  • the profile is usually made of metallic material but can be made of aluminum, other rigid/semi-rigid material, or combination of both. Accordingly, the term “profile” is used throughout this disclosure to mean board or strip having ribs or tabs, and is made of metallic and/or other rigid/semi-rigid material.
  • the protruding rib 110 b that protrudes out at the bottom end is used to insert or place a front panel once the metal rule 110 has been folded into a desired shape or letter.

  • the cutting unit 20 is provided near the profile feeding path 30 to cut a portion of the protruding ribs 110 a and 110 b in an angle to facilitate folding of the profile.

  • This profile 110 is fed into the folding machine 2 through a profile supply unit 90 , and is transferred through the profile feeding path 30 in the direction shown in FIG. 3 . While the profile 110 is being transferred through the profile feeding path 30 , a portion of the protruding ribs 110 a and 110 b is cut in an angle by the cutting unit 20 to facilitate the folding of the profile 110 . Once the profile 110 is properly cut by the cutting unit 20 , the profile folding unit 101 folds the cut profile 110 .
  • FIG. 4 shows the portion (see Part B) of the protruding ribs 110 a and 110 b cut in a predetermined shape on both sides of the folding line (see Line A).
  • the cutting unit 20 in anticipation of the profile 110 being folded along Line A, provides two “V” cuts on each side of Line A and one “V” cut centered at Line A, for a total of five “V” cuts.
  • cuts in this embodiment are described as five “V” cuts, any shape and/or any number of cuts can be made on the ribs to facilitate the folding process.
  • five “V” cuts can provide easy folding of the profile 110 into approximately 300-degree angle (see angle C in FIG. 5 ).
  • less or more number of cuts can provide easy folding of the profile 110 into angles less than or greater than 300 degrees.
  • the cut shape can be made in “U” shape or any other appropriate shape rather than a “V” shape.

  • Another cut 114 is made centered at Line A.
  • two more cuts 116 are made on the right side of Line A, as shown.
  • scratch lines or cut lines 118 are made along the center of the cuts 112 , 114 , 116 to further facilitate the folding of the profile 110 .
  • the scratch lines 118 are made carefully on the same side of the profile as the protruding ribs 110 a and 110 b so that profile 110 can be folded along those lines without cutting the profile 110 at those lines. Seen in detail in FIG. 4A , the scratch lines 118 make tiny ridges on the surface of the profile 110 . In one example, the depth of the ridges made by the scratch lines 118 is approximately one-third of the thickness of the profile. This leaves approximately two-thirds of the thickness of the profile for easier folding with completely cutting the profile. Further, in the illustrated embodiment of FIG.
  • the V cuts are made on both ribs 110 a and 110 b so that the tip of the V shape cuts from the open edge 150 all the way to the closed edge 120 of the ribs 110 a and 110 b , and can penetrate slightly further into the profile to match with the tiny ridges made by the scratch lines 118 .
  • the cuts made on the rib are angled so that the open edge 150 has a larger angle than the closed edge 120 .
