sumiko kiyooka photograph magazine 2010.23 AutoCAD Design Suite 2018 invention relates to a roll-forming machine in which successive material webs are fed in a flattened condition from respective supply rolls onto a forming and pressing station wherein the material web is formed into a tubular blank. A roll-forming machine of the aforementioned kind is shown in U.S. Pat. No. 4,551,568 wherein a take-up roll is disposed to receive the material web from a supply roll. It is known to feed material webs through a rolling mill, e.g. a tubular rolling mill, by applying a pair of suction rolls to an entry side of the roll mill in a roll-forming machine of the aforementioned kind. If the material web is flat and, therefore, the suction rolls cannot grip the web tightly, the material web will have a tendency to sag between the suction rolls. It is also known, in a roll-forming machine, to install a pair of suction rolls on a side of a roll-forming station, upstream from the station, to grip the web tightly. Such suction rolls, however, cause formation of a longitudinal and peripheral lip on the edge of the web. These lips give the web a rough appearance and the material webs are susceptible to tearing because of their small thickness..02 for children 1 to 3 years old, 1.41 for children 4 to 8 years old, and 1.15 for children 9 to 12 years old.^[@zoi200170r19]^ AUC of 0.84 for the original model and 0.84 for the final model suggests good discriminating ability. However, if the model is applied in the United States, the AUC is only 0.67 because of the relatively low prevalence of prolonged suctioning.^[@zoi200170r19]^ We also validated the model for daily and seasonal variations. We tested the performance in only 1 month because of the complexity of seasonal variations. The results showed a good performance, with AUC of 0.87 and 0.90 in validation set 1 and validation set 2, respectively. The reason for the overestimated estimates of the first half of the year (
