A rotating tool pot chain is capable of bending in both directions, the tool pot sweeps a relatively small area as it rotates, and the chain is capable of holding the tool pot stably. A pair of inner link plates (23) and a pair of outer link plates (24), are formed with openings to provide tool pot storage areas (23a, 24a) so that the tool pot, when stored, is parallel direction with the adjacent link connection pins 26. The center of each tool pot storage area (23a, 24a) is located on a chain pitch line passing through the centers of the adjacent connection pins 26. Further, the fulcrum (support pin 50) on which the tool pot 42 rotates is below the level of the adjacent connection pins 26 but above the bottoms of the tool pot storage areas (23a, 24a).
A rotating tool pot chain having tool pots attached to and carried by a chain, wherein the chain comprises pairs of inner link plates and pairs of outer link plates arranged alternately along the length of the chain, and connection pins articulably connecting the pairs of inner link plates with the pairs of outer link plates, each said pair of inner link plates and each said pair of outer link plates having an opening, the openings in the link plates of each said pair of link plates forming tool pot receiving and storage areas, and a fulcrum connecting each said tool pot to a link plate of a pair of said link plates for rotation of the tool pot about an axis parallel to the length of the chain, wherein each said tool pot has a center, and the storage areas are positioned so that, when the tool pots are received in the storage areas, the centers of the tool pots are aligned with the connection pins along a chain pitch line at a level passing through the centers of said connection pins.
