发明名称 Lock shaft for paper cores
摘要 A material transfer system is disclosed using a hollow cylindrical lock shaft for rewinding flexible material from an original core to at least one transfer core. The shaft has an interior and exterior wall, a length, and at least one curved locking base recessed along the length. The bases have a first and second wall with a floor having a progressively decreasing radius from the first to the second wall. Multiple legs extend radially inwardly from the interior wall and have gripping feet are at their distal ends. A plurality of locking ribs extend the length of the locking bases and are affixed to the floor at the each end of the rib. The locking ribs have a diameter sufficient to enable the locking rib outer circumference to extend beyond the circumference of the shaft exterior. At least one locking strip is affixed to at least a portion of the shaft's length, extending beyond the circumference of the exterior wall to prevent the cores from moving freely. The locking strip can be affixed to the locking base floor or a channel can be placed in the shaft and the locking strip being affixed within the channel.
