System and method for holding a workpiece in position for laser machining and/or welding thereof

A system for holding a workpiece in position and exposing it to laser radiation, such that: the workpiece includes a bottom surface and a top surface that are electrically insulated from each other. The system includes an electrostatic charge generating device for generating electrostatic charges on the top surface; an electrically conductive support for forming, on the bottom surface, electrostatic charges of opposite sign to those generated on the top surface; and a laser device for machining or welding. The electrostatic charge generating device is arranged to be activated before or during the laser machining or welding, such that the workpiece is held in position relative to the electrically conductive support during the machining or welding thereof.

Device for producing packaged electrode and method of producing packaged electrode

A device for producing a packaged electrode includes: a conveyance unit configured to sequentially overlay the electrode and the pair of separators from a front end side in a conveying direction while conveying the electrode and the pair of separators; a first joining chip configured to join lateral edges of the pair of separators together; at least one second joining chip positioned downstream of the first joining chip in the conveying direction and configured to join the lateral edges of the pair of separators together. Front ends of the lateral edges of the pair of separators being sequentially overlaid while being conveyed by the conveyance unit are joined together by the first joining chip positioned upstream before the front ends are conveyed to the second joining chip positioned downstream.

ELECTROSTATIC 3-D PRINTER CONTROLLING LAYER THICKNESS USING FEEDBACK LOOP TO EXPOSURE DEVICE

3-D printers include an intermediate transfer surface that transfers a layer of material to a platen each time the platen contacts the intermediate transfer surface to successively form a freestanding stack of layers of the material on the platen. A sensor detects the thickness of the layer on the platen after a fusing station fuses the layer. A feedback loop is electrically connected to the sensor and a development station (that includes a photoreceptor, a charging station providing a static charge to the photoreceptor, a laser device exposing the photoreceptor, and a development device supplying the material to the photoreceptor). The exposure device adjusts the intensity of light exposed on the photoreceptor, based on a layer thickness measurement from the sensor through the feedback loop, to control the thickness of subsequent ones of the layers transferred from the intermediate transfer surface to the freestanding stack on the platen.

Apparatus and process for packaging a product
10737811 · 2020-08-11 · ·

An apparatus for packaging a product comprises a packaging assembly to fix a film sheet to a support. The packaging assembly includes a lower tool having seats for receiving the support and an upper tool facing the lower tool and comprising a film holding plate for holding the film sheet. The film holding plate has an active surface for receiving the film sheet, where the upper and lower tools cooperating to define a packaging chamber. The packaging assembly is open to receive the film sheet in a first operating condition and is hermetically closed in a second operating condition. The film holding plate has a lateral surface extending substantially perpendicular to a plane defined by the active surface, the film holding plate comprising ejectors arranged in the lateral surface for ejecting a stream of gas substantially parallel to said plane and substantially away from a center of the active surface.

A heat-curable tape, a kit, and a method for connecting ends of an elongate belt to form an intermediate transfer members suitable for use with indirect printing systems. The kit includes an elongate belt and the heat-curable tape. The kit can include a crimping pin. The method includes using the heat curable tape to join ends of the elongate belt at a seam. A heater is used, in a printing system, for heat-curing the heat-curable tape onto the free ends of the elongate belt so as to form the intermediate transfer member.

Joining device and joining method

A joining device includes a pair of cylindrical rotors 210 and 220, holding surfaces 211 and 221 of which for holding a pair of sheet-like members 30, respectively, have a width smaller than a width of the pair of sheet-like members 30. The joining device has a conveyance unit 200 which superimposes the pair of sheet-like members sequentially while conveying the pair of sheet-like members, by rotating the pair of cylindrical rotors, and joining units (first joining units 300) which join portions of the superimposed pair of sheet-like members to each other sequentially, the portions protruding beyond the holding surfaces of the cylindrical rotors.
