Abstract:
1. A rotating log saw clamp for clamping a product roll to be sawn, the rotating log saw clamp comprising: clamping structure positionable about an axis for clamping a product roll; a first portion adapted to receive the product roll therethrough, the first portion mounted concentrically with the axis and being selectively continuously rotatable in a first direction about the axis, the first portion adapted to move the clamping structure for selectively clamping and unclamping the product roll within the first portion; and a second portion adapted to receive the product roll therethrough, the second portion being mounted concentrically with the axis for selective continuous rotation about the axis in the first direction with the first portion and cooperatively drivingly connected to the first portion to be selectively movable about the axis relative to the first portion to move the clamping structure between open and clamping positions, the first portion and the second portion each being positively driven to cause the second portion to be rotatable relative to the first portion about the axis to move the clamping structure from the clamping position to the open position to unclamp the product roll and to move the clamping structure from the open position to the clamping position to clamp the product roll as a result of the cooperative drivable connection and relative rotation of the second portion with respect to the first portion during rotation of the first portion and the second portion in the first direction.
