Surface arrangement on the lid of 'flat cards "or cards.

The invention relates to a surface arrangement on the cover of flat cards or cards for attaching a card clothing.

With the flat cards, the carding of the pastes on the reel is done with the help of fixed or, if necessary, themselves slowly moving lid.

Recently, the lids have been grounded in particular with steel wires provided, which are attached to their concave surface. The surface is very precise according to the assigned drum, so that the carding is successful over the entire surface of the lid is even.

It is difficult to achieve the exact shape of the surface. This is especially true for the production of Lids for wide cards more than one meter wide with an accuracy of one hundredth of a millimeter,

In a known surface arrangement, for example, extruded aluminum profiles are used. This solution is disadvantageous. On the one hand, it is very complex. On the other hand, the strength properties of the lid are inadequate.

The invention is therefore based on the object of addressing the disadvantages of the known surface arrangement on the cover of flat cards or to avoid carding and to create one that is low in effort and combines with sufficient strengths of the lid.

The object is achieved according to the invention in that the surface is directly or indirectly on a plastic layer is arranged, which is attached to the base body of the lid against a predetermined the exact course of the surface Molded body, for example a drum, is cast on.

The invention has the advantage that the cover or its base body is only made relatively roughly can be and the plastic after curing then the surface with the exact course corresponding to the molded body or tambour specifies. In this way, however, the strength properties of the Cover guaranteed.

Other features and advantages of the invention are one Referring to the embodiment that is shown in the drawing and is described in more detail below.

The shaped body formed in particular by a drum has the one desired on the surface 4 a of the lid 2

Radius of curvature E. The base 3 of the cover 2, which can be of "any desired construction" is at a certain distance from the surface of the shaped body 1 temporarily fixed, and the gap thus cut out becomes self-hardening Plastic 4 poured out. In this case, it can optionally also be a plastic that forms hard foam Act. After curing, the plastic layer 4 has the desired exact course of the surface 4 a of the lid 2 corresponding to the molded body 1.

For stronger attachment of the plastic layer 4 on the G-round body 3 of the cover 2 are on the surface 3 a of the G-round body holding iron 5 arranged, which when Cast on by the plastic 4 are enclosed. Instead of the Bracing irons or in addition to these can not in; as shown in the surface 3 a of the G-round body 3 of the lid 2 when casting on from the. Plastic to be filled in, for example dovetail-shaped trained recesses are provided.

On the generated after the hardening of the plastic 4 Surface 4 a of the lid 2 can be attached directly or indirectly to the most diverse G-arnitüren will.
