This article describes utilizing infrared (IR) radiation focused by reflectors for use with diskette manufacturing apparatus, and more particularly with forming the folds in the diskette envelope assembly. The arrangement provides for fine mechanical adjustment. This system provides a quick response as well as the capability of independently programming the radiation intensity and the radiation exposure time. The radiation intensity may be controlled through a range of ten percent to one-hundred percent power (10% to 100%). The time may be set from zero time through ten seconds (0 thru 10 seconds). Contact heating has been used to thermally set the top and side folds of plastic diskette envelopes.
