  • Publication number: 20140174306
    Abstract: The invention relates to a method for hot stamping at least part of at least one band-shaped stamping foil (10, 20) onto a band-shaped substrate (30), as well as a corresponding hot stamping device. The substrate (30) to be stamped is brought together with one stamping foil (10, 20) of the at least one stamping foils (10, 20). The substrate (30) and the stamping foil (10, 20) resting thereon are guided along the periphery of a first heated stamping roller wherein, in a first stamping, a first stamping layer is stamped onto the substrate (30). The once-stamped substrate (30) is guided away from the first stamping roller and again brought together with the same or a further stamping foil (10, 20) of the at least one stamping foils (10, 20) after the first stamping roller in the direction of travel (33) of the substrate (30).

  • Publication number: 20010013282
    Abstract: Holographic labels are used on a variety of articles of manufacture for security, authenticity, or aesthetic appeal. Manufacturing a holographic label or sticker typically entails microembossing, that is, imprinting or cutting, microscopic grooves into a clear plastic sheet with a shiny aluminum coating. The grooves diffract light and form a three-dimensional image, such as the dove commonly found on Visa™ brand credit cards. Unfortunately, conventional microembossing machines, or microembossers, suffer from a number of problems. For example, these microembossers include two large base rollers that move back and forth in sequence to contact a shimroller. The clumsy back and forth movement not only limits how fast embossing can occur but also causes misalignment of embossed images. To address this and other problems, the inventors devised an exemplary microembosser which includes a single base roller and a shimroller which one or more unique features.

  • Patent number: 5115737
    Abstract: A continuous sheet of metal leaf advanced at a constant rate is moved at variable velocity through a rotary die stamper such that between stamps the metal leaf moves at a velocity which is slower than the velocity of a substrate web; but just prior to stamping the metal leaf is accelerated by contact between the metal leaf and a raised die rotating at the velocity of the substrate web so that when the stamp occurs the metal leaf is traveling at a velocity substantially equal to the velocity of the substrate web. Varying the velocity of the metal leaf has the effect of minimizing the distance the metal leaf travels between stamps which conserves consumption of the metal leaf. Separate means for accelerating the leaf prior to stamping and decelerating the leaf after stamping also may be provided.

  • Patent number: 4104965
    Abstract: A special-purpose clutch incorporated in a drive mechanism of hot stamping apparatus wherein heated type on a rotary type carrier is periodically pressed against a printing ribbon in superposition on a continuous strip of plastics or other material being fed at constant speed over a platen, thereby imprinting characters on the strip at constant spacings. The clutch comprises a drive disk mounted on a motor output shaft, a driven disk mounted on a type carrier shaft, and a spring through which rotation is normally imparted from the drive to driven disk. The spring is yieldable to permit the driven disk to be rotated, while the heated type is being pressed each time against the printing ribbon, by the strip of material at lower speed than the drive disk. The angular speed of the type being pressed against the ribbon can thus be precisely synchronized with the linear speed of the strip traveling over the platen.

  • Patent number: 4063500
    Abstract: For imprinting characters on a continuous strip of plastics or other material by pressing heated type against a printing ribbon thereon, the strip is fed at constant speed over a platen in a direction opposite to the direction of travel of the printing ribbon from payoff reel to takeup reel. The type is mounted on a rotary type carrier over the platen, for revolution in a direction in conformity with the traveling direction of the strip. While the heated type is being pressed against the superposed ribbon and strip over the platen, the ribbon is thereby transported a predetermined distance toward the payoff reel with the strip relative to the platen and, when subsequently released by the type, is pulled back the same distance toward the takeup reel by a spring-energized pullback lever. The ribbon is then wound up onto the takeup reel via a pair of drawoff rollers just by a length corresponding to the width of the character or characters on the typeface.

  • Patent number: 4007767
    Abstract: A process for highspeed branding of an intricate pattern, usually a wood grain pattern, into materials such as particle board, hard board or various lumbers having poor grain characteristics is disclosed. The material to be branded is passed under a heated rotary die having the desired pattern thereon to emboss by heat shrinking and to char the pattern into the material; and the improvement of the process of the present invention, which effects an increased die life, is comprised of maintaining the die at about a temperature between about and about F. This temperature range is high enough to achieve high quality branding and high quantity production, while minimizing degradation of the die pattern from oxidation and contact with the material being branded. The die pattern is preferably relatively deep, in excess of 0.040 inch, and is urged into the material to a depth of about one-half the pattern depth.
