Definitions

  • the inter-stand tension and rolling pressure, particularly of the last stand will be controlled to eifect little or no reduction in the last stand.
  • the pressure in the piston cylinder assemblies 19 will be set to be sufficiently high to assure the creation of the necessary interstand tension and yet being kept as low as possible so as to militate against a reduction being taken in the pinch roll units 15 and 16.
  • both entry and delivery tensions may be employed.
  • a pay-ofi reel 36 At the entry side of the stand 31, which is indicated by the arrow, there is provided a pay-ofi reel 36 and on the delivery side of the stand 32, a two roll driven tension bridle 37 is provided followed by a tension reel 38.
  • the stand 32 differs in construction from the stand 31, namely, in that piston cylinder assemblies 39 are mounted in each housing at the base thereof, which urge vertically the lower backing-up roll 35 and the lower working roll 34.
