A chain has alternating vertical and horizontal chain links and with each link having an oval profile. The vertical links having an end web supporting surface formed on its inside that engages with a complementary bearing surface on the end web of adjacent horizontal link. The supporting surfaces and the bearing surfaces of all end webs are widened beyond two lateral surfaces of the respective end web, and supporting surfaces and bearing surfaces associated with one another are formed in each case as complementary cylindrical surfaces extending between longitudinal limbs. A method for producing such, closed profile chain links are hooked into open profile chain links and then the latter are closed by welding. And wherein, all supporting surfaces and bearing surfaces associated with one another are formed in each case as cylindrical surfaces that complement one another.
A chain comprising alternating horizontal links and vertical links, each horizontal and vertical link having an oval profile and comprising a pair of end webs connecting two longitudinal limbs, each vertical link having a pair of supporting surfaces formed on an inside of the pair of respective end webs, each horizontal link having a pair of bearing surfaces formed on an inside of the pair of respective end webs,
A chain comprising alternating horizontal links and vertical links, each horizontal and vertical link comprising a pair of end webs connecting two longitudinal limbs, each vertical link having with a pair of supporting surfaces formed on an inside of the pair of respective end webs, each horizontal link having a pair of bearing surfaces formed on an inside of the pair of respective end webs,
A method for producing chains comprising a plurality of vertical links and a plurality of horizontal links, the vertical links and horizontal links connected in an alternating manner, the method comprising:
