Definitions

  • the new or replacement web roll must be accelerated to a speed at which its surface velocity is the same as or very closely approaches the speed of the web running to the press from the expiring roll.
  • The'ieading edge of the new web roll must be removably fastened to the roll surface and must carry a strong and tacky adhesive, and the two webs must be pressed together after the proper new roll speed is attained and only at such point in the rotation of the new roll that the adhesivecarrying leading end of the new roll is approaching the surface of the running web.
  • the last mentioned condition is essential to prevent the partial sticking of the adhesive-bearing leading end of the new roll to the running web, whereby a loose adhesive-bearing flap would be carried into the press.
  • a cordance with the present invention to provide an improved and highly simplified method of splicing the web from a new roll to the web running at high speed from an expiring roll without the use of any auxiliary apparatus such as new roll speed-up means of the belt or spindle drive type or timed web pressing or severing means.
  • the invention also embraces an improved roll of web arranged formaking a splice according to my improved method,
  • the invention will be described in connection with a typical application thereof, namely, in the splicing or replacement of a paper web running into a printing press. It should be understood that the method and apparatus described is also applicable to the replacement of webs of fabric and other material and paper webs fed to mechanism other than printing presses.

  • Fig. 2 is a sectional view on a larger scale of the inner or core end and outer or leading end of ing the use of distinctively colored end portions;
  • Fig. 3 is a sectional view similar to Fig. 2 of a web with the leading end formed as a separate section attached to the main body portion of the web;
  • Fig. 4 isa sectional view similar to Fig. 2 showto the roll core
  • Fig. 5 is a perspective view of the web illustrat- Fig. 6 is a diagrammatic side elevation of a web roll reel and tension belts for use in practicing the invention in the position in which the web is running from one roll prior to the .time when rcplacement thereof by a new roll is required;
  • Fig. 7 is an elevation similar to Fig. 6 showing the reel in the position it occupies while the new web roll showing the arrangement of the tension belts.
  • a new paper web roll [2 of the type used to supply high speed printing presses and incorporating certain features of my invention is illustrated.
  • the leading or outer end l3 of the web on this roll is preferably removably secured to the roll surface by any suitable known means.
  • frangible gummed tabs l8 are used for this purpose, but a weak adhesive, sticking the leading end I3 to the surface of the next course of the web on the roll, may be substituted in accordance with known practice.
  • the opposite surfaces of the web on each new roll are prowhich adheres to the web when applied, and.
  • An adhesive suitable for the purpose described may comprise any one of a number of known non-vulcanizing rubber cements.
  • these cements comprise raw unvulcanized rubber, usually subjected to a small amount of hot milling, dissolved in a suitable solvent.
  • Solvents employed in such cements include gasoline, benzene, ethylene dichloride, carbon tetrachloride, varnish makers .and painters naphtha, and a special rubber solvent comprising a petroleum distillate having an initial boiling point of from about 120 to 180 F. and an end point of from about 250 to 288. F.
  • the amount of rubber in such cements runs up to 8% or 10%, and known solvent diluents such as isopropanol, ethanol, butanol, amyl acetate, butyl acetate, acetone, or
  • a layer It of self-sticking adhesive is applied across a relatively narrow area on the outer surface of the web at or adjacent its leading end l3. This adhesive is applied in fluid form and is thereafter dried, by
  • a similar layer I! of self-sticking adhesive is similarly applied to the web adjacent its inner or core end on the opposite surface thereof from that bearing the leading end layer I6.
  • the inner or core end layer I1 is on the inner surface' of the web.
  • the core end layer may be applied directly to the web 26 as shown at ii in Fig. 3, it is generally preferable that the adhesive layer I! be applied to a separate end section H which is later spliced to the web 26 bysuitable means such as a strong adhesive, as indicated at 20 in Fig. 2.
  • the tail end of the end section 19 is preferably left bare for a distance sumcient to permit the application of several uncoated courses 25 thereof to the core 2
  • the layer l1 of self-sticking adhesive is applied along a longitudinal section of the inner web, surface which is at least as long as the circumference of the finished roll l2. .
  • the roll circumference does not vary greatly in different rolls wound for use in the same presses,
  • the core end layer I! of self-sticking adhesive is applied to the web section l9 or the web 26 and dried thereon as explained above in connection with the leading (and adhesive layer I6. With the core end adhesive layer applied directly to the web or secured thereto on a separate end section, the web may be wound up on The paper web rolls used by newspaper and other presses are very large and heavy, and accordingly the central layers are subjected to considerable pressure from the weight ofthe overlying courses.
  • the adhesive repellent should be coextensivewith the adhesive layer laterally of the web and should extend beyond the adhesive layer toward the core end a distance at least as great as the circumference of the core 2
  • Figs. 6 through 10 The operation of splicing a web in accordance with the invention has been illustrated in Figs. 6 through 10.
  • I have illustrated a conventional three-roll reel at,3l.
  • the reel 3! which turns about a central axis 32, carries three spindles 33, 34 and 35.
  • the spindle 33 is shown carrying a roll 35 from which the running web 37 passes over an idler roller 38 and to the press or other web-consuming equipment; not shown.
  • New rails 39 and Ml are shown mounted respectively on the spindles 34 and 35. All of the rolls here illustrated have been prepared for splicing as described in detail above.
  • a set of tension belts tacts the running web, but since. as described above, this adhesive is dried to a point at which it does not adhere to the uncoated web surface. neither the acceleration of the new roll nor the normal running of the web 31 are impeded.
  • the reel 3! When it becomes necessary to replacethe web running from an expiring roll such as 36 with that from a new roll, the reel 3! is first rotated clockwise from the position shown in Fig 6 to that of Fig. 'l in which the cylindrical surface of the new roll 35 engages the surface cf the running web 31 and presses this'web between its surface and thebelts ll.
  • the rapidly moving web 31 quickly accelerates the new roll 38 to a speed such that its surface velocity equals or approximates the velocity of the running web 31.
  • the self-sticking adhesive layer l5 at the leading end of the web on the new roll repeatedly conspliced together, the leading end 13 of the web from the new roll is pulled away from the roll surface, the tabs 14 or other web and fastening means on the new roll being separated.
  • the new roll web then becomes the running web, and the reel 3
  • the brushes 50 if employed, may be retracted after the splice is made.
  • the line of perforations, or equivalent weakened portion 25 of the web or its core section runs off the expiring roll.
  • the pull of the web severs it along the perforations, as indicated at 52 in Fig. 9.
  • This web severance may be expedited by fastening the tail of the web to the core, as explained above and illustrated in Fig. 4. In this case, an increased tension is imposed on the web when it has run off to the point. that it is fixed to the core, whereupon the web breaks along the line of perforations 25.
  • severance along the weakened line may be expedited by imposing.
  • the old web may be severed 'after the splice by a knife 154 or other web-severing part in a known manner. 'This operation is llustrated in Fig. 10.
  • the knife 54 may be moved to cutting position after the splice is made, either by a manual operation or by known automatic means such as means responsive to the reduction in the diameter of the expiring roll to a predetermined point.
  • the method of the invention effectively splices the web from a new roll to the running web without any reduction in web speed and without the used of any special roll-accelerating means. This avoids the necessity of correlating the diameter ofeach new roll to the web speed and adjusting a spindle drive roll accelerating mechanism accordingly, and eliminates the use of speed-up belts movable into engagement with each new roll in turn.
  • a more important advantage of the invention is the fact that it wholly eliminates critically timed splicing operations. All that the operator has to do is turn the reel to move the new roll against the running web when the reduction in size of the rimning roll indicates that it is approaching its end. Thereafter the splicing operation is self-performed by the self-sticking adhesive layer arrangement, and no critically timed apparatus or adjuncts governed in accordance with the angular position of the new roll or otherwise are required.
  • the point in the running of the expiring web roll at which the splice is made is fixed when the roll ismade up and the economic consumption of the web is not dependent upon the judgment of the operator or any other variable factor.
