Method of separating labels from a carrier strip

Claim 1

A method of automatically separating labels from an elongated carrier strip having sprocket holes uniformly spaced therealong and including first and second abutting parallel carrier strip portions carrying labels bridging and adhesively attached to both of said carrier strip portions, said method comprising the steps of: mounting said carrier strip for movement along a path substantially contiguous with a planar surface having a substantially V-shaped recess including first and second edges; pulling each of said first and second carrier strip portions at a substantially first linear rate from a position down-path from said first and second edges to move said strip portions around said edges in diverging directions to successively separate each label from said carrier strip portions; feeding said first and second carrier strip portions from a position up-path from said first and second edges in a manner tending to reduce their rate of movement to less than said first linear rate to thus create and maintain tension in said carrier strip portions; and wherein said step of pulling and/or said step of feeding includes cooperating with said uniformly spaced sprocket holes either down-path or up-path from said first and second edges to control the movement of said carrier strip to prevent any cumulative differential linear movement between said first and second carrier strip portions.

Claim 2

A method of automatically separating labels from an elongated carrier strip having sprocket holes uniformly spaced therealong and including first and second abutting parallel carrier strip portions carrying labels bridging and adhesively attached to both of said carrier strip portions, said method comprising the steps of: mounting said carrier strip for movement along a path substantially contiguous with a planar surface having a substantially V-shaped recess including first and second edges; pulling each of said first and second carrier strip portions at a substantially first linear rate from a position down-path from said first and second edges to move said strip portions around said edges in diverging directions to successively separate each label from said carrier strip portions; feeding said first and second carrier strip portions from a position up-path from said first and second edges in a manner tending to reduce their rate of movement to less than said first linear rate to thus create and maintain tension in said carrier strip portions; and wherein said step of pulling and/or said step of feeding includes cooperating with said uniformly spaced sprocket holes either down-path or up-path from said first and second edges to control the movement of said carrier strip to prevent any cumulative differential linear movement between said first and second carrier strip portions.

Claim 4

A method of automatically separately transferring labels to objects conveyed past a labelling station from a carrier strip comprised of first and second parallel carrier strip portions carrying a plurality of labels releasably adhered therealong and bridging said first and second carrier strip portions, said method comprising the steps of; separately pulling each of said first and second carrier strip portions at a common first linear rate from a pulling station located down-path from said labelling station, along a path including a first common portion extending from a supply station past said labelling station; separating said first and second carrier strip portions from one another proximate to said labelling station and guiding said first and second carrier strip portions along separate first and second branch portions of said path extending from said labelling station to said down-path pulling station; engaging each label substantially at or slightly up-path from where said first and second carrier strip portions are separated for applying each engaged label to an object conveyed past said labelling station; engaging said carrier strip up-path from said labelling station to produce drag on said carrier strip portions tending to reduce their rate of movement to less than said first linear rate to thus create and maintain tension in said carrier strip portions; and controlling the rate of movement of said carrier strip portions by cooperating with sprocket holes uniformly spaced along said carrier strip so as to prevent any cumulative differential linear movement between said first and second carrier strip portions.

Claim 5

A method of automatically separately transferring labels to objects conveyed past a labelling station from a carrier strip comprised of first and second parallel carrier strip portions carrying a plurality of labels releasably adhered therealong and bridging said first and second carrier strip portions, said method comprising the steps of; separately pulling each of said first and second carrier strip portions at a common first linear rate from a pulling station located down-path from said labelling station, along a path including a first common portion extending from a supply station past said labelling station; separating said first and second carrier strip portions from one another proximate to said labelling station and guiding said first and second carrier strip portions along separate first and second branch portions of said path extending from said labelling station to said down-path pulling station; engaging each label substantially at or slightly up-path from where said first and second carrier strip portions are separated for applying each engaged label to an object conveyed past said labelling station; engaging said carrier strip up-path from said labelling station to produce drag on said carrier strip portions tending to reduce their rate of movement to less than said first linear rate to thus create and maintain tension in said carrier strip portions; and controlling the rate of movement of said carrier strip portions by cooperating with sprocket holes uniformly spaced along said carrier strip so as to prevent any cumulative differential linear movement between said first and second carrier strip portions.
