Abstract: A hand-held band saw has a handle for grasping the band saw, a motor, a drive wheel driven by the motor, a driven wheel and a continuous blade disposed about the drive wheel and the driven wheel. A portion of the continuous blade is positioned in a cut zone to perform a cutting operation. A workpiece guard is spaced from the continuous blade and positioned generally between the cut zone and the handle for limiting movement of the workpiece after the cutting operation.

Abstract: A cutting segment for a False Drum (100,200,300) having a cylindrical outer surface (202,306) comprises a slot (204,224,330) extending generally axially from end-to-end of the cylindrical surface, a door panel (322) having substantially the same size and shape as the slot; and a mechanism (320) for opening and closing the door panel. The mechanism for selectively opening and closing the door panel includes an elongate lever (324), one end of which supports the door panel, the other end of which is pivotally attached to a stationary portion (point) of the drum, a spring (326) extending between an inner surface of the door panel and another stationary portion of the drum; and an inflatable pneumatic tube (328) disposed between the lever and yet another stationary portion of the drum. There is thereby provided a method of supporting material overlying the cutting slot of the False Drum, by opening the slot when cutting the material, and closing the slot when not cutting the material.

Abstract: A dry end tail cutter for a papermaking machine comprises a slotted housing for accommodating the traverse of a cutter in a cross machine direction relative to the machine. A drive motor mounted on the housing drives a slot closing band around a pair of opposed pulley wheels. The slot closing bank is entrained around the pulley wheels and has its opposite free ends interengaged with a motor mount disposed within and slidable relative to the housing. A knife motor is carried by the motor mount and moves therewith. A rotary knife is driven by the knife motor. The band functions to close the slot forwardly and rearwardly of the knife as the motor mount and knife are traversed in the cross machine direction relative to the papermaking machine.

Abstract: The invention relates to a device for closing up the grooves in the tops of the front and rear tables of a machine for sawing materials in sheets, these grooves being perpendicular to the sawing-line. This closing device is characterized by the fact that it comprises, for each groove (9), an obturator (13) activated by means of propulsion (20, 21, 34) and subjected to a vertical course to fit into the groove (9) of the table (5, 6).

Abstract: A saw guard, especially for preventing splinters and the like for being thrown out from a saw, in which a flexible, strong, wear resistant material, such as belting, is cut into strips and the strips are connected to a housing which covers the saw from above so that a row of strips in side by side relation are in front of the saw while a row of strips arranged in parallel spaced aligned relation extend along at least one side of the saw. The strips along the side of the saw and being spaced apart permit free circulation of air through the sawing region to remove sawdust and the like therefrom but are effective in stopping splinters and the like from being thrown off from the saw because the arrangement of the strips are in parallel spaced relation.

Abstract: A cut-off machine includes a housing having a top surface with an elongated slot therethrough. A rotatable cutting disc is mounted within the housing for raising and lowering movement through the slot to cut workpieces supported on the top surface. Elevating means is selectively operable for moving the cutting disc in raising and lowering directions. Clamp means on the top surface clamps workpieces thereagainst for cutting by the disc. A cover moves between open and closed positions for selectively covering the clamp means and the top surface in outwardly-spaced relationship thereto. Slot blocking means beneath the top surface moves between blocking and unblocking positions for selectively blocking movement of the disc upwardly through the slot. Selective operation of control means for the elevating means is also dependent upon safety control means operated by all of the cover, clamp means and slot blocking means.
