Abstract: A tensioning tool device includes a flexible or spring support having a spring bearing that translates a linearly applied external force at an input to linear displacement at an output of the spring bearing.

Abstract: Upstream and downstream grippers clamp to one or more seal zones on a bandolier of packaged premiums, such that the downstream gripper(s) and upstream clipper(a) are on opposite sides of a wakened separation line.

In one embodiment, the grippers clamp to the seal zones at locations offset from the bandolier axis and to one side thereof, thus causing a gradual tearing along the separation line and easier, less stressful separation.
