Heated roll
First Claim
1. A heated roll comprising a hollow cylindrical shell defining an internal chamber into which steam may be fed, a syphon pipe fixed within said chamber and having one open end near to the lowermost position therein, the pipe having a part of its length substantially concentric with the roll and located within a rotary sealed joint outside of the chamber for drainage of condensate therefrom, said pipe being fixed to a non-rotating part of the rotary joint;
- characterized in that said non-rotating part is mounted with a clearance fit on a pair of fixed guide bars; and
in that a plurality of jacking screws are operable between said non-rotating part and said guide bars to adjust the position of the non-rotating part and thus the pipe relative to the rotational axis of the roll.

Abstract
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).
