  • Patent number: 10543567
    Abstract: A method of manufacturing a strip of rubber having discontinuous reinforcer segments includes a conveying step in which a rubber strip is conveyed in a direction DC, and a cutting step in which reinforcers of the strip are cut. The cutting step includes localized heating of each reinforcer using a laser beam from a remote source. A cutting device useable to perform the cutting step includes a conveying device and a cutting head. The conveying device moves the strip in the conveying direction DC past the cutting head. The cutting head includes an emitter from which at least one laser beam is produced to cause localized heating of at least one reinforcer of the strip, in order to cut the at least one reinforcer into discontinuous reinforcer segments. The strip may be conveyed continuously or discontinuously, such that the strip may be moving or immobilized during the cutting step.

  • Patent number: 10413968
    Abstract: The machine presents a working zone that is defined in an upper part of a build sleeve which is fixedly mounted in a chassis. Within the working zone, the object is supported by a build plate which slides inside the build sleeve when driven in vertical translation by the head of an actuating cylinder which is placed along a central axis of the sleeve. The build plate is positioned inside a transport container which is arranged removably between the sleeve and the actuating cylinder. The machine also includes a means for moving the transport container vertically into contact with the build sleeve. The container is open at its top and at its bottom so that, when the actuating cylinder is actuated, the head thereof can transfer the plate between the transport container and the build sleeve which forms a build envelope around the plate.

  • Patent number: 10343215
    Abstract: The machine is of the type which uses an energy beam which acts on a powder layer in a working zone. The machine has a device for layering said powder and which includes a means for storing powder, a means for distributing powder, a feeding means that transfers powder from the storage means to the distributing means, and a metering means that controls the quantity of powder transferred from storage means to distributing means. The storage means is positioned higher than the working zone, the feeding means utilizes gravity, and in use, the feeding means and the metering means move with the distributing means. The machine has two separate working zones and two separate working trays that move independently of one another. Each of the working trays is associated with only one working zone, and the layering device is common to both working zones.
