Abstract
A thermosetting unit, in particular for a textile printer, includes a pair of stationary supports, a thermosetting roller extending between said stationary supports and rotatably carried by said stationary supports around a longitudinal axis thereof, a stationary infrared lamp extending inside said thermosetting roller and having opposite ends supported by said stationary supports, and a temperature-uniforming device housed inside the thermosetting roller.
Claims12
A thermosetting unit, comprising:
- a pair of stationary supports,
- a thermosetting roller having a longitudinal axis, extending between said pair of stationary supports and rotatably carried by said pair of stationary supports around said longitudinal axis,
- a stationary infrared lamp extending inside said thermosetting roller and having opposite ends supported by said pair of stationary supports, and
- a temperature-uniforming device housed inside the thermosetting roller, the temperature-uniforming device including at least one longitudinal bar fixed to the thermosetting roller and projecting radially inwardly from an inner surface of the thermosetting roller,
- wherein said at least one longitudinal bar produces a swirling movement of air between the infrared lamp and the inner surface of the thermosetting roller during rotation of the thermosetting roller around said longitudinal axis.
