    Abstract: A cutting saw machine has a motor arranged to be installed in a table frame which is used for supporting the cutting table and the coolant tray instead of mounted on the cutting head, so that the cutting head thereof can be made of light material to reduce the overall weight of the machine. Moreover, the motor is positioned below the coolant tray that can prevent direct contact with the user, and that the coolant tray also provides a cool surrounding to the motor that can help the motor to reduce its heat when it is functioning.

  • Patent number: 6230598
    Abstract: The present invention pertains to an automatic cutting device which can be utilized for cutting woody plant material (e.g., stem, stalk). The subject device can comprise a housing having a fixed blade attached thereto. A movable blade, pivotally connected to the fixed blade, can be attached to an activating device for movement. The activating device is preferably a pushrod activated by an electrical solenoid which produces the force necessary to push the movable blade against the fixed blade in a cutting action. A spring can be used to return the movable blade to the open position between cuts. The solenoid can be activated by a switching means which is triggered by a lever device located in close proximity to the cutting portion of the blades. In a specific embodiment, as the stem is lowered, the lever is depressed which triggers the switch to activate the solenoid. The solenoid forces the push rod to push the movable blade against the fixed blade in a single cutting action to cut the stem.

    Abstract: A punch is disclosed, which can be used with an automatic paper feeder or a plane paper copier for receiving sheet-like members one by one from such machine and forming punched holes in each sheet-like member at a punching position thereof. A punching member is disposed in correspondence to the punching position for effecting punching with a predetermined stroke. A dimensional strain generated in an electrical-to-mechanical conversion element such as a piezoelectric element or a magnetostriction element is transmitted after enlargement by an enlarging member disposed to surround the element through a movable output terminal and an operation transmission lever to the punching member to cause high speed operation thereof in a predetermined stroke range. High quality punched holes free from curved edges or the like difficiency thus can be formed even in a continuous feed state without holding the sheet-like members stationary for a while.

  • Patent number: 5095792
    Abstract: A table top machine of box-like construction has a cutting mechanism in its interior and an entry bore that receives a microhematocrit tube. In a first embodiment, the end of a tube inserted into the machine closes a switch that activates the cutting mechanism so that tubes are always cut in the same place, without regard to the ratio of linear space in the tube occupied by red blood cells, clotted blood cells and clear plasma or serum. In a second embodiment, a photoelectric cell positioned at the inner end of the entry bore triggers the cutting mechanism when the end of the tube filled with red or clotted blood cells has passed the eye. Thus, tubes are cut at differing positions along the extent of the tube, depending upon how much each tube is filled with red blood cells or clotted blood cells and how much is filled with clear plasma or serum.

The apparatus moves to a position aligned with holes in a stack of sheets. The second strip is deposited on top of the stack with the holes thereof aligned with the holes in the sheets. The first strip is then raised so that the studs pass through the holes in the sheets and the second strip and pressure is applied forcing the strips toward each other. Blocks then move transversely, bending down the portions of the studs projecting beyond the second strip and snapping these portions into the grooves. The steps are performed sequentially using a single pneumatic cylinder for all but the first-mentioned step.

A web supply unit includes a web take-up unit to maintain a constant tension in the continuously moving web to the bag making machine. The web notches are phased with the bag making machine to locate the notches centrally of each bag. During starting and stopping, the web take-up unit changes the web length moving through the notching unit at normal full web speed operation and the web length variations are minimal. A programmable notch controller actuates a stepper motor to rotate the notcher. The controller responds to a control signal to form a notch. A programmable switch is coupled to the bag making machine to generate a first control signal for each bag cycle and is phased with the full web speed to locate the notch centrally of the bag.

Next, the tongue is returned to a vertical position and the staple is pressed upwardly into a relieved portion of a rotary knife. The knife then slices off the top of the staple and removes the sliced off portion. Remaining portions of the staple are stripped from the paper as it is withdrawn from the apparatus.

A first feed roller is rotated via a clutch upon energization of a solenoid for the clutch when the leading edge of the original is sensed by the switch to connect the solenoid to a D.C. power supply via a capacitor. When the capacitor is nearly charged, current flow to the solenoid has diminished to a level where the armature of the solenoid is returned to its unactuated position. The leading edge of the copy paper is moved from a solenoid operated cutter to a second feed roller by the rotation provided by the first feed roll in response to the energization of the solenoid for the clutch.
