  • This invention relates broadly to the transfer by pumping means, active solvents and liquids, of various viscosities, either individually or in combination with other materials and particularly as it applies to the pumping of inks, adhesives, lacquers, paints and cleaning fluids in the graphic arts field.
  • Another object of the present invention is to provide a method and apparatus for adjusting the flow charac- SUMMARY OF THE INVENTION
  • the tube through which the material is pumped must be elastomeric in nature and yet resistant to the solvency action of such solvents as methyl ethyl keytone, toluene, xylene, ethyl acetate and other esters, and various alcohols either individually or in various combinations.
  • One essential embodiment of this invention is the development of an elastromer material which does meet the required performance specifications and has proven to be commerically practicable.
  • the elastomer is produced by effecting a polymerization of poly vinyl alcohol and a monomer such as methylmeracrylate.
  • the polymerization is accomplished by immersion of the basic poly vinyl alcohol material in the monomer and subsequent exposure to radiation.
  • Poly vinyl alcohol is hydroscopic in nature and normally subject to rapid deterioration by exposure to water or water soluble solvents. When subject to the described processing treatment, the end result is highly resistant to water as well as being inert when subject to contact with the previously described solvent materials.
  • An additional embodiment of this invention is the use of an outer tube or jacket which is also elastomeric and may be composed of the same or a dissimilar material, such as P.V.C.
  • the outer tube insulates the inner tube from the abrasion and friction caused by the roller, thus extending the life of the inner tube.
  • the apparatus as embodied in this invention has been run for continuous extended periods before tube failure necessitated a change and this has exceeded the requirements for commercial justification and approval.

  • a conducting tube 98 which is deformable and has a memory, that is, it will return to its original shape after being deformed.
