A method for forming a lap pin is disclosed, the lap pin being used with a cotton picker in one of the first stages of the processing of cotton from its baled condition into yarn. A lap pin is employed in the machine in order to roll up the first portion of the processed cotton into a lap. The lap pin is a single piece of forged steel having its end turned down to final dimensions for positioning within the picker. The sharp corners at the two ends are provided to accurately size the unit but the unit itself is completely of one piece construction to eliminate breakage at joints or securing points of a multi-piece lap pin, and the material is selected of high carbon steel to provide a spring action to accommodate foreign material which is always found present in the cotton as it passes through the picker.
