Abstract
The disclosed doffing apparatus is for use in a spinning machine including a mechanism for winding a yarn in the form of a cheese or package, a device for cutting the yarn fed to the winding mechanism when the cheese becomes full and an air suction device for sucking the cut yarn which is continuously fed even after cutting. This doffing apparatus comprises an operation member which is movably positioned in the vicinity of the air suction device and cutting device so that the operation member is operatively interconnected to the air suction device and cutting device, and opening of the air suction device and operation of the cutting device are performed by the movement of the operation member. In this doffing apparatus, release of a full cheese from the winding mechanism also can be performed by this operation member.
