  • Patent number: 6837134
    Abstract: A string saw includes a housing, and an air box. The housing includes a first casing and a second casing combined with each other. The air box is mounted in the housing and has an inside formed with a receiving chamber communicating with the storage space of the first casing, so that the cut chips during the sawing process can be introduced from the storage space of the first casing into the receiving chamber of the air box. Thus, the string saw can provide the dust collection and chip drainage function.

  • Patent number: 6823763
    Abstract: A fabric cutting system for cutting a pre-selected pattern from a fabric stock and transferring the cut fabric piece to a workstation. The system includes a cutter assembly for cutting the preselected pattern from the fabric stock. A configurable pickup assembly is located between the cutter assembly and the workstation and adapted to pick-up and transfer the cut fabric piece to the workstation. A hold down table adjacent to the cutter assembly maintains the position of the fabric stock in a determinable relationship to the position of the cutter assembly and the configurable pickup assembly. In the preferred embodiment, the hold down table is vacuum operated and includes a moving mesh belt on which and the fabric stock is moved downstream towards the pickup assembly as the fabric piece is being cut by the cutter assembly. This arrangement results in substantially higher throughput through the fabric cutting system.

  • Patent number: 6648742
    Abstract: A dust director portable vacuum guard for mounting onto a bore of a portable angle grinder. The dust director includes a housing with parallel inner and outer walls and an end web adjacent to a straight barrel that is secured along aligned edges of the walls. The barrel is slotted from a forward dust collected end to the web and is stepped at a selected distance apart from the inner wall upper edge, functioning as a baffle. An attachment ring is pivotally mounted in the housing inner wall to releasably couple to an angle grinder bore and pivot around that bore upon release of a spring loaded thumb screw. An extension cover is included on an end of the housing to allow for sawing through a corner.

  • Patent number: 6615698
    Abstract: A dual-end cutting machine for trimming assembled blinds has fixed spacing between a pair of trimming units, which are adapted from conventional power miter saws. The blind assembly is clamped to a carriage that is movable on tracks between the trimming units, and adjustable stops are supported at opposite ends of the machine. The adjustable stops also have actuators for movement between an advanced position for positioning the blinds for cutting, and a retracted position that facilitates evacuation of scraps and chips from respective collector boxes wherein cutting takes place to a vacuum holding tank. A method for trimming includes clamping the blinds to the carriage with components aligned against one stop member, trimming that end of the blinds, moving the carriage to abut the blinds against the other stop, and trimming the other end of the blinds.

  • Publication number: 20030164076
    Abstract: During an unsupported roll change, a flap of paper resulting at the joining point can lead to disruptions in a processing station situated down-stream. According to the invention, the paper web (1) is advanced on a carrying element that is moved faster than the paper web (1), for example, on a suction roll (5). Said carrying element is arranged so close to the continuous paper web (1) that it catches the flap (8) of paper, which is located on the paper web (1), with frictional engagement. The flap (8) of paper is advanced with its rear side on the paper web (1) in a sliding manner and in relation to said paper web (1) in order to cause the leading part of the flap (8) of paper to arch in a wavelike manner. The arched flap (8) of paper strikes a blade (6) and is cut away until it can no longer cause any disruptions.

    Abstract: A depaneling system is disclosed for cutting a panel. The depaneling system comprises a tooling apparatus and a cutting apparatus. The tooling apparatus helps hold the panel in place with suction during cutting of said panel and collects dust particles generated by the cutting of the panel. The cutting apparatus is comprised of a housing, a drive motor, a cutting unit, and a drive connector. The housing separates the drive motor from the cutting unit. The housing comprises a first section and a second section separated by a dividing member. The drive connector, such as a belt, passes through the first section of the housing. The second section of the housing forms a path for the dust particles.

  • Patent number: 6595097
    Abstract: A band saw shielding device is linked with an elevation guiding set of a band sawing machine comprising a wheel on which the band saw runs, and a stop portion. The shielding device comprises a main housing fastened with the elevation guiding set and having a front plate with a hollowed portion, a position confining portion disposed longitudinally and a band replacing slot, a receiving space formed in the center thereof for receiving the band saw; a movable cover having a slide plate disposed slidably at the position confining portion of the main housing, a stop edge connected with the slide plate and stopped by the stop portion of the band sawing machine. The shielding device cooperates with the elevation guiding set to surround the band saw, so as to prevent the band saw from being a safety hazard. The wheel is still received in the hollowed portion without interference when the main housing is raised.

  • Patent number: 6578460
    Abstract: A blade guard and lifter therefor surround the saw blade, interlocking when raised by a workpiece as a result of relative movement caused by a secondary linkage. Two pair of primary linkages pivotally connect the blade guard to the splitter. The dual secondary linkage pivotally attaches the parallel plates of the lifter to one of the two pivot points of the primary linkages. Any lifting force is resisted by the rigidity of the primary link that does not share a pivot point with the secondary linkage. A dust collector can be provided to the table saw to minimize respiratory hazards.
