Definitions

  • the splicing tape is comprised of a flexible support, such as paper, cloth or a polymeric film, coated with a thin layer of a polyolefin, such as polyethylene or polypropylene, which has been surface activated by, for example, flame treatment, chemical oxidation or electron bombardment.
  • a polyolefin such as polyethylene or polypropylene
  • Low density polyethylene is the preferred polyolefin and the thickness of the polyolefin layer is typically in the range of from about 0.1 to about 3 mils.
  • the support can vary in thickness from about 1 mil to about 8 mils.
  • a preferred support material is oriented polyethylene terephthalate film with a thickness of from about 1 to about 3 mils.
  • the splicing tape is particularly advantageous for use in joining together separate lengths of photographic material to form a continuous web adapted to processing by continuous machine methods.

Applications published under the Defensive Publication Program have not been examined as to the merits of alleged invention. The Patent Oflice makes no assertion as to the novelty of the disclosed subject matter.
PUBLISHED OCTOBER 21, 1969 796,226 METHOD OF SPLICIN G SENSITIVE PHOTOGRAPHIC MATERIALS Oliver W. Kalli, 1669 Lake Ave., Rochester, NY. 14650 Filed Feb. 3, 1969. Published Oct. 21, 1969 Int. Cl. B6511 69/02 US. Cl. 156-157 No Drawing. 13 Pages Specification Sensitive photographic sheet materials, such as photographic film or paper, are spliced together with a splicing tape having an activated surface by contacting the emulsion surface of the photographic material with the activated surface of the tape and applying heat and pressure sufiicient to obtain a strong bond. The splicing tape is comprised of a flexible support, such as paper, cloth or a polymeric film, coated with a thin layer of a polyolefin, such as polyethylene or polypropylene, which has been surface activated by, for example, flame treatment, chemical oxidation or electron bombardment.
Low density polyethylene is the preferred polyolefin and the thickness of the polyolefin layer is typically in the range of from about 0.1 to about 3 mils. The support can vary in thickness from about 1 mil to about 8 mils. A preferred support material is oriented polyethylene terephthalate film with a thickness of from about 1 to about 3 mils. In effecting splicing, heat and pressure are applied for a suflicient period of time to effect bonding, typical times being from about 1 to about 5 seconds.
The splicing tape is particularly advantageous for use in joining together separate lengths of photographic material to form a continuous web adapted to processing by continuous machine methods.
