Abstract: A cutting mechanism for a roll fiber product comprises two clamping devices for clamping the roll fiber product, and a blade for cutting the roll fiber product. The two clamping devices are respectively connected to a push device. During the cutting process, the push devices drive the clamping devices and the roll fiber product thereon swinging so that the two clamping devices break the roll fiber products to reduce the contact area and the friction between the blade and the roll fiber products. In addition, two clamping devices are respectively connected with a push-pull device for increasing the size of the gap therebetween, so as to prevent the blade from touching the cut roll fiber products. Thus, the cutting mechanism of the present invention is able to reduce the wear rate of the blade, and improve the yield rate of the roll fiber products.

Abstract: A trimming apparatus comprises a conveying device, a movable upper knife, an immovable lower knife, a movable press crosshead, a first drive, and a control unit. The print product is pressed down with the press crosshead. The pressed down print product is trimmed with the upper and lower knives. The press crosshead is lifted following the step of trimming operation. Subsequent to lifting the press crosshead, the upper knife is lifted. The trimmed print product is conveyed with the conveying device.

Abstract: A miter box is comprised of two incomplex components, namely, a base and a U-shaped guide member, which are assembled by engagement of a pivot post on the guide member within a passage extending normal to the surface of the table of the base. An assembly for clamping the workpiece against a fence member on the base consists of a lug that is engageable at each of numerous locations along the length of a channel for location proximate the fence, and a clamping piece that is rotatably mounted on the lug piece for being turned into clamping engagement with the workpiece.

Abstract: An apparatus for supporting an elongated circular product during cutting includes a fixed lower support frame and a movable upper support frame. Right and left bottom support links include a lower end which is pivotally connected to the lower frame. Right and left side support links include a lower end which is slidably supported by a slot in the lower frame, an intermediate pivot point which is pivotally connected to the upper end of one of the bottom support links, and an upper end which is engageable with the product. The upper frame includes right and left guide surfaces which are engageable with the product. When the upper frame is moved downwardly toward the lower frame, the guide surfaces of the upper frame move the upper ends of the side support links closer to the center of the product.

Abstract: A quick clamping vice structure for a circular saw comprising a vice seat, a fixed seat, a screw rod, a seat member, a base and an electric saw, wherein, the vice seat is disposed in opposition to the fixed seat and is combined with the base, the vice seat is connected with the screw rod, while the screw rod is connected with the seat member, the electric saw is provided on the base, the vice structure is characterized by that: the seat member has a receiving chamber with an elastic member therein to abut against a screw guiding block, and an engaging groove is provided on the lateral wall of the screw guiding block to abut against a shifting rod; by such abutment and by an engaging portion provided on the bottom of the screw guiding block cooperatively arranged with the screw rod in a hole on the seat member, an effect of quick clamping and positioning as well as stable and firm clamping can be obtained.

Abstract: A device for preparing and opening a roll of a strip of supple material. A flat blade is provided and is inserted from one side of the roll to separate the top layer, which is to be cut, from the lower layers. When the top layer is cut, the cutting portion of the cutting blade comes to rest against the flat. A clamp holds the cut layer and a transferring device handle the cut top layer.

Abstract: The present invention relates to shearing apparatus, and method of operating the same. The apparatus may include a plurality of spring clamping members positioned longitudinally along a first die shoe, the clamping members positioned in raised stepped sequence from a centerline perpendicular to longitudinal sides of the die shoe to sequentially contact with the sheet material. The shearing apparatus may include a die assembly having linear bearings and guide rails for guiding movement of the die shoe, and gas springs which return the die shoe to the open position. The shearing apparatus provides straight cuts with a maximum cut-edge tolerance of 0.0015 inch. The shearing apparatus may include a second die shoe having an angled blade to allow a higher shear to break ratio.

Abstract: The clamping device has a stationary, substantially vertical clamping face (5) for the workpiece, arranged at right angles with respect to the feed direction of the saw band. A movable clamping jaw (8) is horizontally movable with respect thereto, the clamping jaw (8) having a substantially vertical clamping face (9). The movable clamping jaw (8) is formed as a clamping bridge (7), reaching over the machine table. The fixed clamping face (5) also reaches over the machine table, while leaving a passage for the saw band. The ends of the clamping bridge are guided horizontally beside the machine bench, for clampable adjustment perpendicular to the clamping faces (5, 9), the clamping bridge (7) being pivotable on guide blocks (22, 23) slidable on guide rails next to and below the table (2) of the saw, so that the clamping bridge can clamp a workpiece (3) between the clamping faces, by a toggle connection to a handle, or release the movable bridge.

Abstract: The present invention relates to a shearing machine in which the upper shearing blade can be easily adjusted and positioned. The upper blade is held on a pivotal plate member which is pivotally held on a ram by means of a hinge means to be rotated to adjust of the position of the upper blades. In addition, a hold down member is provided for holding a work-sheet. The hold down member is arranged to be urged by a toggle joint to hold the work-sheet at a reduced speed with an increased force after coming into contact with the work-sheet. A scrap removal member is also included in the shearing machine such that scraps can be easily removed without mingling them with the finished sheets. The scrap removal member removes scrap without idle time between feeding the work-sheets to be sheared. The shearing machine is so arranged that scraps are taken away directly to a scrap box as soon as the work-sheet has been completely sheared into its finished product.

Abstract: The pressure beam is adapted to be used in sawing machines for cutting workpieces such as panels or packs of panels (P), of the type comprising a workpiece support table (L) having a straight longitudinal slot defining a cutting line and a sawing tool (Z) movable along the cutting line. The pressure beam is arranged above the workpiece support table (L), extends along the whole length of the cutting line and consists of two pressure elemments (R, R') arranged at both sides of the cutting line, parallelly thereto. Each pressure element (R, R') can be raised and lowered independently of the other and laterally moved by slides to vary the distance of the pressure elements (R, R') with respect to the cutting line located between them.
