A cutting apparatus including a holding unit for holding a workpiece, a cutting blade having a peripheral cutting edge for cutting a workpiece, a spindle unit including a spindle for rotating the cutting blade, a blade cover mounted on the spindle unit for covering the cutting blade, the blade cover having a bottom portion formed with a slit for allowing projection of a part of the cutting edge of the cutting blade, and a cutting fluid supplying unit for supplying a cutting fluid to the upper surface of the workpiece on both sides of the slit. The cutting fluid is not directly supplied to the cutting blade, but it is supplied to the upper surface of the workpiece. Accordingly, there is no possibility that the cutting fluid may be scattered by the rotation of the cutting blade.

A machine control and data logging station, intended for use with a saw or other machine tool, features a processor which monitors a number of input lines, a real time clock and time stamp function. Any change of input signals from the machine tool will be recorded in flash memory. Both wired and wireless outputs may read the memory at any given time. Optionally, hardware or software data communication encryption may be employed to provide increased confidentiality and security. The station continually monitors sensor inputs and can react automatically to emergency-stop the machine tool upon sensing a dangerous condition.

A device for cutting paper webs comprises a substantially continuously operated region of a papers supply, a discontinuously operated region of transverse severing of a separating the paper web, and a buffer region (15) for coupling the continuously and discontinuously operated regions. At least one receptacle (17) open at the top is provided in the buffer region, into which the paper web(s) (3, 3) are guided so as to be looped in a freely suspended manner. The buffer region is arranged after a longitudinal cutting device (9) for producing at least two longitudinal webs (3, 3), whereby at least two webs extending separately and adjacently to one another are guided in the receptacle or at least two receptacles are arranged adjacently to one another or adjacently to one another at an offset, wherein the paper webs are guided into the receptacles.

A web cutting system is provided for use with a single transfer insert placement mechanism having at least one puck for transferring a discrete web and a continuous web feeding mechanism for feeding a continuous web wherein first and second rollers having substantially parallel axes and being aligned with one another form a nip at their juncture, an anvil is attached to one roller, a die is attached to the other roller, a vacuum source is coupled to one of the rollers, a plurality of vacuum apertures is formed in the same roller. One of the rollers is positioned adjacent to the single transfer insert placement mechanism and to the continuous web feeding mechanism. The continuous web is applied to one roller and at least one discrete web is transferred from the puck to the same roller after which a die cutting process of the webs occurs at the nip.

An apparatus and method is provided for single transfer insert placement. The apparatus receives continuous web material and cuts a discrete section or pad from the web. The pad is then supported on a single transfer surface. The single transfer surface then may spin the supported pad to a desired angle and provide the pad to a receiving surface at a desired interval. The web material can be cut to different insert lengths and the placement location varied.

A paper discharging apparatus comprises: a first conveying unit; a second conveying unit which includes a pinch roller and a feeding roller that are arranged closer to the downstream side; a movable mechanism which moves a surface part between a first position that the surface part is not contacted with the pinch roller and a second position that the surface part is contacted with the pinch roller through the paper so as to push the pinch roller; a control unit which moves the surface part to the second position, clamps the paper by the pinch roller and the surface part, and conveys the paper, thereby bending the paper, and which moves the surface part to the first position and clamps the paper by the pinch roller and the feeding roller, and rotates the feeding roller, thereby discharging the paper from the conveyance path.

A web cutting system is provided for use with a single transfer insert placement mechanism having at least one puck for transferring a discrete web and a continuous web feeding mechanism for feeding a continuous web wherein first and second rollers having substantially parallel axes and being aligned with one another form a nip at their juncture, an anvil is attached to one roller, a die is attached to the other roller, a vacuum source is coupled to one of the rollers, a plurality of vacuum apertures is formed in the same roller. One of the rollers is positioned adjacent to the single transfer insert placement mechanism and to the continuous web feeding mechanism. The continuous web is applied to one roller and at least one discrete web is transferred from the puck to the same roller after which a die cutting process of the webs occurs at the nip.

A cutting machine can include a cutting machine body that is movably supported above a table and capable of vertical movement, the cutting machine body can be positioned at an upward waiting position and a lower end position. The cutting machine body can include an auxiliary cover positioned around a portion of a blade and including a projection. When in the upward waiting position the auxiliary cover is not able to move upward because of the position of the projection, and in the lower end position the auxiliary cover is able to move upward.

A vacuum table (18) includes an introduction section (102) in fluid communication with a vacuum chamber (120) and a compartment (139) dividable by an adjustment partition (156) into primary and secondary vacuum chambers (139a, 139b). Adjustment plates (130) having adjustment apertures (138) are positionable over apertures (128) of the conveying surface (100) of the vacuum table (18) generally perpendicular to the conveying direction. Film (20) extends from between the nip of pinch rollers (12, 13) to the conveying surface (100) and is tensioned therebetween to be cut in excess of 105 cuts per minute by a servo motor controlled rotary cutter (30) which stops after each cut. The shaft (32) of the rotary cutter (30) includes a bore (310) extending from the idle end to provide servo-control loop stability.

A cutting and dust or slurry collecting assembly that comprises: a) a circular saw blade (4) b) a blade guard (5) c) a cover device (6), and the cover device (6) has a front end (31), a rear end (32), a top surface (34), a bottom surface (36), elongated sidewalls (35), and a longitudinal passage (45,46) for the saw blade, d) the blade guard (5) and the cover device (6) being pivotally connected or connectable to one another via a hinge (40) in or adjacent to a lower rear corner of the blade guard (5), such that the cover device and the blade guard can be turned in relation to each other, e) a discharge member (52) is provided at the rear of said hinge and has an outlet (58) which can be connected to a vacuum source, f) a connection member (12) connects the discharge member (52) with at least one of the longitudinal passage (45, 46) and the cut created rear of the longitudinal passage, g) that the direction of rotation of the saw blade (4) is such that a circumferential part of the blade which has passed beyond the bottom surface of the cover device will move in a direction upwards-rearward towards the bottom surface In particular a rear arm distance (LR) between the hinge (40) and the rear end (32) is bigger than 0.2R and preferably bigger than 0.25R, thereby enabling a turning of the cover device (6) by pressing the rear end (32) towards the structure to be cut.
