Abstract
A sealing unit for a heat treatment apparatus for textile threads comprises an upper roller (7) and lower roller (8) between which a conveyor belt (8) passes. The seal between the rollers and the frame (2) of the unit is formed by an upper (29) and lower sealing element (30) with PTFE covers (35) which slide along the rollers, and by two lateral plates (42) contacting the extremities of said covers and of the rollers. Each of said covers is divided into at least two elastically interconnected pieces (35a, 35b) so that the covering shortens when the lateral plates draw closer to each other due to wear against the roller extremities.
