<p>A heated roll comprising a hollow cylindrical shell (10) with a syphon pipe (14) passing into the roll from a rotary joint (13) mounted on an end thereof. A non-rotating part of the rotary joint is mounted with a clearance fit on a pair of fixed parallel guide bars (22). Jacking screws (27) threadingly engaged within a cross bar (26) attached to the non-rotating part of the rotary joint, bearing upon each guide bar thus to enable the longitudinal axes of the rotary joint (13) and the roll shell (10) to be relatively adjustable thus to determine and set an accurate position for the inner open end of the syphon pipe (12) close to the inner wall of the shell (10).</p> |
