A modular, pre-tensioned, self-cleaning screening panel having a frame and at least one pre-tensioned wire that is fastened to the frame.

Modular, pre-tensioned, self-cleaning screening panels

A screen has a plurality of flattened wires. The wires are arranged longitudinally in a first direction, and of those wires there are first and second flattened wires are spaced a predetermined distance from each other or contact or appear to contact each other at spaced intervals to form a polygonic spacing to form a desired screen spacing. The deviation from the desired screen spacing is equal to or less than the standard industry tolerance as established by ASTM E2016-11, table 8. A first and second polymeric support member homogenously encase, respectively, a first and second limited selected portions of the plurality of flattened wires spaced apart. There is no additional metal material in, within, or on the first or second polymeric support members, and the desired screen spacing is maintained even when the first and second polymeric support members are applied and cured.

Wire screen with flattened wire

A method of making a screen with an apparatus, the screen including a plurality of wires arranged in a patterned configuration, the apparatus including an extruder and a mold, the method including (a) longitudinally aligning the plurality of wires in the apparatus in a first direction only and arranging the wires in the patterned configuration, (b) applying a first bead of molten material on the wires via the extruder, and (c) directly molding the first bead of molten material into a support member for the screen by closing the mold about the bead, wherein the support member at least partially encases at least one of the wires.

Apparatus and method for making wire screen

A system and method for measuring the size, shape and distribution of particles wherein a digital image analysis based optical system characterizes the particle size distribution of granular and cohesion-less materials. The size and shape information is obtained in real time. Such an automated analysis system comprises the following four major components: 1) particle sizing hardware and software, 2) progressive scan CCD camera and stepper motor driven optical zoom system with large magnification ratio, 3) horizontal vibrating feeder, and 4) appropriate lighting system. In operation, the vibratory feeder allows the tested material free fall in front of the CCD camera. The backlight provided by a DC lighting system projects the free falling particles onto the camera's image plane. Pictures from free falling material are captured and transferred into the computer through a video frame grabber. The number of particles in each image is counted using specified intensity threshold and the size and shape of each particle is measured according to the calibration.

Particle size and shape distribution analyzer

A system and method for performing operations such as cutting on sheet material such as cloth wherein the sheet material is scanned at an inspection station to determine the existence and location of flaws in the material, the material is transferred to a conveyor where operations such as cutting are performed on the sheet material as it is moved by the conveyor, and the speed of the conveyor and the speed, direction and mode of the operations are controlled all according to a predetermined pattern of operation for the sheet material and the pattern can be re-nested or adjusted in accordance with the existence and location of flaws in the material as determined by the scanning. The operations are performed by controlled gantry-style cutters, and preferably two such cutters are employed wherein a control determines the conveyor speed and determines the portions of the cutting operation to be performed by the respective cutters.

Continuous system and method for cutting sheet material

A method and apparatus for perforating sheet material wherein the resulting perforations are in a predetermined pattern which avoids imparting structural weakness to the perforated sheet material. The predetermined pattern includes spaced perforations along linear paths which are spaced along one linear dimension of the sheet material and each of which paths is disposed at an acute angle relative to another linear dimension of the sheet material. The predetermined pattern avoids straight paths of perforations along the longer linear dimension of the sheet material and thereby avoids imparting structural weakness to the material. Preferably the predetermined pattern is a series of herringbone patterns along the longitudinal dimension of the sheet with the rows of herringbone patterns and peaks thereof extending laterally of the sheet material. The pattern is formed by moving the sheet material in a first direction and scanning the material in a second direction with a pulsed laser beam. The perforated sheet material can be used as a conveyor belt in a vacuum/suction hold-down conveyor.
