ABSTRACT:
A tool for manually dispensing and applying a web of elongated flexible stock material such as a plastic stretch film from a roll of the stock material having a shaft that supports the roll. The tool includes a flexible gripper having a cylindrically shaped body defining an open center, an open upper end and a closed lower end, and a relatively rigid cylindrical sleeve having a hollow center received in the open center and having a length less than the length of the gripper. This assembly has a gripping surface so that the operator can grip the shaft and hold it tightly without affecting the braking force on the shaft. The operator can compress the upper portion of the gripper inwardly onto the shaft when the gripper and cylindrical sleeve are mounted on the shaft, creating a braking mechanism that slows or stops the rotation of the shaft and at the same time apply a differential pressure to the roll to firmly hold the roll as strongly as necessary.
