Abstract
Apparatus for handling elongate flexible material, particularly collapsible plastics irrigation piping is disclosed comprising a frame, a reel rotatably mounted to the frame, and means on the frame for driving the reel at variable speed. A guide roller is attached to the frame to be movable with respect to the reel under the action of tension in the material which, in operation, extends from the ground, around the roller and onto the reel. Means are provided responsive to the movement of the roller relative to the reel for varying the speed of the reel, thereby to maintain the tension on the material within predetermined limits.
