Definitions

  • ABSTRACT A structure of a roll of a filmy article such as a paper provided with at least one thin resinous layer covering at least one side surface of the roll for protection of the roll from deformation, damage and contamination and a method of making the roll structure.
  • the present invention relates to an improved structure of a roll of a filmy article and a method for making such a roll, more particularly to a roll structure of a filmy article provided with at least one detachable resinous covering layer formed on at least one side surface of the roll and a method for making such a roll.
  • a protector plate is attached to side surfaces of the roll in a coaxial arrangement.
  • This protector plate is used favorably when the filmy article forming the roll is wound on a cylindrical support.
  • an axial projection of the protection plate is inserted into a central bore of the cylindrical support.
  • this axial projection is replaced with a screw receiver and the protector plate is urged to the side surface of the roll by connecting the wall of the box with the screw receiver of the protector plate.
  • one side surface of the protector plate purposed for contact with the rolls side surface is provided with a formed sheet layer.
  • side edges of the filmy article of the roll are provided with adequately roughened surfaces. Due to an increased frictional contact between the layers of the filmy ar ticle, telescoping between the layers can be mitigated.
  • the first attempt that is, the use of the protector plate, is difficult to employ when the roll is of a noncore construction.
  • the screw-fastening type protector plate is not suitable in a case where the roll is not encased within a container.
  • the last type attempt is not employable when such provision of the roughened edge surface is not favored in view of the end use thereof.
  • no solution is given concerning the protection of the roll from surrounding dust.
  • the use of the protector plate or its modification is not effective in protecting the roll from losing its shape during actual transportation, more particularly in actual transportation of the roll or a long distance. It was confirmed also that a very strong construction is required for the container so as to adopt the screw fastening type protector plate.
  • a principal object of the present invention is to provide an improved structure of a roll of a filmy article free from the sticking of surrounding dust.
  • Another object of the present invention is to provide an improved structure of a roll of a filmy article free from accidental losed telescoping between the wound layers of the filmy article, thereby effectively protecting the roll from undesirably losing its shape.
  • Still another object of the present invention is to provide an improved structure of a roll of a filmy article adaptable for various types of rolls without any difficulty.
  • a further object of the present invention is to provide an improved structure of a roll of a filmy article which can be applied to any type of roll without any kind of damage to the filmy article.
  • a still further object of the present invention is to provide a method for making the roll of the above-described structure in a very simple manner without any modification of the filmy article or roll and without any use of additional articles such as a protector plate.
  • the roll structure of the present invention is provided with at least one resinous covering layer formed detachably on at least one side surface of the roll. Formation of such a resinous covering layer is done by spreading the resinous substance to the surface using a brush, a roller or a sprayer.
  • FIG. 1 is a longitudinal sectional view of an embodiment of the roll structure of the present invention
  • FIGS. 2A and 2B are longitudinal sectional views of modifications of the roll structure shown in FIG. 1,
  • FIG. 3 is a partly longitudinal sectional view of a modification of the embodiment shown in FIG. ll.
  • FIG. I an embodiment of the roll structure of the present invention is shown, wherein a filmy article is wound on a cylindrical support I forming layers 2 and a resinous layer 3 is formed covering at least one side surface of a roll 4 composed of the layers 2 of the filmy article.
  • the roll 4 is formed by the layers 2 of the filmy article wound on a cylindrical support I, however, the roll 4 may be formed in a noncore construction, also.
  • the resinous layer 3 is formed entirely covering the side surface of the roll 4.
  • FIG. 2A A modification of the embodiment shown in FIG. 1 is illustrated in FIG. 2A, wherein the resinous layer 3 covers not only the side surface of the roll 4 but also the peripheral surface portion of the roll 4 adjacent to the side surfaces. Because the peripheral surface portion adjacent to the side surfaces of the roll 4 is covered by the resinous layer 3, sticking of contamination and above-mentioned shiners to those portions can be effectively prevented, also.
  • the internal peripheral surface of the cylindrical support 1 is also covered by the resinous layer 3 at its portions near the side ends of the roll 4.
  • the wound filmy article layers 2 are fixedly secured to the cylindrical support I by the resinous layer 3, thereby the accidental removal of the resinous layer 3 from the side surface of the roll 4 due to slippage between the wound filmy article layers 2 can be effectively prevented.
  • a protector plate 6 is favorably used in combination with the roll structure of the present invention and the protector plate 6 is provided with a central projection 7 to be inserted into the central cave of the cylindrical support 1.
  • the resinous layer is purposed for a temporary protection of the edge-portion of the layer wound on the cylindrical support and the protective layer should be easily removed from the side surface pf the roll 4 just before the actual use of the filmy article. Therefore, the material resinous substance must easily form such a covering layer and be easily detached from the side surface of the roll. In case when the material substance lacks in cohesive property, it is difficult to form such a protective layer in a cohering relationship to the rolls side surface, while the protective resinous layer is difficult to remove from the side surface of the roll when the material substance has an excessive cohesive property. Besides, the substance must be provided with a sufficient durability against deformation of the roll due to application of external loading during actual storage or transportation thereof.
  • the protective layer must be provided with a moderate elastic property, strength, softness and. durability against long use with reduced cohesiveness to the roll s side surface.
  • the formed covering layer should be sufficiently resistant against external attack applied to the roll during actual storage or transportation thereof. Further, the formed resinous layer has to be removed from the rolls side surface without any practical damage on the filmy article forming the roll.
  • the covering layer must be easily formed on the roll's surface by, for example, a brush or sprayer.
  • the material substance composing the resinous covering layer should not contain substances harmful to the quality of the filmy article forming the roll to be protected.
  • the protective layer must be resistance against attack by water, wetness, climate or injury from salt.
  • the material substance for forming the resinous covering layer of the present invention is desirably and advantageously chosen from a copolymer mainly composed of polyvinyl chloride and vinyl chloride such as methyl-ethyl ketotie, parastizol and organosol; a cellulose derivative such as cellulose acetate butylate and ethyl cellulose; a polyvinyl alcohol, for example, produced through a graft polymerization of polyvinyl alcohol with a, B-ethylene-unsaturated carboxylic ester such as acrylic acid, methacrylic methyl, ethyl propyl or 2 ethyl.

  • a cellulose derivative such as cellulose acetate butylate and ethyl cellulose
  • a polyvinyl alcohol for example, produced through a graft polymerization of
  • Formation of the resinous covering layer may be done by spreading the material substance over the purposed surfaces by using any of a brush, a sprayer or a roll.
  • the desirable thickness of the resinous layer is experimentarily confirmed to be thicker than 0.01 mm.
  • EXAMPLE I A roll of biaxially drawn polyethylene-terephthalate film of 25p. thickness, 500 mm. width and 1,000 m. length was used as a test specimen.
  • a sample of the present invention was prepared by forming a copolymer of acrylic acid ester methacrylic acid ester covering layer of 0.5 mm. thickness on side surfaces of the roll.
  • Thusly prepared sample was subjected, after a complete drying thereof, to a transportation test together with a roll of a same nature but having no covering layer.
  • Evaluation of the test result was made as to the number per m of contamination sticking to the roll 's side surface before and after transportation, in which evaluation, only dust having an average diameter larger than p were counted. Together with this dust test, frequency of telescoping between the film layers was counted also for each 12 rolls and the obtained result was as is shown in Table I.
  • EXAMPLE 2 Fifty rolls of biaxially drawn polyethylene-terephthalate film of 25p. thickness, 500 mm. width and 1,500 m. length were used as test specimens, Side surfaces of the rolls were covered with a detachable resinous emulsion layer of 0.8 mm. thickness having a composition shown in Table 2 in a manner shown in FIG. 2A and the rolls were heated at 70 C. for 15 minutes. Next, the rolls were wholly covered with filmy sheet and provided with protector plates as shown in FIG. 3. Thusly prepared 50 samples were subjected to a transportation test and the evaluation was done in a manner the same as that employed in the foregoing example. Together with this, 50 sample rolls not covered with the protective layers were also subjected to the same test and the results are shown in Table 3. A remarkable effect is presented by the employment of the art of the present invention.
  • An improved roll structure comprising a roll of film material, and at least one detachable resinous layer covering at least one end surface of said roll of film material, wherein said resinous layer is an acrylic paint of a detachable nature, containing an emulsion composed of polyvinylacetate and polyvinylalcohol, and a silicone resin.
  • An improved roll structure as claimed in claim I further comprising a protector plate attached to said covered end surface in pressure contact therewith.
