Definitions

  • the present invention relates to a method of preparing a flying or permanent splice between a first and second sheet material, to the splices thus obtained and to splicing tapes suitable for splicing a leading edge portion of the outer turn of a roll of sheet material to another sheet material.
  • Splicing tapes can be used for preparing a joint between two sheet materials such as, for example, between the leading edge portion of the outer turn of a roll of sheet material and another sheet material.
  • the splicing operation can be performed in a static or a dynamic mode.
  • first and second sheet material may be positioned first in the desired configuration relative to each other, and one or more splicing tapes are then applied in order to join the two sheets together. It is also possible to apply the splicing tape or tapes to one of the sheet materials first. Then the second sheet material is provided, positioned in the desired configuration and the two sheet materials are joined. Splices which are obtained in a static mode of preparation are often referred to as permanent splices. Depending on the configuration of the two sheet materials relative to each other, it can be differentiated between butt splices, overlap splices and staggered overlap splices, respectively. The different configurations are shown and explained in WO 95/2 9,115.
  • splices which are obtained in a dynamic mode of operation, are usually referred to as flying splices.
  • a conventional way of making a flying splice tape uses destructible nose tabs as is described in WO 95/29,115.
  • the new roll is appropriately prepared or "dressed" for splicing, as is shown in Fig. 1a which was taken from WO95/29, 115.
  • the leading edge 35 of the outermost turn 32 of the new roll of sheet material 30 is cut, for example, in the form of a W or V or in another appropriate shape.
  • a double-sided adhesive tape 24 is applied to the leading edge portion of the outermost turn 32 which is releasably adhered to the next-to-the-outer turn 31 by the nose tabs 23.
  • the new roll of sheet material 30 is then accelerated to the same speed as the running web sheet of the previous, depleting roll.
  • the running web sheet is then pressed against the new roll 30 and pasted to the double-sided adhesive tape 24 on the outermost turn 32 of the new roll 30.
  • the previous roll is typically cut off from the running web sheet.
  • the nose tab is then subjected to the tractive force exerted by the running web sheet. The nose tab breaks thereby releasing the temporary joint between the outer turn 32 and the next-to-the-outer turn 31 of the new roll of sheet material 30.
  • FIG. 1b An alternative configuration for applying a flying splice which is used in the state-of-the-art is shown in Fig. 1b which was adapted from WO 95/29,115.
  • a nose tab which is suitable for preparing a flying splice is described in GB 2,294,235.
  • the nose tab comprises two adhesive layers which are adhered to the under-surface of the leading edge portion of the outer turn and the upper-surface of the next-to-outer turn, respectively.
  • the nose tab furthermore comprises two thin paper layers which are attached to two adhesive layers and embrace a silicon lacquer layer.
  • the new roll of sheet material is then furthermore prepared by applying a double-sided adhesive tape to the leading edge of the outer turn to provide a configuration similar to that of Fig. 1a or 1b, respectively.
  • the paper web sheet from the depleting roll which is advanced is adhered to the exposed part of the adhesive layer and the exposed adhesive layer of the double-sided tape, thereby causing the lacquer layer to cohesively split into two parts.
  • breaking the nose tab of GB 2,294,235 leaves behind two non-tacky surfaces.
  • Both permanent and flying splices should provide a flexible, strong connection between the two sheet materials or webs and should maintain substantially all of the properties of the sheet material; for example, if the sheet material is paper which can be printed or coated, the splice is preferably thin, flexible, printable, coatable and also repulpable.
  • the splice is preferably thin, flexible, printable, coatable and also repulpable.
  • small destructible adhesive tabs 26 are sometimes applied not only at the noses of the leading edge 35 but, for example, also along the diagonal edges of the leading edge 35 in Fig. 1a or over the lateral edges of the leading portion 34 of the outer turn 32 to the sides of the roll 30 (see Fig. 1b). Configurations like those of Fig. 1a and 1b are time consuming to apply and require the application of double-sided adhesive tapes and destructible nose tabs.
