Abstract
Abstract Apparatus for removing labels from cylindrical cans involves the use of air jets which are directed by nozzles between the label and the can. The jets have sufficient force to rupture the label. An exhaust fan draws air around the can to draw the ruptured label away from the can. While the apparatus is best suited to remove sleeve like labels which are not adhesively secured to the can at least partial removal of labels which are adhesively secured to the can may be achieved.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
116 words
A dry method for removing wrap-around labels or carriers from containers, said wrap-around labels or carriers comprising labels or carriers in which the opposing ends are brought into overlapping relationship and adhesively secured together but allowing access to air or gas between the label or carrier and the container, the method comprising the steps of feeding the containers along a path through a stripping station, directing a gas or air jet between each label or carrier and its container, said gas or air jet being of sufficient force to rupture the label or carrier absent melting thereof, and creating a gas or air drought to carry the label or carrier after rupture away from said path.
Claim 2
Dependent Claim
116 words
A dry method for removing wrap-around labels or carriers from containers, said wrap-around labels or carriers comprising labels or carriers in which the opposing ends are brought into overlapping relationship and adhesively secured together but allowing access to air or gas between the label or carrier and the container, the method comprising the steps of feeding the containers along a path through a stripping station, directing a gas or air jet between each label or carrier and its container, said gas or air jet being of sufficient force to rupture the label or carrier absent melting thereof, and creating a gas or air drought to carry the label or carrier after rupture away from said path.
Claim 3
Dependent Claim
102 words
A dry method for removing wrap-around labels or carriers from containers, the wrap-around labels or carriers being labels or carriers in which opposing ends thereof are brought into overlapping relationship and are adhesively secured together but allowing access to air or gas between the label or carrier and the associated container, the method comprising the steps of feeding containers along a path through a stripping station and directing a dry fluid jet between each label or carrier and its associated container at a sufficient force to rupture the label or carrier absent melting thereof and effect its removal from its associated container.
Claim 4
Dependent Claim
102 words
A dry method for removing wrap-around labels or carriers from containers, the wrap-around labels or carriers being labels or carriers in which opposing ends thereof are brought into overlapping relationship and are adhesively secured together but allowing access to air or gas between the label or carrier and the associated container, the method comprising the steps of feeding containers along a path through a stripping station and directing a dry fluid jet between each label or carrier and its associated container at a sufficient force to rupture the label or carrier absent melting thereof and effect its removal from its associated container.
