Patent number: 6035749Abstract: A method and apparatus by which selected pile across the face of a web of pile fabric such as carpet may be raised or lowered in accordance with a pattern as the fabric passes through shearing apparatus so that certain pile of the pile may be sheared more than other pile to provide a sculptured affect. Nozzles extend across the width of the fabric and apply jets of air from controllable valves to impinge on the pile in its path to compress or raise selected pile in accordance with a pattern controller which controls the valves. Locating the nozzles so that jets of air impinge on the pile upstream from the shearing apparatus in a direction downstream toward the shearing apparatus will raise the pile while locating the nozzles so that the jets of air impinge upon the pile prior to the shearing location in an upstream direction will compress the pile. The pile which is raised is cut further than pile which is not raised and cut even further than the pile that is compressed.Type: GrantFiled: July 22, 1997Date of Patent: March 14, 2000Inventor: Jack G. Haselwander

Patent number: 5992281Abstract: An apparatus for scarfing edge portions of a veneer sheet to produce a joint suited for joining the veneer sheets in an edge to edge relation. A conveyor system aligns, conveys and flattens the sheet. The sheet as it is being conveyed is engaged by tapered anvils that deflect edge portions of the sheet at an angle to the plane of the flattened sheet. One anvil on one side deflects one edge portion upward and the anvil on the opposite side deflects the opposite edge portion downward. The resiliency of the sheet maintains the deflect edge portion against the anvil. The sheet is conveyed through scarfing saws which generate a bevel on each of the deflected side edges.Type: GrantFiled: February 19, 1997Date of Patent: November 30, 1999Assignee: Corvallis Tool Co.Inventor: John C. Holbert

Patent number: 5520241Abstract: The machine for removing burrs from slabs (1) issuing from a continuous casting installation and cut to the desired length by oxygen cutting, is of the type comprising a rotor (10) carrying on its periphery self-retractable hammers (11). The rotor (10) comprises a hub (12) on which are fixed, at each end, an end flange (13) in the form of a circular collar and, between these two end flanges (13), pairs (14) of semi-flanges (15) which are in the form of semi-circular collars and are adjacent and opposed. Each pair (14) of semi-flanges (15) is evenly spaced apart in the longitudinal direction of the hub (12) and one of the semi-flanges (15) of each pair (14) is offset in this longitudinal direction relative to the other of the semi-flanges (15) of this pair (14). The invention also provides a rotor employed in this type of burr-removing machine.Type: GrantFiled: October 26, 1994Date of Patent: May 28, 1996Assignee: SollacInventors: Jacques Meunier, Francis Coppin, Dominique Duval

Patent number: 5165151Abstract: This invention provides a shearing apparatus for shearing, between a spiral cutter and a lower blade, tip ends of numerous piles formed on a foundation of a pile fabic. The shearing apparatus has a construction for producing fine design patterns, and comprises a plurality of elements each including a thin main body vertically movably mounted in a slit defined in an element block, and a thick head formed integral with the thin main body for pressing the foundation toward the spiral cutter. The thick heads of the elements are arranged close to one another without gaps in between over an entire axial length of the spiral cutter. Each of the elements further includes a leg formed integral with a lower portion of the thin main body to be offset from legs of adjacent elements. A cylinder mounting block disposed below the element block has piston rods of air cylinders arranged in positions opposed to the respective legs.Type: GrantFiled: March 25, 1992Date of Patent: November 24, 1992Inventor: Chieko Nakagawa

Patent number: 4997323Abstract: Resilient tile within 0.005 inches of square and having sides within 0.005 inches of each other may be produced by positioning unfinished tile on a continuous belt. One edge adjacent the trailing edge of each tile is made to contact a stop means while the trailing edge is made to contact two independently adjustable dogs on the continuous belt. The tile is held down by hold-down rollers while the tile is so positioned. The two edges adjacent the trailing edge are edge finished, preferably by two cylindrical shaper routers. The tile is then positioned on a second continuous belt with one of the finished edges becoming the trailing edge and the remaining two edges being edge finished.Type: GrantFiled: June 22, 1989Date of Patent: March 5, 1991Assignee: Armstrong World Industries, Inc.Inventors: Joseph L. Giandalia, Darryl L. Sensenig

Patent number: 4978259Abstract: A device for on-line deburring of metal strip advancing continuously along a defined path, including a rotary knife having an inwardly facing cutting edge, and structure supporting the knife for rotation such that the cutting edge engages and shaves burr from a strip edge at a location beyond the axis of knife rotation, in the direction of strip advance. In a deburring method using such a knife, the knife is rotated by its engagement with the strip edge, in such direction as to throw the shaved burr laterally outwardly away from the strip.Type: GrantFiled: May 4, 1988Date of Patent: December 18, 1990Assignee: Alcan International LimitedInventor: Carl A. Wollam

Patent number: 4976573Abstract: An apparatus for chamfering the outer edges of stacked printed circuit boards comprises a detecting device for detecting the boundary between two adjacent boards, and a chamfering tool positionable adjacent to the opposed outer edges of respective ones of the two adjacent boards in response to detection of the boundary and movable along the board outer edges to simultaneously chamfer both outer edges. The chamfering tool successively chamfers pairs of opposed outer edges in the upward direction on one side of the stack, and then the stack is turned so that the chamfering tool chamfers the outer edges on a different side of the stack printed circuit boards.Type: GrantFiled: January 3, 1989Date of Patent: December 11, 1990Assignee: Nippon CMK, Corp.Inventors: Kamehru Seki, Isamu Kubo
