Definitions

  • the invention relates to a device for separating multi-layer continuous form sets or the like provided with transverse perforations, with a tear-off arrangement of two transporters arranged at a distance from one another in the transport path of the set, wherein the front transporter in the transport direction can be driven at a higher speed than the rear transporter by one Tearing to create a tensile stress triggering the transverse perforations in the section of the set located between the conveyors.

  • elongated separators are arranged between successive layers of the set, which extend in the transport direction between a rear attachment point behind the rear transporter and a front attachment point in front of the front transporter.
  • the conveyors are each formed by the set between pairs of transport rollers, that at least one of the two transport rollers of each pair of transport rollers extends only over a portion of the width of the set perpendicular to the direction of transport, and that the separators in the remaining area of the set width run through the pairs of transport rollers. It can be provided that the at least one transport roller of each pair of transport rollers is subdivided into at least two partial rollers arranged at a distance from one another, and that the band-shaped separating members run between the partial rollers.

Abstract

Le dispositif pour découper des ensembles de formules (14) disposées en bandes continues munies de perforations transversales à l'aide d'un agencement de déchirement (22) formé de deux paires de rouleaux transporteurs (72 et 74) espacées l'une de l'autre est constitué de manière telle que les deux paires de rouleaux transporteurs (72 et 74) sont entraînés à la même vitesse jusqu'au moment où la prochaine perforation transversale parvient entre les deux paires de rouleaux (72 et 74). A ce moment-là, la vitesse d'entraînement de la paire de rouleaux aval est doublée, ce qui provoque le déchirement de la perforation. Les emplacements individuels des parties détachées de l'ensemble sont délimités par des bandes de séparation (30); chaque partie détachée peut être acheminée vers une case de réception particulière. La longueur à découper peut être fournie manuellement à une installation de commande ou peut être lue par un détecteur (202) à l'aide d'un marquage correspondant de la bande continue (14).
