ABSTRACT:
Apparatus for forming a swimming pool cover or similar article having relatively large transverse dimensions by joining a plurality of elongated pieces of heat sealable material together is disclosed. The apparatus includes a working bed, and means for dispensing first and second pieces of heat sealable material onto the bed so that a marginal portion of the first piece is exposed. The apparatus folds the exposed marginal portion of the first piece over a corresponding marginal portion of the second piece, and the marginal portions are heat sealed together to form a single wider piece of material. The wider piece of material is drawn from the bed and stacked and then returned to the dispensing means for adding another elongate piece to the width of the material, eventually forming a piece of material sufficient to cover the entire pool.
