    Abstract: A workpiece being processed on a machine tool is moved by control devices to the tool head or work station of the machine mechanically or automatically. A stop defines an area around the work station from which the holding devices must be kept to prevent damage. As soon as a holding device reaches the limit of the danger zone around the tool head, it is switched into a setting releasing the workpiece and moves into a position away from the work station. The machine has a switching element connected to each holding device to be so movable, and the switching element has a switching slide which is acted on by an applied force and is supported in a first position until it abuts the stop when one slide position connects the energy source to the drive of the holding device to move it away from the stop. In another slide position, the connection to the energy source is broken and the holding device returns to the workpiece holding position.

The stabilizing apparatus includes an elongated base for attachment to the tool, an elongated adjustable support that is essentially parallel to the base, and an interconnecting structure that enables the adjustable support to move relative to the base. When a workpiece moves toward the tool, it displaces the adjustable support toward the base thereby compressing springs in the interconnecting structure. This produces a clamping force against an opposed work support surface that stabilizes the position of the workpiece transversely to the direction of travel but allows movement along the work path. Multiple stabilizing apparatus can be used to provide both vertical and horizontal clamping forces.

  • Patent number: 5125306
    Abstract: An overload assembly is disclosed for use with a tube cutting apparatus of the type having a die set for holding a tube while a blade cuts the tube. The die set comprises two die jaws having cam followers which contact a die jaw cam to move the die jaws to clamp the tube. The overload assembly allows one of the die jaws of the die set to stop moving when an obstruction is encountered. The overload assembly includes a spring mounted through a lever arm to the cam follower. An overload biasing force is applied to the cam follower through the lever arm. If an obstruction force exceeds the overload biasing force, the lever arm is rotated and the effective length of the lever arm is reduced, causing the overload biasing force to decay to a lesser value. A scarfing blade may initially score the tube prior to cutting. In one embodiment, the overload biasing force is applied to the die jaw which does not encounter a binding force between the scarfing blade and the tube.

  • Patent number: 4262386
    Abstract: Apparatus for holding the head of an animal severed from its body for use in cutting the edible portions from the bones. The head is clamped between first and second members rotatably about a common axis and displaceable towards each other. The snout is received in the appropriately configured first member and a prong of the second member penetrates into the foramen magnum in the occipital bone. The rotation of the first and second members may be braked or arrested by a friction brake. To move the lower jaw away from the upper jaw in order to remove the lower jaw a hook member engaged the lower jaw and pulls it open by means of a foot-operated piston-and-cylinder unit. Another piston-and-cylinder unit forcibly drives the first and second members toward each other to firmly clamp the head therebetween.

  • Patent number: 4201032
    Abstract: An apparatus for cutting textile strands and forming the cut strands into bundles including a means for supplying the textile strands. A means for positioning the textile strands funnels the textile strands into a grouping of substantially parallel strands having a substantially cylindrical cross-section. A means for wrapping the parallelly arranged strands places a wrapper of paper around the strands and secures it by adhesive. A capstan guides the parallel strands to an accumulator pipe which has at its end a means for cutting the strands. The strands are held and retained so that a blade can cut them and the ends of the strands of the bundle are joined by adhesive or heat. An adhesive strip is tangentially attached to the sides of the bundles so that they may be wrapped around a rotating shaft.

  • Patent number: 4036090
    Abstract: A carriage assembly for automatic face up one way spreading of multiple plys of fabric or any other web-like material of a predetermined length, which is automated to operate in a continuous manner in the absence of operator manipulation at the termination of each fabric spreading cycle. The device incorporates a fabric or web-cutting assembly normally enclosing a transversely traveling severing blade and means for automatically engaging the free end of the fabric after sequenced severing so as to maintain the fabric in a fixed relation relative to the assembly during return or non-spreading carriage motion thereby preventing disturbance or change of position of the free end of the fabric as caused by carriage motion airflow, so that upon automatic recommencement of spreading, the end of the fabric will be deposited at a predetermined position on the spreading surface which will be accurately repeated for each subsequent automatically deposited ply of fabric, thereby providing maximum fabric utilization.

  • Patent number: 4031788
    Abstract: A chop saw for selectively cutting logs to various lengths includes a motor-driven circular saw blade mounted at the outer end of a saw carriage pivoted to a fixed base. A rotary crank mechanism driven by a hydraulic motor on the carriage oscillates the carriage about its pivot to feed the saw blade into and out of a log held in cutting position alongside the carriage by hydraulic cylinder-operated clamp arms which are also mounted on the fixed base. A crankshaft of the rotary crank mechanism carries a cam which operates a hydraulic flow control valve in the hydraulic circuit of the carriage drive motor to reduce the speed of the motor and thus carriage travel only when the saw blade cuts through the log. Limit switches in an electrical control circuit and operated by cams on the crankshaft control the operation of valves in hydraulic circuits for the clamp cylinders and carriage drive motor to coordinate the positions of the carriage with the closing and opening of the clamp arms.
