The herein disclosed manufacturing method of the electrode plate includes a core body exposed area cutting step for cutting a negative electrode core body exposed area with a laser, on which a negative electrode core body is exposed while a negative electrode active material layer is not provided, so as to form a negative electrode tab. Then, regarding the herein disclosed manufacturing method of the electrode plate, the negative electrode core body includes a first surface and a second surface whose surface roughness is smaller than the first surface, and the laser is irradiated to the first surface. By doing this, it is possible to suppress the sputters from sticking to the second surface, and therefore it is possible to decrease the sticking number of the sputters to the negative electrode tab.

20170364059 · 2017-12-21 ·

A method and associated system are provided for producing a perforation line between adjacent lottery tickets in an automated production line wherein a substrate having lottery tickets printed thereon is conveyed through a perforation station in the production line. A perforation machine in the line is controlled to define a perforation line between the adjacent lottery tickets. The controlling process includes inputting control variables into a controller associated with the perforation machine, the control variables relating to conditions that determine a desired perforation profile of the perforation line. The controller programs the perforation machine with a specific perforation profile for the perforation line that is generated based on the entered control variables, and changes the perforation profile upon inputting of different values for the control variables. The perforation profile is specifically tailored to the control variables between different ticket production runs, or between tickets in the same ticket production run.

20170361397 · 2017-12-21 ·

A method and associated system are provided for producing a perforation line between adjacent lottery tickets in an automated production line wherein a substrate having lottery tickets printed thereon is conveyed through a perforation station in the production line prior to being folded into a Z-fold pattern for subsequent packaging. A perforation machine in the line is controlled by a controller for defining the perforation lines, wherein the control process includes determining the perforation lines that correspond to fold lines in the Z-fold pattern and, for these perforation lines, programming the perforation machine to generate a second perforation profile that is different from a first perforation profile of non-fold perforation lines that lie between the fold lines in the Z-fold pattern. The second perforation profile is specifically tailored to produce a stronger perforation line to compensate for weakness induced in the perforation line from being folded.

Under material air purge
20170348799 · 2017-12-07 ·

An assembly and method of reducing discoloration of a foam material resulting from laser processing the material comprising an assembly configured for positioning below the material being processed and for directing air into open cells of the open-cell foam material to pressurize the material during laser processing. The assembly comprises an air delivery mechanism comprising one or more apertures for an air chamber positioned directly below the material travel path. Aligning the one or more apertures with the axis of the laser beam and its focal point when the material is positioned above the one or more apertures and pressurizing or filling of the open cells with air in the direct vicinity of the target area reduces processing related discoloration of the material. The cells are laser processed concurrently with pressurization thereby substantially reducing settling of debris and smoke on the material and reducing discoloration.

APPARATUS FOR HIGH-SPEED PROCESSING OF FABRICS

An apparatus for laser processing of very wide non-woven fabric materials at high speeds. This invention enables a laser beam to sever, perforate and pattern a large piece of fabric materials planarly disposed at regular or irregular spatial intervals over the entire width while the fabric passes from one roller to another roller at high speeds by precisely managing focus and intensity of the beam at the focal point on the web. A control system managing the laser processing system enables rapid reconfiguration of perforation patterns. The fabric can be woven or nonwoven, homogeneous or nonhomogeneous material with uniform or nonuniform thickness. An optical sensor is provided to sense the laser processing as it is performed and provide feedback to a system controller to optimize laser processing performance in real time.
