Patents by Inventor Mark Reinhard BERLIN

Mark Reinhard BERLIN has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11618183
    Abstract: A process for the production of a fibre-composite material, the process including the following steps: a) a fibre bundle is conducted over at least one deflection bar having radially circumferential rounded elevations, thus being expanded; b) the expanded fibre bundle is subsequently drawn into an impregnation chamber; c) a melt is applied to the expanded fibre bundle; and d) the fibre bundle impregnated with melt is drawn through a take-off die at the end of the apparatus, and a corresponding device, which achieves very good impregnation quality.

  • Patent number: 10836136
    Abstract: By use of a process for the production of a fibre-composite material, comprising the following steps: a) one or more fibre bundle(s) is/are drawn by way of one or more spreader device(s) into an impregnation chamber in such a way as to give at least two mutually superposed, spatially separate and spread fibre webs; b) melt is introduced by way of horizontally oriented distributor bars, in each case arranged between two fibre webs; c) the individual fibre webs are caused to converge in such a way that they are mutually superposed and contact one another; d) after the fibre webs have converged they are drawn, at the end of the operating unit, through a take-off die where the first shaping takes place, and also by use of a corresponding device, very good impregnation quality is achieved through a specific wetting method implemented after a high degree of expanding, and also through subsequent relative longitudinal and transverse movements of the individual fibres.

  • Patent number: 10596772
    Abstract: The present invention relates to a novel process for the production of novel fibre-reinforced profile materials filled with a rigid foam core, especially a PMI foam core. In particular, the present invention relates to a novel process which, in various versions, provides a particularly high throughput and allows a very wide range of shaping options. One step here continuously produces a complex fibre-reinforced profile material and simultaneously inserts the rigid foam core into same. In addition, in the same process step, very good binding of the rigid foam core to the fibre-reinforced profile material is assured. Shaping further takes place in two or more moulds simultaneously to achieve a particularly high throughput and simultaneously produce profile materials differing in shape.

  • Patent number: 10576663
    Abstract: Very good impregnation quality is achieved by a process for production of a fiber-composite material, with introducing a fiber layer by a spreader device and thus spreading to a width greater than that of the final product, at least by a factor of 1.2, where the extent of spreading of the fiber layer is such that its average thickness is 1 to 50 times the filament diameter; applying a melt by at least one applicator nozzle to the spread material; by virtue of cross-section-narrowing, the mould brings the width of the wetted fiber layer at least to the cross section with which the product leaves the take-off die; a radius then deflects the wetted fibers by an angle of 5 to 60°; a relaxation zone renders the fiber distribution more uniform to give a uniform height; achieving the first shaping by a take-off die at the end of the mould.
