Chewing tobacco packing machines: a formula and form amendments set how machine capacity and duty are determined. An Explanation is inserted into rule 5 prescribing the formula S = (r/g) x n to calculate the maximum rated speed in pouches per minute, where r is motor RPM, g is overall gear ratio and n is number of funnels in a horizontal machine or number of cups in a vertical machine; rule 6(2) and multiple entries in FORM CE DEC-01 and FORM CE CCE-01 are amended to substitute 'cups' for 'tracks,' replace 'track' with 'cup or funnel,' and insert specified multiplicative factors and bracketed calculation notations to align forms and instructions with the revised capacity metric.
