The invention relates to a method for manufacturing vacuum insulation panels with a fiber core, comprising the steps of: providing a core blank of fibers, compressing the core blank to a predetermined final thickness for forming the core, evacuating a foil sleeve enclosing the core up to a pressure of ≦1 mbar, and sealing the foil sleeve. The method according to the invention is characterized by the fact that, in the compression step, the core blank is arranged between two cover elements and is mechanically compressed therebetween, that the core is kept under compression pressure until the foil sleeve is sealed, and that the compression step is performed at the place of manufacture at room temperature without thermal impact. Thus, a method for manufacturing vacuum insulation panels with a fiber core can be improved such that it can be performed with reduced energy requirement and yet the insulating effect of the vacuum insulation panels does not suffer therefrom.

摘要:
The invention relates to an improvement for applying a layered structure (1) onto a convex surface of a lens (10). After thermoforming the layered structure, a curvature direction of the layered structure is inverted. The structure is then applied on the lens surface by continuously pushing the structure (1) against the lens surface, starting from a contact point between a convex surface of the structure and the convex surface of the lens. The curvature direction of the layered structure is then inverted again, so that it recovers the curvature direction that resulted from thermoforming. Stresses within the layered structure are then reduced, and the structure can be assembled with the lens without defects.

A laminator (10, 100) in accordance with the invention includes an infeed (12) which supplies plastic cards which are to be laminated with a plastic laminating material on a first side (18) of each card; a laminating station (20) having a heated roller (22, 114) and a card support (24, 112), opposed to the heated roller, which supports a second side of each card and is separated from the heated roller to define a card opening (28, 116) through which each plastic card passes when being laminated; a laminate source (32) which feeds plastic laminating material into the card opening between the heated roller and the first side of each plastic card with heat from the heated roller heating the plastic laminating material and each plastic card in the card opening to fuse the plastic laminating material to the first surface of each plastic card; and a card bowing the station (40), which bows each card sufficiently in a portion thereof to cause each card when cooled to be substantially flat.
摘要:
The invention relates to a method for producing sandwich components comprising an open core structure (2) and cover layers (1, 3) that are applied to both sides, said layers (1, 3) being formed using a curable plastic material and the sandwich component being cured under pressure in a closed device. According to the invention, a filling gas, in particular nitrogen or air, is introduced into the core structure (2) prior to the at least partial solidification of the cover layers (1,3) and a filling gas pressure p Filling gas is selected that is less than or equal to the working pressure p Working of the closed device, notably to prevent to a great extent the formation of sink marks in the cover layers (1, 3). The control of the filling gas pressure p Filling gas of the filling gas in the core structure (2) in an appropriate manner during the curing process of the sandwich component enables sandwich components with almost optimum surface characteristics to be produced, in particular without the formation of sink marks in the cover layers (1, 3) of the core structure (2), (which are often caused by a negative pressure that occurs in the cells of the core structure (2) as a result of the cooling process). This obviates the need for the previously required complex mechanical after-treatment of the sandwich component, for example by grinding or filling. The invention also relates to a press for carrying out said method.
