Definitions

  • a ligature or wrapping of some sort such as steel strapping
  • some sort such as steel strapping
  • the load is more likely to remain in position during transport to a desired location.
  • the strapping is made of fabric, wire, metal or plastic and secured by metal seals. These seals join the opposing overlapping ends of the strapping together, and become crimped or flattened forming joints in the seal used to secure and prevent movement of the load.
  • a layer of hard, small grit particles inside the joints of the metal seal is a layer of hard, small grit particles, preferably at least layered in the marginal edge areas or the overlapped end portions of the strapping and between the adjacent surfaces of the strapping end portions so that when the overlapped end portions are secured together, the particles embed into the adjacent face of the strapping ends and held the ends against relative longitudinal movement.
  • the particles provide a raised texture, which enables the seal to maintain a stronger hold on the straps.
  • the strap ends could slide or slip with respect to each other and with respect to the seal, causing the strap to separate and become unsecured.
  • Exemplary strap seal is disclosed in US-A-3,089,233, and US-A-3,237,256.
  • a seal that provides the cost effective results of the grit-type seal, and that reduces the release of the attached grit particles from the seal.
  • a seal prevents the relative movement of the end portions of the strapping, while maintaining secure bundling of the cargo and maintaining its strength during transport and lifting.
  • the invention includes the introduction of a metal seal that is coated to prevent the release of particle grit from the inner surface of the seal.
  • the present coated grit seal prevents the grit from contaminating and possibly damaging tools used to secure the seal to the strap to form a joint.
  • the seal includes a seal body having inner and outer surfaces, at least one layer of grit particle material disposed on the inner surface of the seal body, and at least one layer of coating material over the grit particle material.
  • the grit particle material can be disposed on the entire inner surface of the seal.
  • the inner surface of the seal can define marginal end areas on which the grit material and coating material are disposed. That is, the seal defines flanges on opposing lateral sides of the seal and the grit particle material is disposed on the flanges of the seal.
  • the coating material can be lacquer, shellac, paint or glue.
  • the coating material can be pigmented or clear. Two layers of the coating material can be applied over the grit particle material.
  • the grit particle material can be about 40-120 mesh. Preferably, the grit material is about 60-100 mesh.
  • a method of preventing grit particles from loosening from the seal includes the step of coating the grit particle material with at least one layer of coating material.
  • the method includes selecting the coating material from lacquer, shellac, paint or glue.
  • the coating material can be pigmented prior to coating.
  • the method can include grit particle material being disposed on the entire inner surface of the seal.
  • the method can include providing a seal that defines flanges on opposing lateral sides of the seal, and having the grit particle material disposed on the flanges of the seal.
  • the method can further include the step of coating the grit particle material with two coats of the coating material.
  • an improved inner coated grit seal 10 that eliminates the release of grit particles.
  • the seal 10 maintains its strength and effectively secures strapping portions to one another.
  • the seal 10 is provided with an inner seal surface 18 with at least one coated gripping surface. When crimped, the seal 10 distorts the overlapping strap end 20,22 and prevents the ends of the strap from becoming unsecured from the seal 10.
  • such cargo is typically secured by one or more straps.
  • These straps facilitate transport, prevent sifting of the cargo and enable lifting of the cargo from one area to another.
  • the overlapping ends 20,22 of the strapping material are joined together by the seal 10 to prevent relative movement of the end portions 20,22 from one another.
  • the seal 10 is preferably a metal member, e.g., steel, however it can be formed from of any material that can withstand crimping and still effectively secure the joined strapping ends 20,22 in place during lifting and transport.
  • the strapping material there are several different varieties available that are currently in commercial use.
  • the strapping material for which the present coated grit seal 10 can be used includes, without limitation: steel, aluminum, fabric and/or plastic.
  • typically the straps can be either treated or untreated, coated, painted, waxed, heat treated and a like.
  • a joint 24 is formed by the seal 10 and the overlapped end portions 20,22 of the strap.
  • the joint is formed by the seal 10 being pressed (e.g., crimped) firmly into engagement with the strap end 20,22, such that the strap becomes deformed.
  • the above-noted patents disclose such a deformed strap configuration.
  • the inner surface 18 of the seal 10 which comes in contact with the strapping end 20,22 has an irregular configuration or character.
  • the seal inner surface 18 that contacts the strap 20,22 has affixed thereto granules of a hard material, referred to as grit 26.
  • the grit 26 is affixed to the inner surface 18 which provides s high friction environment at the joint 24, securing and preventing the movement of the overlapping strapping ends 20,22.
  • the grit particles 26 can be disposed on the entire seal inner surface 18 (FIG. 3).
  • the seal 10 can define marginal end areas or flanges 14, 16 at lateral opposing sides of the seal 10, and the particles 26 can be applied to the flanges 14,16 (FIG. 4), allowing the center 12 to be free of grit particles.
  • the flanges 14,16 are secured over the overlapped ends (20,22) the particles 26 embed into the adjacent faces of the overlapped strapping ends to hold the ends against relative longitudinal movement.
  • the grit material 26 is secured to the seal 10 to create a positive gripping of the strap end 20,22 without tearing the strap, which is essential to the integrity of the joint 24.
  • the grit 26 tends to loosen from the seal inner surface 18. This loosened grit can, if introduced into seal-forming tools (e.g., crimping tools), cause excessive wear and possibly failure of the tools.
  • a seal 10 in accordance with the present invention greatly reduces and can eliminate the loose grit problem.
  • the grit particles 26 are preserved or coated with one or more thin layers of coating, as indicated at 28, over the grit particles 26.
  • the layers of coating 28 may vary from one to as many as five layers, depending on the type of coating used.
  • the grit 26 is coated with one or two layers of coating 28.
  • the coating 28 over the grit particles 26 can include lacquer, shellac, paint and/or glue, which is preserved over the attached grit particles 26 on the seal inner surface 18.
  • the coating 28 may be clear or pigmented, and may vary in thickness. While it will be recognized that a heavier coating 28 over the grit 26 can effect the penetration and joint efficiency of the seal 10 itself in cases where a heavier coating 28 is used, a larger grit particle 26 size can eliminate the reduction in joint efficiency and penetration of the seal.
  • the grit particle material 26 varies in size.
  • the particle 26 size used in the present invention is one that can be sufficiently preserved to the seal inner surface 18 to prevent the release of the particles 26, while still maintaining the effectiveness of the grit 26 in securing the strapping ends 20,22 from movement.
  • the grit 26 is aluminum oxide having a particle size of about 40 to 120 mesh, and more preferably from about 60 to 100 mesh.
  • the grit 26 is coated 28 with one or two coats or layers of lacquer. Those skilled in the art will recognize that while the coating 28 "covers” the grit 26, the grit 26 nevertheless "bites” or is forced into the strapping end 20,22 by the force applied during crimping.
