  • Patent number: 4586356
    Abstract: Process and apparatus for preventing defects in the symmetry of rolled H-beams or I-beams, i.e., a faulty position of their webs (4) in relation to their flanges (5), by correcting such defects in situ. The differential between the torques applied to the upper and lower rolls (1,2) of the rolling stand is determined and compared to a predetermined threshhold value (.delta.). Any excess of the measured value over the threshhold value is eliminated by correction of the elevation of the inlet table of the rolling stand so as to reduce the measured value to below the threshhold value.

  • Patent number: 4586855
    Abstract: A face milling tool is described including a holder securable to the end of a rotatable spindle. Cutting inserts are detachably secured to the end face of the holder at a radial distance from the axis of the spindle. The cutting edges of the inserts extend outwardly of the holder end face such that the cutting edges are free to engage and machine the surface of a workpiece. The inserts are of a wafer-like form and means are provided for detachably securing the inserts to the holder through a central axial aperture in the inserts. The securing means lies within the outer end face of each insert and the cutting edge of each is substantially straight, being formed by a portion of an edge at the intersection of the insert side wall and the end face. Each insert lies at such an angle to the plane of the workpiece that the insert side wall forms a rake face and the outer end face of the insert forms a clearance face and the straight cutting edge lies at a small radial shear angle.

  • Patent number: 4586357
    Abstract: A wire forming apparatus for making springs with coiled body portions and end loops is modified by providing a digital controlled wire feeding accessory. The accessory permits the normal mechanical feeding of the wire and tooling to be interrupted for desired intervals during the spring forming process thereby allowing digital controlled wire feeding to occur. The digital controlled wire feeding enhances the normal operation of the apparatus by allowing specified lengths of wire to be added to the coiled body portions and/or end loops of the manufactured spring.

  • Patent number: 4586916
    Abstract: Apparatus for separating folded two-on cartons is characterized by a carton supply station for advancing cartons seriatim to a separating station. At the separating station, opposite edges of each carton are gripped and first moved away from each other to pull the two-on carton apart into two separate cartons, and then moved toward each other to bring the separated cartons back together. The separated cartons are then conveyed out of the separating station while the supply station simultaneously advances the next successive two-on carton to the separating station.

  • Patent number: 4584862
    Abstract: A method for reducing the thickness of a slab of metal under conditions which tend to cause alligator defects to occur. The method comprises the steps of directing a relatively thick slab of metal several times through a rolling mill or mills to incrementally reduce the thickness of the slab until the thickness approaches a value that tends to produce a longitudinal and lateral fracture in one or both ends of the slab. The thickness of the slab is further reduced by passing the same several times again through a rolling mill or mills, with each of the passes of the slab taking a decreasing amount of reduction in thickness until a predetermined thickness value is reached. The next step involves passing the slab again through a rolling mill to further reduce the thickness thereof, the amount of reduction in this step and pass being substantially greater than that of the last pass immediately preceding this step.

  • Patent number: 4585221
    Abstract: A machine wherein flat blanks are fed from a stack thereof to be folded and glued into envelopes. The machine is provided with an optical sensing device which is operable to sense when the stack of blanks diminishes to a predetermined height whereupon the machine will be turned off automatically so as to prevent a plurality of blanks from being simultaneously fed into the machine from the diminished stack to jam the machine. The machine operator can then add blanks to the stack and restart the machine. The sensing device can be turned off by the operator in order to run all of the blanks in the stack through the machine at the end of a blank run or at the end of a working day.

  • Patent number: 4584915
    Abstract: A device imparts a predetermined motion to an object by using a cam. The device comprises a load compensator disposed at any desired position in a driven section and adapted to apply a force or torque to the driven section in order to counterbalance variations in the force of contact between a cam and a cam follower. The variations are caused by the movement of the driven section. The force of contact is maintained at a constant value, and enables the achievement of stabilized high-precision motion of the cam driven system, particularly the achievement of high-precision high-speed machining of the lead on a VTR lower cylinder by using an end cam.

  • Patent number: 4583574
    Abstract: Disclosed is a flaker for trunk and residual wood for the direct production of a mass of chips free of splinters and low in fines. Flaking takes place within a blade rotor equipped with a replaceable blade ring, which together with its housing may be moved back and forth in front of the outlet of a wood feed chute equipped with pressure elements. A compression chamber is located inside the blade ring, in which the wood to be cut intermittently abuts against a counter support. The compression chamber is equipped with additional pressure elements in order to hold the wood substantially still and without fluttering, until it is cut, without leaving a residue, even in the case of wood of large cutting width. The additional pressure elements act transversely to the counter support. A stationary, slightly raised entrance barrier is arranged directly in front of the compression chamber.

  • Patent number: 4583964
    Abstract: A method and an apparatus are indicated for the production of a cylindrical packing tube which is open at one end and closed at the other, is made from deformable tear-resistant packing material and is intended, in particular, for tampons used in female hygiene, wherein a portion of the packing material is drawn by suction onto a winding spindle provided with suction apertures and through the rotation of the winding spindle is wrapped around the latter, while the overlapping ends of the portion are joined together to form the packing tube, whose end projecting beyond the winding spindle is closed, whereupon the packing tube is removed from the winding spindle. The method is characterized in that that end of the cylindrical packing tube which projects beyond the winding spindle is held fast and during the rotation of the winding spindle is closed so as to form a twist. The method permits the production of a uniform closure pattern of the packing tube irrespective of the shape of the tampon insertion end.

  • Patent number: 4583391
    Abstract: A simple, rugged, and conveniently front-adjustable gage stop having a gage finger capable of presenting a gage face in any of several angular orientations is disclosed. The gage stop comprises a gage finger adjustably and rotatably connected to a finger support which is in turn pivotally connected to a mounting member. In operation, a workpiece is butted against the gage face with the gage stop resting in a horizontal orientation, and some operation is performed on the workpiece. If this operation results in an upward force being applied to the gage stop, the stop swings upward in response, to a limiting position in which the center of gravity of the finger support/gage finger combination is forward of the pivot axis, and then returns by gravity to a horizontal position.
