A theater rigging assembly having a beam, which is attached to structural support members of a theater or other performing arts venue. The assembly further includes a winch assembly and head block that can be positioned at any point along the beam and selectively fixed in position. The winch portion includes cables for raising and lowering battens or other loads. The head block includes head sheaves, which redirect the cables to loft sheaves that are selectively attached to the beam. The head sheaves are diagonally displaced to separate the cables. The winch portion includes a motor, a gear box, a drum and a brake. The brake includes a ratchet and two brake disks. It uses at least one friction surface that contacts at least one of the brake disks to cause a pawl to engage or disengage from the ratchet.

Theater rigging system

A turret winder for winding web material on spindle-supported cores has a turret which is moveable into three indexing positions, one of which is a web transfer, cutting and winding station, and another of which is a winding completion station. Frames adjacent to the turret support carriages which support a secondary lay-on roll. The carriages include a primary carriage which is moveable vertically with respect to the turret and a lay-on roll carriage which is moveable horizontally with respect to the primary carriage. The lay-on roll carriage has an arm which is engaged by the turret during movement of the spindle between the above two positions so that arcuate movement of the spindle is translated to movement of the lay-on roll carriage in such a manner that the lay-on roll accurately follows the movement as the building roll moves to the winding completion station.
