Definitions

  • the invention relates to a system for longitudinally corrugating strips or webs.
  • a solution is already known in which a progressive longitudinal corrugation takes place, by which successive pairs of corrugating rollers, arranged horizontally, are fitted in such a way that the different pairs of rollers are set one behind the other forming a train of progressive corrugating rollers.
  • This solution although bringing about corrugation in a longitudinal direction of the strip of paper, brings with it the problem that the installation occupies a lot of space, necessary for the train of the pairs of corrugating rollers, and, all things considered, entails a cumbersome and complex installation.
  • a longitudinal corrugating system for laminar strips or webs comprising at least one roller or drum, around which are juxtaposed, in a sector of its circumferential area, a series of peripheral rollers of smaller diameter which have some corrugating elements in the way of annular grooves which are increased in number from the first peripheral roller to the last; these peripheral rollers are pressed against the drum which has its surface profiled to correspond to the corrugating elements of the peripheral rollers or is resiliently deformable to take the shape of the corrugating elements; all this in such a way that passing a laminar strip or web between the peripheral rollers and the drum causes a progressive corrugation of the said strip, with corrugations aligned in the direction of advance of the strip.
  • the corrugating unit described is completed by a set of rollers which transport the strip from the said forming unit to a collecting spool; at the exit point of the formed strip the arrival point of respective smooth sheets is situated. These are juxtaposed over both surfaces of it to be transported together with it to the collecting spool, the corresponding gluing mechanisms being then brought in, so that the said smooth strips can then be stuck onto the corrugated strip, forming as the end product one single section with it.
  • a cutting mechanism is situated, which, when actuated, enables the sheet which is to be corrugated to be cut into longitudinal pieces, so that when sandwiched between smooth sheets at the exit point, the resulting section remains at intervals without an intermediate corrugated strip.
  • a cutting mechanism is situated, which, when actuated, enables the sheet which is to be corrugated to be cut into longitudinal pieces, so that when sandwiched between smooth sheets at the exit point, the resulting section remains at intervals without an intermediate corrugated strip.
  • corrugating laminar strips such as strips of paper for the manufacture of corrugated cardboard
  • the formation of the corrugations is already known both in a transverse direction in relation to the direction of advance of the strip, and in a longitudinal direction, i.e. with the corrugations parallel to the direction of advance of the strip to be corrugated.
  • the subject of the invention relates to a system of longitudinal corrugation of laminar strips, for application basically in the manufacture of corrugated cardboard, eliminating or mitigating the problems described above.
  • this new system is based on the utilisation of a basic large diameter roller or drum (1) see Fig. 1, on a wide peripheral area of which is juxtaposed a series of smaller diameter rollers (2), the said peripheral rollers (2) being provided, see Figs. 4 to 9, with a series of annular grooves (3), which increase progressively in number over the successive rollers from the centre to the outside.
  • the drum (1) itself has annular grooves, corresponding inversely in the higher and lower parts with those grooves (3) of the peripheral rollers (2), or is of an elastic material which is able to distort according to the abovementioned grooves (3) of the rollers (2).
  • the said corrugation takes place progressively over the width of the strip (4), from the centre to the edges, which is effective, thanks to the progression in number of grooves (3) of the rollers (2), according to the succession of them which comes into contact with the web (4) as it advances, succeeding in this way in the corrugation (6), which necessarily has to occur with gathering of the web (4) from the edges to the centre, not causing excessive transverse tension which could cause the web (4) to break or to crease resulting in an imperfect, uneven finished product.
  • Fig. 12 it can be seen how, at the exit point of the abovementioned corrugating unit, the arrival is arranged of smooth webs (7 & 8) which come from other feeding spools juxtaposed one above and one below the surfaces of the corrugated web (4), forming with it a sandwich which is led through a series of guide rollers (9) to a corresponding collecting spool (10).
  • a cutting mechanism (13) has been incorporated, whose operation is optional, which, when operated, enables the web (4) to be cut in longitudinal portions, as can be seen from Fig. 13, so that the final sandwich between the smooth webs (7 & 8) and the corrugated web results at intervals with portions without intermediate corrugated cardboard web (4).
  • Figs. 10 and 11 can be seen those piles of portions of corrugated cardboard resulting respectively, firstly from a functional version of the system without actuating the cutter (13) and secondly, represented in Fig. 11, actuating the cutter (13), in accordance with the last operational form described.
  • the result obtained is translated into some pieces of cardboard with smooth areas and with areas having a corrugated central section, which is covered over its entire surface by smooth webs (7 & 8).
  • These pieces can contain the portions with a corrugated central section which are required, with those dimensions and shapes which will make them suitable for their application in the sphere of packaging, since the sandwich can offer a content of corrugated cardboard in the areas where more resistance is required, and be smooth in the remaining area, with the characteristic that the total covering of the intermediate corrugated part or parts will prevent humidification in later use.
  • peripheral rollers (2) have been arranged on a movable mounting, either following a longitudinal axis, or pivoting, or by means of eccentrics in such a way that, by conventional means, they are applied against the drum (1).
  • peripheral rollers (2) can turn freely, as satellites of the drum (1), or all have their own motive means, or alternately motive means which would be synchronised with those of the drum (1).
  • the connecting of the laminar web (4) with the drum (1), above all when it is cut into portions, is carried out via already known means, either mechanical, such as vacuum inside the drum (1), or via pressure curtains of compressed air.
  • a solution is represented of vacuum means utilising a vacuum pump (14).
  • This invention thus provides a new system of longitudinal corrugation with which, starting from the same principal of progressive shaping of the strip to be corrugated, the problems of the prior art described above are eliminated or mitigated, giving an installation which requires a smaller number of rollers, resulting in much less cost and at the same time giving an innovative arrangement of the rollers enabling the dimensions of the space required to be kept to a minimum, allowing the corrugating unit to be combined without any great difficulty with the plant required for feeding and collecting the laminar web or strip, and using it in conjunction with other mechanisms for incorporating other smooth laminar webs on the surfaces of the corrugated web to obtain corrugated cardboard in its finished state, all of which with much smaller dimensions.
