  • Patent number: 8161855
    Abstract: A cutting machine secures safety of a worker during movement of a head without lowering production efficiency. When moving a cutting head without cutting material to be cut upon a table, a moving truck and the cutting head are moved at a higher speed as compared with when cutting the material to be cut. If, when the moving truck and the cutting head are moving at high speed, a worker who is present upon the table intercepts either of light beams which are located in front of and behind a horizontal beam, then this movement speed is decelerated to a safe low speed, but the task of cutting the material is not interrupted. Subsequently, when the worker approaches the horizontal beam closer, and contacts a wire or a bar in the vicinity of the horizontal beam, movement of the moving truck and the cutting head is forcibly stopped.

  • Patent number: 7124671
    Abstract: In a web cutter where a blade is used to cut a continuous paper web into sheets, a tractor is used to move the web past the blade for cutting. The tractor operates in a start-and-stop cycle so that the web is temporarily stopped to allow the blade to lower and shear the web. The tractor accelerates in the next cycle to move another length of paper downstream from the blade. A high-speed cutter requires high acceleration of the tractor. This acceleration force causes the web to whip up uncontrollably, causing the web to break or wrinkle. To reduce the web breakage, a moving mechanism positioned upstream from the tractor and operate a second motion cycle is used to move the web toward the tractor such that a loop of paper is formed upstream of the tractor, thereby reducing the whipping action of the web.

The webs have distinct portions such as tabs. The locations of the distinct portions of the moving webs are sensed by sensors. End cuts are simultaneously cut through the multiple stacked webs with the cutter to produce separate roofing shingles from the webs. The movements of the webs are controlled, based on the sensed locations of the distinct portions, so that the end cuts of the roofing shingles are positioned at predetermined locations relative to the distinct portions.

  • Patent number: 6330848
    Abstract: In the operation of cutting a metallic work material, if the rotation of an electric motor 21 is reduced by a reduction gear mechanism including a gear mechanism and transmitted to a main shaft 23 and the metallic work material is cut by a circular saw 28 attached to one end of the main shaft, the moment of inertia I (kgf·m·sec2) of the main shaft is set to be more than F×(D/2)/[1000×250×(N/60)2] while an outside diameter of said circular saw is D (mm), the number of revolution is N (rpm) and a cutting force per tooth as a component of force in tangential direction is F (kgf). By so setting, at the initial cut positions of the work material and in a region in which the number of cutting related teeth Zi is 1.0 or less at the final cut positions, the moment of inertia is high compared with a cutting torque applied to the main shaft by intermittent cutting resistance, so that the rotational variation of the main shaft is very small.

  • Patent number: 6269720
    Abstract: Laminated elements, which may be constituted, for example, by labels to be applied to articles while in movement, are formed from a strip provided by a feeding device. The strip moves forward onto a reception unit, passing through a cutting zone. The individual laminated elements are formed by causing the cutting unit to come into action when the length of the strip paid out by the feeding unit is equal to the desired length of the labels. The cutting unit preferably includes a revolving knife and a counterknife, where the latter consists of a non-driven roller supported in a cradle that is lubricated and exerts an elastic force against the cutting unit. Preferably, the reception unit realizes the step of applying the individual laminated elements to their respective articles.
