  • Patent number: 6544457
    Abstract: An injection molding apparatus for manufacturing dental floss holders has at least one strand of dental floss from a supply spool extended through the space between mating mold pieces and thereafter to a take-up device. From each injection stage of the molding cycle a rack of connected dental floss holders is produced. Tension of the floss is maintained from the upstream supply spool by a first tensioning device through the mold to the downstream end by the take-up device. During each injection cycle the take-up device engages another rack of molded parts and moves it to a downstream position where it is severed from the strand of floss while it maintains the tension in the floss upstream of the severed rack. This is achieved by the take-up device engaging at least two successive racks downstream of the mold and using the rack closest to the mold to maintain tension.

  • Publication number: 20020180076
    Abstract: A method and apparatus for continuously forming flexible mat structure in the form of spaced, interconnected concrete panels. The mat structure can serve as an erosion control mat along the banks of waterways and within drainage ditches and channels, and can also be utilized to provide temporary or permanent walkways and roadways. A rotatable drum includes peripherally-positioned mold cavities that receive concrete mix from a trough supplied from a source of concrete mix. A grid is fed against the drum periphery and over the mold cavities before the concrete mix is introduced, and after the mix is introduced a web of fibrous material is brought into contact with the concrete-mix-containing mold cavities to overlie the concrete-containing surface of the drum. As the drum rotates the fibrous material with overlying, interconnected concrete panels is deposited on the ground to provide the finished mat structure.

  • Patent number: 6440348
    Abstract: The invention seeks to provide an improved method for producing umbrella-type insulators comprising a core which is configured as a full body or a hollow cavity and umbrellas connected thereto, whereby problem-free de-moulding of said umbrella-type elements is guaranteed despite the fact that a vacuum is formed. This is achieved by fact that the mould (5) is used with at least one valve (8) which is arranged laterally and which extends as far as the surface (4.2) of the umbrella elements or sleeve (4). Immediately after the beginning or during axial movement of the mould (5) away from the umbrella-type element (3) with a sleeve (4), a gas medium is automatically introduced into the cavity (9) which is formed between the core (2) and umbrella-type element (3) with a sleeve (4) and the mould (5) or the valve (S) opens under the effect of traction or pressure and the gaseous medium is thus introduced into the hollow cavity (9).
