Appellants describe the hot air nozzle in terms of Figure 6, shown here: opening 34 comprises large openings 36a and 36b and a restricted opening portion 38 between 36a and 36b. It was found that the restricted opening portion 38 still allows sufficient outflow of heated air to sufficiently soften the overlapping portion of the thermoplastic sheets over and under the fastening means in order to weld the thermoplastic sheets together over the interposed fastening means.
