Abstract
A rotating saw clamp for clamping a product roll to be sawn. The rotating log saw clamp includes a first portion disposed for rotation about an axis and a second portion disposed for rotation with the first portion and movable relative to the first portion between an open position and a clamping position. The second portion is rotatable from the clamping position to the open position in rotation of the first and second rotating portions in a common direction.

A rotating saw clamp for clamping a product roll to be sawn, the rotating log saw clamp comprising:
- a first portion disposed for rotation about an axis;
- and
- a second portion disposed for rotation with the first portion and movable relative to the first portion between an open position and a clamping position, the second portion being rotatable from the clamping position to the open position in rotation of the first and second rotating portions in a common direction.
A method of clamping a product roll to be sawn in a rotating log saw, the method comprising:
- rotating first and second portions in a common direction about an axis;
- and
- rotating the second portion relative to the first portion to move the second portion from a clamping position to an open position during rotation of the first and second rotating portions in a common direction.
A rotating saw clamp for clamping a product roll to be sawn, the rotating log saw clamp comprising:
- a first ring adapted to clamp and rotate about an axis a product roll to be sawn;
- and
- a second ring rotatably coupled to the first ring, the second ring driven separately from the first ring for rotation relative to the first ring as the first and second rings rotate together in a common direction, the second ring being rotated relative to the first ring to adjust the clamping of the product roll.
A method of clamping a product roll to be sawn in a rotating log saw clamp, the method comprising:
- rotating first and second rings in a common direction about an axis;
- driving the second ring separately from the first ring for rotation relative to the first ring during rotation of the first and second rings together in a common direction;
- and
- adjusting the clamping of the product roll.
A rotating saw clamp for clamping a product roll to be sawn, the rotating log saw clamp comprising:
- a frame;
- a housing rotatably coupled to the frame about an axis, the housing disposed for rotation with a product roll to be sawn;
- a plurality of clamps positioned about the axis and movable relative to the axis;
- and
- a ring rotatably coupled to the housing about the axis, the ring rotatable independently of the housing, the ring rotatable relative to the housing in common rotation of the housing and ring, the ring being movable relative to the housing to move the plurality of clamps relative to the axis.
A method of clamping a product roll to be sawn in a rotating log saw clamp, the method comprising:
- rotating a housing and a ring in a common direction about a common axis;
- rotating of the ring independently of the rotation of the housing;
- rotating the ring relative to the housing during common rotation of the housing and ring;
- and
- moving a plurality of clamps relative to the axis by rotating the ring relative to the housing.
