Patent number: 6692424Abstract: A rotary trimmer apparatus and signature trimming method are provided that enable operators to set a gap spacing between a rotating knife and an anvil at different predetermined sizes in an easy and accurate manner. The operator chooses the optimum knife/anvil spacing that produces a scissors-like cutting action on the particular type of signatures being trim cut and which does not cause premature knife dulling. The selected knife/anvil spacing is readily reproducable for future runs with the same operating conditions. This is true regardless of changes in the knife thickness as can be created by sharpening thereof, or knife replacement. For this purpose, a user operated control assembly including a control knob and calibrated indexer are provided. To keep the knife/anvil spacing at the set size during trim cutting operations, a temperature control system is employed that keeps axial expansion of the knife spindle shaft from reducing the gap size.Type: GrantFiled: August 1, 2001Date of Patent: February 17, 2004Assignee: Gammerler CorporationInventors: Roman G.

Patent number: 6196104Abstract: The invention relates to a method for producing sheets of polymeric surfacing, the sheets produced thereby, and the apparatus used to produce the sheets. The method includes providing a solid polymeric slab, and slicing the slab into sheets of surfacing. The sheets may include polymeric particles contained in a polymeric matrix. The particles may have a maximum linear dimension that is greater than the final thickness of the sheets, thereby resulting in an aesthetically pleasing “chunky” appearance. The apparatus used to slice the sheets produces a relatively smooth, uniform surface, and is capable of dramatically limiting the amount of variation in thickness within a finished sheet.Type: GrantFiled: April 23, 1998Date of Patent: March 6, 2001Assignee: Premark RWP Holdings, Inc.Inventors: Frank Bell Cloud, Robert Edward Respess

Patent number: 6167624Abstract: A method for producing a polymeric foamed material panel including the steps of providing a polymeric foamed material; and cutting (e.g. hot wire cutting) the polymeric foamed material until reaching a preconfiguration cut point. The method further includes cutting subsequently from the preconfiguration cut point a brace-receiving configuration in the polymeric foamed material; and sliding a brace member into the brace-receiving configuration to produce a polymeric foamed material panel. A method for forming a structure comprising engaging together a pair of polymeric foamed material panels produced in accordance with the method for producing a polymeric foamed material panel. A polymeric foamed material panel comprising a panel consisting of a polymeric foamed material, and a brace-receiving-configured slot disposed in the polymeric foamed material of the panel. A brace member is disposed in the brace-receiving-configured slot in the polymeric foamed material of the panel.Type: GrantFiled: November 3, 1999Date of Patent: January 2, 2001Assignee: QB Technologies, L.C.Inventors: Kenneth P. Lanahan, Thomas G. Durham, Stephen C. Foreman

Patent number: 6119567Abstract: A method and preferred apparatus (10) to cut a preform material which is biodegradable and preferably dispersible in water, to produce a shaped article, is described. The cut is produced without producing harmful fumes or leaving a harmful residue and preferably without charring at the cut. Preferably, only small amounts of carbon dioxide and water are produced at the cut. Shaped articles which are in sheet or block form or which are for 2-D or 3-D shaped article formation can be produced.Type: GrantFiled: July 10, 1997Date of Patent: September 19, 2000Assignee: KTM Industries, Inc.Inventors: Melvin S. Schindler, John F. Holland, Marcos Dantus

Patent number: 6098511Abstract: A method for cutting to length a strip-shaped profiled member of unvulcanized rubber material by a cutting edge includes the step of providing a speed between the cutting edge and the profiled member to be cut of at least 2.5 m/s during the cutting action. The device for carrying out the method includes a carriage and a tool with a cutting edge fastened to the carriage. The carriage has an acceleration path, defined between a rest position of the carriage and a side of the profiled member facing the carriage, of between 0.2 and 1 m. The carriage has a deceleration path, defined between an oppositely arranged side of the profiled member and an end position of the carriage, of at least 0.1 m.Type: GrantFiled: December 22, 1997Date of Patent: August 8, 2000Assignee: Continental AktiengesellschaftInventors: Fritz Rothemeyer, Horst Sergel, Harald Kranz, Michael Glinz, Gunter Homt

Patent number: 6089750Abstract: A material to be cut has a face to be cut with a cutting tool, and a cutout which temporarily brings the cutting tool into a noncontact state. Images of the cutting tool during the period when it attains an exposed state by passing over the cutout are captured with a camera mechanism at an interval of a predetermined delay time .tau.. A plurality of image information items obtained by these capturing operations include temperature change information of each location as the cutting tool gradually passes from the point of instant when it enters the cutout. Therefore, the image information items are arranged in relation to the exposure time from the point of instant, and a two-dimensional temperature distribution of the cutting tool at the point of instance is computed according to the tendency of change in image information.Type: GrantFiled: September 24, 1998Date of Patent: July 18, 2000Assignee: Sumitomo Electric Industries, Ltd.Inventors: Daisuke Murakami, Hideki Moriguchi, Akihiko Ikegaya

Patent number: 6050163Abstract: A saw arrangement includes the combination of a circular saw blade and a lubricating guide support assembly. The circular saw blade includes a saw plate having openings formed therein and carbide insert teeth disposed circumferentially about the saw plate. The lubricating guide support assembly includes two guide supports each having a bearing surface disposed immediately adjacent opposite sides of the saw plate at a spacing to the cutting area for proper alignment of the saw blade during cutting. At least one of the guide supports includes a recessed area containing liquid exposed to the saw plate whereat a thin film of the liquid is applied to the saw plate as it passes by the recessed area during cutting. The openings are arranged on the saw plate to pass by the recessed area and are dimensioned to receive liquid therein for transport away from the recessed area.Type: GrantFiled: January 15, 1999Date of Patent: April 18, 2000Assignee: Cutting Edge Designs, L.L.C.Inventors: Robert Wayne Gravely, Michael Monroe Lee

Patent number: 6007468Abstract: An apparatus is described for forming a web (N) that is permeable to liquids and designed to separate two environments and to allow the liquid to flow in one direction from one of said environments to the other, in which said web is caused to pass between two contra-rotating cylinders (5, 7) that are pressed against each other, one of said cylinders (7) having a surface provided with projections which cause perforations in said web (N). The cylinder (7) with the projections is turned at a peripheral speed greater than the peripheral speed of the other cylinder (5), with a consequent relative slipping action between the surfaces of the two cylinders (5, 7).Type: GrantFiled: April 15, 1998Date of Patent: December 28, 1999Assignee: Pantex S.r.l.Inventor: Claudio Giacometti
