Definitions

  • the present invention relates to a method for seaming T profiles, an apparatus for implementing the method, and a profile obtained by the method.
  • T profiles obtained by profiling a sheet metal strip are known for forming support frames for false ceilings.
  • this is provided with a plurality of longitudinal seams obtained by a process comprising a first step in which a plurality of parallel slits of length L are formed in said web spaced apart by a value H, after which a transverse punching operation is effected with a punch having the same length L and width H against a die provided in a wheel facing the punching wheel.
  • this improvement is obtained by a method for producing profiles as described in claim 1.
  • the method of the invention uses two pairs of punching wheels 2, 2', 4, 4' of vertical axis, the wheels 2, 4 being provided on their lateral surface with two rows of first punches 6 and second punches 8 which are faced on the wheels 2', 4' by two annular grooves 10, 12.
  • the annular groove 10 is a through groove whereas the groove 12 has a width slightly greater than the first groove and a depth such as to form a die for the second punches 8 of the wheel 4.
  • the first punches 6 and second punches 8 have a substantially trapezoidal longitudinal section, the second punches 8 having their major side, of length L', less than the length L of the major side of the first punches 6 and having the it cutting surface of convex shape.
  • the web 16 thereof is made to pass through the pairs of punching wheels 2, 2' and 4. 4'.
  • the first punches 6 form on the web of the strip a plurality of pairs of parallel incisions 18 having a length corresponding to the length of the first punches 6 and spaced apart by a distance corresponding to the thickness of the first punches.
  • the web 16 is then subjected to the action of the second punches 8 which effect a further punching in correspondence with the first punching.
  • the sheet metal cannot further translate because of the presence of the die formed by the groove 12, but instead the most outer portion forms a kind of collar 20 which embraces the inner portion to hence prevent longitudinal slippage of the two parallel parts facing the webs and thus ensure greater flexural rigidity.
  • the tooth of the second punches 8 is of convex shape and of dimensions less than the length of the incisions formed with the first punches 6, it does not interfere with the flared parts of the sheet metal, which are hence free to slide relative to each other.
