Abstract
Abstract A splicing device includes a bracket for mounting on a sealing machine frame, a shaft rotatably mounted on the bracket, the bracket carrying a spindle on each end thereof for a roll of tape, a first handle and brake on one end of the shaft for releasably locking the arm in one position, and a second handle on the other end of the shaft for rotating the shaft and arm, a wiper roller and a separation roller mounted on the frame. A first roll of tape is dispensed from one spindle to a taping head, and a second, fresh roll of tape is on the other spindle. When the first roll of tape is almost completely dispensed, the brake is released and the arm rotated to contact the second roll of tape with the adhesive surface of the first roll. Continued rotation of the arm causes the first roll to wrap partially around the second roll, whereby a paper tab on the leading end of the second roll attaches to the first roll of tape to start dispensing the second roll of tape in overlapping relationship with the trailing end of the first roll. The arm rotates until the used roll passes between the wiper and separation rollers, whereby the trailing end of the used roll engages the separation roll and the new roll engages the wiper roll. The arm is again locked and the trailing end of the old roll is cut.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
394 words
A device for splicing rolls of adhesive tape comprising frame means; shaft means rotatable on said frame means; arm means centered on said shaft means for rotation relative to said frame means; first spindle means on one end of said arm means for carrying a first roll of tape; second spindle means on the other end of said arm means for carrying a second roll of tape; wiper roller means on said frame means outside of a circular path of travel of said spindle means during rotation of said arm means, said wiper roller means being spaced from said shaft means a distance such that the wiper roller means is outside the path of travel of a nearly used, reduced diameter first roll of tape on one said spindle means and inside the path of travel of a second, larger diameter, fresh roll of tape on the other said spindle means; and separation roller means on said frame means between said shaft means and said wiper roller means inside the path of travel of said spindle means, whereby, with the first roll of tape on the first spindle means being continuously unrolled and fed tangentially around a fixed point to a taping head, when the arm means is rotated in a direction to move the second roll of tape into contact with an adhesive side of the first roll of tape, the first roll of tape causes rotation of said second roll of tape to attach a leading end of the second roll of tape to the trailing end of the first roll of tape while the first roll of tape continues to be fed to the taping head; continued rotation of said arm means causing the second roll of tape to contact the wiper roller means for stopping arm rotation and for pressing overlapping lengths of said first and second rolls of tape together; and the first spindle means and the first roll of tape passing between the wiper roller means and the separation roller means, whereby the trailing end of the first roll of tape passed over the separation roller means to the first spindle means, so that said trailing end of the first roll of tape can be severed between said first spindle means and said separation roller means for feeding to the second roll of tape to complete the splice.

A device for splicing rolls of adhesive tape comprising frame means; shaft means rotatable on said frame means; arm means centered on said shaft means for rotation relative to said frame means; first spindle means on one end of said arm means for carrying a first roll of tape; second spindle means on the other end of said arm means for carrying a second roll of tape; wiper roller means on said frame means outside of a circular path of travel of said spindle means during rotation of said arm means, said wiper roller means being spaced from said shaft means a distance such that the wiper roller means is outside the path of travel of a nearly used, reduced diameter first roll of tape on one said spindle means and inside the path of travel of a second, larger diameter, fresh roll of tape on the other said spindle means; and separation roller means on said frame means between said shaft means and said wiper roller means inside the path of travel of said spindle means, whereby, with the first roll of tape on the first spindle means being continuously unrolled and fed tangentially around a fixed point to a taping head, when the arm means is rotated in a direction to move the second roll of tape into contact with an adhesive side of the first roll of tape, the first roll of tape causes rotation of said second roll of tape to attach a leading end of the second roll of tape to the trailing end of the first roll of tape while the first roll of tape continues to be fed to the taping head; continued rotation of said arm means causing the second roll of tape to contact the wiper roller means for stopping arm rotation and for pressing overlapping lengths of said first and second rolls of tape together; and the first spindle means and the first roll of tape passing between the wiper roller means and the separation roller means, whereby the trailing end of the first roll of tape passed over the separation roller means to the first spindle means, so that said trailing end of the first roll of tape can be severed between said first spindle means and said separation roller means for feeding to the second roll of tape to complete the splice.
Claim 3
Dependent Claim
31 words
A device according to claim 1, including first brake means between said shaft means and said frame means for releasably locking said shaft means and said arm means in one position.
Claim 4
Dependent Claim
41 words
A device according to claim 2, including second brake means between said frame means and said arm means for resisting rotation of said arm means when said first brake means is released, whereby said arm means is not capable of freewheeling.
Claim 5
Dependent Claim
41 words
A device according to claim 3, including first handle means on one end of said shaft means for operating said first brake means, and second handle means on the other end of said shaft means for operating said second brake means.
Claim 6
Dependent Claim
74 words
A device according to claim 3, wherein said first brake means include head means on said shaft means; and first friction washer means between said head means and said frame means, and said second brake means includes sleeve means on said frame means rotatably supporting said shaft means between said frame means and said arm means; flange means on said shaft means; and friction washer means between said sleeve means and said flange means.
Claim 7
Dependent Claim
29 words
A device according to claim 1, wherein said arm means defines an acute angle with the adhesive side of said first roll of tape prior to a dispensing operation.
Claim 8
Dependent Claim
103 words
A device according to claim 6, wherein said frame means includes baseplate means for mounting on one side of a carton taping machine, said shaft means is mounted beneath one end of said baseplate means, said wiper roller means is mounted beneath the other end of said baseplate means opposite the direction of feed of the first roll of tape and said separation roller means is mounted on the center of said baseplate means, whereby a straight line will pass through the longitudinal axes of said second spindle means, said separation roller means and said wiper roller means prior to a dispensing operation.
