Abstract
A hollow roller, which is heatable with steam, has an inner wall. It is rotatably mounted and has a steam supply channel opening into the interior and a siphon pipe, which opens into the interior coaxially to a centre longitudinal axis, with a suction opening located adjacent to the inner wall. The siphon pipe is held in a rotary feed-through, which is pivotable relative to the centre longitudinal axis of the hollow roller about a pivot angle α in such a way that the spacing b of the suction opening from the inner wall is adjustable.

A hollow roller (1) which is heatable with steam,
- which has a roller shell (2) with an inner wall (25), two end walls (3, 4), a centre longitudinal axis (5) and an interior (13),
- which is rotatably mounted,
- which has a steam supply channel opening into the interior (13) coaxially to the centre longitudinal axis (5) and
- which has a siphon pipe (14) which opens into the interior (13) coaxially to the centre longitudinal axis (5), with a suction opening (24) located adjacent to the inner wall (25),
- wherein the siphon pipe (14) is formed rigidly and is held in a rotary feed-through (16), which is pivotable relative to the centre longitudinal axis (5) about a pivot angle α in such a way that a spacing b of the section opening(24) from the inner wall (25) is adjustable,
- wherein the siphon pipe (14) is rigidly connected to the rotary feed-through (16),
- wherein the rotary feed-through (16) is mounted on pivot bearings (28), said pivot bearings (28) are each carried on a bearing rod (26, 27), and
- wherein the bearing rods (26, 27) are screwed on either side of a bearing journal (7) of the end wall (4) and a housing (17) of the rotary feed-through (16).
