  • Publication number: 20040255743
    Abstract: A discoid lower blade and a discoid upper blade, having a sharper knife angle compared with that of the lower blade, are arranged such that rotational axes thereof are parallel to each other, and portions of the blades overlap one another in the direction that the rotational axes extend. A sheet with a coating layer on one side is fed through and shear-cut between the upper and lower blades in the direction perpendicular to the rotational axes, with the surface of the sheet opposite the coating layer in contact with a periphery of the lower blade while the blades are rotated. When the sheet is shear-cut, a contact start position, where contact between the sheet and the upper blade starts, is positioned upstream in the feed direction of the sheet but outside a contacting area of the sheet, where the sheet contacts the periphery of the lower cutting blade.

  • Patent number: 6792839
    Abstract: A rotating shearing device for cropping fast-running rolling stock, in particular wire, includes two axially cutting annular knives which rotate about their axes at the same rotational speed. The two axially cutting annular knives include end cutting edges directed toward one another which converge to the clearance required for separating running stock during the cutting operation and lie in planes which are arranged at an acute angle to one another and intersect one another in a line. The rolling stock is guided toward the shearing device by a front guide and guided away from the shearing device by a rear guide. The front guide is pivotable to change in the relative position between the rolling stock and the cutting body so that the rolling stock may be guided either through the space between the annular knives which is free for the cut-free passage of the rolling stock or into the wedge-shaped cutting region of the annular knives.

  • Patent number: 5302228
    Abstract: Disclosed is an apparatus and method of fabricating tank wrap of desired thickness having fibers oriented generally in the thickness direction from lengths of insulation material having fibers oriented generally in the length direction. The method comprises several sequential steps. The first step is positioning the lengths of insulation material lengthwise along a first movable track conveyor, such that the fibers are oriented generally parallel to the direction of conveyance as the lengths progress downstream in a longitudinal direction along the conveyor. Second step is severing the insulation material completely across the length, at intervals equal to the desired thickness of the tank wrap to be fabricated. Next the cut lengths of insulation material are positioned lengthwise across a second movable track conveyor such that the fibers are now oriented generally perpendicular to the direction of conveyance, and in an abutting relationship.

  • Patent number: 5058475
    Abstract: A web slitting machine for cutting a web or roll of material includes an upper carriage assembly joined to a lower blade holder assembly by a selectively removable guide key which is milled to provide a predetermined cant angle for the blade. The blade is lowered into position by a piston which is rectangular and includes a torsion-resisting sleeve to prevent rotation of the piston about its vertical axis. A pneumatic control provides a plurality of control modes whereby the blade may be raised and lowered with or without locking the upper carriage assembly to its transverse bar and vice-versa. A unique side shift adjustment is provided whereby the blade may be shifted to a half-stroke position and the upper carriage locked when the blade is positioned against a lower knife. This ensures that the pressure of the blade against the knife is the pressure exerted at the mid point of the stroke.

    Abstract: A cutting machine to form a tenon at each end of a piece of timber, which tenon has opposite faces which are inclined both longitudinally and transversely relative to the piece of timber and form hereinafter called skew tenon faces. This tenon cutting machine is of simple and inexpensive construction and uses a pair of circular saws which are simply arranged angularly relative to each other and to the piece of timber to produce both skew tenon faces at each end of the piece of timber by simple bodily displacement of the circular saws transversely of the piece of timber. This machine includes a carriage displaceable in a predetermined direction and carrying the two circular saws, a timber carrying bench to place the piece of timber lengthwise orthogonally to this direction and laterally slanted either way in this direction. The displacement of the carriage causes the saws to cut the two surfaces respectively which are required on either side of the tenon.
