Abstract

A method and apparatus are provided for obtaining a temperature profile of a moving substrate, particularly a fabric web moving through a linear drying or heat-setting oven. Without arresting fabric movement, a temperature sensing probe, preferably a thermocouple mounted on a support, is placed in engagement with a specific point of the fabric web, sharpened pins on the support, penetrating and engaging the web. The temperature probe is connected by a wire to a reel. The reel has a handle held by the operator about which the reel rotates to letout and takeup the wire while providing electrical continuity between the wire and a stationary recorder. Level unwinding of the wire takes place from the reel as the probe moves with the fabric through the oven, the probe continuously monitoring the temperature of the specific fabric point and feeding signals back to the recorder through the wire. Without arresting fabric movement, once the probe is through the oven the support is removed from the web, and the reel is rotated to takeup the wire. The wire is disconnected from the probe prior to the wire being reeled up, and the probe is carried back to the oven entrance to repeat the procedure as necessary.
