Abstract
Abstract A tape-clamping device for a machine for girding or stringing packages with plastic tape, the device having a clamping member rotatable toward a fixed clamping jaw, the clamping member being kept in its clamping position by self-restraint when the tape is passed between the clamping jaw and the clamping member and is moved into tape tensioning position.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
176 words
A tape-clamping device comprising: a clamping member rotatable about a shaft movable toward and away from a fixed clamping jaw, said clamping member having an arcuate tape-engaging end surface remote from and nonconcentric with the axis of said shaft; positioning means for positioning the shaft of the clamping member relative to the clamping jaw from a rest position to an operating position, the rest position being farther from the clamping jaw than the operating position, said clamping member being kept in a clamped position against the tape by selfrestraint when a length of tape is passed between the clamping jaw, and the shaft of the clamping member is moved to its operating position; means for receiving the application of a retaining force to hold said positioning means in Said operating position; and means for rotating said clamping member about said shaft; whereby upon release of said retaining force, the shaft of said clamping member is moved substantially laterally of said tape to said rest position to disengage the clamping member from the tape substantially without friction.
Claim 2
Dependent Claim
176 words
A tape-clamping device comprising: a clamping member rotatable about a shaft movable toward and away from a fixed clamping jaw, said clamping member having an arcuate tape-engaging end surface remote from and nonconcentric with the axis of said shaft; positioning means for positioning the shaft of the clamping member relative to the clamping jaw from a rest position to an operating position, the rest position being farther from the clamping jaw than the operating position, said clamping member being kept in a clamped position against the tape by selfrestraint when a length of tape is passed between the clamping jaw, and the shaft of the clamping member is moved to its operating position; means for receiving the application of a retaining force to hold said positioning means in Said operating position; and means for rotating said clamping member about said shaft; whereby upon release of said retaining force, the shaft of said clamping member is moved substantially laterally of said tape to said rest position to disengage the clamping member from the tape substantially without friction.
Claim 3
Dependent Claim
75 words
The tape-clamping device according to claim 1 wherein: said positioning means comprises a rotatable cylinder; and the shaft of the clamping member is rotatably supported eccentrically on one planar end portion of said rotatable cylinder, the other planar end of said cylinder being provided with rotating means; said rotatable cylinder is supported on rollers in a bearing bracket; and said positioning means is adapted to rotate said cylinder within a limited range of angular rotation.
