Definitions

  • the invention relates to improved method of and means for the surface coating of one side of reeled paper or similar material as unwound, from a supply reel or its equivalent to articles to be coated or to re-winding means.
  • the invention is particularly usein! in connection with the gumming of reeled paper, being fed to work-pieces such as cartons, cardboard boxes and the like on machines for lining and/or covering such containers.
  • the coating material may comprise substances other than glue.
  • fabric or cellulose materials can be employed instead of paper.
  • a glueing roller is mounted in bearing with its lower peripheral part immersed in the adhesive contained in a suitable reservoir, the strip material being lapped over the upper portion of the periphery of the roller.
  • the roller is revolved at an indeterminate speed by the strip material when pulled over it, picks up an indeterminate and widely varying amount of adhesive which is brought into contact with the paper surface. An excessive amount of adhesive is always applied which subsequently, has to be scraped off to get an evenly distributed film, involving considerable waste of adhesive,
  • Another known method is to mount in conjunction with the reservoir a positively driven slovv revolving glue feed roller, and to strip this, or pick up" adhesive therefrom, by a faster running second or' stripping roller also positively driven, but only intermittently, when the strip material is pulled through the apparatus over a portion of the periphery of the second roller.
  • This largely eliminates the defects of the first method described, but a considerable amount of mechanism is required, including a clutch, and further there is not exact relationship between the movement of the paper and the surface speed of the roller.
  • the coating film is now always 2 very thin, the evenness of the film cannot be satisfactorily maintained.
  • a method of surface coating web material consists in transferring the adhesive or other fluid coating material to the web of paper or the like tensioned for the purpose from a positively driven feed roller in contact with the adhesive material by means of an idler form of stripping roller with its periphcry out of contact with the feed roller, but sufficiently close to transfer the required quantity of coating material from the feed roller to the stripping roller, the stripping roller being rotated in unison with the varying speed of the web by the direct action of the arc of contact therewith of the said tensioned web.
  • a slow running driven feed roller dips into the coating material in a reservoir, and a light, balanced
  • This force is always sufiicient to reduce the inertia effects due to starting, or accelerating, the speed of rotation of this roller to a negligible amount, but is not sufiicient to interfere with the functional control of its motion, induced as now to be described.
  • the reel of material is suitably mounted and lightly braked to provide a constant small essential tension iifthe strip as it is unwound. Any convenient means, not forming any part of this invention may be adopted to provide this tension.
  • the web When the machine is in operation the web is so guided as to lap over a considerable are, approximately half of the peripherx of the stripping roller, and these guiding means are convenientlyprovided in such form that, when the machine is stopped for a period, the web can be removed from contact with the stripping roller to prevent it adhering thereto.
  • the invention provides a mechanically very simple method of attaining all these desirable results, for intermittent coating operations such as are required for instance in the case of box banding machines, together with simplicity and cleanliness of operation.
  • Figure 1 is a broken sectional and elevation showing the arrangement of feed and stripping 2 by reason of the slight spacing oi the peripheries of the rollers I and I, the roller I can be adapted to merely strip the surplus adhesive iluid from the feed roller I, and it is found in practice that if the roller I is left free to rotate idly on its bearings, without the .webv .II engaging it, the roller I is left free to rotate idly on its bearings, without the .webv .II engaging it, the
  • roller 8 will 'be' rotated simply by'r'eason of they influence of the coating of adhesive fluid of the positively driven roller I. In other words. the action of stripping the surplus fluid from the feed roller provides a continuous force always tending to revolve the stripping roller.
  • the web II is fed from a reel which is very lightly braked to provide a constant small but rollers, and the means for adjusting the paper or the like into engagement with, and away from.
  • Figure 2 is a broken plan view of Figure 1.
  • Figure 4 shows the paper moved away from the stripping roller.
  • the feed roller I is glue, this feed roller being mounted on a spindle I -joumalled at its ends in bearings in a frame part I of the coating machine and driven at a slow speed, e. g. forty R. P. M. from any suitable prime of the spindle.
  • a stripping roller 6 is provided slightly above the reservoir '2 parallel with the feed roller I, its
  • the feed roller I is adjustable towards and away from the roller I by mounting the spindle 3 of the roller I in bearing blocks II sliding in slots II' and receiving the threaded -ends of adjusting screws I2 held against axial displacement and having their unthreaded ends 'suitably fitted with adjusting knobs or screwdriver grooves in wellknown manner;
  • periphery of the stripping roller I is always slightly spaced from the periphery ot the feed roller I, the spacing being so adjustedthat the thickness of the film transferred tothe striprotated by the tractive eirort oi the web II, in
  • the web II is guided so as to lap over the periphery of stripping roller I through an appreciable are, which is nearly; approximately-mall of the periphery of-the stripping'roller, andsjor this purpose
  • the frame [carries a-pair pilike arms II pivoted at their lower ends to pivotpms I! fixed in the frame I and cranked between their ends to afford an arcuate corner II normally resting on the adjacent bearing pins IgI aforesaid.
  • These arms carry center-pins and II for a'horizontal pair of rollers or rotary rods II and 20 respectively over which the web I3 is drawn underften'sion.
  • v lltris preferred to provide at the free-ends of the arms II a relatively smaller roller- II to'guide the" "on II from the reel under the upper rollerre; of

  • Apparatus for the adhesive surface coating of a web material such as e. g. paper strip to be fed to workpieces to which the web material is to be adhered comprising a main frame, an idler form of stripping roller supported rotatably by said main frame, a positively driven feed roller supported rotatably by said main frame and driven independently of the stripping roller, a reservoir for the adhesive in which the feed roller is partly immersed, a web guide frame pivotally supported at one end and free at its other end, so that said guide frame can be lowered to an operative position where the web guided thereby will lay over the periphery of the stripping roller and can be swung upwards about its pivotal support to bring the web away from the stripping roller, two guides for the web material supported across the guide frame between its pivoted and free ends and, in the operative position of the frame, being disposed in a plane between the axis of the stripping roller and the axis of the feed roller and with the stripping roller spaced between them so that the web must engage
  • the said guide frame comprises a pair of arched arms across which are supported the said two guides and between which guides the stripping roller is located in spaced relationship when the guide frame is in the operative position, said arms being pivotally supported at one end on a common axis spaced from the stripping roller and disposed beneath the part of the periphery of the stripping roller contacted by the web, their other ends being free and disposed above the said pivotal axis, the said guides comprising a pair of guide rollers under which the web is drawn to cause the web to arch under tension over the stripp roller.
  • Apparatus according to claim 4 wherein an additional guide for the web is disposed across said arms between the free end of the guide frame and the adjacent one of said pair of guide rollers over which additional guide the coated web is drawn to afford a guide for the web when the guide frame has been swung away from the roller.
