Definitions

  • the present invention is generally in the field of forming a continuous sheet of laminate material containing superabsorbent polymer and relates specifically to lamination of large continuous sheets of fabric to form enclosed cells, each containing a measured quantity of superabsorbent polymer material.
  • Such composite sheets have many uses and are important items of commerce.
  • the superabsorbent material readily absorbs water and can then be frozen to provide a substitute for ice and dry ice.
  • the invention comprises a method and machine for rapidly and reliably producing a continuous composite sheet and forming it into uniform rolls.
  • Composite as used here means a sheet comprising two layers of laminated textile material between which discrete quantities of a superabsorbent polymer are arrayed in a regular pattern. Those quantities of polymer are kept separate by the fusing or otherwise sealing together of the two layers of textile material.

Smooth pinch rollers 15 and 20 rotate throug surface friction of the fabric as it is pulled through th series of rollers by chain 18 acting through sprockets 17, 17a 17b and 17c on the powered rollers 8, 11, 21 and 27. weight.

  • Roller 19 is provided to allow additional contact time for he penetration and fusing by causing the composite sheet 25 remain in contact with heated roller 11 until said sheet enters a second pinch between roller 11 and roller 20.
  • Sa second pinch roller 20 is carried on heated pattern roller and unheated pattern roller 21 approximately as shown in Fi 1.
  • the weight of smooth pinch roller 20 creates a pin between rollers 20 and 11 and also between said roller 20 a roller 21.

Guide slots 33 and 3 for rollers 15 and 20 are the same on eac side.
  • This second application of force the ribs helps facilitate a bond or seal at bond or seal lin 52a and 52b to allow operation of the machine at higher spee or at lower roll temperatures than might be possible with single pinch roller. In most cases both higher speed and low temperatures will be possible while still producing an adequa seal or bond.

  • Roll 21 is adjusted in its rotational relationship to roller directly over the pattern established by roller 11 by looseni sprocket 17b on shaft 28 of roller 21, making said rotation adjustment and relocking the sprocket to said shaft. When th is done with chain 18 tightly over sprockets 17a, 17b, a under sprocket 36, the new rotational relationship will fixed.
  • Sheet 25 is now complete after passing between smoo roller 20 and pattern roller 21.
  • the sheet 25 may be qui lumpy because of the mounded condition of powder deposits which were deliberately placed in small mounds so that sea lines 52a and 52b which would later by formed around sai deposits would maintain a maximum distance from any seal to an powder deposit margin in order to avoid possible inclusions o powder within said seals.

  • Take-up drive roll 22 may also be powered from chain through its sprocket 17c. Said take-up drive roll 22 employed to furnish a drive means for the actual producti take-up roll 2g because a difficult problem exists at th point in production. Friction between the semi-plast composite sheet and the various smooth and pinch rollers very low, so that any tendency to "overfeed", that is, to ro up the production blanket faster than the fabric was passi through the patterned rollers may cause one or both fabr s ee s o s p roug one or more p nc es , regular pattern and possible getting powder into a seal ar It is also possible to stretch some fabrics in the transverse seals 52a while they are softened in the hea zones over ribb 54. Conversely, not enough take up sp results in possible loosening of fabric 3a as it passes aro roller 8. This will allow powder to fall out of cavities prematurely and thus to contaminate seal areas of th satisfactory seals could not be made.
