Apparatus for forming a loop of strap about a package in which the strap is initially draped about the package in spaced relationship therefrom. Included is a clamping bar assembly which includes a package engaging member and a pair of spaced catch blocks over which the strap is draped. The catch blocks are rotatably mounted relative to the clamp bar assembly and are operated through the action of rack and pinion assemblies that respond to the movement of the package engaging member. When the package is engaged, the catch blocks release the strap normally guided thereby and when the clamp bar is retracted, the catch blocks are repositioned to guide a subsequent loop of strap.
