A multilayered sheet assembly for forming a sign on an object includes a carrier layer including a first side and a second side, a sign layer that is arranged on the first side of the carrier layer via a first adhesive layer, and a strip layer that is arranged on the second side of the carrier layer via a second adhesive layer in an adhesively separable manner. The sign layer carries a third adhesive layer at an exposed side that is across from the carrier layer to allow a sign that is formed by the sign layer to adhere to the object at the exposed side while releasing from the carrier layer.

A cutting machine can be configured to set a cutting line with respect to a cutting material that is placed on a supporting platform, cut the cutting material along one cutting line that intersect with and changes direction at a second cutting line at a corner portion, leaving a part of the cutting material connected along a predetermined distance from a point of intersection of the corner portion, and cutting along the other cutting line so as to not leave a connected part, up to a predetermined distance from the point of intersection of the corner portion.

The invention relates to a system made of an electronic display device having a display screen for displaying augmented reality, an electronic memory, and a cutting device for cutting planar cutting stock, e.g., paperboard, corrugated cardboard, film, textile, plastic, foam, or wooden slabs or sheets. The system has a computer unit for computing a position and alignment of the display device in relation to the cutting device. The display device is designed to be worn by a user and positioned in the field of vision of the user. The system is designed to display to the user retrieved cutting-stock-related information by means of the display screen in a manner readable by the user in the field of vision of the user, adapted to the position and alignment of the display device in relation to the cutting device, and linked to an actual and/or setpoint position of the cutting stock.

A multilayered sheet assembly includes a carrier layer on which a sign layer is arranged on a first side via a first adhesive layer. The sheet assembly further includes a strip layer which is arranged via a second adhesive layer in adhesively separable manner on a second side of the carrier layer. A further includes arranging the multilayered sheet assembly on a cutting device, arranging a peripheral cut in the sheet assembly along an outer periphery of a sign, arranging an inner cut in the sheet assembly along a peripheral line of at least one enclosed surface area not forming part of the sign, separating the strip layer with adhesive retention of the at least one enclosed surface area not forming part of the sign, and separating the sign layer from the carrier layer.

A cutting machine having a table with a working surface is disclosed. The working surface including a crossbeam above the working surface configured to be linearly positioned parallel to a first horizontal axis, a module, mounted on the crossbeam configure to be positioned parallel to a second horizontal axis, which extends perpendicularly to the first horizontal axis, a tool holder mounted in the module configured to move in a vertical axis and rotate about the vertical axis, and to accept one of a plurality of different interchangeable tools, and a control unit, wherein the tool holder has a connection device designed to supply the tool with power and a fluid, wherein the supply with the fluid is provided via a rotary joint, and wherein the power is provide via a rotary transmitter.

A cutting machine having a work surface, configured to accommodate at least one object to be cut, a working group, which is movable above the work surface including a receptacle device for accommodating a replaceable cutting tool, and a processing unit for controlling the cutting machine and storage capacity for providing a database, characterized by a first sensor unit, which is designed to detect individual items of identification information of the cutting tool and to provide detected items of identification information to the processing unit, wherein the processing unit is designed to recognize the cutting tool based on the items of identification information, to detect operating data of the cutting tool and store these data in the database, wherein the operating data comprise at least one operating time of the cutting tool, and to carry out operational monitoring of the cutting tool based on the operating data.

To provide a manufacturing method for a composite material, a manufacturing apparatus for a composite material, a preform, and a composite material, capable of molding a high quality composite material having a little constraint in the shape by improving moldability while suppressing a deviation of the arrangement of the reinforced fiber during preforming. A manufacturing method for a composite material 400 provided with a reinforcement 510 and resin 600 infused into the reinforcement, includes: an apply process (step S12) for applying an adhesive to the sheet-shaped reinforcement having first and second regions 511 and 512 such that a content density of the adhesive 520 of the second region is lower than that of the first region; and a preforming process (step S17) for preforming the reinforcement in a three-dimensional shape to form a preform such that the second region has a curvature larger than that of the first region.

Methods of trimming fiber reinforced polymer composite workpieces are provided which use a pure waterjet discharged from a cutting head in liquid phase unladened with solid particles at an operating pressure of at least 60,000 psi and in combination with other cutting parameters to provide a final component profile without delamination, splintering, fraying or unacceptable fiber pullout or fiber fracture.

A method is provided for automatically modifying the cutting paths for parts to be cut out from a flexible material by automatically moving a cutter tool along predetermined cutting paths. The cutting paths are associated with each part being defined by a succession of cutting segments forming a polygon. Two cutting segments are identified and belonging to two different parts for cutting out in the material and for which a maximum distance condition between these cutting segments is satisfied. Two cutting segments are verified for being situated facing each other, and that no other cutting segments lie between the two cutting segments. A common cutting path for the two cutting segments is computed, and a common cutting path is connected to the cutting paths of the two parts for cutting out to obtain modified cutting paths for the two parts for cutting out.
