Definitions

  • the invention relates to a device for cross-perforating a plurality of webs according to the preamble of claim 1.
  • sacks are necessary, the walls of which consist of different layers.
  • an inner, moisture-impermeable layer which often consists of a thin plastic film, can be surrounded by a paper layer, which absorbs the forces caused by the goods to be transported. So that each of these materials can be welded or glued to itself in the floor layer, the perforations used to separate the tube sections must be introduced into each individual material web so that they are not congruent with the perforations of the other material webs.
  • Such offset perforations are referred to as staggered perforations and can only be introduced into the individual material webs before the tube is formed.
  • Devices for applying staggered perforations are known.
  • these comprise a sawtooth-shaped knife, which rotates around an axis, and a counter-pressure roller on which the web to be perforated runs and in whose grooves the teeth of the knife can be immersed.
  • the distance between the knives and the axis around which they rotate can be changed.
  • the distances between the counter-pressure rollers and the axes around which the knives rotate must also be displaceable.
  • This counter pressure roller provides the counter pressure for the perforation process. As a rule, they allow the knives to pierce the webs during perforation without the knives being damaged.
  • Grooved or brushed rollers are mainly used for this purpose.
  • the counter-pressure rollers can usually be moved together.
  • all counter-pressure rollers are mounted on a carrier which is movable relative to the machine frame in which the axes about which the knives rotate are mounted.
  • one end of the handlebars is rotatably mounted on the carrier.
  • the other ends of the handlebars are rotatably mounted in the machine frame, so that a parallelogram guide is created for the wearer.
  • another lever is attached to it, on which a drive acts. This drive is rotatably mounted in the machine frame.
  • a disadvantage is that such a device requires a large number of bearings and is therefore mechanically complex.
  • the object of the invention is therefore to propose a device which is kept mechanically simpler.
  • the object is achieved by the characterizing feature of claim 1.
  • the carrier is essentially displaceable along a line which connects the axes of the counter-pressure rollers and the axes about which the associated knives rotate.
  • linear guide means are arranged between the carrier and the machine frame, the guide direction of which runs essentially parallel to the line connecting the axes of the counter-pressure roller and the axes of rotation about which the knives rotate. In this way it is possible to move the counter-pressure rollers in the radial direction towards the axes of rotation of the knives.
  • the guide means comprise running rails which are fastened to the carrier and are slidably mounted in guides fastened to the machine frame.
  • Such guide means allow the carrier to be moved without great effort.
  • tilting of the carrier is also excluded, so that all counter-pressure rollers maintain a precisely uniform distance from the axis of rotation of the knives.
  • a linear drive is provided with which the carrier can be moved relative to the machine frame.
  • Various drives are conceivable here, such as a linear motor or a manually operated traction mechanism.
  • the linear drive comprises a spindle-spindle nut combination driven by a motor, by means of which the rotational movement of the motor axis is converted into a linear movement of the spindle nut via the spindle.

Abstract

L'invention concerne un dispositif de perforation transversale de plusieurs bandes (1). Ce dispositif comprend plusieurs arbres de rotation (2) autour desquels tournent des lames (4), et plusieurs contre-cylindres de pression (7). Une bande à perforer (11) défile respectivement entre une lame (4) et un contre-cylindre de pression (7). Les contre-cylindres de pression (7) sont disposés sur le support (6, 17) de manière mobile par rapport au bâti de machine (1) dans lequel sont montés les arbres de rotation (2) des lames (4). Ce support (6, 17) permet de régler la distance entre les contre-cylindres de pression (7) et les arbres de rotation (2) des lames (4) à la même valeur et simultanément pour tous les contre-cylindres de pression (7). L'invention est caractérisée en ce que le support (17) peut être déplacé sensiblement parallèle à une ligne (17) qui relie les arbres des contre-cylindres de pression (7) et les arbres de rotation (2) autour desquels les lames (4) tournent.
