Hence the dispensing time is very short, thereby allowing live triggering in response to sensing of movement of the transfer plate.
  • the disc 51 is rotated so that the deposits on its surface are at right angles to the other deposits 61.
  • the extent of rotation of the disc 51 may be different, to provide a different orientation for the line of deposits 61 on its surface relative to those on the remainder of the plate 50.
  • the substrate 100 is pressed by a roller 70 of silicone material so that the deposits 61 transfer onto the underneath surface of the substrate 100.

  • the substrate 100 is now ready to be placed on a liner, or on another label which has release panels on its top surface.
  • a stack 201 of substrates may be fed to a station 250 for application of adhesive deposits as described above and may then be applied to a bottle by action of atop roller 301 and bottom cradle rollers 302 and 303.
  • a transfer plate 400 is moved, and the dispenser 60 controlled, so that there is a longitudinal line of deposits 410 along approximately half of the length of the plate 400, on a part 402, from one end to the centre of a disc-shaped internal component 401.

  • a bottom substrate sheet has adhesive deposit applied by transfer from the transfer plate and the top surface of the top sheet has deposits applied directly, and subsequently compress by way of a non-stick roller or other re-usable non-stick material.
  • This provides efficient manufacturing of two labels. If this technique is performed with multiple sheets joined by perforated lines, then there is not only double the number of simultaneous manufacturing due to the top and bottom sheets, but a further multiple is achieved by each substrate being in multiple parts joined together for later separation (for example as shown in Fig. 8).
  • Glue dots 650 and 651 are deposited by the dispensers 60 onto the top of the transfer plate 500 (Fig. 9(a)).

Abstract

Appareil de fabrication d'étiquette et processus ayant une chaîne de fabrication présentant une plaque de transfert (50) qui est déplacée de sorte qu'un motif souhaité de dépôts d'adhésif (61) est appliqué à une surface de transfert (52, 53). Le mouvement comprend la rotation d'un disque (51) avec une surface de transfert (53) après dépôt d'adhésif, de sorte que le motif de dépôt 2D change, par exemple d'une ligne droite à une forme transversale. La plaque de transfert (50) globale peut être déplacée dans son intégralité pour une plus grande polyvalence dans les motifs de dépôt 2D avant le transfert sur le substrat d'étiquette (100).
