Patent number: 11701812Abstract: Aspects disclosed herein relate to forming on a substrate fastener elements suitable for use in touch fastener by employing vibration forming methods. The processes described provide for a greater flexibility in manufacturing than prior methods and overcome certain limitations in prior forming techniques. Further, the product made can embody a variety of different configurations suitable for a given application. Employing vibration forming methods, such as ultrasonic forming methods, allows for the use of a wider variety of substrate material than materials used with convention methods of touch fastener formation.Type: GrantFiled: March 17, 2021Date of Patent: July 18, 2023Assignee: Soni-Form, LLC.Inventor: Gerald Rocha

Patent number: 4629858Abstract: Methods for engraving carpet with beams of radiant energy. A beam of radiant energy, such as a laser beam, is intermittently directed at the surface of carpet to engrave the surface, and, if desired, to cause certain color changes. During the intermittent operation of the beam, the carpet is indexed to allow the beam to engrave designs. Alternatively, the beam may be indexed in relation to stationary carpet by means of lenses or mirrors to engrave designs. The method allows inexpensive and accurate engraving of carpet surfaces by which intricate designs may be formed on those surfaces in a minimum amount of time.Type: GrantFiled: December 12, 1983Date of Patent: December 16, 1986Assignee: Interface Flooring Systems, Inc.Inventor: Joseph H.
