DEVICE FOR RELEASING TIGHT FITTING BETWEEN SPINDLE AND BOBBIN OF SPINNING FRAME

摘要

PURPOSE:To enable the accurate doffing in an auto-doffer while transferring the doffer continuously, by attaching a bobbin-lifting member to the auto-doffer in a manner to be movable along the direction opposite to the transfer direction of the doffer in a state engaged with the lower end of the bobbin. CONSTITUTION:The bobbin 37 fitting closely to the spindle 1 is pulled up from the spindle by the auto-doffer running continuously along the spindle row. A pushing member 21 to push up the bobbin 37 by engaging with the lower end of the bobbin 37 is made to be movable opposite to the running direction of the auto-doffer when the pushing member 21 is engaged with the lower end of the bobbin 37, i.e. in a manner to be restorable to the original position of the auto-doffer without changing the relative position to the bobbin 37 when the pushing operation is completed and the engagement with the bobbin 37 is released.
