Abstract

A godet for heating and advancing yarns which includes a stationary support member and a rotatable member which includes a heatable godet jacket. The temperature of the godet jacket is measured by means of temperature sensors, the output signals of which are transmitted by induction from the rotatable member to the stationary member. The godet is provided with an electronic memory, which is connected with the temperature sensors and stores the data supplied by the temperature sensors. The memory is connectible to a data transmission unit, and the data are transmitted by induction between a stationary primary coil and a rotating secondary coil, which also provides the supply of voltage to the rotating member. In this conjunction, it is possible to transmit the data both from the rotating member to the stationary member of the godet and from the stationary member to the rotating member.
