Definitions

  • the present invention relates to a method of producing a coreless roll of fibre-based, web-like material, in particular soft crepe paper or some other nonwoven material, for instance cleaning paper, kitchen paper, or toilet paper.
  • toilet paper rolls, kitchen paper rolls and cleaning paper rolls intended for large consumers are produced by winding a paper web onto a thin tubular core, normally a paperboard cylinder.
  • This paperboard cylinder or core naturally incurs an additional cost in the manufacture of the paper roll, and since it remains when all the paper has been used it must be thrown away.
  • Coreless paper rolls where the paper is taken from the centre of the rolls are known from SE-B-399,694, for instance.
  • the inner ⁇ most paper turns are secured to one another by means of water, optionally with a binder additive. This results in a stiffening core, formed by the innermost turns although these turns are not glued together directly, but can be unrolled with the remainder of the paper web and used in the same manner as the remainder of the paper.
  • the paper web is rolled onto an expandable wind- ing-on axle which is contracted so as to enable it to be removed easily from the paper roll carried by the axle at the end of a winding-on process.
  • SE-B-455,367 teaches a coreless toilet paper roll with which the paper can be taken from the periphery of the roll.
  • the winding-on axle used to produce the roll has a relatively small diameter, approximately 10-15 mm, and is of polygonal cross-sectional shape.
  • the centre hole that is formed when the paper web is rolled onto the axle and the axle removed, will present alternating, radially outwardly extending compressions and inwardly arched parts.
  • the winding-on axle is rigid, i.e. not expandable, although it can be removed easily from the paper roll, because of the small axle diameter.
  • the object of the present invention is to provide a simplified method for the manufacture of a coreless roll of material, for instance a paper roll, provided with a relatively large centre hole, and consequently the winding-on axle used must have a correspondingly large diameter. This accentuates the problem of removing the winding-on axle from the paper roll. This problem has been solved by means of the present invention.
  • the in-, ventive method is characterized by placing the leading end of the web around a non-expandable winding-on axle which has a fixed diameter of at least 35 mm and which is caused to rotate so as to wind the web onto the axle; applying a friction-reducing agent to the axle or to the first turn or turns of the web, with the intention of reducing friction between the web and the axle; and withdrawing the axle from the resultant roll, subsequent to termination of the web winding-on process.
  • Figure 1 is an end view of a centre-feed paper roll
  • Figures 2 and 3 illustrate schematically the initial stage of winding-on a paper web in accordance with two different methods
  • Figure 4 illustrates an alternative embodiment of a winding-on axle.
  • the paper roll 1 is produced by moving the free end 2a of a paper web 2 into engagement with a winding-on axle 3 in a winding-on machine.
  • the web is rolled up on a so- called carrying roller machine in which the winding-on axle 3 is mounted between a pair of rotatable carrying rollers 4.
  • Figure 3 illustrates a so-called centre drive system in which the actual winding-on axle is rotated. In both systems, as the axle 3 rotates paper is wound onto the axle and the axle is removed from the resultant paper roll upon completion of the winding-on process.
  • Paper rolls with which paper is taken from the centre of the roll require a relatively large centre opening, about 35-100 mm, which is governed by the other dimensions of the roll. Moreover, most paper rolls in- tended for taking the paper from the periphery of the roll are provided with centre holes with a diameter larger than 35 mm. Winding-on axles of corresponding dimensions are difficult to withdraw from the paper roll wound onto the axle. The friction between roll and axle is particularly great in the case of a fully cylindrical axle, since the abutment surface between paper and axle is then large. Slightly less friction is obtained with axles of a non-circular cross-section.
  • a fric- tion-reducing agent is applied to the axle immediately before or in conjunction with initiation of the winding- on process, with the intention of reducing the friction between the paper web and the axle.
  • This agent may consist of water, optionally with an addition of a softener, for instance quaternary amine, or other lubricant, such as silicone or the like.
  • the friction- reducing agent may alternatively consist of an oil, oil emulsion, triglyceride, teflon or the like.
  • the friction-reducing agent is applied to the axle 3 with the aid of a spray nozzle 4. It will be understood, however, that the agent can be applied in some other way, for instance it can be brushed onto the axle. Alternatively, the friction- reducing agent can be applied to the innermost turn or turns of the paper web 2 instead of to the axle 3, as illustrated in Figure 2.
  • Friction is reduced still further when the axle 3 is heated in conjunction with applying the friction-reduc ⁇ ing agent.
  • the axle can be heated either electrically or with the aid of steam or some other heating medium, for instance oil.
  • the axle 3 used will preferably be of the kind illustrated in Figure 4, i.e. a hollow axle or spindle provided with a plurality of radial holes 5. Steam, or water that has been heated electrically within the axle, is applied to the interior of the axle through a pipe 6 and then allowed to flow out through the holes 5. Water applied to the paper in vapour form in this way penetrates the paper web more effectively than water in liquid form.
  • Heating of the axle results in an ironing effect, i.e. the fibres in the innermost turn or turns of the paper web are compacted and the paper surface abutting the spindle will be smoother, thereby reducing the friction between axle and paper surface. Heating of the axle also accelerates the drying process.
  • the axle 3 may either be cylindrical, as illustrated in the drawing, or may have some other form which includes teeth, splines or the like, which may optionally be given a helical shape.
  • the axle may also have a slightly conical shape, to facilitate its withdrawal from the paper roll.
  • the axle may consist of a low friction material or may be coated with such a material.” Examples of suitable materials are nylon, acetal, teflon or low- friction treated metal alloys.

Abstract

L'invention concerne un procédé de production d'un rouleau à partir d'une bande en matière fibreuse, plus particulièrement du papier crêpé doux ou toute autre matière non tissée, telle que du papier d'essuyage, du papier-ménage ou du papier hygiénique. La bande (2) est enroulée sur un axe d'enroulement non consommable (3) présentant un diamètre de 35 à 100 mm. Afin de faciliter le retrait de l'axe du rouleau après l'enroulement de la bande autour de celui-ci, un agent réduisant la friction (4) est appliqué sur celui-ci ou sur le ou les premières spires de la bande. Cet agent peut être de l'eau dans laquelle un agent tensio-actif ou tout autre lubrifiant a été éventuellement ajouté, ou de l'huile, du triglycéride, du silicone, du Téflon<TM> ou l'équivalent. L'axe (2) peut être chauffé électriquement ou à l'aide de vapeur, l'agent étant appliqué simultanément de manière à réduire la friction entre la bande et l'axe.
