This can be achieved by respectively providing a line sensor that detects a line sensor, a processing device that processes the detection result of the line sensor, and a display device that displays the processing result of the processing device. With this, it is possible to automatically detect the amount of accumulated heat by measuring the coating thickness of the adhesive as the amount of heat stored during the production of the adhesive tape.

になっている。This device is directly connected to the process of applying adhesive to one or both sides of the tape (not shown), and the adhesive is applied to the tape to form adhesive tape (product to be inspected) T. A heating device 1 that radiates heat rays (infrared rays) to the adhesive layer of the tape T is disposed in parallel with the adhesive tape T running between it and a pick-up reel 10 for winding up an object. This heating device 1 is installed on the tape running destination side.
An optical system consisting of an infrared transmission filter 3, an imaging lens 4, and a slit plate 5 is provided through a shielding plate 2 that blocks heat rays from The amount of heat stored in the adhesive layer is converted into an amount of electricity and inputted to the processing device 7.
The output is output to an external output terminal 8 and a display device 9.
本発明の粘着テープの厚み検査装置は以上のように構成
されており、以下この装置を用いて粘着剤層の厚み測定
について述べる。The pressure-sensitive adhesive tape thickness inspection device of the present invention is configured as described above, and the measurement of the thickness of the pressure-sensitive adhesive layer using this device will be described below.

御され均一な厚みに塗布される。The adhesive layer applied to the tape is uniformly heated by a heating device 1. This heating causes heat to accumulate in the adhesive layer. Since the amount of heat storage is proportional to the thickness of the adhesive layer, this amount of heat storage is passed through the infrared transmission filter 3 to the imaging lens 4 and the slit plate 5.
The image is continuously formed on the line sensor 6 by the slit width in accordance with the running of the tape. The line sensor 6 generates an amount of electricity corresponding to the amount of heat storage, the processing device 7 processes this amount of electricity so that it can be displayed numerically, and the display device 9 displays the value or issues an alarm if the processing result is outside the allowable range. Warn workers. Further, signals for automatically controlling the running speed of the tape and the amount of adhesive flowing out are sent from the external output terminal 8. This automatically or manually controls the amount of adhesive applied to ensure a uniform thickness.
