Definitions

  • the present invention relates to a device for laying and perforation of a flexible reinforcement and / or guide strip, a corrugating comprising this device, and a method for laying and perforation of a strip using this device and a packaging case from of this process.
  • These boxes are also provided with at least one line of perforations, which follows the aforementioned strip by crossing it even sometimes, this line of perforations serving as a precut line, i.e. a line guide provided with rupture primers for the aforementioned opening of the checkout.
  • This method of the prior art has the disadvantage of achieving the laying and perforating the strip laid on the plate in two stages separate requiring two different machines, resulting in a cost price important and successive manipulations.
  • this technique anterior requires precise positioning between the blade of the press or rotary cutter and the plate on which the strip to be mounted is mounted perforated so that all the teeth of the blade penetrate the strip and the cardboard in a substantially identical transverse position relative to the edge of the strip and do not miss the strip if the strip is also to be perforated.
  • we use a relatively wide band and the results obtained are not uniform due to significant variations in the transverse position of the perforations along the strip.
  • the invention aims to provide a device for laying and perforating a flexible reinforcement and / or guide strip, which can be adapted on a corrugating machine and overcoming the disadvantages above of the technique used in the prior art.
  • this device is particularly advantageous in that it makes it possible to carry out successively the positioning, fixing and then linear perforation of a flexible strip of reinforcement and / or guide. So, since the same device performs these two operations, these are carried out almost simultaneously, without manipulation between these two operations so this transformation step is done quickly, at a relatively low cost, and ensuring the line of perforations is perfectly aligned with the strip, the perforations being evenly distributed along the strip and all similar.
  • the present invention also relates to a machine for undulating comprising at least one device of the type which has just been described, placed along the corrugator at a location corresponding to the end of the production of the sheet, characterized in that the said sheet of material is made of double-sided corrugated cardboard, in that said tablecloth drive mechanism and said main chassis belong to said waving machine and in that said mechanism drive has a variable drive speed.
  • the incorporation of the device for laying and perforating the tape directly on the corrugating machine saves a lot of time the two operations.
  • the quality of the cut is improved by the fact that it is carried out hot at the outlet of the line manufacture of corrugated cardboard.
  • performing the perforation directly on the corrugating machine facilitates alignment between the perforation line and the strip and therefore reduces the number of different transformation for the realization of objects, such as cases from the corrugated cardboard tablecloth, which generates reduction in the cost price of these objects.
  • the invention also relates to a defined packaging case according to claim 15.

  • a strip 230 extends, inside the box 220, on the four walls lateral 224a to 224d along a rectangular contour parallel to the bottom 222 and to the upper wall 226.
  • This strip 230 can be continuous or else discontinuous and consisting of several pieces which completely cover the periphery of the box 220.
  • This strip 230 and three of the four walls side have two pre-cut lines 232 and 233, preferably parallel to each other, delimiting between them the guide portion 236 and the gripping means.
  • the two portions of the strip 230 located on either side of said guide portion 236, that is to say between one of the pre-cut lines 232 and 233 and one of the lateral edges of the strip 230, forming two reinforcing portions 238 from the edge of the two parts 220a and 220b of the wall of the box 220 which constitutes an article.
  • the two pre-cut lines 232 and 233 are interconnected by at least one opening line 242 in the form of a transverse slot and by two end of opening lines 243 in the form of a transverse slot situated at the ends of the pre-cut lines 232 and 233.
  • the lines of pre-cuts 232 and 233 extend over the entire width of the side walls 224a, 224b, 224d and over a small portion of the width of the side wall rear 224c, in the areas adjacent to the side walls 224b and 224d.
  • the opening line 242 is placed in the middle of the section of the strip 230 extending over the front side wall 224a and the two end lines opening 243 connect the two ends of the lines pre-cuts 232 and 233 near the edges of the box 220 which connect the side wall 224c to the side walls 224c and 224d.
  • each section of the guide portion 236 adjacent to the opening line 242 we enter each section of the guide portion 236 adjacent to the opening line 242 by pulling on this section of the guide portion to one of the end of opening lines 243 so as to completely remove the guide portion 236 of the strip 230 located along the lines of pre-cuts 232 and 233 and between the two opening end lines 243.
  • the box 220 is then separated into two parts 220a and 220b, thanks to the opening formed on the side walls 224a, 224b and 224d.
  • a box 220 can be opened and closed, the section 230c of the strip 230 located on the rear side wall 224c constituting a hinge for the box thus formed.
  • the free edge of the two parts 220a and 220b extending over the side walls 224a, 224b and 224d being reinforced by the reinforcement portions 238 which provided, during the separation, a cutting safe and easy by leaving a smooth and even edge 246 on the cover at the same time 220b and on the box body 220a.
