Publication number: 20030046787Abstract: A web cleaner (20) for removing debris that clings to the surface of a substrate during a printing process. The cleaner (20) uses a number of idlers (26) which hold a web (22) taut therebetween, with the web driven at high speeds by a printing press (24). The cleaner (20) utilizes a pair of counter rotating, textured rollers (28) that are positioned between the idlers, with one roller positioned on each side of the web in close proximity therewith and each roller rotates in an opposite direction to that of the webs flowpath. A skiving bar (36) is positioned at an angle between 90 degrees to 180 degrees to the web bordering each roller in adjacent relationship for directing the air into a plenum (44) that covers each roller and skiving bar. The plenum (44) is used to collect the debris detached from the web surface by air currents formed by rotation of the rollers creating an air film on the web surface. The same air currents also produce a positive air pressure within the plenum.Type: ApplicationFiled: September 4, 2001Publication date: March 13, 2003Inventor: Paul C. Howard

Patent number: 6487750Abstract: A device is provided for cleaning of elongate flexible hoses. The device has a smooth radiused low friction entry fairlead that allows the soiled hose to be readily pulled along a straight line path through the cleaner. After entry, the surface of the hose passes through a set of pliant wiping flaps that closely engage the full circumference of the hose, wiping dirt and debris from its surface as it enters the active cleaning region. In the cleaning region, multi-stream jets of high pressure water blast and scour the moving hose's surface, and the hose exits through a second set of pliant wiping flaps that wipe any adherent water from the hose surface. The active cleaning region, filled with water spray, is maintained at a negative pressure by means of an associated suction system which also sucks out the dirty water and debris. The pliant wiping flaps act as partial pneumatic seals, allowing maintenance of the negative pressure in the cleaning region.Type: GrantFiled: July 21, 2000Date of Patent: December 3, 2002Inventor: Terry A.

Patent number: 5697116Abstract: The invention generally relates to a device for cleaning and accelerating objects which are globular. In particular the invention relates to a device for cleaning golf balls with a high throughput of balls. Devices of this kind are mainly used on golf courses for practice operations as for that purpose, on the one hand, a great number of golf balls is used and, on the other hand, the balls get dirty when they touch the soil or have contact with very short grass residues, which result from the cutting of the greens. Especially the dirt sticking between the dimples of the golf balls, which might dry and become hard, leads to an extremely negative influence on the flight properties of the golf balls. In order to guarantee smooth and economic practice operations, a device of this kind must ensure a high degree of cleaning power as well as a high throughput of balls.Type: GrantFiled: March 11, 1995Date of Patent: December 16, 1997Inventor: Georg Loferer

Patent number: 5613286Abstract: A wire cleaning apparatus in which three motor driven rotary wire brushes are mounted on a frame for rotation about axes generally radially of a wire pass line with the axes of the brushes being angularly and axially spaced apart relative to the pass line, and with the rotary brushes each having a bristle end face transverse to the axis of rotation and disposed adjacent the pass line so that the bristles of each brush move crosswise of the wire and in relatively opposite directions during each revolution of the brush. A wire guide shoe is associated with each of the wire brushes for guidably engaging and supporting the wire at a side of the pass line opposite the end face of the associated wire brush to control the position of the wire and the depth of penetrating the wire as it passes the end face of the associated brush.Type: GrantFiled: September 8, 1995Date of Patent: March 25, 1997Assignee: Fastener Engineers Group, Inc.Inventor: Troy A. McCabe

Patent number: 5491871Abstract: A solder paste or conductive ink printer stencil wiper apparatus combining a dual action of sucking stencil holes and simultaneously wiping the bottom of the stencil for excess solder. The apparatus includes a vacuum nozzle constructed and arranged to draw excess solder gathered in the holes of the stencil through the nozzle to a collection reservoir. The apparatus also includes a wiping element for wiping the bottom of the stencil at the same time the vacuum is sucking solder out of the stencil holes. The wiper includes a wiper fabric to wipe the bottom of the stencil. The fabric is provided on a roll, and the fabric is pulled through a series of rollers by a motor and collected on a take-up roller.Type: GrantFiled: December 8, 1993Date of Patent: February 20, 1996Assignee: Delco Electronics Corp.Inventors: Douglas M. Reber, Jennifer E. Clark, Timothy D. Garner

Patent number: 5477584Abstract: A device for cleaning lamellas has a housing and at least one pair of brush rollers rotatably supported within the housing, wherein a lamella is guided through the pair of brush rollers. A pair of conveying rollers is rotatably supported within the housing and the lamella is guided between the pair of conveying rollers for conveying the lamella through the device. A support plate extends in the direction of conveying between the brush rollers and the conveying rollers for supporting the lamella in the device. The support plate has first cutout for the brush rollers and a second cutout for the conveying rollers. The brush rollers are driven in a direction counter to the conveying direction.Type: GrantFiled: January 7, 1994Date of Patent: December 26, 1995Inventor: Egon Thumm

Patent number: 5421056Abstract: A cleaning apparatus for cleaning a semiconductor wafer comprises a spin chuck having a turn table. A gas supplying passage is formed in a shaft for supporting the turn table to supply a protecting gas to the rear surface of the wafer. A conical movable member, arranged to cover an end off the shaft, is movable upward and downward in accordance with the flow off the protecting gas supplied thereto. Inner ends of three reciprocating arms, supported by the turn table and extending in radial directions, abut against an outer surface of the movable member and biased by springs. Fixed pins are arranged on the turn table at positions which divide the circumference of the turn table into three equal parts, along the edge of the wafer. Three swingable levers are arranged such that one is provided between two adjacent fixed pins. One end of each swingable lever is connected to the outer end of each reciprocating arm and the other end of the lever has a pin brought into contact with the edge of the wafer.Type: GrantFiled: April 19, 1994Date of Patent: June 6, 1995Assignees: Tokyo Electron Limited, Tokyo Electron Kyushu LimitedInventors: Kiyohisa Tateyama, Michiaki Matsushita

Patent number: 5415671Abstract: A method for cleaning sod being transported on a perforate conveyor belt which includes at least one vibratory position and a powered brush position for removing the earth from the sod. This method and apparatus may be attached to a farm vehicle at the sod harvesting site or free-standing at a remote location. This present invention removes the earth in a substantially dry condition so that the earth may be returned directly to the harvest site or conveyed to another location, A subsequent water bath stage is disclosed for the removal of unwanted dust on the sod.Type: GrantFiled: May 23, 1994Date of Patent: May 16, 1995Inventors: Darrell H. Bouchard, Brian L. Bouchard

Patent number: 5405450Abstract: An automatic tack-off machine comprises a generally cylindrical rotary brush for lifting dust, dirt and sanding particles from the surface of a body to be painted without contacting the surface and a control system to position the brush is spaced noncontacting relation to the surfaces to be cleaned. The brush has strands of polymeric material that are radially extended and electrostatically charged by rotation with the control system operating to position the free ends of the strands in close proximity to the body. An ionizing system neutralizes the static charge in the strands to enable a vacuum system to remove the dirt particles from the brush.Type: GrantFiled: November 22, 1993Date of Patent: April 11, 1995Assignee: Hose Specialties/Capri, Inc.Inventor: Walter J.
