A 1948 field study by A. E. Poehlmann of the Gates Rubber Company on picking motions of Crompton and Knowles looms that use off-set pickers. It argues for applying minimum power to the picking motion and discusses bunters, shuttle camming and breakage, binder and power adjustment, worn picker sticks, and the choice between reversible and non-reversible, rawhide and synthetic pickers. It gives step-by-step instructions for installing a reversible picker, adjusting bunters and checking stick overtravel, and says when to reverse a picker. Seven diagrams illustrate the picking mechanism.
