Definitions

  • US 3,414,459 discloses a method for embossing and binding together two plies of cellulose wadding, according to the technique called spikes against spikes.
  • the two plies are waffled separately by means of identical metal cylinders which are provided with pins and which cooperate respectively with rollers with a rubber coating.
  • the vertices of the protuberances are then coated on one of the folds with a suitable adhesive.
  • the two plies are connected to each other by the vertices of the protrusions by clamping between the two embossing cylinders set in rotation relative to each other so that the spikes come tip to tip.
  • This technique requires that both cylinders have symmetrical patterns and that the pins of the two cylinders coincide perfectly in the clamping range. A radial or circumferential offset between the pins of the two cylinders may result in a lack of connection in certain areas of the resulting complex sheet.
  • US 5 173 351 proposed using patterns with different pitch in at least one direction on the two embossing rolls to ensure at least one bonding point on the elementary complex sheets obtained by cutting the complex sheet coming out of the installation.
  • An offset of the two units between them can be achieved by a translation or by a rotation of the impression of the pattern of a embossing cylinder with respect to the pattern of the other cylinder.
  • the two plies are interconnected, by the technique known as spikes against spikes, but with a shift of the two patterns in one direction.
  • the non-coincident protuberances are arranged, between coincident protuberances, somewhat in the manner of what is obtained with the technique that allows to obtain a structure called "nested". These protuberances are not tied to the other fold and create pockets.
  • the density of the pins must be greater than 10 pins and less than 30 per cm 2 and preferably between 15 and 20 pins per cm 2 .
  • Measurements have made it possible to count the points of connection for different types of patterns. These measurements are performed by image analysis.
  • the gray value generated by the carbon footprint of the bonding points relative to a pointless reference value is determined by means of a camera and then a coefficient is applied as a function of the average area occupied by a single point.
  • the image can then be transformed into a binary (black-and-white) image that is more contrasted than the gray-scale start image.
  • This operation is done using graphical software such as Photoscop (ADOBE) or Picture Publisher (MICOGRAFX). At this point, it is possible to measure the percentage of the black area representing the link areas using these same softwares.
  • Figures 2a to 2d show the distributions of the bonding points for complex sheets having embossed folds with identical and staggered patterns respectively corresponding to the patterns shown in Figures 1a to 2d.
  • the installation for producing the complex sheet according to the invention is known per se and of the type used to make two point-to-point folds.
