PURPOSE: To make it possible to change bobbin arrangement of doffed full bobbins only by doffing operation of a bobbin doffer of wagon type, by providing a bobbin doffing bar of the bobbin doffer with bobbin exchanging arms for the front and the rear alternately, setting a device for changing interval between the exchanging arms.
CONSTITUTION: The fork 67 of the bobbin exchanging arm 68 for the rear attached to the bobbin doffing bar 18b for setting empty bobbins is made to pass between the two guide levers 69 of right and left of the bobbin exchanging arm 68 for the rear attached to the bobbin doffing bar 18a for doffing full bobbins, and distance in the direction of front and rear of the bobbin doffing bars 18a and 18b is lessened. Change in intervals of front and rear, and right and left of the bobbin exchanging arms 66 and 68 for the front and the rear is carried out synchronously by the motor 65 for changing arrangement, and control is simplified.
