Abstract:
A method for recovering material from consumed accumulator batteries consists of providing a rotatable table, keeping the table under continuous rotation, continuously feeding a row of batteries tangentially to the periphery of the table in such a manner as to bring one of the side walls of the casing of each battery into contact with the table periphery such that a portion of said side wall projects below the table contour, exerting a radial thrust on that side wall of each battery casing which is opposite the wall in contact with the table periphery such as to keep said battery adhering to said table over a path corresponding to a substantial angle of rotation of the table, separating the lower horizontal wall of the respective casing from each battery by a cutting action carried out on that part of each battery which projects below the table contour while the battery is adhering to the table, so as to enable said wall to be separated from the remaining part of the battery by gravity, and then releasing the radial thrust exerted on each battery at the end of said path so as to enable the table to be separated from said remaining part of the battery by gravity.The invention also relates to a machine for carrying out the method.
Abstract:
In the slitting of a web of material such as aluminum by passage of the web over at least one pair of symmetrically-arranged circular knives and respective counterknives to excise a narrow waste strip from two between newly formed sub-webs, the improvement which comprises temporarily and elastically deforming said circular knives over a portion of their peripheries downstream of their points of cut whereby said knives at such portions will be prevented from contacting the edges of said subwebs. To this end, in an apparatus as described a pair of rotatable wheels are resiliently urged against said circular knives just downstream of the points where the knives disengage the counterknives.
Abstract:
This invention is directed to a method and apparatus to automatically increase the pressure on the cutting blade of a score cutter upon the detection of an area of increased thickness in the material approaching the cutter to be cut.
Abstract:
The bidirectional sheet metal cutting tool (100) is a cutting tool that performs cuts on webbed material in which a length of cut exceeds a physical dimension of the cutting tool (100), while limiting flexing of the webbed material during a cutting operation. The cutter assembly (140) is configured to ride on a guide track (145), and has upper and lower sections. The upper and lower sections have an offset attachment to each other at an interface, so that the webbed material passes the offset after cutting in an extended bypass cutting operation. An interface between the upper and lower sections has a curved profile, allowing deflection of the webbed material on at least one side of a cutting direction. The cutting tool (100) can be mounted to a sheet metal forming tool as a slitter (500), permitting sequential operations of the metal forming tool.
Abstract:
This application relates to a device for cutting sheet metal to provide a positive coupling between the cutting clearance and the immersion depth. The device includes a first circular blade having a first blade edge and a second circular blade having a second blade edge. The sheet metal to be cut is located between the first and the second circular blades during cutting. The first circular blade is rotatably mounted about a first axis of rotation and the second circular blade is rotatably mounted about a second axis of rotation which runs parallel to the first axis of rotation. A relative position of the first circular blade relative to the second circular blade can be adjusted. A distance between the first circular blade and the second circular blade is defined by a cutting clearance by which the first blade edge is axially spaced apart from the second blade edge in the direction of the first axis of rotation, and by an immersion depth by which the first blade edge and the second blade edge radially overlap each another in a direction perpendicular to the axes of rotation.
Abstract:
A cutter for cutting a formed gutter discharged from a seamless gutter machine. The cutter may be positioned to cut a back wall of a formed gutter below a front upper edge of a front wall of the gutter. In turn, a gutter may be mounted to a building (e.g., a fascia board thereof) to achieve additional lift, thereby providing increased pitch over a given length of gutter while maintaining overlap between a gutter apron and a back upper edge of the back wall of the formed gutter.
Abstract:
A machine for slitting metal sheet into strips includes a fixed upper beam and a lower beam that is displaceable vertically. Both beams support slitter heads that move along the beams. Each beam carries an arbor that rotates in it and extends through the slitter heads on it. Each beam also has a fixed threaded shaft and lock rods that extend through the slitter heads on it. Each slitter head carries a ring-like knife that rotates with the arbor for its beam. Each slitter head also has a motor-driven nut that engages the threaded shaft extending through the beam and, when rotated, moves the slitter head along its beam. The slitter heads have clamps, which clamp down on the lock rods to secure the slitter heads in fixed positions. The knives rotate about axes that are skewed slightly relative to the axes of the arbors that drive them.
Abstract:
A longitudinal cutting machine having an upper blade held and displaceable on a first longitudinal guide, and a lower blade that is associated with the upper blade, the lower blade being held on and displaceable along a second longitudinal guide. A displacement device is associated with one of the lower blade or upper blade, and is provided with an extendable driving rod that bridges a gap to that longitudinal guide that holds the other of the upper blade and lower blade. The driving rod acts on the other blade such that the displacement device displaces the upper blade and lower blade together. A guide mechanism is disposed on the driving rod and acts on that longitudinal guide that holds the other of the upper blade and lower blade.
