Two piece pin and sleeve stripping system

A device for separating and stripping waste material from a blank during a manufacturing process, the device comprising:

• a separating mechanism including first and second separating cylinders, the second separating cylinder having an interior portion;
• a pin and sleeve assembly coupled to the second separating cylinder, the pin and sleeve assembly including a pin and a sleeve slidably coupled therewith, the sleeve being selectively slidable between a retracted position in which the pin is exposed, and an extended position in which the pin is concealed, wherein a fluid flowing through the aperture is adapted to move the sleeve from the retracted position to the extended position to thereby conceal the pin;
• and
• a tube positioned within the interior portion of the second separating cylinder and extending across a substantial length thereof, the tube having at least one aperture generally aligned with the pin and sleeve assembly, wherein the tube is in fluid communication with a fluid source,
• wherein the pin is adapted to couple the waste material to the second separating cylinder, and the tube is adapted to receive a fluid from the fluid source and direct it through the aperture and slide the sleeve into the extended position to thereby conceal the pin.

A device for stripping waste material from a separating mechanism, the separating mechanism including first and second separating cylinders, wherein a pin and sleeve assembly is coupled to the second separating cylinder and includes a pin and a sleeve slidably coupled thereto, the sleeve being selectively slidable between a retracted position in which the pin is exposed, and an extended position in which the pin is concealed, wherein a fluid flowing through the aperture is adapted to move the sleeve from the retracted position to the extended position to thereby conceal the pin, the device comprising:

• tube means associated with the second separating cylinder and having aperture means formed therein, the tube means being in fluid communication with a fluid source;
• and
• means for receiving a fluid in the tubing means and directing it through the aperture means,
• wherein the pin is adapted to couple the waste material with the second separating cylinder, and wherein the tube is adapted to receive a fluid from the fluid source and direct in through the aperture to thereby slide the sleeve into the extended position to conceal the pin.

A method for separating and stripping waste material from a blank, the method comprising:

• providing a separating mechanism having first and second separating cylinders;
• providing a pin and sleeve assembly coupled to the second separating cylinder, the pin and sleeve assembly having a pin and a sleeve slidably coupled therewith, the sleeve being selectively slidable between a retracted position in which the pin is exposed, and an extended position in which the pin is concealed;
• providing a tube having at least one aperture formed therein, wherein the aperture is generally aligned with the pin and sleeve assembly;
• coupling the waste material to said pin;
• and
• forcing a fluid to flow into the tube and through the aperture to slide the sleeve from the retracted position to the extended position to thereby conceal the pin and strip the waste material from the second separating cylinder.
