A spring washer improves resistance to loosening of fasteners tightened thereon. The spring washer is stronger than prior art devices. On the upper and lower surfaces of the spring washer, approximately 1/5-1/4 of the width inward from the outer perimeter is formed without V-shaped grooves. The remaining flat portions are formed with V-shaped grooves in various patterns. These V-shaped grooves increase the coefficient of friction and resist loosening of the spring washer. |

One side of a sheet- or plate-like bank of metallic, plastic and/or other material is provided with at least one set of parallel grooves prior to being provided with an array of pyramidal and/or conical depressions. The grooves can be formed by brushes or by grinding, and the depressions can be formed by a rotary debossing tool having a peripheral surface provided with crossing transversely extending rows and circumferentially extending columns of protuberances. The treatment enhances the ability of the one side of the thus obtained sheet- or plate-like body to accept and retain a layer of lacquer, to be provided with an adherent layer of oxide or to accept a layer of adhesive prior to being bonded to a similarly treated or to an untreated second plate- or sheet-like body. The depth of the depressions can match or approximate the average depth of the grooves. The grooves can form two sets of parallel grooves, and the grooves of one set can cross the grooves of each other set at an angle of 90.+-.45. |

A process and machine for automatically matching at least two substantially cylindrical surfaces for engaging each other, particularly for the purpose of mechanical embossment engraving. The ranges of freedom of a conventional machine are mechanized and subjected to an electronic control, providing a hardware structure driven by software. The software controls the starting, repetitive and final steps, automatically complying with spacing and timing. The operator's action is needed only for loading of the roll to be worked, setting the inherent knurling tool, setting the starting positioning, and starting the cycle, as well as, for removing the unfinished roll for the corrosion steps and of course for final unloading. |

A method of mechanically imparting a surface texture to a bland surface of sheet metal, especially soft aluminum, in which an adherent foil is applied at least to one surface of the sheet metal and is pressed into and against a surface by a roll so that the sheet metal is deformed and the pattern of the deformed foil is pressed into the sheet metal surface. |

An optical metrological scale produced by a rolling method, to give a profiled upper scale surface which is imparted by an embossing roller. To prevent uneven strains, which could affect the pitch of the scale, the support roller has a similar embossing profile, so that the lower side of the scale is also given a profiled surface. The embossing roller is freely rotatable, while the support roller is driven. |

A preassembled set of embossing rolls is shown. The embossing roll assembly is completed and tested at a work station away from a press line and thereafter the assembled set of rolls is transported to the press line for installation whereby down time on the press is avoided while the precision assembly of the matched pair of rollers is accomplished elsewhere. |

TISHKEN PAUL |
An apparatus for cold forming grating material from elongated, generally flat workstock, comprising a generally cylindrically shaped element having a series of outwardly directed projections thereon, means for rotatably supporting the element, guide means for guiding the workstock into peripheral engagement with the element whereby rotation thereof will cause the projections to be forced into the adjacent portion of the workstock to form a series of adjacently oriented, inwardly extending recesses or notched portions therein, and means including roller means for straightening and flattening the workstock after the series of notches are formed therein.
