SR4 Compact Automatic Label Rewinders

Rewind small rolls with compact equipment.

The SR range comprises compact label rewinders, with a fixed core on SR4 or an adjustable core on SRA.

La gamme SRA/4 regroupe des réenrouleurs d’étiquettes. Ils organisent les séries d’étiquettes après impression pour les ateliers de conditionnement et d’identification, en préparant des rouleaux pour les opérations ultérieures.

Le réenroulement de la bande imprimée forme une bobine exploitable pour les étapes suivantes. Il évite de laisser les étiquettes s’accumuler librement en sortie d’imprimante. Le format compact propose un mandrin fixe ou ajustable selon le modèle. Le sens de rotation et la vitesse sont réglables pour adapter le bobinage.

Principaux avantages :

  • Réenroulement des étiquettes après impression
  • Sens de rotation réglable pour adapter le bobinage
  • Vitesse ajustable selon le travail à réaliser
  • Mandrin fixe ou ajustable selon le modèle
  • Format compact pour faciliter l’intégration sur le poste
  • Arrêt automatique avec alarme pour surveiller le fonctionnement
