ABSTRACT:
An elongate flexible clamp mechanism defines first and second ends and is capable of assume a substantially flat configuration and is capable of being positioned in encircling relation about a cylindrical object such as a pipe. A pair of elongate flexible members such as wire cables, chains or pivotally interconnected rigid members support a plurality of substantially rigid clamping members in spaced relation along the lengths of said elongate flexible members. The clamping members are each provided with jack screws for force applying engagement with the pipe to enable alignment of adjacent pipe sections and to correct minor irregularities in pipe roundness so that adjacent pipe sections can be efficiently welded. The elongate flexible clamp mechanism is provided with first and second latch connector elements which are interconnected when the clamp mechanism is located in encircling relation about the pipe. The latch mechanism is of the cam or toggle type, enabling the clamp mechanism to be tightened about the pipe. Jack screws are also provided on each of the clamping elements to permit jacking force to be applied to the pipe for optimum pipe alignment and for correction of minor irregularities in pipe roundness.
