Abstract
The invention describes a web-like element (2;3) comprising an upper layer (5; 7) and a lower layer (6; 8) or an intermediate layer which are held apart from one another vertically by longitudinal ribs. At least the upper layer (5; 7) is formed from several strip-like webs (16-19; 20-24) with a rectangular cross section which run parallel to one another on the longitudinal ribs and lie with their flat sides in a common plane. The strip-like webs (16-19; 20-24) are arranged at right angles to the longitudinal axis or the longitudinal ribs and/or in longitudinal direction with equal spacing (14).
Claims31
A web-shaped element extending in a longitudinal direction and comprising
- (a) a corrugated layer comprised of several ribs extending in the longitudinal direction, the ribs forming elevations and depressions of the corrugated layer, the elevations and depressions being spaced from each other at equal distances in a direction extending perpendicularly to the longitudinal direction, and the elevations and depressions defining therebetween a height of the corrugated layer, and
- (b) an upper layer comprised of several rectangular, strip-shaped webs defining a common plane,
- (1) the ribs being inclined towards each other and the common plane, and
- (2) a respective one of the rectangular, strip-shaped webs being arranged on each two adjacent ones of the ribs and projecting therefrom on both sides in the perpendicularly extending direction, the rectangular, strip-shaped webs being secured to the elevations of the corrugated layer in connection regions.
A web-shaped element extending in a longitudinal direction and comprising
- (a) a lower layer,
- (b) several ribs extending in the longitudinal direction, the ribs forming elevations and being spaced from each other at equal distances in a direction extending perpendicularly to the longitudinal direction,
- (1) the elevations and the lower layer defining therebetween a height of the ribs, and
- (2) the ribs being secured to the lower layer, and
- (c) an upper layer comprised of several rectangular, strip-shaped webs defining a common plane,
- (1) the ribs being inclined towards each other and the common plane, and
- (2) a respective one of the rectangular, strip-shaped webs being arranged on each two adjacent ones of the ribs and projecting therefrom on both sides in the perpendicularly extending direction,
- (3) the rectangular, strip-shaped webs being secured to the elevations of the ribs in connection regions.
Web-shaped element made of corrugated cardboard with a corrugated layer made of paper or cardboard and an upper layer made of paper or cardboard secured by a layer of glue onto elevations of the corrugated layer and a lower layer or intermediate layer made of paper or cardboard also secured by a layer of glue onto depressions of the corrugated layer opposite said elevations, characterized in that at least the upper layer is cut in the region of the depressions lying between the elevations, or the upper layer is formed by webs on the elevations running in their longitudinal direction, which are arranged spaced apart from one another at right angles to their longitudinal direction.
Connecting arrangement between a first web-shaped element with an upper layer and a lower layer spaced apart therefrom in height and several longitudinal ribs arranged perpendicular thereto and between the latter with equal spacing and aligned parallel relative to one another, the upper layer being formed from several strip-shaped webs or web parts with a rectangular cross section which run parallel to one another on the longitudinal ribs and lie with their flat sides in a common plane and project on both sides over the longitudinal ribs at right angles to their longitudinal extension and a second web-shaped element, characterized in that the second web-shaped element is made of plastic or wood, and for mounting the webs or web parts, is provided with grooved recesses arranged with the same spacing extending parallel to the longitudinal direction of the longitudinal ribs, and the recesses are designed to be U- or C-shaped in a plane perpendicular to the longitudinal direction thereof, and in that a width of the recesses is equal to or smaller than the web width of the webs or web parts.
Connecting arrangement between two web-shaped elements with respectively several longitudinal ribs extending in a longitudinal direction, whereby on elevations thereof at least several rectangular, strip-shaped webs or web parts of an upper layer are arranged with their flat sides in a common plane, and the latter project on both sides respectively over the longitudinal ribs at right angles to their longitudinal extension and two immediately adjacent webs or web parts at right angles to their longitudinal extension are spaced apart from one another and arranged with equal spacing from one another, characterized in that with the first or second web-shaped element, the longitudinal ribs in cross section are inclined towards the upper layer and to one another and form a corrugated layer with elevations and depressions, and in that on two longitudinal ribs forming the corrugated layer a strip-shaped web or web part is arranged and the webs or web parts are secured onto the elevations of the corrugated layer in connecting regions and the elevations and depressions are arranged spaced apart from one another in height, and in that the projection projecting over the connecting region forms a linking part of the connecting arrangement, the linking parts of the first element engaging behind the linking parts of the additional element on the side facing the lower layer or the intermediate layer or the corrugated layer.
Method for producing a web-shaped element in which a layer of plastic or paper or cardboard is applied onto a corrugated layer formed by parallel longitudinal ribs arranged on a lower layer and is glued thereon by an adhesive, characterized in that the longitudinal ribs are arranged inclined towards an upper layer to form the corrugated layer with elevations and depressions, and in that, once the glue has set, at least the upper layer is cut or partly removed in a direction parallel to the longitudinal ribs or the elevations or depressions and between said longitudinal ribs or elevations or depressions so that facing longitudinal side edges of webs or web parts are separated from one another and spaced apart.
