Abstract
An object of the invention is achieved by a method for cutting an elongated shell-type object. The method may include steps of providing a gantry defining a portal and comprising a wire grid operable in the portal; operating the wire grid, whilst moving the shell-type object through the wire grid along a lateral-axis (Z) substantially perpendicular to the portal. The method is performed by a stationary gantry, where the shell-type object is moved through the portal. Thereby, the method is simplified as there is no need for a rail system for moving the gantry.
Claims12
A method for cutting an elongated shell-type object being a wind turbine blade, an aero-plane hull, a vessel hull, glass fiber reinforced container, a tank, a vessel, or a pipe, the method comprises the following steps:
- providing a gantry that defines a portal, the gantry including a wire grid operable in the portal, the wire grid comprises several cutter wires and the step of providing the gantry includes attaching a sled comprising a sled support to the shell-type object at a distal point relative to the gantry and a pull system having one or more cables extending between the sled and the gantry;
- operating the wire grid;
- whilst
- moving the shell-type object through the wire grid along a lateral-axis substantially perpendicular to the portal by pulling the sled towards the gantry by pulling the one or more cables as a function of the position of the distal point of the shell-type object;
- and
- determining a strain on the wire grid to prevent breakage of the several cutter wires, wherein the step of pulling the sled and the shell-type object is performed as a function of the strain.

- and
- determining a strain on the several cutter wires, wherein the step of operating the wire grid is performed as a function of the strain to prevent breakage of the several cutter wires.
A cutter system configured for cutting an elongated shell-type object being a wind turbine blade, an aero-plane hull, a vessel hull, glass fiber reinforced container, a tank, a vessel, or a pipe, the cutter system comprising:
- a gantry defining a portal, the gantry having a front side configured and arranged for facing the elongated shell-type object,
- several cutter wires extending in the portal, thereby defining a wire grid,
- a wire drive configured for driving the one or more cutter wires,
- a sled comprising a sled support configured for supporting the shell-type object and for moving the shell-type object through the portal;
- and
- a pull system having one or more cables extending between the sled and the gantry;
- a controller, wherein the moving means is configured and arranged to be operated by the controller, and the controller is configured to determine a strain on the cutter wires and to pull the sled towards the gantry as a function of the strain to prevent breakage of the several cutter wires.
