Definitions

  • ends of rolls have been fastened by glueing all across the end of the roll, or by manually applying a strip of adhesive tape over the end or by embossing the end with indentations, which penetrate several layers of paper to force the layers into intimate contact.
  • Glueing down the end of a roll, across the width of the roll is very inconvenient when it is desired to start unwinding the roll. It is often necessary to cut across the roll, which is wastefull and a suitable cutting is not always available.'Tearing results in much damaged material.
  • a strip of adhesive material is an expensive method as labour costs are high. Also, release of the tape is often difiicult.
  • the present invention provides a simple method of fastening the ends of rolls of material, the ends are easily unfastened as a tab portion is left free.
  • the attachment of the end to the remainder of the roll is only at one or more localized points and is therefore easily broken.
  • the application of the adhesive is at the same time as cutting of the material and no extra labour is required.
  • the invention is concerned With the application of one or more localized areas of adhesive to the end of a roll of material substantially simultaneously with the cutting of the material on finish of forming a roll.
  • the adhesive is applied a short distance from the cut end, and when the roll is completely wound the adhesive fastens down the end but leaves a short tab sticking up slightly. The end is thus easily and quickly unfastened when necessary.
  • Existing apparatus is easily adapted and no additional labour is required.
  • FIG. 1 is a cross-section through one embodiment, illustratrng a part of a bed-roll and the associated reciprocatmg knife blade and co-operating roll with cutting blade, and a reciprocating member for pressing the material against the glue applicator.
  • FIG. 2 is a diagrammatic illustration of a roll of material with the adhesive applied, and the end fastened
  • FIG. 3 is a cross-section, similar to FIG. 1, of an alternative embodiment, illustrating a different form of glue pp y,
  • FIG. 4 is a cross-section on the line 44 of FIG. 3.
  • the material indicated at 10 from the slitting, embossing and unwind stand, or some other similar apparatus, is fed to a bed-roll 11. From the bedroll, the material, after cutting, is fed to a rewind section, not shown.
  • the bed-roll 11 is hollow, and has a portion 12 cut from its peripheral circumference 13. Mounted in the cutout portion is a plate 14.
  • a shaft 15 is pivotally mounted within the bed-roll 11, the axis of the shaft parallel to the axis of rotation of the bed-roll.
  • the shaft 15 is positioned adjacent the periphery of the bed-roll and carries a knife-blade 16 and a back plate 17.
  • the knife-blade 16 and back plate 17 reciprocate, with shaft 15, to project through an opening 18 in the plate 14 positioned in the cut-out portion 12.
  • the shaft 15 is actuated by mechanism, not shown, so that the knife-blade 16 and back plate 17 extend through the opening at a predetermined rotational position of the bed-roll 11.
  • a further roll 20 Positioned adjacent to the outer periphery of the bedroll 11 is a further roll 20.
  • Roll 20 carries a further knifeblade 21.
  • the axis of the roll 20 is parallel to the axis of the bed-roll 11 and rotation of the roll 20 is synchronized so that the two knife-blades 16 and 20 co-operate to cut the material 10.
  • the back plate 17 holds the ends 22 of the material away from the peripheral surface of the bed-roll to facilitate the feeding of the end 22 onto the rewind section.
  • Knife-blade 16 and back plate 17 are mounted on the shaft 15 by a clamp 23 which permits of adjustment of the position of knife-blade 16, backing plate 17, so that the two knife-blades 16 and 21 co-operate correctly.
  • a lifter or presser bar 26 there is mounted on the shaft 15, by means of a further clamp 25, a lifter or presser bar 26.
  • the bar 26 has an arcuate surface 27 which, when the bar is extended through the opening 18, lifts the end of the material away from the surface of the bed-roll 11.
  • a glue applicator 30 Adjacent the peripheral surface of the bed-roll 11 is mounted a glue applicator 30.
  • the glue applicator comprises a stationary sleeve 31. Rotatably mounted on sleeve 31 is a sleeve 32 having an enlarged cylindrical portion 33. The portion 33 revolves through a reservoir 34 which holds molten glue. A metering blade 35 controls the thickness of the glue film on the portion 33.
  • the applicator 30 is mounted on a bar 36 extending across the machine and as many applicators as required are mounted on the bar.
  • the sleeve 32 is rotated at a slow speed by drive means, not shown.
  • an electric heater 37 Positioned within sleeve 31 is an electric heater 37 comprising a heater wire wound on a flexible mandrel.
  • the periphery of the cylindrical portion 33 is posttioned relative to the periphery of the bed-roll 11 so that,
  • the surface 27 of the bar 26 will press the material into contact with the portion 33.
  • a localized spot or area of glue is applied to the material 10. It will be seen that the glue will be applied a short distance from the cut end of the material for a purpose to be described.
  • FIG. 2 illustrates a roll of material, for example, a roll of toilet tissue, 40.
  • Two localized areas of glue, 41 and 42, are indicated. As described above, the glue is applied a short distance from the cut end of the paper; and a tab portion 43 is left, which sticks up from the surface of the roll. This provides a quick and easy way for starting the roll as the tab 43 can readily be gripped by the fingers.
  • the roll 40 is illustrated with two glue areas. This would require two glue applicators 30 positioned apart on bar 36, so as to apply the glue at the desired locations. If a single area of glue would sufiice, then this would probably be at the centre, and only a single applicator would be necessary.
  • the invention provides a very simple, easy and cheap way of securing or fastening the end of a roll of material.
  • the necessary apparatus can readily be attached to existing apparatus, avoiding expense of additional machinery. No additional labour is necessary.
  • the glue used can be of any suitable type, as long as it can be transferred by a roll or wheel, and have substantially instant tack.
  • FIG. 1 also illustrates a further feature.
  • Pivotally mounted within the bed-roll 11 is a further shaft 45.
  • the shaft 45 is adjacent the periphery of the bed-roll and its axis of rotation is parallel to the axis of the bed-roll.
  • the shaft 45 carries a carrier member 46, which is clamped to the shaft, and a rubber pad 47 is attached to the carrier member.
  • the shaft 45 is reciprocated in the same manner as shaft at a later rotational position of the roll 11, reciprocation of the. shaft causing the pad 47 to extend in a radial direction through the opening 18 to press the leading edge of material 10 against the core. Glue is applied to the core before winding.
  • Pins 48 are attached to the back plate 17 and project towards the roll 20.
  • a soft rubber foam pad 49 is attached to the periphery of the roll and the ends of the pins 47 enter the pad 49 and the end of the material is gripped and positively fed forward. The end of material will be pushed onto the pins and will remain on the pins until they are retracted beneath plate 14. This retraction does not occur until well past the cutting position and generaly the pins remain projecting until adjacent the rewind section and assist in feeding the material to this section.
  • FIG. 2- illustrates an alternative form of arrangement for the supply of glue.
  • the same reference numerals are applied for those items which are the same as in FIG.1.
  • the material 10 is fed to the hollow bed-roll 11.
  • the bed-roll 11 has a cut-out portion 12 in its circumference 13 within which is mounted plate 14.
  • Shaft 15 is pivotally mounted within the bed-roll 11, with its axis parallel to the axis of the bed-roll.
  • the shaft 15 carries a knife-blade 16 and a back plate 17, the knifeblade and back plate reciprocating, with reciprocation of shaft 15, to project through the opening 18 in the plate 14.
  • the presser bar 26 Also mounted on the shaft 15 by clamp is the presser bar 26, having an arcuate face 27.
  • Roll 20 Adjacent the outer periphery of the bed-roll 11 is a further roll 20.
  • Roll 20 carries the further knife-blade 2i, which knife-blade cooperates with knife-blade 16'.
  • FIG. 1 The major difference in the embodiment illustrated in FIGS. 3 and 4 is the apparatus for deliverying, or supplying, glue onto the material 10.
  • a glue applicator applies a spot of glue to the material 10.
  • the form of the applicator 59 will be more readily seen in FIG. 4.
  • the applicator comprises a housing 60 forming a cylindrical chamher 61 within which a piston 62 reciprocates.
  • Piston 62 comprises a metal body 63 with cup leathers 64 providing a pressure seal.
  • the cup leathers 64 are opposed as they are required to seal against pressures on both sides of the piston.
  • a spring 65 urges the piston to its retracted position, against a stop 66.
  • the main body of the applicator is in three parts, the housing 60 and two further hollow cylindrical members 67 and 68. This enables the insertion of the stop 66, which has a clearance from the interior wall of cylindrical member 69, for the flow of pressure fluid, as hereinafter described.
  • a flexible fluid pressure supply line 69 At the upper end of the applicator 60 is attached a flexible fluid pressure supply line 69.
