Definitions

  • the web diverting device comprises a pair of facing surfaces which diverge from each other in the web feeding direction whereby each defines a respective one of the two alternative paths.
  • Air feed devices are arranged to direct a flow of air over either one of said surfaces as selected in the direction of web feed, to draw the web to that surface.
  • This invention relates to web feeding apparatus and has particular, but not exclusive, application to the feeding of paper webs to winding devices for winding the webs into rolls.
  • One intended application of the invention is in winding machines for winding wallpaper into standard length rolls for supply to the retail trade.
  • the wallpaper is usually fed as a continuous web to such machines from a large reel and in its feed is severed to form the tail end of one roll and the'leading free end of the next roll.
  • the winding machine has a single winding head it is necessary to provide a hold" system for the leading end of the next roll until the winding head is ready to receive it following completion and removal of the preceding roll. This results in a build up of web in the hold" system which has to be eliminated by high acceleration of the winding head at the start of the next winding operation. The high acceleration can lead to damage or breaking of heavy embossed wallpaper and webs of low tensile strength.
  • two winding heads can be used so that at the end of a winding operation on one head the leading free end for the nextroll is diverted to the other winding headto provide in effect an uninterrupted winding operation.
  • considerable difficulties have been encountered in diverting the leading end of the web for the next roll after the severing operation.
  • Attempts have been made to use mechanical fingers and suction rollers for changing the direction of the web. Problems arise in the use of fingers because there is no gap between the severed ends of the web through which fingers can be inserted and it is undesirable to create a gap by removing a transverse strip from the web.
  • suction rollers leads to difficulties in removing the web from the'rollers after it has been diverted and problems arise from windage created by the suction rollers having to rotate at high speeds.
  • the object of this invention is to provide web feeding apparatus including a web diverting device which does not suffer from the aforesaid disadvantages.
  • web feeding apparatus including a web diverting device which is controllable to cause a free leading end of a web to take a selected one of two alternative paths, the web diverting device comprising a pair of facing surfaces which diverge from each other in the web feeding direction whereby each defines a respective one of the two alternative paths, and means for directing a flow of air over either one of said surfaces as selected whereby the free leading end of a web passing between the facing surfaces is drawn to the one over which the flow of air is directed.
  • the flow of air provides lubrication between the surfaces and the web and constrains the web to follow the contour-of the plate surfaces.
  • the web severing means may operate by passing through the diverting device or the latter may be positioned between severing means and the winding heads.
  • the winding machine has two winding heads 1 and 2 of well known construction.
  • the web 40 is fed into the machine overa guide plate 3, then over guide rollers 4 and 5, through nip rollers 6 and 7 and thence through the diverting device 9 to one or other of the winding heads 1 and 2 as will be described.
  • the diverting device 9 comprises two facing plates 10 and 11 which extend parallel to each other for a length and are then curved to diverge from each other in the direction of web feed.
  • the plate 10 defines the web feed path to the winding head 1
  • the plate 11 defines the web feed path to the winding head 2.
  • respective air feed devices 12 and 13 which are located in gaps in the parallel portions of the plates 10 and 11 and have orifices 14 through which air is fed, the orifices being directed so that the air from device 12 flows downwardly over the surface of plate 10 and the air from device 13 flows downwardly over the surface of plate 11 as shown by the arrows.
  • a plate 15 of inverted V form is disposed below the plates 10 and 11.
  • One arm 16 of the V converges towards the plate 10 to define with the plate 10 a narrowing guide throat 17 leading to the winding head 1.
  • the other arm 18 of the V similarly defines with the plate 11 a narrowing guide throat 19 leading to the winding head 2.
  • Severing means in the form of blades 20 and 21 are disposed to pass through transverse gaps in the plates 10 and 11 respectively, at the position where the plates 10 and 11 commence to diverge, to sever the web 40 transversely.
  • the blades 20 and 21 are pneumatically operated through double acting air cylinders 22 and 23 and in their forward projecting position after severing the web, as shown for the blade 20, form a gate closing the adjacent guide throat.
  • Control means shown diagrammatically by control box 24 in the drawing are arranged to control the air flow from a pressurized supply to the air feed devices 12 and 13 and the air cylinders 22 and 23.
  • the control means comprises a valve arrangement made up of conventional valves and whose inter-relationship will be readily understood from the following description of the operation of the winding machine.
  • a signal is passed to the control box 24 from winding head 2 via line 29, to cause the air supply to be connected to air feed device 12 via line 28 so that there is a flow of air over the surface of plate and to be connected via line 30 to air cylinder 23 to cause operation of severing blade 21.
  • a signal is passed from winding head 1 via line 32 to the control box to cause the air supply to air feed device 12 and air cylinder 23 to be cut off.
  • Severing blade 21 is then retracted by an air supply on the other side of the piston. This is initiated through a timing device as described for air cylinder 22.
  • completion of the winding of the roll in winding head 1 causes a signal to be passed from winding head 1 to control box 24 via line 34 causing air to be fed to air feed device 13 and operation of severing blade 21 by air cylinder 21 resulting once again in the situation shown in the drawing.
  • the diverting device 9 has been found to work satisfactorily using an air pressure supply at about 10 to pounds per square inch, the rate of air flow over each plate 10, 11 being about 1 cubic foot per minute per inch across the plate surface.
  • the plates 10 and 11 are 24 inches wide and the air feed devices 12 and 13 extend across their full width, each air device 12, 13 would produce an air flow of 24 cubic feet per minute.
  • the orifice 14 which would extend as a strip across the width of its associated plate 10, 11, is of the order of .002 inches wide.
  • Web feeding apparatus including a web diverting device which is controllable to cause a free leading end of a web to take a selected one of two alternative paths, the web diverting device comprising a pair of facing surfaces which diverge from each other in the web feeding direction whereby each defines a respective one of the two alternative paths, the facing surfaces of the diverting device extending substantially parallel to each other for a length before they commence to diverge, and means for directing a flow of air over either one of said surfaces as selected in the direction of web feed, whereby the free leading end of a web passing between the facing surfaces is drawn to the one of the surfaces over which the flow of air is directed, the means for directing the flow of air over the facing surfaces comprising air feed devices respectively disposed in each of said facing surfaces part way along their substantially parallel portions, and web severing means positioned to sever the web substantially at the commencement of the divergence of said facing surfaces.
  • the web severing means comprise a pair of web severing blades, each arranged to be moved from an inoperative position behind a respective one of the facing surfaces to a position in which it projects through the facing surface to sever the web.
  • Web feeding apparatus wherein the diverging portions of said facing surfaces each define together with a further surface a web guiding throat and each of said blades in its projecting position closes the adjacent throat.
  • control means are provided for controlling the air feed devices and the web severing blades so that upon movement of one blade so that it projects through one of said facing surfaces to sever the web, the air feed device associated with the other surface is caused to supply a flow of air over said other surface.
