatively associated with straightening member 12 to enhance the positiveness of the straightening action in a manner which will be explained more fully hereinafter.
  • the decurler apparatus not only straightens the curve of the web but also enables varying the decurling effect on the web as the need for this greater decurling effect is presented.
  • the apparatus comprises a frame 20 including a pair of leg members 22, 24 pivotable on pins 26 and 28, respectively, journaled in frame 20. Pins 26 and 28 are secured to frame 20 as by lock washers 32, 34, respectively.
  • another pair of leg members 36, 38 pivotable on pins 42, 44 are journaled in the frame and secured thereto by lock washers 46, 48 to form a parallelogram linkage.
  • a shaft 50 extends between spaced leg members 22, 24 and carries a pair of generally triangularly shaped plate members 52, 54 which are mounted at the free end of the leg members 22, 24 and serve to carry the follower roll assembly 16 and straightening member 12.
  • the follower roll assembly 16 comprises a cylindrical member 60 which is covered with layer 62 of friction material, such as rubber. Member 60' is closed at it's ends by cap members 64 and 66 which support the cylindrical member on an inner coaxially mounted roller 70 having shaft extensions 72, 74 which are received in leg members 36, 38, respectively, and are fixed thereto by lock washers 76 and 78.
  • a drag force is provided to the cylindrical member 60 through a coiled spring 80 pinned to extension 72 and engaging a washer member 82 which abuts a friction element 84 which is urged into contact with cap member 64 to apply a restraining force thereon.
  • a continuous drag is applied to the web material W by the follower roll assembly to ensure that the angle at which the web path contacts straightening member 12 is proper at all times.
  • decurl means mounted on said pivotable linkage means and positioned in the web path in contact therewith, said decurl means comprising a generally circular member subtended by a chordal portion forming a decurling edge thereon, and
  • said linkage means comprises a parallelogram arrangement of link References Cited UNITED STATES PATENTS 1,807,274 5/1931 Biedler 242-7545- 2,199,594 5/1940 Kent 242-7545 X 2,266,437 12/1941 Nelson 24275.45 3,081,014 3/1963 Anderson et a1.
