Abstract
A container or array of containers that is are sealed with a peelable seal is transported via a conveyor along a processing path toward a desealing station at which an adhesive surface having a width substantially the same as or greater than the width of the seal is pressed against the upper surface of the peelable seal. A collection rod applies a downward pressure on the adhesive surface, pressing it against the seal and keeping the container or container array in position on the conveyor as the plate moves with the conveyor. As the leading edge of the seal passes the collection rod, the adhesive surface is rolled upward, away from the plane of the seal, pulling up on the leading edge of the seal to separate it from the container or container array while the container or container array is held down by the roller. The removed seal is then discarded.

20. A take-up reel in a device for removal of a film seal from an object, wherein the device comprises a source roll of adhesive tape, a first tape path portion, a translation means for moving the object relative to the first tape path, a collection rod within the first tape path for pressing the adhesive tape against the film seal as the object is moved past the collection rod, a take-up spindle disposed within a second tape path portion substantially perpendicular to the first tape path portion for supporting the take-up reel and a driver to rotate the take-up spindle, the take-up reel comprising:
-
a cylinder releasably supported on the take-up spindle for receiving a leading end of the adhesive tape and rotating to collect used adhesive tape and removed film seal that is adhered to the adhesive tape; a first side flange and a second side flange disposed on opposite ends of the cylinder for centering the used adhesive tape and removed film seal on the cylinder; and means for preventing slippage relative to the take-up spindle and maintaining a uniform pulling force on the adhesive tape to pull the adhesive tape along the tape path, wherein the pulling force produces a lifting motion at the collection rod to peel the film seal away from the object. - View Dependent Claims (21, 22, 23, 24, 25, 26)

27. A take-up reel in a device for removal of a film seal from an object, wherein the device comprises a source roll of adhesive tape disposed on a source spindle, a first tape path portion, a translation means for moving the object relative to the first tape path portion, a collection rod within the first tape path for applying pressure to the adhesive tape and the film seal as the object is moved past the collection rod, a take-up spindle disposed within a second tape path portion substantially perpendicular to the first tape path portion for supporting the take-up reel and a driver to rotate the take-up spindle, the take-up reel comprising:
-
a cylinder having a coaxial flange disposed at each end, the cylinder having means for releasable mounting on the take-up spindle, wherein the cylinder receives a leading end of the adhesive tape and rotates to collect used adhesive tape and removed film seal that is adhered to the adhesive tape; and means for preventing slippage relative to the take-up spindle and maintaining a uniform pulling force on the adhesive tape to pull the adhesive tape along the tape path, wherein the pulling force produces a lifting motion at the collection rod to peel the film seal away from the object. - View Dependent Claims (28, 29, 30, 31)
