The invention provides a method of providing a tapered edge on a sheet comprising a fibrous material, comprising moving the sheet while carrying out the following steps: moving the sheet past a freezing device, which sheet is provided with a substance embedding the fibrous material, at least at a first edge of the sheet, which substance is in a non-solid state at room temperature, in particular at 20 degrees Celsius, and cooling the first edge using the freezing device, so that the substance at the first edge becomes solid, moving the sheet past a machining device while the substance is solid from the cooling using the freezing device, and machining, during the step of moving the sheet past a machining device, the first edge with the machining device to provide a first tapered edge.

A method of machining a fibrous sheet for a composite structure is described. The sheet comprises a resin matrix having a glass transition temperature, wherein the method comprises cooling the sheet substantially to maintain the temperature of the matrix below its glass transition temperature during machining.

With the machine, workpieces are machined as they pass through the machine. At least one of the spindles of the machine is coupled with an adjusting unit with which the spindle, for producing a contour on the workpiece, can be adjusted transverse to the throughfeed direction of the workpiece during workpiece throughfeed. The adjustment of the adjusting unit is realized as a function of the advancing speed of the workpiece and/or the workpiece position upon throughfeed of the workpiece. The adjusting unit has such a stiffness and/or low clearance and/or positioning precision that the end products machined from the workpieces after exiting from the machine can be used without further post-machining. The end products have such a geometry precision and surface quality that further post-machining is no longer required.

The smooth finish tool corrects pipe ends that need to be perpendicular to its length. A cylindrical guide wall has an open and closed end. The guide wall envelopes the pipe end. An abrasive surface, such as a sanding disc, is affixed to the closed end of the guide wall. The guide wall has a port or ports to allow material discard and air flow. Because of the rotational speed, friction and resultant heat will be created so air flow is necessary to prevent excess heat buildup. Since the guide wall will be dependent on the size of the pipe the user is sanding, the guide provides a stable applied-force angle. A shaft, such as an arbor, may allow for variably sized tool attachments. Once done finishing simply remove the guide from the pipe.
