Abstract
Abstract The force required to pull a 2400 tex glass roving through a melt impregnation compounding process was studied. Pulling force was continuously measured by suspending the double belt puller in a sling held stationary by a force transducer. Process variables such as roving pulling speed, number of cylindrical pins, pin diameter, and melt temperature were studied using polymide 66 and polypropylene polymers. The results suggest that the tension build‐up in the roving is caused by a combination of two effects: viscous shear stresses in a thin polymer‐rich layer between the roving and the pin, as well as frictional forces caused by roving contact with the pin. A simple mathematical model is developed and used to adequately describe the experimental results.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
