Abstract
A tension reel for strip coiling which includes a continuous double expansible mandrel rotatably supported at opposite ends to a frame. The double expansible mandrel consists of two expansible mandrel sections joined endwise in axially separable drive engagement such that rotation of one mandrel section for strip coiling also drives the other mandrel section when they are axially joined in driving engagement. Means are provided to axially engage and retract the mandrel sections relative to each other to remove the coiled strip from between the divided and collapsed mandrel sections.
