Abstract: The invention relates to a machine tool monitoring device with an identification unity for identifying the operating situation of a machine tool. According to the invention, the machine tool monitoring device has at least one projection unit for defining at least one region to be monitored.

Abstract: The invention relates to a machine tool monitoring device having a detection unit for detecting an application in a machine tool. According to the invention, at least one component of the machine tool is used as a reflector for a transmitting and/or receiving signal of the detection unit.

Abstract: A machine for cutting slices from a cylinder of material. The machine has a machine frame with a holding assembly thereon for holding a cylinder of material for cutting and rotating the material cylinder about a central longitudinal axis. A disc shaped rotatable cutting blade is carried by the carriage assembly and drive means rotates the cutting blade. A carriage assembly is mounted on the frame for movement to present the rotating cutting blade to the rotating material cylinder for cutting the cylinder transversely into material slices. A brake mechanism is actuable to positively brake gripping chuck rotation upon cessation of the gripping chuck drive means operation. Moreover, a separate brake mechanism is operable to positively brake cutting blade rotation upon cessation of the cutting blade drive means operation. This braking prevents free running of the gripping chuck, material cylinder and cutting blade.

Abstract: A device is provided which permits the simultaneous cutting or bisecting of a plurality of tires. Large, vertically mounted, circumferentially slotted wheels each adapted to receive a circular cutting blade in each slot, receive the tires. The cutting blades are mounted overhead on a shaft which traverses a pivotally mounted beam which is raised and lowered by a piston. A brake is provided for engaging the tread of the tire, and tensioning means engages the lower rim of the tire to exert a downward pressure when the overhead beam is lowered. Turning power is provided to the cutting blades by means of belts or chains which connect a motive source with the shaft on which the blades are mounted. Collars on either side of the cutting blades engage the tire tread when the blades are lowered to turn the tire. A plurality of slots and corresponding cutting blades can be provided for each wheel with spacers to determine the width of sections cut from the tire.

Abstract: A sharpening device for the rotatable cutting rasp of a tire buffing machine comprises a cylindrical rotatable sharpening stone carried at the free end of an arm which is pivoted to the frame of the machine to allow the operator to bring the stone into contact with the rotating rasps. Engagement of the edge of the rasp with the periphery of the stone causes the stone to rotate at lower speed than the rasp due to an adjustable spring-biased brake acting on the stone. An adjustable stop arrangement prevents over-sharpening.

Abstract: A tire truing machine having a carrier for supporting and moving a motor-driven cutter to and from a mounted and driven wheel having a tire with means to vary the travel of the cutter according to the desired contour of the tire, including a new and improved cutter head having means for mounting the cutter blade onto the motor drive shaft so that the distance between the cutter blade and the housing may be closely controlled to prevent dirt and rubber from entering the motor housing and further having a new and improved means for both automatic and manual sharpening of the cutter blade, and more importantly, for preventing rubber from being drawn between the carbides and the blade to prevent binding of the machine.

Abstract: A tire truing machine that has a continuously orbiting band saw moving across a tool guide that has a plurality of adjustable guide members that can be shaped to the profile of the tire to be trued or contoured to a preexisting cam profile with the cumulative guide members defining an arcuately shaped recess or guide which positions the cutting edge of a band saw adjacent to the tread of a pneumatic tire in a precise profile control. The tire is chucked and rotated as the band saw operates on the tread surface or portions thereof to the profile set or adjusted.
