摘要： A bobbin head assembly for a maypole type circular braiding machine contains a spindle unit, a braiding material spool with braiding material and a bobbin head. The bobbin head contains a compensation plate and a torsion spring extending helically around the extended axis of the spindle unit. The torsion spring has a nose bent radially inwards towards the center at each of the two ends of the torsion spring coils. A spring seat is attached on the compensation plate, for receiving the torsion spring with a spring abutment element for fixing the nose of one spring end in a circumferential direction of the torsion spring. A fixing collar adjustably fixes the nose of the other spring end in the opposite circumferential direction at different positions along the circumferential direction. The position of the fixing collar can be secured in the circumferential direction with respect to the bobbin head.
