Embodiments provide a pre-cut infeed system for a machine center, such as an edger. A pre-cut infeed system may include an infeed, one or more saws arranged along the infeed, and a scanner optimizer system. The scanner optimizer system may scan a workpiece and determine whether greater value can be obtained from the workpiece by cutting the workpiece transversely into two or more pieces upstream of the machine center. If so, the workpiece may be cut transversely by the saw(s) positioned along the infeed, and the cut pieces may be fed sequentially into the machine center.

One or more ram accelerator devices may be used to form one or more holes in geologic or other material. These holes may be used for drilling, tunnel boring, excavation, and so forth. The ram accelerator devices propel projectiles which are accelerated by combustion of one or more combustible gasses in a ram effect to reach velocities exceeding 500 meters per second.

A method and a device for trimming printed products on the front edges and/or on the lateral edges. The products are inserted into moved receiving compartments along a closed circuit, the compartments being open on at least one side, and include blades moved along in this region, which act together with stationary counter blades. The depth of insertion of the products is restricted by a support such that the front edges of the products are in the direct vicinity of the open side of the compartments, advantageously protruding with their front edges over the moved along blades for the frontal trimming. The edges of the products extending perpendicular to the folded edge are fixed prior to carrying out a trimming by way of a clamping and moving arrangement and only released for the passing on of the printed product.

A media cutting system is disclosed comprising a die cutter including a cutting surface and a plurality of dies stored proximate the cutting surface, a die exchange system including a die storage system configured to support the plurality of dies and a die transport system, and a computer system comprising a controller configured to operate the die transport system and the die cutter. A die exchange system and methods of making and using the die exchange system also are disclosed.

Building panels provided with a locking system for vertical and horizontal locking of a first edge and a second edge of adjacent panels. The locking system includes a displaceable tongue at least partly arranged in a displacement groove, a tongue groove, a cavity provided in a strip at the first edge, and a protrusion extending downwards at the second edge. The displaceable tongue is arranged to be displaced at least partly into the tongue groove during locking, and wherein the protrusion is arranged to be located in least a portion of the cavity when the panels are locked vertically and horizontally.

A cutting apparatus for cutting corner pieces formed of stone or other materials for use as building faces or for cutting flat pieces is disclosed herein. The cutting apparatus includes a frame with a first and a second conveyor operatively attached to the frame. The first and the second conveyors are configured to carry a workpiece from a first end of the frame to the second end of the frame. The first conveyor is disposed at an angle of about 45 degrees to a ground surface supporting the cutting apparatus. The second conveyor is disposed at an angle of about 45 degrees to the ground surface supporting the cutting apparatus, wherein the second conveyor is positioned perpendicularly to the first conveyor so as to form a V-shaped channel therewith. The cutting apparatus further includes a first cutting blade operatively attached to the frame and positioned generally parallel to the first conveyor and a second cutting blade operatively attached to the frame and positioned generally parallel to the second conveyor.
