Definitions

  • the present invention relates to packaging thin webs in long lengths, and particularly to packaging long lengths of X-ray film in a light-tight envelope.
  • An example of such packaged webs with which the present invention is concerned is a commercially available industrial X-ray film wherein a long length of X-ray film is contained within a paper envelope opaque to actinic light.
  • the paper envelope comprises two strips of paper bound together at their longitudinal edges and having the strip of X-ray film interleaved between them but generally free to move longitudinally of the envelope.
  • Such industrial X-ray films after packaging, are normally coiled upon a core for convenience of subsequent handling.
  • the inside surface of the X-ray film extends over a path of shorter distance than that of the outside surface of the film, due to the difference in diameter of the two surfaces when on the coil. This gives rise to cockling a wrinkling of the X-ray film or other inner packaged web material.
  • the cockling is not particularly disadvantageous, but where the web to be packaged is a light-sensitive material such as X-ray film this is not the case.
  • the cockling due to the pressure sensitive nature of the X-ray film and/ or to the mechanical or chemical action, causes areas of fog to appear upon the film which upon processing of the latter, and these areas of fog may cause ditficulty in interpretation by the radiographer.
  • intensifying screens are normally bonded to the material with which the X-ray film is packaged, and in consequence, should this material cockle, the intensifying screen itself cockles and does not lie, at the cockle, a uniform distance from the X-ray film. This also gives rise to results which after processing, of the X-ray film, tend to render the task of the radiographer more difficult.
  • a web packaging apparatus comprising first and second packaging material supply means, supply means for the Web to be packaged, an arcuate plate, guide means for passing webs of the first and second packaging material with the web to be packaged therebetween over the arcuate plate and means for applying a sealant to the longitudinal edges of the webs of the first and second packaging materials to cause them to adhere while conforming to the radius of the arcuate plate, and take-up 3,458,965 Patented Aug. 5, 1969 means for coiling the packaged web in the same direction as the curvature of the arcuate plate.
  • support means he provided for supporting supply spindles for rolls of the first and second packaging materials and for a roll of the web to be packaged, the support means supporting spindles in vertical axial alignment.
  • Guide means may be provided between the support means and the arcuate plate for bringing the first and second packaging materials and the web to be packaged into contact with the plate in sequence.
  • the means for applying a sealant may comprise an adhesive tape dispenser at each side of the web and, if necessary, heating means for heating the sealant prior to applying the same to the edges of the sandwiched webs.
  • a plough may be provided adjacent each side of the web for inverting a portion of the tape so that the latter is pressed onto both the upper and the lower surfaces of the edges of the sandwiched webs.
  • Pressure pads may be provided immediately subsequent to the station whereat the sealant is applied to the webs, in order to compress the sealant and the webs together along the edges, to provide a more effective bond.
  • Edge guides conforming in curvature to that of the arcuate plate may be provided subsequent to the sealant applying station whereby the sandwiched webs are held in conformity to the curvature of the arcuate plate until the sealant has formed a firm bond. That edge of the arcuate plate whereover the packaged web passes to the take-up means may be so shaped as to iron-out any minor cockles occurring in the packaged web.
  • the means for applying the sealant, the ploughs (if provided), and the edge guides may be adjustable transversely of the arcuate plate so as to accommodate different widths of Web packages.
  • the web package take-up means comprises an expansible hub positionable on a driven take-up spindle and rotatable therewith and arranged to receive a take-up core thereover, the hub being contractible to permit removal and replacement of cores thereon.
  • the expansible hub comprise end pivoted bars extending parallel to the spindle and defining a cylindrical surface, each of the bars, at one end, being connected by a toggle linkage to a sliding spindle member, movement of the spindle member axially of the spindle, serving to move the respective ends of the pivoted bars radially inwardly or outwardly whereby to expand or contract the hub.
  • the invention also provides a method of packaging a web of material comprising the steps of feeding the web between first and second packaging material webs over an arcuate surface and applying a sealant longitudinally of the edges of the surfaces while the sandwiched webs are on the arcuate surface.
  • the sealant is preferably heated before being applied to the edges of the Webs.
  • the sandwiched webs may be guided in conformity with the arcuate surface, subsequent to the application of the sealant for a sufiicient period of time to permit the sealant to form a satisfactory bond between the edges of the webs.
  • the sandwiched and packaged web material may be fed from the arcuate surface over an edge providing a relatively abrupt change in curvature to a take-up roll whereby to iron-out any minor cockles in the web package.

  • an apparatus for packaging a web of material for example, X-ray film, which web is of considerable length relative to its width, and which web also is to be coiled after packaging.
  • the apparatus comprises a web support means 10, having two upright stanchions 11 providing bearings 12, for three spindles 13.
  • the spindles are one above the other in substantial axial alignment and the upper spindle supports a coil of a first packaging material 14; the second spindle supports a coil of the web 15 of the material to be packaged; and the lower spindle supports a coil of a second packaging material 16.
  • first and second packaging coils 14 and 16 will be of the same material and, in the particular use envisaged, may well each comprise a heavy grade of a lighttight paper, incorporating therewith an intensifying screen; the web 15 to be packaged, in the particular use, comprises X-ray film.
  • the first packaging material 14 is fed from the coil thereof under a guide roller 17 and onto an arcuate plate 18.
  • the web 15 to be packaged is fed under a guide roll 19 to the arcuate plate 18 and the second packaging material 16 is fed directly from the coil thereof to the arcuate plate 18.
  • a bar 20 engages the outer surface of the first packaging material to urge the packaging webs, and the interleaved web of material to be packaged, into engagement with the arcuate plate 18 at the commencement of their travel, as a sandwich, over the plate.
  • Mounted upon the arcuate plate 18 are two adhesive tape dispensers 21, one at each side of the plate 18 and each arranged to feed tape 22 over a respective heating block 23 into contact with the upper surface of the first packaging material 14.
  • the tape dispensers 21 are mounted on respective supports 24 which are adjustable transversely of the arcuate plate, i.e., parallel to the axis of the arcuate surface, and they are arranged so that tape 22 dispensed therefrom engages the upper surface of the first packaging material 14 by approximately half the width of the tape.
  • a plough 25, see FIGS. 7-11, is provided at each side of the arcuate plate 18, immediately subsequent to the station whereat the tape is applied to the packaging material, and serves to invert the free edge of the tape, so as to cause same to engage with and bond to the under surface of the second packaging material 16 as the webs move along the surface of the plate 18 as illustrated in FIG- URES 8 to 11.
  • Pressure pads may be provided adjacent the ploughs for urging the tape 22 into contact with the upper surface of the first packaging material 14 to cause a firm bond therewith.
  • One of these pressure pads is shown dotted at 100 in FIG. 7 so as not to obscure the showing of the plough 25.
  • an edge guide 27 for edge guiding and maintaining the sandwiched webs, with the tape bonded thereto, in conformity with the curvature of the arcuate plate 18 for a sufiicient period of time to enable adhesive of the tape to set.
  • mounting holes 26 are provided for mounting the edge guides and the ploughs 25 at various locations transversely of the plate 18 to accommodate different widths of web packages.
  • means, not shown, can be provided in the arcuate guide plate 18 for adjusting the position of the edge guides 27 and pressure pads 1130 to accommodate different widths of web packages.
  • the trailing edge 28 of the plate 18 is so formed as to provide a relatively small radius curve as the packaged material leaves the arcuate plate and, in so doing, serves to iron-out any minor cockles which may be present in the packaging materials or the tapes.
  • the take-u core 29 may be of cardboard or like material and is supported upon a take-up spindle 30 by means of an expansible and contractible hub 31.
  • the hub 31 comprises a first end plate 32 whereto one end of each of a plurality of bars 33 is pivotally attached.
  • a spindle member 34 is slidable axially of the spindle 30 and has pivotally secured thereto radially extending links 35 to the free ends of which are pivotally attached the free ends of the bars 33. It will be appreciated that movement of the spindle member 34 axially of the spindle 30 causes radially inward and outward movement of the ends of the bars 33.
  • a step 36 is provided on the spindle 30 such that movement of the spindle member towards the stop constitutes expansion of the radius of a cylinder defined by the bars 33, to an over-center position.
  • a cardboard or like take-up core 29 is positioned on the bars 33 while the spindle member 34 is in a position remote from the stop 36. Thereafter, the spindle member is moved towards the stop 36, causing the bars 33 to move radially outwardly to engage the inner surface of the core 29, to its over-center position in engagement with the stop 36.
  • the three rods 40 spaced 120 apart, serve to support the cardboard take-up core when the bars 33 are moved inwardly to their core disengaging positions.
  • the spindle 30 is driven by a motor (not shown) so as to provide for a peripheral speed of the core 29 and hence a linear speed of the web package, of the order of to feet per minute. At this speed, visual inspection of the packaged material is possible even under safelight conditions. However, with other inspection arrangements, it is possible to inspect the web at a linear speed of 300 feet per minute. To this end the motor may be a variable speed motor.
  • the heaters 23 are preferably retractable, so as, on stopping of the apparatus, they may be withdrawn from the tape feed path to prevent overheating of the tape and consequent loss of effectiveness of the tape in the bonding of the webs together.
  • the apparatus described may be used for packaging material other than X-ray film, which material i in web form and which material is to be coiled subsequent to packaging.
  • a sealant other than an adhesive tape may be used for bonding the two edges of the packaged material together.
  • the two webs of packaging material 14 and 16 could be slightly wider than the web interleaved therebetween and their adjacent faces could be joined by a pressure sensitive or heat sensitive coating applied to one or both thereof.
  • the two rolls of packaging materials need not be identical and, in the particular example given, each may or may not incorporate an intensifying screen.
  • the support means and the arcuate plate In its use in packaging a light-sensitive material, it may be advantageous to provide the support means and the arcuate plate with a light-tight housing, the take-up core being provided externally of the housing thereby facilitating visual inspection of the package before coiling.
  • a web packaging apparatus comprising means for supplying a strip of web material and first and second strips of packaging material each having a width at least equal to that of the Web material;
