  • Patent number: 6772749
    Abstract: A band saw with a complex coordination of a tilting motion and a translational motion between the workpiece and the band saw blade, so that a curved cut is made in the workpiece. The geometric parameters of the cut can be continuously adjusted. This makes it possible to optimize a contact length of the saw blade in the workpiece, which is an important factor in the cutting process. It is thus possible to saw workpieces made of stone and similar materials that are typically difficult to cut. The cut and the contact length of the saw blade can be tailored individually to each workpiece to be sawed. Thus, workpieces of different geometrical dimensions and different material properties, in particular with different material hardnesses, can be processed using the band saw according to the invention without having to undertake significant changes.

  • Patent number: 6601493
    Abstract: A fence system for a band saw. The band saw defines an actual cutting plane and has a table having a table surface defining a desired cutting plane. The fence system comprises a rail member, a base member, a locking assembly, a fence member defining a fence surface, and an adjustment system. The rail member is mounted on the table and defines a rail axis that is substantially perpendicular to the desired cutting plane. The base member is supported by the rail member. The locking assembly selectively locks the base member at a selected position along the rail axis. The adjustment system mounts the fence member to the base member at a selected angle relative to the rail axis. The base member defines a pivot point about which the fence member is rotated by the adjustment system, and the pivot point is adjacent to the rail member.

  • Patent number: 6267037
    Abstract: An underwater apparatus for servicing subsea pipelines provides a telescoping frame which can be lowered to the vicinity of the pipeline. The frame has an open section so that it can straddle the pipeline and outer jacket and fixate itself releasably so that it can be selectively repositioned. A cutting apparatus is secured to a telescoping sub frame. The cutting structure can be rotated about the longitudinal axis of the sub frame, as well as advanced along the direction of the longitudinal axis of the frame due to the telescoping feature of the sub frame. The cutting structure can also be moved pivotally about an axis of rotation which is outside and generally perpendicular to the longitudinal axis of the pipe. Thus, combining the telescoping feature with the pivoting feature and the feature of being able to rotate about the longitudinal axis, a variety of different cuts can be made.
