<p>A baseplate(31) supports two rolls(32,33) through which the film(5) passes. A lever rotates above the baseplate and a heat sensor(42) at the upper end of the lever contacts one of the rolls to record the temperature. Firm contact between the sensor and roll is achieved by a spring(43) acting on the lever. The sensor(42) is a heat sensitive resistor. The spring(43) can be a rotating spring or a V-shaped leaf spring whose one end(431) is supported on the lever(41) and the other end on the baseplate(31). A connection between lever and spring is made by an pin(442), which passes through openings in both parts, and a circular locking clip.</p> |
